STEARTRIMONIUM HYDROXYETHYL HYDROLYZED COLLAGEN.

Valuable / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING

STEARTRIMONIUM HYDROXYETHYL HYDROLYZED COLLAGEN is a complex conditioning agent engineered for both skin and hair. It integrates the robust hydrating and elasticity-supporting attributes of hydrolyzed collagen with the surface-smoothing and static-reducing effects from its steartrimonium moiety.

Antistatic Emollient Film forming Hair conditioning Humectant Skin conditioning

Science

Mechanism of Action

This ingredient operates by leveraging its hydrolyzed collagen component, which functions as a hydrophilic agent, actively attracting and retaining moisture within the skin. This action effectively augments dermal hydration, restores suppleness, and diminishes the appearance of flaking. Concurrently, it aids in preserving the skin's natural elasticity and overall health. The steartrimonium portion concurrently provides pronounced conditioning and antistatic properties.

Stability

Hydrolyzed collagen exhibits optimal stability and functionality within a pH range of 5.0 to 6.5. Its isoelectric point typically falls between 3.68 and 5.7, a range distinct from native collagen, influencing its solubility and activity based on the degree of hydrolysis.

Conflicts

  • Cannot form films by itself and requires co-formulation with other biopolymers for film-forming applications.

Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly evaluated and concluded that Hydrolyzed Collagen is safe for cosmetic applications, a finding reaffirmed in 2006. Clinical studies on hydrolyzed collagen demonstrated no instances of skin sensitivity, phototoxicity, or irritation. However, a documented case of contact urticaria in a 22-year-old female was linked to a hair conditioner containing 'steartrimonium hydrolyzed animal protein,' indicating a potential for specific allergic responses, possibly attributable to the 'steartrimonium' component. Regulatory guidelines within the European Union permit the inclusion of hydrolyzed collagen in cosmetic products, and EWG Skin Deep assesses STEARTRIMONIUM HYDROXYETHYL HYDROLYZED COLLAGEN with minimal concerns across various toxicity categories.

Verdict

Valuable

STEARTRIMONIUM HYDROXYETHYL HYDROLYZED COLLAGEN is a valuable ingredient for enhancing skin hydration and elasticity, alongside comprehensive hair conditioning benefits, with a generally favorable safety profile, though individual sensitivities to the 'steartrimonium' component should be considered.
