Reading an INCI List: A Brand Owner's Guide to Approving a Capsule Formula

An INCI list looks like a wall of Latin, but it is the most honest document in any skincare project. Every ingredient must appear by its International Nomenclature of Cosmetic Ingredients name, ordered from the highest concentration to the lowest, with anything present at 1% or below listed in any order after that point. For a brand owner preparing to sign off on a soft capsule formula, learning to read this list is the fastest way to understand what you are actually selling.

CapsulesBiotech manufactures single-dose soft capsules for overseas brands, across facial oil, eye serum, hair oil, body lotion, cream, and mask lines. Because every formula we fill is documented by its INCI declaration, buyers can review exactly what goes into the shell and what goes into the fill before tooling begins. That transparency protects your claim on the finished carton.

The first five names on a list usually carry the product. In an oil-based capsule, that means the carrier oils, such as caprylic/capric triglyceride, jojoba, or squalane, followed by the active. If a botanical you are paying a premium for sits near the bottom, the formula contains very little of it. Ask your manufacturer for the percentage of each key ingredient, not just its position, so you can judge whether the label story and the fill match.

A capsule has two components, and both appear on the declaration. The fill is your serum or oil, while the shell is listed separately when it is made from plant cellulose or food-grade gelatin. This matters for positioning: a 100% plant-based shell allows a vegan claim, while food-grade gelatin suits brands targeting traditional markets. Decide which shell you need early, because it shapes the wording of every downstream claim.

Single-dose sealing changes what has to be declared. Because each capsule is closed and protected from air and light, the fill does not require preservatives to survive on shelf, so the declaration stays shorter and easier to explain to buyers. Nothing is exposed between uses, dosage is fixed, and the format travels without leakage. For a brand comparing a jar against a capsule line, the difference shows up directly in the ingredient list.

Before signing a formula, run through these points with your supplier:

• Is the full INCI declaration provided in the exact order that will appear on the carton?
• What percentage does each hero ingredient occupy, and how is it measured?
• Which ingredients sit at or below 1%, and can any be moved without changing performance?
• Is the shell material declared separately, and does it support the claims you plan to make?
• Will the factory supply updated documentation if the formula changes after approval?

Clear answers keep both sides aligned. If a supplier cannot explain why an ingredient sits where it does, that is a signal worth taking seriously, and it usually surfaces before artwork is finalised rather than after.

Documentation also matters more than it used to. Regulators in several markets now expect ingredient data to match what is filed at product notification, and retailers increasingly run their own label audits. Keeping the declaration and the factory record in sync saves you from reprinting cartons or re-filing later.
