Title (DE) STABILISIERUNG VON PERCARBONAT
(EN) STABILISATION OF PERCARBONATE
(FR) STABILISATION DE PERCARBONATE
Abstract:
(DE) Durch die Verwendung von unter Hydrolysebedingungen Essigsäure abspaltenden Verbindungen, vorzugsweise aus der Gruppe der N- oder O-acetylierten Substanzen, kann pulverförmiges Percarbonat, insbesondere in Bleich-, Wasch-, Reinigungs- und Desinfektionsmitteln, sehr effektiv gegen den Verlust von Aktivsauerstoff stabilisiert werden.
(EN) By the use of compounds separating acetic acid in hydrolysis conditions, preferably from the group of N- or O-acetylised substances, it is possible to stabilise powdered percarbonate very effectively against the loss of active oxygen, especially in bleaching, washing, cleaning and disinfecting agents.
(FR) Par l'utilisation de composés séparant l'acide acétique dans des conditions d'hydrolyse, de préférence d'un groupe des substances N- ou O-acétylés, il est possible de stabiliser du percarbonate pulvérulent, en particulier dans des agents de blanchiment, de nettoyage et de désinfection, très efficacement contre la perte d'oxygène actif.
