Nonyl Nonoxynol-10, also known as Poly(oxy-1,2-ethanediyl), .alpha.-(dinonylphenyl)-.omega.-hydroxy- (10 mol EO average molar ratio), is a synthetic compound primarily used in cosmetic products for its cleansing properties. It is part of the nonoxynol family, which consists of nonionic surfactants. These surfactants are known for their ability to reduce the surface tension of water, making it easier to remove dirt, oil, and other impurities from the skin.
The ingredient is often referred to by other names, such as Nonoxynol-10 or simply N-10. Its chemical composition includes a nonylphenol group attached to a polyethylene glycol chain, with an average of 10 ethylene oxide units. This structure allows it to effectively interact with both water and oil molecules, making it an efficient cleansing agent.
Nonyl Nonoxynol-10 has a history rooted in industrial applications before it found its way into the cosmetic industry. Initially, it was used in detergents and industrial cleaners due to its potent surfactant properties. Over time, its effectiveness in breaking down oils and dirt led to its adoption in personal care products, particularly in formulations designed to cleanse the skin and hair.
The manufacturing process of Nonyl Nonoxynol-10 involves the ethoxylation of nonylphenol. This process starts with the reaction of nonylphenol with ethylene oxide, which adds ethylene oxide units to the nonylphenol molecule. The number of ethylene oxide units can vary, but for Nonyl Nonoxynol-10, the average is around 10 units. This controlled chemical reaction results in a compound that is both hydrophilic (water-attracting) and lipophilic (oil-attracting), making it an ideal ingredient for cleansing formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Nonyl Nonoxynol-10:
Nonyl Nonoxynol-10 is primarily used as a cleansing agent in cosmetic products. This means it helps to remove dirt, oil, and other impurities from the skin. When you use a product containing this ingredient, it works by breaking down and emulsifying the oils and grime on your skin, making it easier to wash them away. This leaves your skin feeling clean and refreshed.
Another key benefit of Nonyl Nonoxynol-10 is its ability to act as an emulsifier. In the world of cosmetics, an emulsifier is a substance that helps to mix water and oil, which typically do not blend well together. This is crucial for creating stable and consistent formulations in products like lotions and creams. By ensuring that the water and oil components stay mixed, Nonyl Nonoxynol-10 helps to maintain the texture and effectiveness of the product.
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-10 is generally considered safe for use in cosmetic products, but like any ingredient, it may cause side effects in some individuals. Here are some potential side effects of topical application:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Nonyl Nonoxynol-10 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from Nonyl Nonoxynol-10 are relatively uncommon, but they can occur. It is recommended to conduct a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions.
Nonyl Nonoxynol-10 has a comedogenic rating of 1, which means it is considered to be minimally comedogenic. This indicates that it is unlikely to clog pores and cause acne or breakouts, making it generally suitable for people prone to blemishes and acne.
