Noneth-8, also known as Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-nonyloxy- (8 mol EO average molar ratio), is a synthetic compound primarily used in cosmetic products for its cleansing properties. It is part of a larger family of nonionic surfactants, which are compounds that help to reduce surface tension, allowing for the easy removal of dirt and oils from the skin. You might also encounter Noneth-8 under other names like Nonoxynol-8 or Nonylphenol Ethoxylate-8.
The history of Noneth-8 in cosmetics dates back to the mid-20th century when the demand for more effective and versatile cleansing agents began to rise. Scientists discovered that by ethoxylating nonylphenol, they could create a compound that was not only effective at breaking down oils and dirt but also relatively mild on the skin. This made it an attractive ingredient for a variety of personal care products, from shampoos to facial cleansers.
Noneth-8 is produced through a chemical process known as ethoxylation, where ethylene oxide is reacted with nonylphenol. The “8 mol EO” in its name indicates that, on average, eight units of ethylene oxide are added to each molecule of nonylphenol. This process results in a molecule that has both hydrophilic (water-attracting) and lipophilic (oil-attracting) properties, making it an effective surfactant.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Noneth-8:
Noneth-8 is primarily known for its cleansing properties. This means that it helps to remove dirt, oil, and other impurities from the skin. When included in cosmetic products like facial cleansers, body washes, or shampoos, Noneth-8 works by breaking down and emulsifying the oils and debris on the skin or hair, making it easier to rinse them away. This leaves your skin feeling fresh and clean, and your hair free from buildup.
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).
Noneth-8 is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Noneth-8 during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice.
Side effects and adverse reactions from Noneth-8 are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Noneth-8 has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
