PEG-5 Glyceryl Sesquioleate, also known by its chemical name 1,2,3-Propanetriol, esters with 9-(Z)-octdecenoic acid (2:3), ethoxylated (5 mol EO average molar ratio), is a versatile ingredient commonly found in cosmetic products. This compound is primarily used as an emulsifying agent, which means it helps blend water and oil-based ingredients together, creating a stable and homogenous mixture.
The ingredient is derived from glycerin and oleic acid, which are both naturally occurring substances. Glycerin is a simple polyol compound often sourced from plant oils, while oleic acid is a fatty acid commonly found in olive oil. The “PEG-5” part of the name indicates that the compound has been ethoxylated with an average of five units of ethylene oxide, enhancing its emulsifying properties.
Historically, the use of emulsifying agents in cosmetics dates back to ancient times when natural substances like beeswax and lecithin were used to create creams and lotions. With advancements in chemistry, more efficient and stable emulsifiers like PEG-5 Glyceryl Sesquioleate were developed. This ingredient gained popularity in the cosmetic industry due to its ability to create smooth, non-greasy formulations that are easy to apply and absorb into the skin.
The manufacturing process of PEG-5 Glyceryl Sesquioleate involves the esterification of glycerin with oleic acid, followed by ethoxylation. This process results in a compound that is highly effective at reducing the surface tension between oil and water, allowing them to mix seamlessly. The final product is a clear, viscous liquid that can be easily incorporated into various cosmetic formulations, from creams and lotions to serums and cleansers.
In this section, we will delve into the officially recognized cosmetic benefits and uses of PEG-5 Glyceryl Sesquioleate:
PEG-5 Glyceryl Sesquioleate is primarily used as an emulsifying agent in cosmetic formulations. This means it helps to blend water and oil-based ingredients together, which are typically difficult to mix. By doing so, it ensures that the product has a consistent texture and appearance, making it more effective and pleasant to use. For example, in lotions and creams, this ingredient helps to create a smooth, homogenous mixture that spreads easily on 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).
PEG-5 Glyceryl Sesquioleate is generally considered safe for use in cosmetic products. 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 PEG-5 Glyceryl Sesquioleate 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 PEG-5 Glyceryl Sesquioleate are relatively uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, PEG-5 Glyceryl Sesquioleate is rated at a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means it is unlikely to clog pores, making it generally suitable for individuals prone to acne, blemishes, or breakouts.
