Function

ANTICAKING: Preventing agglomeration of particulate solids into lumps or hard masses (cohesive cake), thus allowing free flow of particles.
COLORANT: Exclusively or mainly intended to colour the cosmetic product, the body as a whole or certain parts thereof, by absorption or reflection of visible light. All authorised colorants are substances in the positive list of Annex IV to the Cosmetics Regulation 1223/2009.
SLIP MODIFIER: Enhancing the flow properties of other ingredients without reacting chemically with them.
VISCOSITY CONTROLLING: Increasing or decreasing the viscosity (thickness) of cosmetics.
