Polyglyceryl-2 Laurate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, dodecanoates (1:1) (2 mol glycerol average molar ratio), is a versatile ingredient commonly used in cosmetic formulations. This compound is derived from glycerol and lauric acid, both of which are naturally occurring substances. Glycerol, also known as glycerin, is a simple polyol compound, while lauric acid is a saturated fatty acid found in various plant and animal fats, with coconut oil being a particularly rich source.
The history of Polyglyceryl-2 Laurate in cosmetics dates back to the increasing demand for more natural and skin-friendly emulsifiers. Traditional emulsifiers, often derived from petroleum sources, were found to be harsh on the skin and environmentally unfriendly. As a result, researchers began to explore more sustainable and gentle alternatives, leading to the development of polyglyceryl esters like Polyglyceryl-2 Laurate.
The manufacturing process of Polyglyceryl-2 Laurate involves the esterification of glycerol with lauric acid. This reaction typically occurs under controlled conditions, where glycerol molecules react with lauric acid to form a stable ester bond. The “2” in Polyglyceryl-2 Laurate indicates that, on average, two glycerol units are polymerized before being esterified with lauric acid. This specific structure allows it to function effectively as an emulsifier, helping to blend oil and water-based ingredients in cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-2 Laurate:
Polyglyceryl-2 Laurate is primarily used as an emulsifying agent in cosmetic formulations. This means it helps to mix water and oil components, which typically do not blend well together. By stabilizing these mixtures, it ensures that products like lotions, creams, and serums have a consistent texture and appearance. This not only enhances the user experience by making the product easier to apply, but it also ensures that the active ingredients are evenly distributed, providing uniform benefits across the skin.
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-2 Laurate 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 formulation. However, like any cosmetic ingredient, it is important to be aware of potential side effects and other considerations.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyglyceryl-2 Laurate during pregnancy 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-2 Laurate are generally uncommon. However, as with any new skincare product, it is recommended to conduct a patch test before widespread usage to ensure there are no adverse reactions.
Polyglyceryl-2 Laurate has a comedogenic rating of 1, which means it is considered to be minimally 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.
