Science
Mechanism of Action
This ingredient primarily operates by enhancing the solubility of oil-soluble substances and fragrances within aqueous systems, acting as a lubricant to improve product feel, and stabilizing emulsions. As a humectant, it attracts and retains water in the stratum corneum, forming hydrogen bonds with water molecules and mitigating transepidermal water loss, which is particularly beneficial for restoring barrier function in dry skin. Its emulsifying properties ensure homogeneous mixing of oil and water phases, leading to consistent product texture and even distribution of active compounds.

Stability
Related polyethylene glycol derivatives exhibit excellent thermal and chemical stability, making them robust for diverse cosmetic applications. PEGs are valued for their broad range of viscosity and solubility profiles. Solid PEGs can also function as consistency enhancers and humectants, and their inherent microbiological stability often negates the need for additional preservatives.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed various PEGs and their derivatives, including related PEG-20 compounds, safe for cosmetic use at concentrations up to 11% when formulated to be non-irritating. High molecular weight PEGs, such as PEG-20 Glyceryl Triisostearate (>1,000 g/mol), are considered non-irritating and safe for use even in the eye area due to their limited skin penetration. While generally safe and non-sensitizing to normal skin, PEGs can be absorbed through compromised skin, which has been associated with contact dermatitis and systemic toxicity in severe burn patients. Concerns regarding potential contamination with toxic impurities like ethylene oxide and 1,4-dioxane have been noted by the EWG Skin Deep database. Conversely, the FDA has approved PEG-20 for specific food applications, and related compounds like PEG-20 Hydrogenated Castor Oil are rarely reported to cause irritation or allergic reactions.
