Description
Isopropyl palmitate (IPP) is a synthetic ester produced by reacting isopropyl alcohol with palmitic acid. It carries no E-code designation and is commercially available under trade names including Isopal, Deltyl, Propal, Emcol IP, and Kessco IPP. It is registered under CAS 142-91-6 and EC 205-571-1.
In personal care formulations, IPP functions as an emollient and skin-conditioning agent by forming a non-greasy occlusive layer that reduces transepidermal water loss without a heavy after-feel. In metalworking lubricants, it acts as a base carrier fluid, reducing friction between metal surfaces while improving the spreadability of active additives. Pharmaceutical manufacturers use it as a penetration-enhancing carrier in topical preparations.
IPP is supplied in cosmetic and pharmaceutical grades, with material conforming to Ph.Eur. and USP-NF monographs available on request. The substance is fully REACH-registered and classified under HS code 29157090. Standard packaging includes drums and IBC containers, with bulk quantities available subject to confirmation.
