The Solesphere brand H-52 and H-53 (INCIs: Silica) gels contain large pores and an increased surface area to scatter light, which means less UV-absorbing ingredients are needed in formulations.
According to the company, formulations made with Solesphere H-52 and H-53 silica gels are less likely to lose SPF effectiveness over time because they are less dependent on active ingredients. Furthermore, the gels enable moisture and oil absorption, heat resistance and a smooth application texture.

Solesphere products are claimed to be safe for both humans and aquatic life. Since the ingredients are made from amorphous silica, they are corrosion-free and safe for the environment and human contact.
Solesphere H-52 has a 10 µm pore diameter and an oil absorption level of 300 mL/g, while Solesphere H-53 has an 11 µm pore diameter and an oil absorption level of 400 mL/g.
