What it is
Isoamyl Laurate is a branched-chain ester formed from isoamyl alcohol and lauric acid, used as an emollient and spreading agent. It has a notably light, dry, non-greasy slip, which makes it popular as a natural-derived alternative to volatile silicones and light synthetic esters in mineral sunscreens and facial formulas. It can also help disperse and wet pigments and mineral UV filters, improving spreadability.
Safety & warnings
Generally well tolerated and considered non-sensitizing in cosmetic use. It is not a fragrance allergen. As a light branched ester it is generally regarded as low on the comedogenicity scale, though as with any emollient, very acne-prone users may prefer to patch test.
Origin & sourcing
Can be synthesized from plant-derived feedstocks; the lauric acid portion is commonly sourced from coconut or palm, making it a frequent choice in naturally-derived and clean-positioned formulas.
Questions everyone asks
Why is isoamyl laurate used in mineral sunscreens?
Its light, dry slip helps spread the formula and disperse mineral filters smoothly while keeping the finish non-greasy.
Is isoamyl laurate a silicone?
No. It is a plant-derivable ester often chosen as a natural-feeling alternative to volatile silicones for a similar light, dry texture.
