SULFATED PEANUT OIL.

Questionable CAS 73138-79-1 / CLEANSING, FOAMING, SURFACTANT - CLEANSING

Sulfated Peanut Oil serves as a derivative of peanut oil, distinguished by its primary role as a multifunctional surfactant. It is precisely engineered to contribute cleansing, foaming, and emulsifying properties to skincare formulations.

Summary

surfactant emulsifier cleansing foaming

Science

Mechanism of Action

This ingredient operates predominantly as a surfactant, effectively lowering surface tension to allow for the removal of oil-soluble impurities and enhancing product lather. Beyond its cleansing capabilities, it acts as an emulsifier to maintain formulation stability and may also improve the dermal penetration of co-applied compounds.

Stability

While the base peanut oil is susceptible to oxidative rancidity and thickening with air exposure, necessitating storage below 40°C in airtight, light-resistant containers, sulfation may influence these properties. General stability principles for lipid derivatives should be observed.

The CIR Expert Panel concluded that this ingredient, along with related peanut derivatives, is safe for cosmetic use, provided stringent control over aflatoxin and protein levels. However, the SCCS identified a significant risk of peanut allergy induction, especially in young children. Consequently, EU Cosmetics Regulation mandates a maximum level of 0.5 ppm for peanut proteins in such derivatives, effective September 2018.
