PEG-55 Propylene Glycol Oleate is a high-EO (55 moles ethylene oxide) non-ionic surfactant and emulsifier derived from oleic acid, propylene glycol, and polyethylene glycol. It is a clear to pale yellow viscous liquid that excels at solubilizing fragrances, essential oils, and lipophilic actives in aqueous systems while providing mild cleansing and emolliency. This ingredient is particularly valued in clear, transparent formulations (micellar waters, toners, shampoos, body washes, makeup removers) for its excellent clarity, low cloud point, and ability to create stable, oil-free systems without residue or greasiness.

What is PEG-55 PROPYLENE GLYCOL OLEATE used for?
- Fragrance / Oil solubilizing: Dissolves large amounts of perfumes, essential oils, and lipophilic ingredients in water-based products. Frequently used in clear shampoos, body washes, toners, and micellar waters for transparent, non-cloudy formulations.
- Emulsifying / Co-emulsifier: Stabilizes light O/W emulsions and improves texture. Ideal for fluid cleansers, makeup removers, and lightweight lotions requiring clarity and stability.
- Surfactant / Mild cleansing: Provides gentle cleansing with low irritation and good rinsability. Common in facial cleansers, baby products, and sensitive-skin washes for effective yet non-stripping removal of makeup and impurities.
Origin
PEG-55 Propylene Glycol Oleate is produced by esterification of oleic acid (from vegetable oils like olive or high-oleic sunflower) with propylene glycol. It is followed by ethoxylation with 55 moles of ethylene oxide. The oleic base is renewable, while the PEG chain is petrochemical-derived. It is supplied as a high-active viscous liquid (often 90-100%) and is biodegradable, making it suitable for many clean and eco-conscious formulations.

CLEANSINGSafety Profile
PEG-55 Propylene Glycol Oleate is considered safe for cosmetic use per CIR Expert Panel assessments of PEG esters and ethoxylated glycerides (safe as used when properly purified). It has a low to moderate hazard rating from EWG (typically 1-3) due to potential 1,4-dioxane and ethylene oxide residuals from ethoxylation (minimized in cosmetic grades). It is significantly milder than sulfates, with very low eye/skin irritation potential at typical concentrations (0.5-10%). Well-tolerated across skin types, including sensitive.
