PERISTAL MW conc.

PERISTAL MW conc. is an excellent stabilizer for the peroxide bleach. PERISTAL MW conc. is not surface active and thus absolutely free from foam. PERISTAL MW conc. can be used in the hot as well as in the cold pad batch bleaching. PERISTAL MW conc. is a product which controls the activation of the bleaching agent in peroxide bleaches. Alkali activates peroxide. Due to the different alkaline consumption of the grey materials an activation control is necessary. PERISTAL MW conc. serves this purpose in an excellent manner and keeps the bleach in an optimal pH range. PERISTAL MW conc. prevents catalytic damages in case of heavy metals in ionic form, but not in case of metallic impurities. To destroy these, a preliminary acid treatment is recommended.
