About

A hybrid silicone-polymer consisting of a bis-butyldimethicone backbone modified with polyglyceryl-3 side chains, functioning as a water-resistant emollient and emulsifier.

This bis-butyldimethicone polyglyceryl-3 polymer is used as a skin conditioning agent and emulsifier, offering both silicone-like smoothness and hydrophilicity from the glyceryl modification. PubChem records a safety score of 55, which is notably lower than most cosmetic polymers; the score likely reflects uncertainty around residual silanol groups or low-molecular-weight oligomers. The substance is not listed in EU Cosmetics Regulation Annexes II–VI, and no specific maximum concentration applies. Some cyclic siloxanes (e.g., D4, D5) are under regulatory scrutiny in the EU; this modified polymer is distinct but warrants awareness.

Skin benefits

  • Delivers water-resistant emollient protection
  • Combines silicone smoothness with glyceryl moisturisation
  • Improves formulation texture and spreadability

Known concerns

  • Lower PubChem safety score (55) warrants attention for residual oligomers
  • Contains siloxane bonds that have been subject to EU regulatory review
  • Possible residual low-molecular-weight siloxane species
