One of the key ingredients in the sunscreen product portfolio is a new water-based synthetic film former. The new film polymer is a hybrid blend of silicones and organic acrylates that offers formulators maximum process flexibility while delivering high product performance in delivering high SPF and long-lasting abrasion resistance, which is a priority for Asian consumers Expected.
The polymer is a white liquid emulsion and the recommended maximum usage level is 10%. This water-based film former is designed to provide the long-lasting wear resistance of traditional silicone acrylate technology while being a more affordable silicone solution for mass market products. The polymer has excellent sensory properties and is ideal for skin and sun care products, exhibiting low viscosity, high smoothness and slip upon absorption. Its tactile properties are soft but not brittle, and the polymer is highly washable.
The blended film former performed as well as the baseline in testing while also exhibiting high hydrophobicity, high sebum repellency and high film flexibility. Water-based film formers form a continuous film with excellent wash and scrub resistance. Its film flexibility provides wearing comfort and is aesthetically pleasing to consumers, while its long-lasting benefits provide a beneficial skin care experience, protecting skin from the sun’s harmful rays.
In addition to providing many benefits to the end user, this ingredient also offers many advantages to formulators. As a water-based film former, it offers greater formulation and manufacturing process flexibility as it achieves optimal performance in pure film, water-in-oil and oil-in-water formulations. The polymer is also readily compatible with common cosmetic ingredients, meaning formulators can bring the sensory benefits consumers expect into their sunscreen, skin care and even cosmetic products like alphabet creams.
