What Is Heptyl Undecylenate?
Heptyl undecylenate is a castor oil-derived natural skin care ingredient that can help hydrate skin, prevent moisture loss and improve the feel of formulas by reducing the likelihood of a greasy after-feel.\n\nAs a lightweight emollient, heptyl undecylenate lends skin a protective “shield,” trapping moisture to further prevent trans epidermal water loss (TEWL) and hydrate. Through this, heptyl undecylenate gives skin a smooth, moisturized look. It’s often used as an alternative to mineral oil or silicone.\n\nUnlike other emollients, this derivative (known as an ester) leaves a powdery, light feel on skin, not a greasy, oil one. It’s used in formulas to help mitigate the greasy feel that other hydrating emollient ingredients leave on skin.\n\nHeptyl undecylenate also serves as a solubilizer for organic sunscreen filters.\n\nThe Cosmetic Ingredient Review Expert Panel concluded that heptyl undecylenate is safe for use in cosmetics, appearing in formulas at amounts ranging from 0.01% to 26%.
