Polyglyceryl-10 Distearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, octadecanoates (1:2) (10 mol glycerol average molar ratio), is a versatile emulsifying agent commonly used in cosmetic formulations. This ingredient is derived from glycerol, a naturally occurring compound, and stearic acid, a fatty acid typically sourced from vegetable oils. The “10” in its name indicates that it is a polymer of glycerol with an average of 10 glycerol units per molecule, making it a polyglycerol ester.
The use of polyglyceryl esters in cosmetics has a relatively recent history, gaining popularity as consumers and manufacturers alike sought more skin-friendly and environmentally sustainable alternatives to traditional emulsifiers. Polyglyceryl-10 Distearate emerged as a preferred choice due to its ability to create stable emulsions, which are essential for the consistency and performance of creams, lotions, and other topical products.
The manufacturing process of Polyglyceryl-10 Distearate involves the esterification of polyglycerol with stearic acid. This reaction typically occurs under controlled conditions to ensure the correct molecular structure and functionality. The resulting compound is a non-ionic surfactant, meaning it does not carry a charge, which contributes to its mildness and compatibility with a wide range of other cosmetic ingredients.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-10 Distearate:
Polyglyceryl-10 Distearate 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. In simpler terms, it ensures that your creams, lotions, and other skincare products have a smooth and consistent texture, preventing them from separating into oily and watery layers. This not only improves the aesthetic appeal of the product but also ensures that the active ingredients are evenly distributed, enhancing the overall effectiveness of the product.
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-10 Distearate is generally considered safe for use in cosmetic products. It is known for its emulsifying properties, which help to blend oil and water-based ingredients, creating a stable formulation. However, as with any cosmetic ingredient, there are potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, there is a lack of specific data and research on the topical usage of Polyglyceryl-10 Distearate during pregnancy. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Polyglyceryl-10 Distearate are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.
On the comedogenicity scale, Polyglyceryl-10 Distearate is rated as a 1, meaning it is considered to be minimally comedogenic. This low rating suggests that it is unlikely to clog pores or contribute to acne, making it generally suitable for people prone to blemishes or breakouts.
