10-UNDECENYL ACETATE

Description

10-Undecenyl acetate is a versatile synthetic ester widely used in skincare and cosmetic formulations. This clear, colorless liquid is derived from undecylenic acid, a fatty acid with antimicrobial properties. Its molecular structure consists of a long carbon chain with a terminal double bond and an acetate group, providing unique functional properties.

In skincare applications, 10-undecenyl acetate serves as an emollient and skin conditioning agent. It helps to soften and smooth the skin's surface, improving texture and reducing roughness. The ingredient also acts as a mild lubricant, enhancing the spreadability of formulations and contributing to a silky skin feel.

One of the key benefits of 10-undecenyl acetate is its ability to function as a fixative in fragrances, helping to prolong the scent of skincare products. Additionally, it exhibits antifungal properties, making it useful in formulations designed to address fungal-related skin issues.

When incorporated into skincare products, 10-undecenyl acetate is typically used at concentrations ranging from 0.1% to 5%. It is generally well-tolerated by most skin types and is compatible with a wide range of cosmetic ingredients, making it a valuable component in various skincare formulations.
