Ethyl palmitate

CAS: 628-97-7

Overview

Ethyl palmitate (CAS 628-97-7 ), also identified under FEMA 2451 , is a fatty acid ethyl ester derived from palmitic acid used as an emollient, lubricant, and emulsifier across food, cosmetic, and industrial applications.

Its ester structure delivers skin-feel modification and surface lubrication without the heaviness of mineral-based alternatives. In personal care formulations, it functions as a lightweight emollient and spreading agent.

It is used in creams, lotions, and hair conditioners, improving texture and skin absorption. Food manufacturers use it as a flavoring ingredient and carrier at FEMA-approved levels in confectionery, baked goods, and beverage applications.

In lubricant and metalworking formulations, it acts as a base fluid or additive where biodegradable, ester-based lubrication is required. Cosmetic formulators also incorporate it as an emulsification aid in water-in-oil systems.

This material is particularly useful where controlled dispersion of active ingredients is a priority. It is supplied as a white to off-white waxy solid or pale liquid depending on temperature, typically in flake or molten bulk form.

Standard grades include food-grade ( FCC -compliant) and cosmetic-grade material meeting purity specifications suitable for regulated formulations. Technical grade is available for industrial and lubricant applications.

These industrial grades are used where food or cosmetic compliance is not required. The product offers versatile performance across multiple sectors, ensuring high-quality results in diverse manufacturing environments.
