Bis-Benzyl Undecanoate Dimethicone, also known by its more technical name “Siloxanes and Silicones, di-Me, 11-oxo-11-(phenylmethoxy)undecyl group-terminated,” is a specialized silicone-based compound used primarily in cosmetic formulations. This ingredient is part of the larger family of silicones, which are renowned for their versatile applications in skincare and beauty products. Silicones are synthetic polymers made up of repeating units of siloxane, a chain of alternating silicon and oxygen atoms, often combined with carbon and hydrogen.
The history of silicones in cosmetics dates back to the mid-20th century when their unique properties—such as providing a smooth, silky texture and forming a breathable barrier on the skin—began to be recognized. Over time, chemists have developed more specialized silicones like Bis-Benzyl Undecanoate Dimethicone to meet specific needs in skincare and cosmetic formulations. This particular compound is designed to offer skin conditioning benefits while also controlling the viscosity of the product, making it easier to apply and more pleasant to use.
The production of Bis-Benzyl Undecanoate Dimethicone involves a series of chemical reactions that introduce the 11-oxo-11-(phenylmethoxy)undecyl group to the silicone backbone. This modification enhances its ability to condition the skin and stabilize the viscosity of the final product. The process typically starts with the basic silicone polymer, which is then chemically altered to include the desired functional groups, resulting in a compound that combines the best of both worlds: the beneficial properties of silicones and the specific advantages of the added functional groups.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Bis-Benzyl Undecanoate Dimethicone:
One of the primary benefits of Bis-Benzyl Undecanoate Dimethicone is its skin conditioning properties. This means that it helps to maintain the skin in good condition by improving its appearance and texture. In practical terms, this ingredient can make your skin feel softer and smoother, providing a more pleasant tactile experience. It can also help to reduce the appearance of dry or flaky skin, giving your complexion a healthier and more hydrated look.
Another significant benefit of Bis-Benzyl Undecanoate Dimethicone is its ability to control the viscosity of cosmetic formulations. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, this ingredient ensures that the product has the right consistency for easy application and spreadability. This means that your creams, lotions, and serums will glide on smoothly without feeling too runny or too thick, enhancing the overall user experience.
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).
Bis-Benzyl Undecanoate Dimethicone is generally considered safe for topical application 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 Bis-Benzyl Undecanoate Dimethicone during pregnancy are lacking. It is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from Bis-Benzyl Undecanoate Dimethicone are uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, Bis-Benzyl Undecanoate Dimethicone is rated as a 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating indicates that it is unlikely to clog pores and is generally suitable for individuals prone to acne, blemishes, or breakouts.
