What Is Hydrolyzed Jojoba Protein?
Hydrolyzed jojoba protein is the protein fraction of seeds from the jojoba plant (Simmondsia chinensis) that has been hydrolyzed. Hydrolysis is a chemical process involving the reaction of a substance with water to form a modified substance.
Much like the oil also extracted from this plant, hydrolyzed jojoba protein is primarily used in cosmetics as a hydrating and conditioning ingredient in both skin care and hair care products. Its moisturizing properties can provide a temporary improvement in the appearance of fine lines and wrinkles (as most moisturizing ingredients do).
The independent Cosmetics Ingredient Council has ruled hydrolyzed jojoba protein safe in its current usage in cosmetics. The typical use level of hydrolyzed jojoba protein in leave-on cosmetics is 0.001-0.025%.
