What it is
Lauryl lactate is the ester formed from lactic acid and lauryl (dodecyl) alcohol. It is a lightweight, low-viscosity emollient that spreads easily and leaves a soft, silky, non-tacky finish. It is often used to improve the sensory feel of sunscreens and to help solubilize and carry other ingredients within the formula.
Safety & warnings
Lauryl lactate is generally well tolerated as a cosmetic emollient. As a fatty ester it can contribute to richness in oil-heavy formulas, which users prone to congestion may wish to consider. It is not a recognized fragrance allergen.
Origin & sourcing
Synthetic. It is made by esterifying lactic acid with lauryl alcohol; the lauryl alcohol is frequently derived from plant oils such as coconut or palm.
