Biotin ●
TL;DR. This ingredient is used mainly as a hair and skin conditioning agent. It supports formulas positioned around softer feel, scalp care, and healthy-looking hair, rather than acting as a primary cleanser, emulsifier, or preservative.
What does Biotin do in a cosmetic formula?
This ingredient is used mainly as a hair and skin conditioning agent. It supports formulas positioned around softer feel, scalp care, and healthy-looking hair, rather than acting as a primary cleanser, emulsifier, or preservative.
Is Biotin clean?
This ingredient has a strong clean-beauty profile, with low irritation potential at cosmetic use levels and no major restricted-list friction. Sensitivity is uncommon in topical products, though it is usually present at very low levels.
Is Biotin sustainable?
This material may be made by fermentation or synthetic chemical routes, so its sustainability profile depends on the supplier and feedstock. It is used in tiny amounts and is not known for environmental persistence or bioaccumulation concerns.
Is Biotin COSMOS-approved?
This ingredient can fit COSMOS-natural and COSMOS-organic formulas when the source and manufacturing process meet the standard’s requirements. From a Green Chemistry view, fermentation-based supply and low-use levels are favorable, while fully synthetic routes are less aligned with renewable-feedstock goals.
How does Biotin work chemically?
The molecule is a water-soluble bicyclic ureido-thiophene carboxylic acid, which gives it good compatibility with aqueous phases. Typical cosmetic use levels are often about 0.0001% to 0.1%, and it is generally stable in mildly acidic to neutral formulas but less suited to strong oxidizers, strong acids or bases, and prolonged high heat.
