STEARYL STEAROYL STEARATE.

Insufficient Data CAS 54684-78-5 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

Stearyl Stearoyl Stearate is a complex ester primarily valued for its conditioning properties in skincare. While extensive specific data for this exact ingredient is limited in the provided research, it is structurally related to other fatty esters known to enhance skin feel and product texture.

Science

Mechanism of Action

While a precise mechanism for Stearyl Stearoyl Stearate is not explicitly detailed in the provided data, related fatty esters, such as Stearyl Stearate, function as emollients. They operate by filling the microscopic spaces between dead skin cells, which visibly softens and smooths the skin. Additionally, these esters form a lightweight, breathable film on the skin's surface, acting as a barrier to seal in moisture and reduce transepidermal water loss. They also contribute to product aesthetics by acting as skin-conditioning and viscosity-controlling agents.

Key findings

  1. 01 The CIR Expert Panel (2017) conducted a safety assessment on Stearyl Stearate and structurally related esters. This assessment found no evidence of irritation, sensitization, or comedogenicity at use concentrations. It also established the safety of Stearyl Stearate for cosmetic use at concentrations up to 49.3% (as reported in eye lotions/makeup).

Stability

Specific formulation stability data for Stearyl Stearoyl Stearate is not available in the provided research. However, related fatty esters like Stearyl Stearate are known to be chemically stable but are susceptible to hydrolysis when exposed to strong acid or strong alkali conditions. They are typically insoluble in water and soluble in oil.

Unknown
Sensitization risk Low

The CIR Expert Panel concluded that Stearyl Stearate is safe for cosmetic use, with maximum reported concentrations up to 49.3%. Clinical data for Stearyl Stearate and related esters showed no evidence of irritation, sensitization, or comedogenicity. However, the provided research explicitly notes that specific SCCS or FDA regulatory status for Stearyl Stearoyl Stearate itself was not found, though its components, such as stearic acid, are generally recognized as safe (GRAS) by the FDA.
