Frequently Asked Questions

What is isopropyl palmitate used for?

Isopropyl palmitate (IPP, CAS 142-91-6) is the isopropyl ester of palmitic acid, used as an emollient and emulsifier in creams and lotions, as a plasticizer in formulated products, and as a spreading solvent/carrier. It also serves as a processing aid and component in metalworking fluids.

Is isopropyl palmitate from palm oil?

It is made by esterifying palmitic acid with isopropyl alcohol; the palmitic acid feedstock is often derived from palm oil but can come from other plant sources. The finished ester (C19H38O2) is a synthetic emollient. Feedstock sourcing details can be confirmed on request.

Is isopropyl palmitate natural or synthetic?

It is a synthetic ester produced by esterification, though its palmitic acid feedstock can be plant-derived. The resulting material is isopropyl palmitate, CAS 142-91-6. Lot identity is confirmed on the Certificate of Analysis.

What is the difference between isopropyl palmitate and palmitic acid?

Palmitic acid is a saturated C16 fatty acid with a free carboxylic acid group; isopropyl palmitate is its isopropyl ester. Esterification converts the solid, polar acid into a lighter, oilier emollient ester (C19H38O2) with a smoother skin-feel and different solubility.
