 ? Properties: an anion, the appearance of a very light yellow powder. Colors for glaucoma, the fluorescence intensity (with the standard ratio) 100. Sun-resistant, resistant to sulfite, hydrogen peroxide; case of sodium hypochlorite unstable 
 Compared with similar products is the most stable. This product does not damage the skin, slightly toxic. With anionic, nonionic surfactant and silicate, sodium, sulfate, soda ash, CMC, good compatibility and other enzymes. When combined with anionic, nonionic surfactant compatibility, you can create synergies and improve the whitening effect; and anion compatibility, it can produce brightening effect; but not with cationic dyes, cationic additives mixed with the bath. This product has a whitening effect is good, yellow point is low, resistance to oxygen bleaching, is the high-end washing powder, soap, textile, paper, latex paint with a brightener.
