Polyglyceryl-2 Lanolin Alcohol Ether, also known as 1,2,3-Propanetriol, homopolymer, ethers with lanolin alcohols (1:1) (2 mol glycerol average molar ratio), is a cosmetic ingredient primarily used for its emulsifying properties. This compound is derived from lanolin alcohols, which are sourced from the wool of sheep, and polyglycerol, a polymer of glycerol. The combination of these two components results in a versatile ingredient that helps to blend oil and water-based ingredients in cosmetic formulations, ensuring a stable and homogenous product.
The history of Polyglyceryl-2 Lanolin Alcohol Ether in cosmetics dates back to the ongoing quest for more effective and skin-friendly emulsifiers. Lanolin, a natural substance extracted from sheep’s wool, has been used for centuries for its moisturizing properties. By chemically modifying lanolin alcohols with polyglycerol, scientists were able to create an ingredient that not only retains the beneficial properties of lanolin but also enhances the emulsifying capabilities, making it a valuable addition to modern cosmetic products.
The production of Polyglyceryl-2 Lanolin Alcohol Ether involves a chemical reaction between lanolin alcohols and polyglycerol. This process typically includes the esterification of lanolin alcohols with polyglycerol, resulting in a compound that can effectively stabilize emulsions. The average molar ratio of glycerol in this compound is around 2, which indicates the degree of polymerization and helps in achieving the desired emulsifying properties. This manufacturing process ensures that the final product is both effective and safe for use in a variety of cosmetic applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-2 Lanolin Alcohol Ether:
Polyglyceryl-2 Lanolin Alcohol Ether is primarily used as an emulsifying agent in cosmetic formulations. This means it helps to blend water and oil components together, creating a stable and uniform mixture. Without emulsifiers, products like creams and lotions would separate into their individual components, making them less effective and less appealing to use. By ensuring that the ingredients are well-mixed, Polyglyceryl-2 Lanolin Alcohol Ether helps to improve the texture and consistency of the product, making it smoother and easier to apply.
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).
Polyglyceryl-2 Lanolin Alcohol Ether 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 Polyglyceryl-2 Lanolin Alcohol Ether during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from Polyglyceryl-2 Lanolin Alcohol Ether are relatively uncommon. However, it is always a good practice to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Polyglyceryl-2 Lanolin Alcohol Ether is rated at a 2 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This means it has a low potential to clog pores, but individuals who are prone to acne, blemishes, or breakouts should still exercise caution when using products containing this ingredient.
