Officina Naturae Whitening Percarbonate, thanks to its exclusive formula enriched with Silicates and Phosphonates, softens the water, thus improving washing effectiveness and allowing for a reduction in the amount of detergent used. To clarify any doubts you may have, we'll explain the difference between Pure Sodium Percarbonate and Officina Naturae Whitening Percarbonate. . Pure sodium percarbonate is a solid chemical compound that contains active oxygen and is used as a bleach and disinfectant. This Whitening Percarbonate, on the other hand, is an exclusive formula that contains Sodium Percarbonate as an active ingredient along with other additives to improve its effectiveness in removing stains and whitening fabrics. . This formulation, in fact, limits one of the problems arising from the use of pure Sodium Percarbonate alone: during its action, Sodium Percarbonate (not to be confused with Perborate) creates Sodium Carbonate salts, which, depositing on the texture of the garments, tend to harden them and make them unpleasant to the skin. . The inclusion of sequestrants in the formula therefore leaves garments softer and more pleasant. . Thanks to the sequestrants used, Bleaching Percarbonate has a high stability over time. Sodium Percarbonate alone, on the other hand, tends to lose effectiveness over time, due to the continuous release of oxygen. . The sequestrants we use are perfectly soluble and do not create problems for the environment or drains, unlike zeolites, which are a commonly used ingredient in detergents to soften water but are completely insoluble and the main cause of white crusts in drainpipes. Sodium Percarbonate Bleaching Agent is particularly suitable for washing washable sanitary towels and diapers. . Sanitizing action for laundry, dishes and commonly used accessories. . Sanitizes, whitens and removes stains already at 40°C. . Contains no: enzymes, perfumes or optical brighteners.
