C9-11 PARETH-6 CARBOXYLIC ACID

Description

C9-11 Pareth-6 Carboxylic Acid is a synthetic surfactant and emulsifying agent commonly used in skincare and personal care products. This ingredient is derived from ethoxylated fatty alcohols with a carbon chain length ranging from 9 to 11, combined with 6 moles of ethylene oxide and a carboxylic acid group. Its primary function is to reduce surface tension between oil and water, allowing these typically incompatible substances to mix and form stable emulsions.

In skincare formulations, C9-11 Pareth-6 Carboxylic Acid acts as an effective cleansing agent, helping to remove dirt, oil, and other impurities from the skin. It also aids in the even distribution of other active ingredients throughout the product. This compound is mild and generally well-tolerated by most skin types, making it suitable for use in a variety of skincare products, including cleansers, moisturizers, and serums.

The ingredient demonstrates good biodegradability and low potential for bioaccumulation, addressing environmental concerns associated with some surfactants. Its ability to function effectively in both acidic and alkaline conditions adds to its versatility in formulations. While generally considered safe for use in cosmetics, as with any ingredient, some individuals may experience sensitivity or allergic reactions.
