Isostearyl neopentanoate

Isostearyl neopentanoate (CAS 58958-60-4), also known as isostearyl pivalate or isooctadecyl pivalate, is a branched-chain ester used as an emollient, plasticizer, and carrier in personal care and industrial formulations.

Its low viscosity and excellent spreadability make it a preferred ingredient where skin feel, lubricity, and ingredient compatibility drive formulation decisions. In color cosmetics and skincare, it functions as an emollient.

It serves as a pigment-dispersing agent in foundations, lipsticks, and sunscreens, improving texture and wear. It acts as a carrier solvent for active ingredients in leave-on formulations such as serums and body oils.

This material is ideal where clean skin feel without greasiness is a priority. In hair care, it is used to enhance gloss and manageability in conditioning treatments and styling products.

Industrial lubricant formulators use it as a base fluid or additive where a branched ester with good thermal stability and low pour point is required. It is supplied as a clear, low-viscosity liquid.

It is available in cosmetic-grade quality meeting standard personal care industry specifications, and in technical grade for industrial lubricant applications. Bulk supply is standard in drums and IBCs.

Smaller packaging is available for development and sampling purposes. This versatile ester provides consistent performance across a wide range of chemical and personal care applications.
