HYDROXYCETYL HYDROXYETHYLSTEARAMIDE.

Insufficient Data / SKIN CONDITIONING

Hydroxycetyl Hydroxyethylstearamide is a sophisticated fatty amide designed to enhance skin barrier function. Its unique chemical structure promotes superior emolliency, contributing to profound skin hydration and a visibly smoother texture. Additionally, it acts as a robust emulsion stabilizer, ensuring product integrity and consistent delivery.

Emollient Skin-conditioning agent Emulsion stabilizer

Science

Mechanism of Action

This ingredient functions by forming a non-occlusive, lubricating film on the skin's surface, leveraging its long hydrocarbon chains to reduce transepidermal water loss and provide intense moisturization. Its amphiphilic nature, with both oil-loving and water-loving components, enables it to effectively stabilize emulsions, preventing the separation of oil and water phases in cosmetic formulations. It thus delivers both direct skin benefits and formulation stability.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

While not reviewed by the Cosmetic Ingredient Review (CIR), the European Commission has established strict regulatory guidelines for Hydroxycetyl Hydroxyethylstearamide. The raw material must contain a maximum of 0.5% secondary amines, and the finished ingredient must achieve a minimum purity of 99%. Nitrosamine content in the ingredient must not exceed 50 microgram/kg, and products containing it must be stored in nitrite-free containers to prevent contamination. In the U.S., manufacturers are solely responsible for ensuring the safety of cosmetic ingredients before market entry.

Our Assessment

Verdict

Insufficient Data

While exhibiting promising emollient and skin-conditioning properties, the lack of specific clinical efficacy studies, unknown irritancy/comedogenicity, and the 'not reviewed' CIR status lead to an 'insufficient-data' rating, despite stringent European regulatory safeguards regarding nitrosamine formation.
