Undeceth-5 Carboxylic Acid, also known by its more technical name Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(undecyloxy)- (4 mol EO average molar ratio), is a synthetic compound primarily used in the cosmetic industry for its cleansing properties. This ingredient is part of the larger family of ethoxylated alcohols, which are commonly used in various personal care products. Another name you might encounter for this ingredient is Undecylenic Acid Ethoxylate.
The history of Undeceth-5 Carboxylic Acid in cosmetics dates back to the mid-20th century when the demand for more effective and milder cleansing agents began to rise. Researchers were exploring various ethoxylated compounds for their ability to improve the texture and efficacy of cleansing products. Over time, Undeceth-5 Carboxylic Acid emerged as a popular choice due to its balanced performance and relatively low irritation potential.
The production of Undeceth-5 Carboxylic Acid involves a chemical process known as ethoxylation. This process starts with undecylenic acid, a naturally occurring fatty acid derived from castor oil. The undecylenic acid undergoes a reaction with ethylene oxide, resulting in the formation of a polyoxyethylene chain. The average molar ratio of ethylene oxide units in this compound is four, which is indicated by the “5” in its name. This ethoxylated product is then further modified to introduce a carboxymethyl group, enhancing its solubility and effectiveness as a cleansing agent.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Undeceth-5 Carboxylic Acid:
Undeceth-5 Carboxylic Acid is primarily recognized 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 is a fancy way of saying it helps water to mix with oil and dirt so they can be rinsed away. This makes it an effective 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).
Undeceth-5 Carboxylic Acid is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Undeceth-5 Carboxylic Acid during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to Undeceth-5 Carboxylic Acid 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.
In terms of comedogenicity, Undeceth-5 Carboxylic Acid has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means that it is unlikely to clog pores and is generally suitable for people who are prone to acne, blemishes, or breakouts.
