Nonyl Nonoxynol-11 Phosphate, also known by its more technical name Poly(oxy-1,2-ethanediyl), .alpha.-(dinonylphenyl)-.omega.-hydroxy-, phosphate (11 mol EO average molar ratio), is a synthetic compound primarily used in cosmetic products for its cleansing properties. This ingredient is part of a larger family of compounds known as nonoxynols, which are nonionic surfactants. Surfactants are substances that help to reduce the surface tension of liquids, making them more effective at spreading and mixing with other substances.
The history of Nonyl Nonoxynol-11 Phosphate in cosmetics dates back to the mid-20th century when the demand for more effective and versatile cleansing agents began to rise. As the cosmetic industry evolved, so did the need for ingredients that could deliver superior performance without compromising safety. Nonyl Nonoxynol-11 Phosphate emerged as a reliable option due to its ability to effectively break down oils and dirt, making it a popular choice in various skincare and haircare formulations.
The production of Nonyl Nonoxynol-11 Phosphate involves a multi-step chemical process. It starts with the ethoxylation of nonylphenol, which means adding ethylene oxide molecules to nonylphenol to create a series of compounds known as nonylphenol ethoxylates. Specifically, for Nonyl Nonoxynol-11, an average of 11 ethylene oxide units are added. This intermediate product is then reacted with phosphoric acid to produce the final phosphate ester. The result is a compound that is both hydrophilic (water-attracting) and lipophilic (oil-attracting), making it highly effective at emulsifying and removing impurities from the skin and hair.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Nonyl Nonoxynol-11 Phosphate:
Nonyl Nonoxynol-11 Phosphate is primarily used for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin. When included in cosmetic formulations, it acts as a surfactant, which lowers the surface tension between ingredients, allowing them to mix better and effectively cleanse the skin. This makes it a valuable ingredient in products like facial cleansers, body washes, and shampoos, ensuring that your skin and hair are left feeling clean and refreshed.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Nonyl Nonoxynol-11 Phosphate is generally considered safe for use in cosmetic products, but like any ingredient, it may not be suitable for everyone. Its allergenic potential is relatively low, but individual reactions can vary.
Potential side effects of topical application of this ingredient include:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Nonyl Nonoxynol-11 Phosphate during pregnancy are lacking. Therefore, it is advisable to consult a healthcare professional for further advice.
Adverse reactions to Nonyl Nonoxynol-11 Phosphate are not very common, but they can occur. It is recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, Nonyl Nonoxynol-11 Phosphate scores a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means it has a low likelihood of clogging pores, making it generally suitable for people prone to acne, blemishes, or breakouts. However, individual reactions can vary, so monitoring your skin’s response is essential.
