ISOBUTYL STEARATE

Description

Isobutyl stearate is a versatile ester compound widely used in cosmetic and personal care formulations. This colorless, odorless liquid is derived from the esterification of isobutyl alcohol and stearic acid. Its molecular structure consists of a long, straight-chain fatty acid component combined with a branched alcohol, resulting in unique properties beneficial for skincare applications.

As an emollient, isobutyl stearate provides a smooth, silky feel to the skin without leaving a greasy residue. It effectively enhances the spreadability of formulations, improving product texture and application. The ingredient exhibits excellent stability and compatibility with a wide range of cosmetic ingredients, making it suitable for various product types.

Isobutyl stearate functions as an effective skin conditioning agent, helping to maintain skin softness and suppleness. It also acts as a mild occlusive, forming a protective barrier on the skin's surface to reduce transepidermal water loss. This property contributes to improved skin hydration and moisture retention.

In skincare formulations, isobutyl stearate is commonly used in concentrations ranging from 1% to 10%, depending on the desired effect and product type. It is particularly valuable in anhydrous formulations, such as lip balms, sunscreens, and oil-based serums.
