PEG-75 MEADOWFOAM OIL.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-75 Meadowfoam Oil is a polyoxyethylenated derivative of meadowfoam seed oil, functioning as a multi-tasking ingredient that enhances skin hydration and product texture. It acts as an emollient, preventing transepidermal water loss, while also serving as a mild cleansing and emulsifying agent for stable formulations.

Science

Mechanism of Action

This ingredient primarily functions as an emollient, contributing to softer and smoother skin. It establishes a breathable yet effective barrier on the skin's surface, thereby minimizing transepidermal water loss and preserving moisture. Derived from meadowfoam seed oil, its fatty acid profile closely resembles the skin's natural sebum, assisting in the regulation of oil balance. Additionally, it provides antioxidant protection against environmental stressors due to its natural tocopherol content. In formulations, it reduces surface tension, acting as a surfactant and emulsifier to facilitate the blending of immiscible liquids and enhance foam generation and cleansing properties. It also serves as a solubilizer for hydrophobic compounds in aqueous solutions.

Stability

Meadowfoam Seed Oil, the base oil, exhibits exceptional thermal stability, known as one of the most resilient lipids, which can contribute to the stability of other oils in a blend. Polyethylene glycols and their derivatives are generally well-tolerated by the skin and are not prone to microbiological degradation, often negating the need for additional preservatives in the formulation.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) panel deemed PEG-75 Meadowfoam Oil safe for cosmetic use under the condition that formulations are non-irritating. A study on PEG-75 (a component) indicated it was not a sensitizer. Broader assessments of PEGylated oils support this safety profile when used in current practices and concentrations, provided they are non-irritating. The Expert Panel advises against using cosmetic formulations containing PEGs on compromised or damaged skin. Potential concerns include impurities like ethylene oxide and 1,4-dioxane, along with possible pesticide residues or heavy metals, which manufacturers are expected to eliminate through rigorous purification processes. While the FDA lists PEG-75 as Generally Recognized As Safe (GRAS) for food applications, this status does not directly extend to cosmetic use.
