RESIFA™ SOLESPHERE™ Microspheres

SOLESPHERE particles are made from natural, highly pure silicon dioxide. They are microspherical, porous, environmentally safe additives that can enhance the performance of cosmetics and skincare products.

The FDA restricts the loading levels of organic and inorganic UV actives in sunscreen formulations. This can make it difficult for formulators to achieve an SPF 15 rating or higher and claim broad spectrum effectiveness. However, adding 1-2.5% SOLESPHERE silica to sunscreen formulations makes it possible to:

  • Boost SPF to the required level
  • Reduce UV actives while still meeting the desired SPF rating
  • Improve the spreadability of inorganic formulations that use titanium dioxide and/or zinc oxide
  • Make inorganic formulations incorporate better into the skin
  • Reduce the white appearance of inorganic formulations
  • Reduce the UV actives in formulations to reduce skin irritation and promote skin tolerance
  • Resistant to highly reactive organic and inorganic chemicals
  • Excellent volume resistivity (greater than 1016Ω cm)
  • Radiation resistance up to 200 MRad of gamma-ray radiation
  • Unaffected by extended exposure to 200 °C steam
  • Continuous use at 230 °C
  • Resistant to highly reactive organic and inorganic chemicals
  • FDA-compliant for food contact
