About

A silicone polymer with two long-chain C30-45 alkyl substituents and an amodimethicone backbone, providing substantive film-forming and smoothing benefits in hair and skin products.

Bis-C30-45 Alkyl Amodimethicone is a high-molecular-weight organosilicone polymer used for its film-forming and barrier properties. The pubchem score of 55 reflects moderate safety considerations. Silicones of this type are not restricted under EU Annex regulations; however, environmental concerns about persistent siloxane accumulation in aquatic systems are increasingly reviewed under REACH.

Skin benefits

  • Long-lasting film formation
  • Smooth skin feel
  • Water repellency
  • Hair smoothing and anti-frizz

Known concerns

  • Environmental persistence of siloxane compounds
  • Potential aquatic toxicity for certain siloxane structures
  • Not biodegradable
