Perfluorononylethyl PEG-8 Dimethicone, also known by its more technical name Siloxanes and Silicones, 2-(nonafluorononyl)ethyl methyl, 3-hydropoly(oxyethylene)oxypropyl methyl, dimethyl (8 mol EO average molar ratio), is a synthetic ingredient commonly used in cosmetic formulations. This compound is part of the larger family of silicones, which are widely appreciated in the beauty industry for their versatile properties.
The ingredient is derived from a combination of perfluorinated compounds and silicones, giving it unique characteristics that make it particularly effective for skin conditioning. The “PEG-8” part of its name refers to the polyethylene glycol component, which helps to enhance its solubility and spreadability on the skin.
Historically, silicones have been used in cosmetics since the mid-20th century, primarily for their ability to provide a smooth, silky texture and to form a protective barrier on the skin. The specific development of Perfluorononylethyl PEG-8 Dimethicone came about as scientists sought to create more specialized silicone compounds that could offer additional benefits, such as improved moisture retention and enhanced skin feel.
The manufacturing process of Perfluorononylethyl PEG-8 Dimethicone involves a series of chemical reactions that combine perfluorinated alkyl groups with silicone-based polymers. This synthesis results in a compound that boasts both hydrophobic (water-repelling) and hydrophilic (water-attracting) properties, making it highly effective in various skincare and cosmetic applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Perfluorononylethyl PEG-8 Dimethicone:
Perfluorononylethyl PEG-8 Dimethicone is primarily known for its skin conditioning properties. This means that it helps to maintain the skin in good condition by improving its appearance and texture. When applied to the skin, it forms a smooth, protective layer that can help to lock in moisture, making the skin feel softer and more hydrated. This is particularly beneficial for individuals with dry or rough skin, as it can provide a more supple and smooth complexion.
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).
Perfluorononylethyl PEG-8 Dimethicone is generally considered safe for topical 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 Perfluorononylethyl PEG-8 Dimethicone 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 Perfluorononylethyl PEG-8 Dimethicone are generally uncommon. However, it is always recommended to conduct a patch test before widespread usage to ensure that the ingredient does not cause any adverse reactions on your skin.
In terms of comedogenicity, Perfluorononylethyl PEG-8 Dimethicone is rated as a 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 individuals prone to acne, blemishes, or breakouts.
