Oxyfresh Powder is a fully formulated oxygen release bleaching powder. The active ingredient is sodium percarbonate which releases active oxygen in-situ into the laundry wash solution. Oxyfresh Powder contains activating ingredients which makes it effective at wash temperatures as low as 40°C, although its maximum efficiency is achieved at 60 to 70°C. Oxyfresh Powder is much less aggressive a bleach than conventional hypochlorite-based bleach and causes much less degradation to textiles and dyes. It can be used with white and coloured fabrics.
