What Is Isopropyl palmitate?

Isopropyl palmitate is a colorless and almost odorless liquid substance made from palm oil and/or animal fats. Palm oil typically comes from palm trees, which are native to western Africa but grow throughout tropical areas around the world.[1,2] Their seeds produce the oil.[3] Isopropyl palmitate is used in hundreds of personal care and cosmetic products, including sunscreen, deodorant, perfumes, and other items.[4,5]

What Does Isopropyl palmitate Do in Products?

Puracy does not use this in any of our products. Isopropyl palmitate acts as a moisturizer in some products by helping bind moisture to the skin. It is also an emollient, which helps products spread smoothly, and it can be used as a fragrance ingredient.[6] It dissolves in oil but not in water.[7]

How Isopropyl palmitate Is Made

Isopropyl palmitate is produced by transesterification of methyl ester with isopropyl alcohol. The process includes the removal of methanol by distillation or esterification of the fatty acid with isopropyl alcohol.[8,9] Isopropyl palmitate is a cetyl ester, which is the International Nomenclature Cosmetic Ingredient (INCI) name for a wax composed of a mixture of esters of saturated fatty acids and fatty alcohols. Cetyl esters is a constituent of a broader group of cosmetic ingredients, the alkyl esters, which consist of the reaction products of fatty acids and alcohols.[10]
