Biosanitizer is an ecological, alcohol-free and aldehyde-free disinfectant cleaner concentrate for moulds, dentures, and impression materials. It guarantees dimensional stability of impression materials during prolonged soaking. A hyper-concentrated formula allows it to be diluted up to 200 liters with only 1000g of concentrate, reducing environmental impact. It kills bacteria and viruses with a 5 minute soak at 0.5% dilution, and can be extended to eliminate yeasts and tuberculosis bacteria by increasing concentration and soak time.
