摘要

Process for obtaining cold efficacy bleaching agents, especially washing agents with cold whitening efficacy, characterized in that a powder generally obtained by hot spraying of the usual components of bleaching agents or washing agents with bleaching effect, with a water content of approximately 2 to a maximum of 3% by weight, especially with a content of alkaline silicates of the composition Me2O: SiO2 = 1 to 2: 1 (Sesquisilicates) are mechanically mixed with a compound N-acylic or O-acyl, which serves as an activator for H2O2 or a supplier of percomposites in aqueous H2O2 solution, the activator-sesquisilicate system amounting to 3 to 100, preferably 10 to 80% by weight of the total agent, and in up to 20% by weight with the usual additives used in bleaching baths for percomposites, such as, for example, stabilizers, complexing agents and prot agents ectors against corrosion, preferably in molten form.
