SODIUM MYRISTOYL HYDROLYZED COLLAGEN.

Valuable / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

A sophisticated derivative of hydrolyzed collagen, Sodium Myristoyl Hydrolyzed Collagen acts as a multi-functional conditioning agent. It excels in drawing moisture into the skin while providing emollient properties, contributing to a smoother, more hydrated complexion. Beyond surface benefits, its smaller peptide components may support the skin's natural collagen and elastin production.

Antistatic Hair Conditioning Skin Conditioning Cleansing Agent Humectant Emollient

Science

Mechanism of Action

This ingredient functions primarily as a humectant and emollient, attracting and retaining water within the stratum corneum to enhance skin hydration and texture. As a hydrolyzed collagen derivative, it delivers oligopeptides—small peptide fragments—that can penetrate the epidermis. Once in the dermis, these peptides serve as vital amino acid building blocks for synthesizing new collagen and elastin. Furthermore, they may actively stimulate fibroblast cells to increase the production of structural proteins like collagen and elastin, as well as hyaluronic acid, which is crucial for skin volume and hydration. Some evidence also suggests antioxidant capabilities.

Stability

Optimal stability and performance for hydrolyzed collagen derivatives are typically achieved within a pH range of 5.0-6.5. Formulators should be mindful of the ingredient's isoelectric point (pI), which generally falls between 3.68 and 5.7, and ideally avoid formulating products near this range to ensure optimal emulsification and emulsion stability.

Conflicts

  • When co-formulated with certain UV filters, such as octocrylene (with or without butyl methoxydibenzoylmethane and TiO2), hydrolyzed collagen has been observed to reduce the SPF values and overall photoprotective effectiveness of sunscreens. This interaction is a critical consideration in sunscreen product development.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of hydrolyzed collagen for cosmetic use, a conclusion reinforced in 2006. Regulatory bodies including the FDA (classifying gelatin, a source of collagen peptides, as safe) and the European Union's Cosmetics Regulation also permit its inclusion in cosmetic products. No significant irritation or sensitization risks were reported in the available data.
