C11-15 PARETH-40

Description

C11-15 Pareth-40 is a synthetic nonionic surfactant and emulsifier widely used in skincare and cosmetic formulations. This ethoxylated fatty alcohol is derived from petrochemical sources and is characterized by its ability to reduce surface tension between oil and water phases.

The ingredient's name indicates its chemical structure: C11-15 refers to the carbon chain length of the fatty alcohol component, while Pareth-40 signifies that it has been ethoxylated with approximately 40 moles of ethylene oxide. This structure grants C11-15 Pareth-40 excellent solubilizing properties, making it effective in creating stable emulsions and microemulsions.

In skincare products, C11-15 Pareth-40 functions as an emulsifier, helping to blend oil and water-based ingredients. It also acts as a surfactant, assisting in the removal of dirt and oil from the skin. The ingredient is known for its mildness and low irritation potential, making it suitable for use in a variety of formulations, including cleansers, lotions, and creams.

C11-15 Pareth-40 is particularly valued for its ability to enhance the spreadability of products and improve their overall texture and feel on the skin. It can also aid in the solubilization of fragrances and other oil-soluble ingredients in water-based formulations.
