PEG-20 ALMOND GLYCERIDES.

Valuable CAS 226993-90-4 / SURFACTANT - EMULSIFYING

This versatile ingredient functions primarily as a skin conditioning agent, notably enhancing skin hydration and reinforcing the skin barrier. It also serves as an effective surfactant and emulsifier, crucial for stabilizing cosmetic formulations and improving the solubility of various actives.

Science

Mechanism of Action

PEG-20 Almond Glycerides exerts its effects on the skin through several mechanisms. As an emollient, it provides external lipids, thereby filling intercellular gaps within the stratum corneum to optimize barrier function, enhance moisture retention, and reduce transepidermal water loss (TEWL). This action contributes to protection against inflammation and minimizes skin drying. Furthermore, it operates as a surfactant and emulsifier, effectively lowering the interfacial tension between immiscible liquid phases (oil and water) to facilitate the creation and stability of cosmetic emulsions. It also exhibits humectant properties, actively drawing moisture to the skin, and functions as a solubilizer for a range of components, including active ingredients, perfume oils, and colorants.

Stability

Polyethylene glycols (PEGs) and their derivatives, including PEG-20 Almond Glycerides, are generally stable and well-tolerated by the skin, exhibiting no particular microbiological sensitivity. However, products incorporating this ingredient must be meticulously formulated to ensure they are non-irritating.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed PEG-20 Almond Glycerides and related PEGylated alkyl glycerides, deeming them safe for use in cosmetics under current practices and concentrations, provided they are formulated to be non-irritating. A human repeat insult patch test conducted at 5% concentration indicated no sensitization potential. However, undiluted PEG-20 Almond Glycerides has demonstrated irritation to rabbit skin in primary irritation studies. The FDA lists this ingredient as safe for general or specific, limited use in food applications. Concerns regarding potential residues of ethylene oxide and 1,4-dioxane exist due to the ethoxylation manufacturing process, though these can be minimized through stringent purification to achieve high purity levels.
