Formula IngredientThickenerSodium Carbomer
INCI: Sodium Carbomer
Sodium Carbomer is the pre-neutralised sodium salt form of carbomer (a crosslinked polyacrylic acid polymer). Unlike standard carbomer which requires base neutralisation, sodium carbomer forms viscous gels immediately upon addition to water. It functions as a viscosity controller, emulsion stabiliser, film former, and gel former in cosmetic formulations.
