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.
