TRIDECYL ALCOHOL.

Valuable CAS 112-70-9 / EMULSION STABILISING, FRAGRANCE, REFATTING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

Tridecyl alcohol is a long-chain fatty alcohol that functions primarily as a skin conditioning agent and emollient. It works to soften and smooth the skin by enhancing its lipid barrier and forming a protective film, thereby aiding moisture retention and shielding against external irritants.

Emollient Emulsion stabilising Masking Refatting Skin conditioning Viscosity controlling

Science

Mechanism of Action

This fatty alcohol operates by fortifying the skin's natural lipid barrier, creating a thin occlusive film on the skin's surface. This film not only prevents transepidermal water loss, thus helping the skin retain essential moisture, but also offers a physical defense against environmental stressors. Beyond its conditioning role, tridecyl alcohol contributes to product aesthetics through its refatting, emulsion stabilizing, and viscosity controlling properties.

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

While a specific CIR report for Tridecyl Alcohol is not available, the CIR Expert Panel has evaluated similar long-chain fatty alcohols as safe for cosmetic applications. Data from EWG, SkinSAFE, and INCI Beauty indicate a generally low risk for concerns like cancer, allergies, and immunotoxicity at typical cosmetic concentrations. However, GHS labeling for the pure substance suggests potential for skin and eye irritation, which is significantly mitigated in formulated products.
