Glycerin/Oxybutylene Copolymer Stearyl Ether, also known by its chemical name 1,2,3-Propanetriol, polymer with ethyloxirane, octadecyl monoethers, is a synthetic ingredient commonly used in cosmetic formulations. This compound is derived from glycerin, a well-known humectant, and ethyloxirane, a type of epoxide. The addition of a stearyl ether group, which is derived from stearyl alcohol, helps to enhance its emollient properties.
The history of Glycerin/Oxybutylene Copolymer Stearyl Ether in cosmetics is relatively recent, emerging as a response to the growing demand for multifunctional ingredients that can provide both hydration and a smooth texture. Initially, glycerin was widely used for its moisturizing capabilities, but it had limitations in terms of texture and feel. By polymerizing glycerin with ethyloxirane and adding a stearyl ether group, chemists were able to create a more versatile ingredient that offers improved sensory attributes while retaining the moisturizing benefits of glycerin.
The production process involves a series of chemical reactions starting with the polymerization of glycerin and ethyloxirane. This polymerization creates a copolymer that is then reacted with stearyl alcohol to form the final product. The result is a compound that combines the hydrating properties of glycerin with the emollient and texturizing benefits of stearyl ether, making it a valuable addition to a wide range of cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Glycerin/Oxybutylene Copolymer Stearyl Ether:
Glycerin/Oxybutylene Copolymer Stearyl Ether is primarily known for its emollient properties. In simple terms, an emollient is a substance that helps to soften and smooth the skin. When you apply a product containing this ingredient, it forms a protective barrier on the skin’s surface. This barrier helps to lock in moisture, making your skin feel softer and more hydrated. It’s particularly beneficial for those with dry or rough skin, as it can provide immediate relief and a smoother texture.
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).
Glycerin/Oxybutylene Copolymer Stearyl Ether is generally considered safe for topical 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 Glycerin/Oxybutylene Copolymer Stearyl Ether during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from this ingredient are relatively uncommon. However, it is always recommended to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the product.
In terms of comedogenicity, Glycerin/Oxybutylene Copolymer Stearyl Ether 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 means that it is unlikely to clog pores and cause acne or breakouts, making it suitable for individuals prone to blemishes.
