Polyglyceryl-10 Diisostearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, isooctadecanoates (1:2) (10 mol glycerol average molar ratio), is a versatile ingredient commonly used in cosmetic formulations. This compound is derived from glycerol, a naturally occurring substance, and isostearic acid, a fatty acid. The “10” in its name indicates that it is a polymer made from ten units of glycerol, making it a polyglycerol ester.
The history of Polyglyceryl-10 Diisostearate in cosmetics is relatively recent, emerging as a response to the growing demand for more effective and skin-friendly emulsifiers. Emulsifiers are crucial in cosmetic products as they help blend water and oil components, creating a stable and homogenous mixture. This ingredient has gained popularity due to its ability to provide a smooth texture and enhance the overall feel of cosmetic products.
The production of Polyglyceryl-10 Diisostearate involves a chemical reaction known as esterification. In this process, glycerol undergoes polymerization to form polyglycerol, which is then reacted with isostearic acid. The result is a compound that combines the hydrophilic (water-attracting) properties of glycerol with the lipophilic (oil-attracting) properties of isostearic acid. This unique combination makes it an effective emulsifier, capable of stabilizing formulations and improving the consistency of creams, lotions, and other cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-10 Diisostearate:
Polyglyceryl-10 Diisostearate 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 lotions, creams, and other beauty products have a smooth and consistent texture, preventing them from separating into oily and watery layers. This is crucial for the effectiveness and aesthetic appeal of many skincare and 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).
Polyglyceryl-10 Diisostearate is generally considered safe for use in cosmetic products. It is known for its emulsifying properties, which help to blend water and oil-based ingredients, creating a stable and uniform product. However, as with any cosmetic 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-10 Diisostearate 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.
Adverse reactions to Polyglyceryl-10 Diisostearate are relatively uncommon. However, as with any new skincare product, it is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
Polyglyceryl-10 Diisostearate has a comedogenic rating of 1, meaning it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts, as it is considered to be non-comedogenic.
