Polyglyceryl-10 Heptastearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, octadecanoates (1:2) (10 mol glycerol average molar ratio), is a synthetic compound commonly used in cosmetic formulations. This ingredient is derived from glycerin, a natural compound found in fats and oils, and stearic acid, a fatty acid that is also naturally occurring. The “10” in its name indicates that it is a polymer made up of ten glycerol units.
The use of Polyglyceryl-10 Heptastearate in cosmetics is relatively modern, stemming from advancements in cosmetic chemistry that sought to create more effective and stable skin conditioning agents. Its development was driven by the need for ingredients that could provide hydration and improve the texture of skincare products without causing irritation or adverse reactions.
The manufacturing process of Polyglyceryl-10 Heptastearate involves the polymerization of glycerol, followed by esterification with stearic acid. This process results in a molecule that is both hydrophilic (water-attracting) and lipophilic (oil-attracting), making it an excellent emulsifier and skin conditioning agent. Its unique structure allows it to blend well with both water and oil, which is why it is often found in creams, lotions, and other emulsified products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-10 Heptastearate:
Polyglyceryl-10 Heptastearate 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 keep your skin feeling soft, smooth, and hydrated. Essentially, it acts as a moisturizer, ensuring that your skin doesn’t dry out and remains supple. This is particularly beneficial for those with dry or sensitive skin, as it can help to alleviate dryness and provide a soothing effect.
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 Heptastearate is generally considered safe for use in cosmetic products. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyglyceryl-10 Heptastearate 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 Heptastearate are relatively 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.
Polyglyceryl-10 Heptastearate has a comedogenic rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
