Choleth-10, also known as (3beta)-Cholest-5-en-3-ol, ethoxylated (10 mol EO average molar ratio), is a versatile ingredient commonly found in various cosmetic products. This compound is derived from cholesterol, a natural substance found in the cell membranes of all animal tissues. The “10” in Choleth-10 indicates that it has been ethoxylated with an average of 10 moles of ethylene oxide, a process that enhances its solubility and functionality in formulations.
The use of Choleth-10 in cosmetics has a relatively recent history, emerging as a popular ingredient due to its dual functionality as both a cleansing and emulsifying agent. Initially, the cosmetic industry sought alternatives to traditional surfactants and emulsifiers that could offer better skin compatibility and performance. Choleth-10 fit the bill perfectly, providing gentle yet effective cleansing properties while also helping to stabilize and blend formulations.
The production of Choleth-10 involves a chemical reaction where cholesterol is treated with ethylene oxide. This ethoxylation process modifies the cholesterol molecule, making it more hydrophilic (water-attracting) and thus more suitable for use in water-based cosmetic formulations. The result is a non-ionic surfactant that can effectively cleanse the skin without stripping it of its natural oils, while also helping to create stable emulsions in creams and lotions.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Choleth-10:
Choleth-10 is known for its cleansing properties. This means it helps to remove dirt, oil, and other impurities from the skin. When included in a cosmetic product, Choleth-10 works by breaking down and emulsifying these unwanted substances, making it easier to wash them away. This can leave your skin feeling fresh, clean, and free from the buildup that can clog pores and cause breakouts.
Another key benefit of Choleth-10 is its ability to act as an emulsifier. In simple terms, this means it helps to blend ingredients that typically don’t mix well together, like oil and water. By stabilizing these mixtures, Choleth-10 ensures that the product maintains a consistent texture and effectiveness. This is particularly important in creams, lotions, and other formulations where a smooth, uniform consistency is crucial for proper application and performance.
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).
Choleth-10 is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Choleth-10 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Choleth-10 are relatively uncommon, but it is always prudent to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Choleth-10 has a comedogenic rating of 1, which means it is unlikely to clog pores. This makes it a suitable option for individuals prone to acne, blemishes, or breakouts.
