Solesphere™ microspherical silica gels enhance the surface smoothness and dispersibility of cosmetics and skincare products. They have a lower coefficient of friction than titanium dioxide and other popular fillers. On a molecular level, they move more freely to provide a superior tactile feel.
AGC recently released new Solesphere H-52 and H-53 grades that can be added to cosmetics, skincare and sunscreen formulations to boost SPF and stability. These 5 µm particle size gels have high specific surface areas and large pores to more effectively scatter light. Formulators can add these gels to their lotions and cosmetics to achieve the same SPF using less chemicals and active pharmaceutical ingredients (APDs). In addition, formulations made with Solesphere gels are less likely to lose their SPF effectiveness over time.
Solesphere H-52 has a 10 µm pore diameter and oil absorption level of 300 mL/g, while Solesphere H-52 has an 11 µm pore diameter and an oil absorption level of 400 mL/g.
