Polyglyceryl-3 Diisostearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, isodecanoates (1:2) (3 mol glycerol average molar ratio), is a versatile ingredient commonly found in cosmetic products. This compound is derived from glycerol and isodecanoic acid, making it a synthetic ester. It is often referred to by other names such as Polyglyceryl-3 Distearate or simply PG3D.
The use of Polyglyceryl-3 Diisostearate in cosmetics has a relatively recent history. It was developed as part of the ongoing quest for more effective and skin-friendly emulsifiers. Emulsifiers are crucial in cosmetic formulations as they help blend water and oil components, ensuring a stable and homogenous product. Over time, Polyglyceryl-3 Diisostearate has gained popularity due to its excellent emulsifying properties and its ability to enhance the texture and feel of cosmetic products.
The production of Polyglyceryl-3 Diisostearate involves a chemical reaction between glycerol and isodecanoic acid. This process, known as esterification, results in the formation of a compound that can effectively bind water and oil molecules together. The “3” in its name indicates that three glycerol molecules are involved in the reaction, contributing to its unique properties. This ingredient is synthesized in controlled environments to ensure purity and consistency, making it a reliable choice for cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-3 Diisostearate:
Polyglyceryl-3 Diisostearate is primarily used as an emulsifying agent in cosmetic formulations. This means it helps to blend water and oil-based ingredients together, creating a stable and uniform mixture. Without emulsifiers, products like lotions and creams would separate, making them less effective and less pleasant to use. By ensuring that the ingredients are well-mixed, Polyglyceryl-3 Diisostearate helps to improve the texture and consistency of cosmetic products, making them 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-3 Diisostearate 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 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, there is a lack of specific data and research on the topical usage of Polyglyceryl-3 Diisostearate 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-3 Diisostearate are generally uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions on your skin.
In terms of comedogenicity, Polyglyceryl-3 Diisostearate is rated as a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores and cause acne or breakouts, making it suitable for individuals prone to blemishes or acne.
