About

A complex peptide-lipid hybrid ingredient conforming to a defined formula where R1 is C15 or C17 and R2 is C14 or C16, used as a skin conditioning agent in cosmetic formulations.

This is a synthetically modified serine derivative acylated with mixed C14–C17 aliphatic acid chains. The ingredient represents a hybrid of amino acid and long-chain fatty acid structures, designed to deliver skin conditioning benefits. No EU cosmetic restrictions apply to this ingredient, and its macromolecular nature suggests poor skin penetration, limiting systemic toxicity risk. Limited data exists specifically for this exact structure, but analogous compounds are well tolerated.

Skin benefits

  • Conditions and softens skin
  • May support skin barrier function due to lipid-like nature

Known concerns

  • No EU regulatory restrictions identified
  • Limited toxicology data specific to this exact acyl chain combination
  • High molecular weight limits skin absorption
