LAUROYL HYDROLYZED COLLAGEN.

Valuable CAS 68920-59-2 / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

Lauroyl Hydrolyzed Collagen is a modified protein derivative designed to function as a sophisticated skin conditioning agent and humectant. It combines the well-known beneficial properties of hydrolyzed collagen with a lauroyl fatty acyl group, which is anticipated to enhance its affinity with the skin and potentially offer additional emollient benefits.

Science

Mechanism of Action

This ingredient operates primarily as a humectant and skin conditioner, analogous to conventional hydrolyzed collagen. Its constituent amino acids and oligopeptides serve as crucial building blocks, aiding in the intrinsic formation of essential skin proteins like collagen and elastin. These oligopeptides can specifically engage fibroblast receptors, stimulating the natural synthesis of new collagen, elastin, and hyaluronic acid within the skin. This action contributes directly to improved skin moisture, elasticity, and a visible reduction in the appearance of dryness or flaking. The strategic lauroyl modification, a fatty acyl group, is engineered to augment its interaction with the skin and its lipid barrier, potentially imparting emollient characteristics or acting as a mild surfactant.

Synergies

  • May benefit from co-formulation with other biopolymers for enhanced film-forming capabilities.

Conflicts

  • Avoid co-formulation with nitrosating systems.
  • Raw material must maintain a minimum purity of 99%.
  • Raw material should not exceed 0.5% secondary amine content.
  • Final product must have a maximum nitrosamine content of 50 µg/kg.
  • Requires storage in nitrite-free containers to prevent undesirable reactions.
