Undeceth-7, also known by its chemical name Poly(oxy-1,2-ethanediyl), .alpha.-hydroxy-.omega.-(undecyloxy)- (7 mol EO average molar ratio), is a versatile ingredient commonly found in various cosmetic products. It belongs to a family of compounds known as ethoxylated alcohols, which are synthesized by reacting fatty alcohols with ethylene oxide. In this case, the fatty alcohol is derived from undecyl alcohol, a substance that can be sourced from natural fats and oils or synthesized in a lab.
Historically, the use of ethoxylated alcohols in cosmetics dates back several decades. They were initially developed to improve the texture and performance of personal care products. Over time, their multifunctional properties made them a staple in the formulation of skincare and haircare items. Undeceth-7, in particular, has gained popularity due to its balanced hydrophilic-lipophilic nature, making it an effective emulsifier and cleanser.
The production of Undeceth-7 involves a chemical process called ethoxylation. This process starts with undecyl alcohol, which undergoes a reaction with ethylene oxide. The result is a compound with an average of seven ethylene oxide units per molecule, giving it the ability to attract both water and oil. This unique characteristic allows Undeceth-7 to function effectively in various cosmetic formulations, providing skin conditioning, emollient, cleansing, and emulsifying benefits.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Undeceth-7:
Undeceth-7 is known for its skin conditioning properties. This means it helps to keep your skin feeling soft, smooth, and hydrated. When included in skincare products, it can improve the overall texture and appearance of your skin, making it feel more supple and less dry. Essentially, it acts as a moisturizer that enhances your skin’s natural barrier, helping to retain moisture and protect against environmental stressors.
As an emollient, Undeceth-7 works to soften and soothe the skin. It forms a protective layer on the skin’s surface, which can help to prevent water loss and keep the skin hydrated. This is particularly beneficial for those with dry or sensitive skin, as it can provide a calming effect and reduce the feeling of roughness or irritation.
Undeceth-7 also serves as a cleansing agent. It helps to remove dirt, oil, and impurities from the skin, making it a common ingredient in cleansers and makeup removers. Its ability to mix with both water and oil allows it to effectively break down and wash away residues, leaving your skin feeling fresh and clean without stripping away its natural oils.
In addition to its other benefits, Undeceth-7 acts as an emulsifier. This means it helps to blend together ingredients that typically don’t mix well, such as oil and water. By stabilizing these mixtures, it ensures that products like lotions and creams have a consistent texture and effectiveness. This is crucial for the performance and shelf-life of many cosmetic products.
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).
Undeceth-7 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 of Undeceth-7:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Undeceth-7 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Undeceth-7 are relatively uncommon, but it is always prudent to perform a patch test before widespread usage to ensure there is no sensitivity or allergic reaction.
In terms of comedogenicity, Undeceth-7 has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that Undeceth-7 is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
