About

A hybrid conditioning agent combining cocoyl fatty chain, aminopropyl dimethyl quaternary group, and hydrolyzed collagen protein, providing substantive conditioning and film-building.

This is a complex multifunctional ingredient: a cocamidopropyl quaternary ammonium unit linked to a hydrolyzed collagen fragment via a hydroxypropyl spacer. The cocoyl (C8-C18, predominantly C12) chain provides hydrophobic substantivity; the collagen fragment adds protein-repair benefits; the quaternary ammonium provides permanent positive charge. EU CosIng shows no specific restriction for this ingredient class. Hydrolyzed collagen is widely used with established safety. However, residual protein fragments may trigger sensitivity in predisposed individuals, and the manufacturing process for combining these moieties is not fully standardized.

Skin benefits

  • Protein substantivity for damaged skin and hair
  • Film-forming action reducing friction and damage
  • Moisture-binding from collagen peptide fragments

Known concerns

  • Collagen protein allergen sensitivity
  • Residual formaldehyde from collagen hydrolysis process
  • Possible nitrosamine formation if secondary amines are present
  • Limited data on the specific cocamidopropyl-hydroxypropyl-collagen linkage
