C20-40 ACID

Description

C20-40 Acid, also known as Arachidyl Glucoside, is a long-chain fatty acid derivative that serves multiple functions in skincare formulations. This ingredient is primarily used as an emollient, emulsifier, and surfactant, contributing to the texture, stability, and performance of various cosmetic products.

Derived from natural sources such as coconut or palm oil, C20-40 Acid is composed of a mixture of fatty acids with carbon chain lengths ranging from 20 to 40. Its molecular structure allows it to form a protective barrier on the skin's surface, helping to reduce transepidermal water loss and improve skin hydration.

As an emulsifier, C20-40 Acid helps blend oil and water-based ingredients, creating stable and smooth formulations. Its emollient properties provide a silky, non-greasy feel to skincare products, enhancing their sensory appeal. Additionally, this ingredient can act as a mild surfactant, assisting in the gentle cleansing of the skin without causing excessive dryness.

C20-40 Acid is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations. It is often found in moisturizers, serums, and cleansers, particularly those designed for dry or sensitive skin.
