About

A block copolymer of PEG-100 and polycaprolactone with a sebacic acid core, functioning as a biodegradable polyester-PEG conjugate emollient with excellent skin compatibility and controlled-release properties.

Bis-(Methoxy PEG-100 Polyepsilon Caprolactone) Sebacate is a ABA-type block copolymer where A = methoxy PEG-100 and B = polyepsilon caprolactone, with sebacic acid as the central linking diacid. The polycaprolactone segment provides skin feel and biodegradability, while PEG-100 provides water solubility and humectancy. The high molecular weight ensures negligible skin penetration. Polycaprolactone is used in biomedical applications (biodegradable sutures) confirming its biocompatibility. The ingredient is used in advanced skin care and UV filter formulations. 1,4-dioxane residual from the PEG segment must be controlled per EU cosmetics standards.

Known concerns

  • PEG-100 component - 1,4-dioxane residual
  • High molecular weight polymer - negligible skin penetration
  • Generally excellent safety profile
