The ingredient narratives reshaping clean beauty.
Carbomer
aka carbopol · acrylic acid polymer · polyacrylic acid · carbomer 940
Essential rheology modifier enabling the gel textures that define contemporary clean K-beauty moisturisers, essences, and water-gel hybrids. No skin-active function.
- Gel-forming — creates characteristic lightweight gel textures
- pH-controlled thickening
- Transparent gel aesthetics
- Stable across temperature extremes
- Excellent suspension agent for actives and pigments
- Gel moisturisers
- Water-gel serums
- Sunscreen bases
- K-beauty sleep masks
- Tinted gel foundations
Activated by neutralisation with a base (sodium hydroxide, triethanolamine) to target pH 6–7.5. Incompatible with high electrolyte concentrations (causes viscosity loss). Incompatible with strong acids, which collapse the gel structure.
No direct skin-active benefit — purely a rheology tool. PETA-flagged as animal-tested during cross-linked polymer development era; current in vitro safety assessments are standard. Petroleum-derived backbone though COSMOS-approved bio-based carbomers exist.
Neutral to slightly negative in strict natural/organic frameworks due to synthetic polymer backbone. Broadly accepted in clean beauty for its safety profile and functional necessity. EWG rating 1–2.
