LANETH-10 ACETATE.

Valuable CAS 65071-98-9 / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Laneth-10 Acetate is a versatile lanolin-derived ingredient, functioning as a nonionic emulsifier and emollient. It is specifically designed to enhance skin and hair hydration, contributing to product stability and texture. Its unique structure, being both acetylated and ethoxylated, allows for broad cosmetic application.

Science

Mechanism of Action

This ingredient works by forming a stable interface between immiscible liquids like oil and water, acting as an effective emulsifier. As an emollient and skin conditioner, it forms a protective barrier on the skin's surface, reducing transepidermal water loss and imparting a smooth, soft feel. It also contributes to the structural integrity of cosmetic products by acting as a plasticizer, preventing brittleness and cracking.

Key findings

  1. 01 A facial mask containing 1% Laneth-10 Acetate demonstrated no primary irritation across 200 subjects after initial application. While 'fatiguing' skin changes were observed in 6% of volunteers after repeated applications (2-15), no skin sensitization occurred upon challenge, indicating low sensitizing potential.
  2. 02 In a separate study involving 50 human subjects, Laneth-10 Acetate was confirmed to be nonirritating and nonsensitizing.

Stability

Laneths and Laneth Acetates exhibit relative stability across typical cosmetic pH ranges. However, the presence of unsaturated components may lead to autoxidation or photolysis over extended shelf life. This oxidative degradation can be effectively mitigated by incorporating antioxidants such as butylated hydroxytoluene (BHT) or α-tocopherol into the formulation.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has consistently reaffirmed the safety of Laneth-10 Acetate for topical application, with the most recent evaluation in 2023. While specific maximum use concentrations for Laneth-10 Acetate were not explicitly reported, the broader Laneths and Laneth Acetates group is deemed safe in current cosmetic practices. Historical data for related lanolin-derived ingredients noted concentrations up to 40% in leave-on products and 10% in rinse-off products. It is important to note that ethoxylation, a part of its manufacturing, can lead to trace amounts of 1,4-dioxane, which should be controlled through stringent purification methods. The FDA regulates cosmetic product safety but does not pre-approve individual ingredients; no specific SCCS opinion was found for this ingredient.
