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.

Benefits
  • Gel-forming — creates characteristic lightweight gel textures
  • pH-controlled thickening
  • Transparent gel aesthetics
  • Stable across temperature extremes
  • Excellent suspension agent for actives and pigments
Example uses
  • Gel moisturisers
  • Water-gel serums
  • Sunscreen bases
  • K-beauty sleep masks
  • Tinted gel foundations
Formulation notes

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.

Watchouts

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.

Clean beauty perception

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.
