Valuable CAS 103819-45-0 / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

MINK OIL PEG-13 ESTERS is a versatile conditioning agent for both skin and hair. It functions as an emollient, helping to enhance the skin's natural barrier and maintain hydration levels. Additionally, it serves as a surfactant and emulsifier, stabilizing product formulations.

Science

Mechanism of Action

As a skin conditioning agent and emollient, MINK OIL PEG-13 ESTERS provides the skin with exogenous lipids, which integrate into the skin barrier. This action improves hydration, reduces transepidermal water loss, and contributes to a smoother, softer skin texture, while also offering protection against inflammation. Its surfactant properties reduce the interfacial tension between oil and water, and as an emulsifying agent, it significantly improves the stability and consistency of cosmetic emulsions.

Stability

Polyethylene glycols (PEGs) are generally well tolerated by the skin and exhibit resistance to microbiological degradation, often negating the need for additional preservatives. As an emulsifying agent, this ingredient is noted for improving the overall stability of emulsions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed MINK OIL PEG-13 ESTERS, within the broader category of 130 PEGylated oils, safe for use in cosmetics under current practices and concentrations, provided formulations are non-irritating. While there are theoretical concerns regarding residual ethylene oxide and 1,4-dioxane from the ethoxylation process, which are considered potential carcinogens, the safety is dependent on the purity of the final product. No specific maximum concentration for MINK OIL PEG-13 ESTERS was specified; however, for other PEGylated oils, safe concentrations up to 97% have been observed in rinse-off products. There is no specific SCCS or FDA status available for this exact ingredient.
