PEG-35 Castor Oil is a polyethylene glycol derivative of castor oil (Ricinus communis), ethoxylated with an average of 35 moles of ethylene oxide. This non-ionic surfactant and emulsifier is valued for its ability to solubilize oils, fragrances, and lipophilic actives in aqueous systems while providing mild cleansing and emolliency. It appears as a clear to pale yellow, slightly viscous liquid and is widely used in shampoos, shower gels, facial cleansers, micellar waters, makeup removers, lotions, and decorative cosmetics for improved texture, stability, and uniform distribution.

What is PEG-35 CASTOR OIL used for?
- Emulsifying: Promotes stable oil-in-water emulsions and homogenizes oils/fats in water. Frequently used in creams, lotions, and cleansers for smooth, non-separating textures.
- Surfactant/Cleansing: Reduces surface tension for gentle removal of dirt, makeup, and impurities. Common in shampoos, body washes, micellar waters, and facial cleansers.
- Solubilizing: Dissolves fragrances, essential oils, and actives in aqueous formulations. Ideal for transparent toners, serums, and perfume bases.
Origin
PEG-35 Castor Oil is produced synthetically by ethoxylation of natural castor oil (derived from the seeds of Ricinus communis) with ethylene oxide. The controlled reaction adds approximately 35 moles of EO to create a water-soluble, non-ionic surfactant. It is petrochemical-derived in the ethoxylation step but leverages renewable castor oil as the base, yielding a consistent, high-purity liquid for cosmetic applications.

CLEANSINGSafety Profile
PEG-35 Castor Oil is considered safe for cosmetic use per the CIR Expert Panel assessment of PEG Castor Oils (safe up to 50% concentration in formulations). It has a low to moderate hazard rating from EWG (due to potential 1,4-dioxane contamination from ethoxylation, though minimized in purified grades). It shows low irritation and sensitization potential at typical levels (1-10%). Well-tolerated in rinse-off and leave-on products; avoid in highly sensitive or damaged skin if residuals are a concern. Approved by EU COSING for emulsifying and surfactant functions.
