NONYL NONOXYNOL-49

Description

Nonyl Nonoxynol-49 is a synthetic surfactant and emulsifier commonly used in cosmetic and personal care formulations. This non-ionic compound belongs to the ethoxylated alkylphenol family and is characterized by its ability to reduce surface tension between oil and water phases. With a molecular structure consisting of a nonylphenol core and an average of 49 ethylene oxide units, Nonyl Nonoxynol-49 exhibits excellent solubilizing properties.

In skincare and cosmetic products, Nonyl Nonoxynol-49 functions primarily as an emulsifier, helping to create stable emulsions by dispersing and suspending oil-based ingredients in water-based formulations. It also acts as a mild cleansing agent and can enhance the spreadability of products. The ingredient is particularly useful in creating clear gel formulations and in solubilizing fragrances and essential oils.

While effective in its role, Nonyl Nonoxynol-49 has faced scrutiny due to environmental concerns related to its biodegradability and potential hormonal effects. As a result, many formulators are seeking alternative ingredients with similar functional properties but improved environmental profiles. When used in cosmetic formulations, it is typically incorporated at concentrations ranging from 0.1% to 5%, depending on the specific product requirements and regulatory guidelines.
