What It Does PEG-40 Hydrogenated Castor Oil helps disperse oils, fragrances, essential oils, and lipophilic ingredients into aqueous systems. It improves clarity, reduces separation, and supports more stable cosmetic formulations with better sensory performance. Typical Use Levels 0.5–3% — Light solubilizing and fragrance incorporation 3–10% — Cleansing systems and micellar applications 10%+ — Higher oil-load or specialized surfactant systems How to Incorporate Pre-mix with fragrance oils or essential oils before adding to water. Can be added directly into the water phase of formulations. Compatible with many surfactants, glycols, and humectants. Formulation Notes Helps improve clarity in water-based systems. Useful for incorporating fragrance oils into mists and sprays. Can improve cleansing performance and reduce harshness in some systems. Widely used in micellar waters, toners, shampoos, and body cleansers. Works well alongside other nonionic surfactants and solubilizers. Common Applications Facial cleansers and micellar waters Body washes and shampoos Fragrance and essential oil sprays Toners and water-based serums Bath and cleansing products Useful when formulators need oil and water to cooperate temporarily instead of behaving like divorced parents at a school recital.
