Polysilicone-17, also known by its more technical name “Siloxanes and silicones, diphenyl, phenyl oxy, methyl oxy, crosslinked,” is a synthetic polymer primarily used in the cosmetic industry for its skin conditioning properties. This ingredient belongs to the broader family of silicones, which are renowned for their versatility and beneficial effects in personal care products.
The history of Polysilicone-17 in cosmetics dates back to the increasing demand for advanced skincare solutions that offer more than just basic hydration. As the beauty industry evolved, so did the need for ingredients that could provide a silky, smooth feel while also conditioning the skin. Researchers and chemists developed Polysilicone-17 to meet these needs, leveraging the unique properties of silicones to create a compound that could enhance the texture and performance of various cosmetic formulations.
The production of Polysilicone-17 involves a complex chemical process where siloxane polymers are crosslinked with diphenyl, phenyl oxy, and methyl oxy groups. This crosslinking process is crucial as it imparts the ingredient with its distinctive properties, such as flexibility, durability, and a non-greasy finish. The result is a high-performance silicone that can be seamlessly integrated into creams, lotions, and other skincare products to improve their overall feel and effectiveness.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polysilicone-17:
Polysilicone-17 is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When applied in cosmetic formulations, it can make your skin feel smoother and softer. It works by forming a protective barrier on the skin’s surface, which helps to lock in moisture and prevent dryness. This can be particularly beneficial for those with dry or sensitive skin, as it helps to keep the skin hydrated and comfortable.
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).
Polysilicone-17 is generally considered safe for use in cosmetic products, with a low potential for causing adverse reactions. However, as with any ingredient, there are some considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polysilicone-17 during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from Polysilicone-17 are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that you do not have a sensitivity to this ingredient.
Polysilicone-17 has a comedogenicity rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
