Polyglyceryl-6 Isostearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, isooctadecanoates (1:1) (6 mol glycerol average molar ratio), is a versatile ingredient primarily used as an emulsifier in cosmetic products. This ingredient is derived from glycerol, a natural compound commonly found in fats and oils, and isostearic acid, a branched-chain fatty acid. The combination of these components results in a compound that helps to blend oil and water-based ingredients, ensuring a stable and uniform product.
The history of Polyglyceryl-6 Isostearate in cosmetics is relatively recent, emerging as a response to the growing demand for more effective and skin-friendly emulsifiers. Traditional emulsifiers often posed challenges such as skin irritation or instability in formulations. Researchers sought to develop alternatives that could offer better performance with fewer drawbacks, leading to the creation of polyglyceryl-based emulsifiers like Polyglyceryl-6 Isostearate.
The production process of Polyglyceryl-6 Isostearate involves the polymerization of glycerol, resulting in a polyglycerol backbone. This backbone is then esterified with isostearic acid, creating a compound that can effectively reduce the surface tension between oil and water, allowing them to mix seamlessly. This method not only enhances the emulsifying properties but also ensures that the ingredient is mild and suitable for various skin types.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-6 Isostearate:
Polyglyceryl-6 Isostearate is primarily used as an emulsifying agent in cosmetic formulations. This means it helps to mix water and oil-based ingredients, which typically don’t blend well together. By doing so, it ensures that the product has a consistent texture and stability, preventing the ingredients from separating over time. This is crucial for products like lotions, creams, and other emulsions, where a smooth and uniform consistency is desired.
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-6 Isostearate is generally considered to be a safe and effective emulsifying agent in cosmetic formulations. 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-6 Isostearate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Polyglyceryl-6 Isostearate are relatively uncommon. However, it is always prudent to perform a patch test before widespread usage to ensure that you do not have an adverse reaction to the ingredient.
In terms of comedogenicity, Polyglyceryl-6 Isostearate has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means that it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
