Carbomer
💚Very good
What it is
A group of synthetic high-molecular-weight polymers of acrylic acid. Used as thickening and gelling agents in cosmetics.
How it works
Carbomer molecules increase in volume when neutralized with a base (like sodium hydroxide), converting a liquid into a gel. This action provides viscosity and stability to cosmetic formulations, creating pleasant, non-tacky textures.
Formulation notes
Effective concentration: 0.1% - 1.0%
pH range: Requires neutralization to a pH of 6.0-7.5 for maximum viscosity.
Stability: Stable.
Safety
Irritancy: 0
Comedogenicity: 1
