PEG-10 Phytosterol, also known by its chemical name (3-.beta.)-Sigmast-5-en-3-ol, ethoxylated (10 mol EO average molar ratio), is a cosmetic ingredient primarily used for its emulsifying properties. Derived from plant sterols, which are naturally occurring compounds found in the cell membranes of plants, PEG-10 Phytosterol is a modified version that has been ethoxylated to enhance its functionality in cosmetic formulations.
The history of PEG-10 Phytosterol in cosmetics dates back to the ongoing quest for more effective and skin-friendly emulsifiers. Emulsifiers are crucial in the cosmetic industry as they help blend water and oil-based ingredients, creating stable and homogenous products. PEG-10 Phytosterol emerged as a valuable ingredient due to its ability to provide a smooth texture and improve the stability of cosmetic products.
The production of PEG-10 Phytosterol involves a chemical process known as ethoxylation. This process adds ethylene oxide molecules to the phytosterol, resulting in a compound that can better interact with both water and oil. The “10 mol EO average molar ratio” indicates that, on average, ten ethylene oxide units are added to each molecule of phytosterol. This modification enhances the emulsifying properties of the phytosterol, making it more effective in creating stable emulsions in various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of PEG-10 Phytosterol:
PEG-10 Phytosterol is primarily used as an emulsifying agent in cosmetic formulations. But what does that mean for you? In simple terms, an emulsifying agent helps to mix ingredients that typically don’t blend well together, like oil and water. This is crucial in creating a stable and uniform product, ensuring that the texture and consistency of your creams, lotions, and other beauty products remain smooth and homogenous. Without emulsifiers, you might find your favorite moisturizer separating into layers, which is not only unappealing but also less effective.
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-10 Phytosterol 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-10 Phytosterol 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-10 Phytosterol are relatively uncommon, but they can occur. It is recommended to conduct a patch test before widespread usage to ensure there is no adverse reaction.
In terms of comedogenicity, PEG-10 Phytosterol 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 it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
