ISOSTEAROYL HYDROLYZED COLLAGEN.

Valuable CAS 111174-63-1 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

Isostearoyl Hydrolyzed Collagen is a sophisticated collagen derivative engineered to bolster skin hydration and fortify its natural architecture. Through its humectant properties and supply of crucial amino acid building blocks, it aims to enhance dermal elasticity and firmness, thereby mitigating visible signs of aging.

Science

Mechanism of Action

This ingredient functions primarily as a hydroscopic agent, leveraging its inherent water-binding capacity to deeply hydrate the stratum corneum. As a hydrolyzed collagen derivative, it provides a spectrum of free amino acids essential for the biosynthesis of new collagen and elastin fibers. Furthermore, its constituent oligopeptides may act as ligands, potentially engaging with fibroblast receptors to stimulate the endogenous production of collagen, elastin, and hyaluronic acid. This multifaceted action supports the skin's intrinsic repair processes, contributing to improved elasticity, enhanced firmness, and a reduction in the appearance of fine lines and wrinkles for a refined and rejuvenated complexion.

Stability

Isostearoyl Hydrolyzed Collagen demonstrates high solubility in both cold and hot water. Post-hydrolysis, its isoelectric point typically shifts to a range between 3.68 and 5.7. It does not independently form films and generally requires co-formulation with other biopolymers for such applications.

Conflicts

  • Nitrosating systems (for related derivatives like Cocoyl Hydrolyzed Collagen, due to potential nitrosamine formation)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Hydrolyzed Collagen is safe for use in cosmetics. While a maximum concentration is not specified for Isostearoyl Hydrolyzed Collagen, related derivatives such as Cocoyl Hydrolyzed Collagen are subject to restrictions including avoidance of nitrosating systems, a minimum purity of 99%, a maximum secondary amine content of 0.5% in raw materials, a maximum nitrosamine content of 50 µg/kg, and storage in nitrite-free containers. The European Union's Cosmetics Regulation permits the use of hydrolyzed collagen. Topical applications of hydrolyzed collagen in FDA 510(k) cleared wound gels have been assessed as non-irritant and non-sensitizing.
