Title (EN) CLEANING, LAUNDERING OR TREATING COMPOSITIONS CONTAINING CROSS-LINKED HYDROLASE CRYSTALS
(FR) COMPOSITIONS DE NETTOYAGE, DE BLANCHISSAGE OU DE TRAITEMENT CONTENANT DES CRISTAUX D'HYDROLASE
Abstract:
(EN) The present invention provides a product and method for cleaning or laundering or treatment of fabrics or surfaces, with a liquid cleaning, laundering or treating composition having improved enzyme stability in the presence of an oxidant comprising a) at least one cross-linked hydrolase crystal, or mixture of hydrolase crystals; b) an oxidant, or source of hydrogen peroxide; and c) at least one cleaning, laundering or treating additive, other than an oxidant, wherein the improved stability is due to one or more of the following: (i) where c) includes a surfactant, maintaining the upper limit thereof to no greater than 10 % by weight of the composition; (ii) maintaining the pH of the liquid composition between 5 and 8; and (iii) where c) includes surfactants, no more than 20 % of the total surfactants is anionic. The use of the cross-linked hydrolase crystals results in compositions which have surprisingly proficient retained hydrolytic stability in the presence of such oxidant versus a commercially available non-cross-linked enzyme.
(FR) L'invention concerne un produit et un procédé de nettoyage, de blanchissage ou de traitement de tissus ou de surfaces, au moyen d'une composition liquide de nettoyage, de blanchissage ou de traitement possédant une stabilité des enzymes améliorée en présence d'un oxydant. La composition renferme a) au moins un cristal d'hydrolase réticulé ou un mélange de cristaux d'hydrolase, b) un oxydant ou une source de peroxyde d'hydrogène et c) au moins un additif de nettoyage, de blanchissage ou de traitement, autre qu'un oxydant. La stabilité améliorée est dûe à un ou plusieurs des facteurs suivants : (i) si c) comporte un agent de surface, la limite supérieure de ce dernier est maintenue à un maximum de 10 % en poids de la composition, (ii) le pH de la composition liquide est maintenu entre 5 et 8, et (iii) si c) comporte des agents de surface, 20 % au plus de la quantité totale des agents de surfaces sont anioniques. L'utilisation de cristaux d'hydrolase réticulés produit des compositions possédant une stabilité hydrolytique maintenue étonnamment efficace en présence dudit oxydant, contrairement à une enzyme non réticulée disponible dans le commerce.
