Bleaching up to 7 tones. The powder has other persulfates in the composition than Ultrablond, and a kaolin component. Kaolin gives a more pasty powder texture like clay and makes it perfect for working in open techniques. There are 3 types of persulfate in the powder; their concentration in the composition is less than in Ultrablond. Therefore, the powder works longer and copes better with the cosmetic base. The mixture remains stable, does not swell and does not flow during the decoloration process.
