Polyglyceryl-10 Isostearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, isooctadecanoates (1:1) (10 mol glycerol average molar ratio), is a versatile ingredient commonly found in cosmetic products. This compound is derived from glycerol, a natural substance often sourced from plant oils, and isostearic acid, a fatty acid that can be obtained from both animal and vegetable fats. The “10” in its name indicates that it is a polymer made up of ten glycerol units on average.
The history of Polyglyceryl-10 Isostearate in cosmetics is relatively recent, emerging as a response to the growing demand for more skin-friendly and sustainable ingredients. As consumers became more conscious of the ingredients in their skincare products, manufacturers sought alternatives to traditional surfactants and emulsifiers that could offer similar benefits without the associated drawbacks. Polyglyceryl-10 Isostearate was developed to meet these needs, providing a gentle yet effective option for skin conditioning.
The production of Polyglyceryl-10 Isostearate involves a process called esterification, where glycerol is polymerized to form polyglycerol, which is then reacted with isostearic acid. This reaction results in a compound that combines the hydrophilic (water-attracting) properties of glycerol with the lipophilic (oil-attracting) properties of isostearic acid, making it an excellent emulsifier and skin conditioning agent. This unique combination allows it to help stabilize formulations and improve the texture and feel of cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-10 Isostearate:
Polyglyceryl-10 Isostearate is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When used in cosmetic formulations, it works to improve the appearance and feel of the skin. It can make the skin feel smoother, softer, and more supple. This is particularly beneficial for those with dry or rough skin, as it helps to restore a healthy, hydrated look and feel.
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 Isostearate is generally considered safe for use in cosmetic products. It is well-tolerated by most skin types and is not known to be a common allergen. However, as with any ingredient, there is always a possibility of side effects, especially for individuals with sensitive skin or specific allergies.
Regarding individuals who are pregnant or breastfeeding, there is a lack of specific data on the topical usage of Polyglyceryl-10 Isostearate 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 Isostearate are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure there is no adverse reaction.
Polyglyceryl-10 Isostearate has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts.
