About

Decarboxy rosin is a modified rosin (pine resin) derivative where carboxyl groups have been removed, resulting in a softer, more stable material used as a film-former and binder in cosmetics.

Decarboxy Rosin (also called depolymerised or modified rosin) is derived from rosin (colophony) obtained from pine trees. The decarboxylation process reduces the acidic nature of rosin, improving its stability and reducing potential skin irritation. Rosin itself is not specifically restricted in EU Regulation 1223/2009 Annexes II or III, though certain rosin-derived constituents can be contact allergens. Decarboxylated rosin has improved cosmetic compatibility compared to unmodified rosin, with reduced sensitisation potential. Used as a film-former, binder, and viscosity-controlling agent in lipsticks, mascaras, and other colour cosmetics.

  • Film-forming properties
  • Binder in colour cosmetics
  • Improves product stability

Known concerns

  • Minor risk of contact allergy compared to unmodified rosin
  • Still derived from natural rosin which can be an allergen
  • Quality varies by source and processing
