Glyceryl Ricinoleate God Emollient Fugt Glyceryl Ricinoleate at a glance Synthetic and/or plant-derived blend of glycerin and castor oil derivative Has emollient, emulsifying and cleansing properties Excellent for preventing moisture loss Considered safe as used in cosmetics Glyceryl Ricinoleate description Glyceryl ricinoleate is a single ester (monoester) made from combining glycerin with ricinoleic acid, a fatty acid derived from castor seed oil. Although the latter part if plant-based, the source of glycerin may be synthetic, hence this ingredient is a hybrid. Of note, some suppliers offer an all-natural version, with the glycerin being vegetable-derived. It’s a versatile ingredient due to its emollient, emulsifying, and surfactant (cleansing) properties. As an emollient, its protectant properties help skin maintain surface hydration and can also add a wetter feel to moisturizers that may not otherwise feel as…well, moist. Use levels of glyceryl ricinoleate in cosmetics depend on its intended function. Amounts of 5–20% are common, with levels varying based on co-emulsifiers and partner emollients. The Cosmetic Ingredient Review Board has examined the data of glyceryl ricinoleate and considers it safe in current practices of use. Related ingredients: Glycerin
