Aloe vera arrives in most briefs as a single line: an aloe base, a percentage on the front of the pack, a cost target. The quote that comes back is rarely that simple. Aloe is traded in a handful of commercial grades, those grades differ in solids content, in colour, in odour, in documentation depth & in price by a wide margin, & the grade a factory prices is usually the grade it can source at the volume the brand is asking for rather than the one the brief imagined. A specification that says "20% aloe vera" can be met four different ways at four different costs, with four different ingredient names printed on the back of the pack.
This piece covers the grade families a supplier will offer, what the concentration markings on a raw material datasheet actually mean, the specification lines that separate one grade from another, the assay methods behind those lines & what each one can & cannot show, how grade choice moves both cost & lead time, what a given grade does to viscosity, colour, odour & preservation inside the formula, the INCI names that follow from each grade, the label wording a brand can & cannot use, & the sampling & documentation package worth asking for before a purchase order is signed. It is written for the person who signs the raw material specification rather than for the chemist who weighs it.
Why "aloe" is not one ingredient
The first variable is the part of the leaf. An inner-leaf or fillet juice is pressed from the gel that sits inside the leaf; a whole-leaf juice is ground from the entire leaf including the rind. The rind carries the anthraquinone fraction, the group of compounds that includes aloin & aloemodin, & that fraction is the reason a whole-leaf raw material is normally put through a decolourising & polishing step before it is sold as a cosmetic grade. A specification that does not say which part of the leaf it wants will be quoted on whichever material the supplier happens to hold in stock, & the difference shows up later as a colour problem or as an impurity line the brand never expected to discuss.
The second variable is the water. A single-strength juice is a dilute material in which the great majority of the mass is water; a concentrate has had water removed under vacuum; a powder has had essentially all of it removed, either by spray drying or by freeze drying. Each step changes what the material can be called on a label, how many kilograms are needed to deliver a given solids level into the finished product, & how much it costs to ship per kilogram of actual plant solids rather than per kilogram of water. Two materials with the same stated percentage can represent very different amounts of the plant.
The third variable is what was added on the way. Spray-dried powders are frequently produced with a carrier, because a juice with a high sugar content does not dry into a free-flowing powder on its own; the carrier is usually a maltodextrin or a similar glucose polymer, & whether it is declared depends on the supplier & on the grade. A powder described only by its concentration ratio can therefore be a material in which a meaningful share of the mass has nothing to do with the plant, & that share is invisible to any assay that responds to polysaccharide in general rather than to the plant in particular. This is the single most common source of a price gap between two quotes for the same raw material name.
The grade families a supplier will offer
A single-strength inner-leaf juice is the reference material. It is pale, it carries a characteristic hay-like odour, it has a low solids level, & it is preserved at the point of production because it will not hold without preservation. It ships in drums or in intermediate bulk containers, it is usually moved & stored under temperature guidance, & it has a defined shelf life that is shorter than most of the other ingredients in a skincare formula. A brand that wants this material is buying water as well as plant, & paying freight on both.
A concentrated juice is the same material with water removed, sold as a multiple of the single-strength material. A decolourised grade is a whole-leaf or inner-leaf juice put through activated carbon & filtration to strip colour, to reduce odour & to bring the anthraquinone fraction down to the level the specification sets. Decolourisation is an extra process step with an extra cost, & it is the grade most often specified where the finished product is a clear gel, a clear toner or anything filled into a transparent bottle, because the natural colour of an unprocessed juice is visible at the percentages brands like to print on the front of the pack.
On the dry side, a spray-dried powder is the workhorse grade & the cheapest per kilogram of declared concentration; a freeze-dried powder costs more & is generally specified where the buyer wants a process that avoids the sustained heat of a spray tower. A reconstituted juice is a powder dispersed back into water, sold as a liquid. That last option is the one to watch, because a reconstituted material can be presented as a juice while its documentation records a powder, & the label name that follows is decided by the documented material rather than by the form it is delivered in.
What the concentration markings actually mean
A marking of 10x means ten parts of single-strength juice reduced to one part of concentrate. A marking of 100x on a powder means one hundred parts of juice taken down to one part of powder. The figure is a mass concentration ratio. It describes how much water was removed & nothing else. It is not a measure of the polysaccharide content, it is not a measure of the fraction of the material that came from the plant, & it says nothing about whether the drying step damaged the material, which is why two powders both marked 200x can behave differently in the same formula.
The reconstruction arithmetic is where briefs go wrong. One kilogram of 200x powder dispersed into one hundred & ninety-nine kilograms of water is often described as two hundred kilograms of juice. That is true as a mass ratio only if the drying step retained everything the juice contained, & no thermal process does. The material that comes back has lost volatile components, has a modified polysaccharide profile & carries whatever carrier the drying step needed. Describing it on a pack as the equivalent of fresh juice is a wording decision with regulatory consequences in most markets, & it is not a wording decision a factory can make for the brand.
The practical fix is to specify the material rather than the multiple. Ask for the solids content on the certificate of analysis, ask for the polysaccharide figure with the method named, ask whether a carrier was used & at what level, & ask what the supplier's own declaration of the reconstitution ratio is. A specification written in those terms can be compared between suppliers; a specification written as "aloe 200x, 20%" cannot, because each supplier reads the second half of that line differently.
The specification lines that separate grades
Identity & composition come first. The botanical name with the plant part, the country of origin, the form, the solids or Brix figure with its method, the pH, the viscosity where the material is liquid, & the polysaccharide content expressed on a stated basis with the assay method named alongside. Those five or six lines are what make a material comparable between two quotes. Everything else on a certificate of analysis is either a safety line or a handling line, & both matter, but neither tells a buyer what the material will do in the mixing vessel.
The safety lines are the ones a purchasing team usually asks about only after a problem. Heavy metals, pesticide residues where the agricultural origin makes that relevant, the anthraquinone fraction expressed on a dry solids basis, the microbiological counts, & the residual solvent figure where a process used one. None of these have a single universal number; each is a limit set between brand, factory & supplier against the destination market, & the limit is only meaningful when the basis is stated, because a figure expressed on dry solids & the same figure expressed on the liquid material differ by more than an order of magnitude.
The handling lines are the ones that decide whether the material survives the supply chain. Pack size & material, shelf life, storage temperature, whether the material is preserved & with what, whether it is shipped ambient or under temperature control, & the sampling & retest arrangement. The preservation question is easy to miss & expensive to miss: a preserved raw material contributes its preservative to the finished formula, that contribution has to be counted against the total the brand is willing to declare, & in some markets the preservative in a raw material has to be named on the label even though the brand never chose it.
Assay methods & what each one shows
A solids or Brix reading is the cheapest line on a certificate of analysis & the least informative. It reports total dissolved material. It cannot distinguish plant solids from added sugars or from dissolved salts, & a supplier can hit a Brix target with material that contains very little of the plant. It is useful as a consistency check between lots of one grade, & it is not useful as an identity test.
A polysaccharide assay, typically a phenol–sulfuric acid method read on a spectrophotometer, is the most commonly quoted activity-adjacent figure. It responds to polysaccharide in general. Maltodextrin carrier, added sugars, & any gum in the blend will raise the reading, so a powder with a carrier can return a higher polysaccharide number than a cleaner powder with a lower declared concentration. A high figure on this method is a reason to ask a second question, not a reason to stop asking questions.
High-performance liquid chromatography against a reference standard is the method used for the anthraquinone fraction & for specific marker compounds, & it gives a number tied to a defined molecule rather than to a class. Nuclear magnetic resonance profiling & site-specific isotope analysis are used where authenticity is the question: they detect added sugars, they detect a synthetic acid being used to imitate the acid profile of the plant, & they are priced accordingly. The wider question of how a botanical is standardised & documented for cosmetic supply is set out in our note on herbal extract standardisation & documentation, which covers the same method-matching problem for other plant materials.
How grade choice moves cost
Freight is the first lever, & it is the one that surprises buyers who compare prices per kilogram. A single-strength juice is mostly water, so the price per kilogram looks attractive & the price per kilogram of plant solids is not. Once freight, drum disposal, temperature-controlled storage & the shorter shelf life are counted, a concentrate or a powder frequently lands cheaper per unit of delivered solids, even though its sticker price per kilogram is far higher. The comparison has to be made on a delivered-solids basis or it means nothing.
Minimum order & lead time form the second lever. A powder ships in bags with a minimum that is small in mass but can be large in value; a juice ships in drums or in intermediate containers with a minimum set by the container rather than by the material. Speciality grades such as freeze-dried powders or materials with a full authenticity package carry longer lead times & higher minimums, & a documentation package built for a specific market adds weeks to the first delivery. A launch date built on a grade with a twelve-week raw material lead time is a launch date that has already slipped.
The unit cost inversion is the third lever, & it is the one that makes a cheap grade expensive. If the brand wants a printed percentage of juice on the pack, a low-solids grade has to be dosed at a higher inclusion level to deliver the same solids, & that higher inclusion brings more water, more preservative demand, more colour & more odour into the formula. A cheaper concentrate used at a lower inclusion level can end up cheaper per finished unit than a cheap juice used at a high one. The only way to see this is to have the factory quote the same finished formula on two documented grades.
What the grade does inside the formula
Electrolytes are the first thing a formulator notices. A juice carries dissolved salts, & those salts collapse the viscosity of carbomer & of some other anionic thickeners. A formula built on carbomer can lose most of its structure when the aloe is added, & the usual answers are to move to an electrolyte-tolerant polymer, to pre-neutralise differently, or to restructure the water phase around the aloe from the start rather than adding it to a finished gel. A brand that specifies a texture without specifying the grade will be shown a reformulation later.
Heat & pH are the second pair. The polysaccharide fraction is sensitive to sustained high temperature, so a juice or a powder hydration is normally brought into the cool-down phase rather than held at the top of the heating cycle. The material is mildly acidic, which shifts the pH adjustment of the batch & therefore shifts the preservation window, because most preservative systems have a pH range inside which they work & outside which they do not. Neither of these is a problem if the process order is written down; both are a problem if the factory has to improvise.
Powder grades bring their own handling. A spray-dried powder needs time & shear to hydrate fully, it can form fish-eyes if it is added too fast, & an incompletely hydrated powder shows up as specks in a clear product & as a grainy feel in a cream. Cationic conditioning agents & some cationic polymers will interact with the anionic character of the polysaccharide fraction, & where a formula contains both, the order of addition & the compatibility check belong in the development record rather than in the memory of whoever ran the pilot batch.
Colour, odour & the clear-gel problem
An unprocessed juice is pale yellow to tan, & it darkens with heat, with time & with exposure to light. At the inclusion levels brands like to print, that colour is visible. A formula developed with a water-white laboratory sample & produced with a production lot of an unprocessed juice will not match, & the mismatch is read by a customer as the product having changed. Setting a colour limit on the incoming raw material is cheaper than setting it on the finished product, because the finished product has already been filled by the time the difference is noticed.
Odour is the companion problem. The material carries a hay-like, slightly sour note that is recognisable at low levels, & it intensifies as the product ages. The options are a decolourised & deodorised grade, a masking fragrance, or accepting the note as part of the product's character. Masking costs money in fragrance load, & fragrance load has its own constraints on the label & on the allergen declaration, so the decision is rarely free whichever way it goes.
Pack choice follows from the grade. A clear bottle shows the colour of the material & every change in it across the shelf life; an amber or opaque bottle hides the colour but also hides the product, which some brands want & others do not. Ultraviolet exposure accelerates colour drift, so a transparent pack in a bright retail environment is a harder specification to hold than the same formula in an opaque one. Where the brand wants transparency, the decolourised grade is usually the grade that makes it possible.
Preservation load in a high-water botanical base
A juice is water with dissolved sugars, & that is close to an ideal growth medium. It is preserved at the point of production for exactly that reason, & the preservative it arrives with becomes part of the preservation system of the finished product. That contribution is not always small. If the incoming material carries a preservative that is not part of the system the brand wants to declare, the factory is left either accepting it & naming it, or sourcing a grade preserved differently, which is a sourcing decision with a lead time attached to it.
The incoming bioburden specification is the control that keeps the finished preservation system honest. A total viable count & a yeast & mould count with limits, a stated method & a stated acceptance level, on every lot, is standard practice for a botanical water-phase material. Where a factory accepts a raw material on the supplier's certificate alone without a confirmatory count, a high-bioburden lot can consume the preservative capacity of the batch & the failure appears in stability rather than at goods-in.
The finished formula then needs its own preservation check rather than a preservative percentage copied from a similar product. Water activity, pH, the sugar load, the presence of a botanical & the pack all move the outcome, & a system that holds in a simple water phase can fail in an aloe-rich one. The check is run on the finished formula in the production pack, & it is one of the few development items worth insisting on before a pilot run rather than after it.
INCI names, percentage wording & the claim boundary
The grade dictates the name. A juice is declared as Aloe Barbadensis Leaf Juice; a dried material as Aloe Barbadensis Leaf Juice Powder; a material extracted with a solvent other than water as Aloe Barbadensis Leaf Extract; a steam-distilled or aqueous aromatic fraction as Aloe Barbadensis Leaf Water. A brand that approves a front-of-pack statement before the grade is fixed has approved wording that the back of the pack may not support, & the two are checked together by any competent reviewer.
Order of predominance does the rest. Ingredients above one per cent are listed in descending order, so a formula built on a low-solids grade at a high inclusion level can still list water first, because most of what was added was water. A brand that expects the plant name to appear at the top of the list needs a grade & an inclusion level that put it there, & that is a formulation target worth stating in the brief rather than discovering on the first printed carton. The naming & market-specific requirements behind this are covered in our note on INCI naming & ingredient safety across markets.
The wording boundary is the last piece. A botanical content statement is a factual claim about composition, & it has to be supportable by the documentation behind the grade. Wording that moves from composition into an outcome, or that implies a drug-type effect, sits outside cosmetic wording in most jurisdictions & will be read that way by a regulator, by a marketplace reviewer & by a retailer's own compliance team. The safe habit is to keep pack copy to what the material is & how the product feels, to keep the documentation ready to support the composition statement, & to have the exact wording checked against the destination market before the artwork is released to print.
Aloe grade variables at a glance
The table below sets the main grade choices against what each one changes, the trade-off a buyer should expect, & the point most often missed. The rows are a relative comparison drawn from common sourcing practice rather than fixed values, & the right grade for a specific product should be confirmed against the finished formula, the pack & the destination market.
| Grade | What it changes | Typical trade-off | Watch point |
|---|---|---|---|
| Single-strength inner-leaf juice | Simple declaration & familiar story | Freight on water, short shelf life | Mostly water, low plant solids |
| Concentrated juice | Lower freight per unit of solids | Higher price per kilogram | Reconstitution basis must be stated |
| Decolourised whole-leaf juice | Low colour & low odour in a clear pack | Extra process step, higher cost | Anthraquinone limit on a solids basis |
| Spray-dried powder | Long shelf life, ambient handling | Carrier may carry part of the mass | Polysaccharide assay reads the carrier |
| Freeze-dried powder | Avoids sustained drying heat | Higher cost, longer lead time | Hydration time & dispersion method |
| Reconstituted juice from powder | Liquid handling with powder economics | Label name follows the documented form | Do not describe it as fresh juice |
| Documentation package level | Authenticity & traceability evidence | Cost & lead time rise with depth | Two orthogonal methods beat one |
These are directions rather than settings. A grade that is right for an opaque cream can be wrong for a clear toner, because the same colour that is invisible in one pack is the first thing a customer sees in the other. The correct sequence is to fix the pack & the printed statement first, then the grade that can support them, & only then the inclusion level, which is the reverse of the order most briefs arrive in.
What to put in the brief
Name the material before the marketing number. A brief that opens with the grade, the documented form & the destination markets gets a quotable specification back; a brief that opens with a percentage gets four different quotes & a question. Then give the inclusion target, the pack, & the wording the brand intends to print, because those three together decide the grade rather than following from it.
- The grade & form: inner-leaf or whole leaf, juice, concentrate, decolourised, spray-dried or freeze-dried.
- The documented identity: botanical name with plant part, origin & the certificate of analysis lines required.
- The composition figures: solids or Brix, polysaccharide content & the assay method named with each.
- The carrier question: whether one was used, what it is & at what level it is declared.
- The impurity & safety lines: anthraquinone basis, heavy metals, microbial counts, residues.
- The preservation status of the raw material & whether its preservative may appear on the label.
- The inclusion target, the pack & the printed statement, so the grade can support the wording.
- The documentation depth: authenticity testing, allergen & origin statements, retention sample period.
Then confirm that the first pilot will be run on the production grade rather than on a laboratory sample, because a formula approved on one grade & filled on another is a different product wearing the same name. A brief that leaves the grade open is a brief that will be rewritten, & the rewrite is what costs the launch window rather than any single formulation question.
Where our capability fits
We take an aloe programme in the order set out above: the pack & the printed statement first, then the grade that can support them, then the developing formula built around the electrolytes & the pH the grade brings, then the preservation check on the finished product in the production pack. We ask the supplier for the certificate of analysis with the method named on every line, we record the grade, the lot & the supplier in the batch record alongside the formula version, & we hold retention samples in the primary pack so that a colour or odour drift several runs later can be compared against the approved unit rather than against memory.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & the grade decision is made alongside the label wording so the two support each other rather than being reconciled later. The same raw material documentation discipline runs across a custom aloe vera face mask programme, a chamomile hydrating face toner & a clear botanical toner in a bottle, where colour, odour & declaration matter in the same way.
Tell us the pack you want, the statement you intend to print & the quantity per SKU you are planning, & we will come back with the grade options, the documentation package each one supports & the sampling sequence.

General manufacturing information, not regulatory or legal advice. The grade names, the declaration rules & the composition statements permitted on a pack depend on the destination market, the botanical content of a raw material has to be supportable by the documentation behind it, & the applicable rules should be confirmed with the competent authority before artwork is released to print.
