Packaging Requirements:
10 kg paper bag with proper labeling. The paper bag is covered with “OMNISCIENT” printed polythene bag.
TAMC (total aerobic microbial count) , TYMC (total combined yeast and mould count) and Gram-negative bacteria are tested on a regular basis acc. to USP <61> and USP <62>.
Manufactured and packaged in a dedicated closed production system according to ISO 9001 : 2015.
White, fine, amorphous powder.
Typical sieve residue (Grit, 45 μm) is < 0.025 % (according to ISO787-18).
Residual solvents:
No organic solvents are used in the manufacture of above mentioned product. For this reason, constitutionally no residual solvents as cited in recent versions of the European Pharmacopoeia, (class 1, 2 and 3 or other solvents, USP chapter 467), 2008 and amendments are present in concentration about the control limits quoted in USP. For above mentioned product class 1 residual solvents are tested on a regular basis according to USP/NF: Carbon tetrachloride, 1,2 Dichlorethane, 1,1Dichlorethene, 1,1,1 Trichlorethane and Benzene.
TSE/BSE and materials of plant origin:
No raw materials of animal or plant origin (as mentioned in EMEA/410/01, current version) are used in the production process of OMNISILTM 200P. OMNISILTM 200P have not been in contact with and constitutionally do not include any material of animal or plant origin. We generally do not use any material of animal or plant origin in our production facilities. OMNISILTM 200P are not contaminated with material of animal or plant origin when they leave our production and warehouses.
Industrial Applications
Food, Feed and Cosmetics
As a food additive, it serves as an anticaking agent to avoid clumping. In supplements, food- grade fumed silica is an effective thickening, emulsification, gelling and anti-settling agent, due to its ability to form a network and hold heavier ingredients in place.
OMNISILTM 200 is suggested for use in skin care,oral care, hair care (beaches, dyes, conditioners), make-up (powder, nail polish, lipstick/lip gloss) and antiperspirants & deodorants (sticks) applications.
