Special characteristics

  • High purity: EXCELICA™ is produced in a closed system using highly purified materials, resulting in silica with a trace of impurities such as radioelements, heavy metal elements, or ionic elements. Especially the amount of uranium or thorium contained, which emits alpha rays causing semiconductor memory malfunctions, in EXCELICA™ is less than 0.1ppb.
  • Amorphous: The X-ray diffraction pattern shows that EXCELICA™ is amorphous.

For Cosmetics and Personal care

  • Silky Smooth Skin feel: The narrow and uniformed particle size distribution provides a silky, smooth skin feel.
  • Soft Focus Effect: Reducing the visibility of wrinkles and pores by reducing unevenness.
  • Eco-Friendly: EXCELICA™ can be an alternative to micro plastic beads and is an environmentally friendly material. Its natural origin index is 1. (acc. to ISO 16128)
