RN: 61790-53-2
UNII: 2RF6EJ0M85

Notes

  • A form of SILICON DIOXIDE composed of skeletons of prehistoric aquatic plants which is used for its ABSORPTION quality, taking up 1.5-4 times its weight in water. The microscopic sharp edges are useful for insect control but can also be an inhalation hazard. It has been used in baked goods and animal feed. Kieselguhr is German for flint + earthy sediment.
  • TSCA Definition 2018: A soft siliceous solid composed of skeletons of small prehistoric aquatic plants. Contains primarily silica.
