ISONONYL ALCOHOL

Description

Isononyl alcohol is a versatile synthetic ingredient commonly used in both skincare and haircare formulations. This colorless, oily liquid functions primarily as an emollient and solvent, contributing to the smooth texture and application of various products. With its branched-chain structure, isononyl alcohol offers excellent spreadability and a light, non-greasy feel on the skin and hair.

In skincare, isononyl alcohol helps to soften and condition the skin, improving its overall texture and appearance. It aids in the even distribution of other active ingredients and can enhance the penetration of certain compounds. In haircare, it acts as a conditioning agent, helping to smooth the hair cuticle and reduce frizz.

Isononyl alcohol is generally well-tolerated by most skin types and is considered low in irritation potential. It is often used in leave-on products such as lotions, creams, and hair serums. While it does not possess significant moisturizing properties on its own, it works synergistically with other ingredients to improve product performance and sensory attributes.
