Hydrolyzed jojoba esters are essential fatty acids from the jojoba plant, broken down by water to form a new complex with properties different from the original source. An analogy to this process is the way humans digest food to convert it into energy.
Jojoba esters act as emollients in cosmetics. Research shows that these esters play a role in helping the skin retain moisture and improve its barrier function. When the pearl form of this ingredient is used, it can act as a gentle scrub for thoroughly cleansed skin. The hydrolyzed form can also improve oxidative stability of vulnerable antioxidants.
At room temperature, hydrolyzed jojoba esters are a sticky, viscous gel. The independent Cosmetic Ingredient Review Panel has found that jojoba oil and its esters (including hydrolysed jojoba esters) are safe when used in cosmetics. https://www.paulaschoice.com/ingredient-dictionary/ingredient-hydrolyzed-jojoba-esters.html?q=Hydrolyzed%20Jojoba%20Esters&fdid=ingredients
