Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is a synthetic polymer that finds its way into a variety of cosmetic products. Chemically, it is the sodium salt of a copolymer composed of acrylic acid, methacrylic acid or one or more of its simple esters, and beheneth-25 methacrylate, crosslinked with methylene bis-acrylamide. This mouthful of a name can also be found under different aliases in ingredient lists, but its primary function remains consistent.
The history of Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer in cosmetics is relatively modern, emerging as the demand for more sophisticated and multifunctional skincare products grew. Initially, simpler polymers were used to achieve basic thickening and stabilizing effects. However, as the cosmetic industry evolved, there was a need for ingredients that could offer more than just viscosity control. This led to the development and incorporation of more complex polymers like Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer, which not only thickens formulations but also conditions the skin.
The production of this polymer involves a meticulous chemical process. It starts with the polymerization of acrylic and methacrylic acids or their esters, combined with beheneth-25 methacrylate. This mixture is then crosslinked using methylene bis-acrylamide, resulting in a stable and versatile polymer. The final product is a fine powder that can be easily incorporated into various cosmetic formulations, enhancing their texture and performance.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer:
Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its appearance and texture. When included in cosmetic formulations, this ingredient can make your skin feel smoother and softer, enhancing its overall look and feel. It works by forming a thin, protective layer on the skin’s surface, which helps to lock in moisture and keep the skin hydrated.
Another key benefit of Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is its ability to control the viscosity of cosmetic products. Viscosity refers to the thickness or thinness of a product. By adjusting the viscosity, this ingredient ensures that creams, lotions, and gels have the right consistency for easy application and absorption. This means your favorite skincare products won’t be too runny or too thick, making them more pleasant and effective to use.
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).
Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is generally considered safe for use in cosmetic products. It is widely used for its skin conditioning and viscosity controlling properties. 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 Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to this ingredient are uncommon, but it is always prudent to perform a patch test before widespread usage to ensure there is no sensitivity or allergic reaction.
In terms of comedogenicity, Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer 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 cause acne or breakouts, making it suitable for individuals prone to blemishes.
