Overview
Myristyl myristate (CAS 3234-85-3 ), also known as tetradecyl tetradecanoate, is a saturated fatty acid ester derived from myristic acid and myristyl alcohol. It functions as an emollient, texture modifier, and carrier in personal care and pharmaceutical formulations.
This versatile ingredient contributes a dry, non-greasy skin feel that distinguishes it from heavier ester alternatives. In skin and body care products, including lotions and creams, it improves spreadability and delivers a smooth, velvety after-feel.
Color cosmetics manufacturers use it as a binder and texture agent in lipsticks, foundations, and eyeshadow compacts. In these applications, it helps control hardness and pigment dispersion while ensuring a consistent application for the end user.
Solid and semi-solid pharmaceutical topical formulations incorporate it as a carrier to adjust consistency and support active ingredient delivery. It also appears in hair care products such as conditioners and styling waxes to aid slip.
The material is supplied as a white to off-white waxy solid or flake. It is available in cosmetic-grade and pharmaceutical-grade specifications, with the latter meeting USP or Ph.Eur. standards where required by the manufacturer.
Packaging typically ranges from kilogram-scale bags to bulk pallet quantities to suit both development and commercial production volumes. This ensures flexibility for companies operating at various stages of the product lifecycle.
