UNDECYL ALCOHOL

Description

Undecyl alcohol, also known as 1-undecanol or hendecanol, is a fatty alcohol with the chemical formula C11H24O. This long-chain aliphatic alcohol is derived from natural sources or synthesized through petrochemical processes. In skincare formulations, undecyl alcohol primarily functions as an emollient, emulsifier, and thickening agent.

As an emollient, undecyl alcohol helps to soften and smooth the skin by forming a protective barrier that reduces moisture loss. This property makes it valuable in moisturizers and creams designed for dry or sensitive skin. Its emulsifying capabilities allow it to stabilize oil-in-water emulsions, ensuring uniform product consistency and preventing separation of ingredients.

Undecyl alcohol also exhibits mild antimicrobial properties, which can contribute to product preservation and skin health. Its low potential for irritation makes it suitable for use in various skincare formulations, including those intended for sensitive skin types. Additionally, this ingredient can enhance the spreadability of products and improve their overall texture.

When used in appropriate concentrations, undecyl alcohol is generally considered safe for topical application. However, as with any skincare ingredient, individual sensitivities may vary, and patch testing is recommended for those with known allergies or sensitivities.
