Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone, also known by its more technical name Siloxanes and Silicones, 11-(2-(nonafluorononyl)ethoxy)-11-oxoundecyl methyl, hexacosyl methyl, dimethyl, is a synthetic ingredient primarily used in cosmetic formulations for its skin conditioning properties. This mouthful of a name might seem intimidating, but it essentially refers to a specialized type of silicone.
The ingredient is derived from a combination of siloxanes and silicones, which are compounds made up of silicon, oxygen, and other elements like carbon and hydrogen. These compounds are known for their flexibility, water-repellent properties, and ability to form a breathable barrier on the skin. The “perfluorononylethyl” part of the name indicates the presence of fluorinated groups, which enhance the ingredient’s ability to repel water and oils, making it particularly useful in long-lasting and waterproof cosmetic products.
Historically, silicones have been used in cosmetics since the mid-20th century, but the more specialized forms like Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone are relatively recent innovations. These advanced silicones were developed to meet the growing demand for high-performance, multifunctional ingredients in skincare and makeup products. They offer enhanced benefits compared to traditional silicones, such as improved texture, longer wear, and better compatibility with other ingredients.
The manufacturing process of Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone involves several steps. It starts with the synthesis of basic silicone polymers, which are then chemically modified to introduce the perfluorononylethyl and carboxydecyl groups. These modifications are typically achieved through complex chemical reactions that require precise control over reaction conditions to ensure the desired properties are achieved. The final product is a highly specialized silicone that combines the best features of traditional silicones with enhanced performance characteristics.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone:
Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When applied in cosmetic formulations, it can make the skin feel softer and smoother, providing a more pleasant tactile experience. This can be particularly beneficial in products like moisturizers, lotions, and creams where a silky, non-greasy finish is desired.
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 Carboxydecyl Hexacosyl Dimethicone is generally considered safe for topical 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 Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone during pregnancy are lacking. It is advisable for these individuals to consult a healthcare professional for further advice.
Side effects and adverse reactions from this ingredient are relatively uncommon. However, it is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
On a comedogenicity scale of 0 to 5, Perfluorononylethyl Carboxydecyl Hexacosyl Dimethicone is rated as a 1, meaning it is minimally comedogenic. This is generally good news for individuals prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
