ARACHIDIC ACID

Description

Arachidic acid is a long-chain saturated fatty acid with the chemical formula C20H40O2. Found naturally in various plant oils, including peanut and corn oil, it plays a significant role in skincare formulations. This fatty acid contributes to the skin's barrier function by enhancing its lipid composition and promoting moisture retention.

As an emollient, arachidic acid helps to soften and smooth the skin's surface, reducing roughness and improving overall texture. It demonstrates occlusive properties, forming a protective layer on the skin that prevents transepidermal water loss. This action is particularly beneficial for individuals with dry or sensitive skin conditions.

In skincare products, arachidic acid is often used in combination with other fatty acids to create stable emulsions and improve product consistency. It exhibits a high melting point, which can contribute to the structural integrity of formulations. Additionally, arachidic acid has been shown to have mild anti-inflammatory properties, potentially aiding in soothing irritated skin.

While generally well-tolerated, individuals with nut allergies should exercise caution when using products containing arachidic acid derived from peanut oil. As with any skincare ingredient, patch testing is recommended to ensure compatibility with individual skin types.
