CA 2288887

Basic cleaning compositions using toxicologically-acceptable ingredients for cleaning hard surfaces are provided. Compositions safe for use on surfaces which are contacted by food intended for ingestion by humans or lower animals, even when the compositions are incompletely removed from the cleansed surface, are described. Liquid formulations comprising surfactant, such as sodium alkyl sulfate, sodium alkylbenzene sulfonate, etc., and having a pH of above 11.6 are contacted directly onto hard surfaces to remove soil and unwanted deposits. Articles for applying the compositions to hard surfaces by spraying are disclosed.

L'invention porte sur des compositions de nettoyage basiques utilisant des ingrédients acceptables sur le plan toxicologique, ces compositions étant destinées à nettoyer des surfaces dures. Elles ne présentent aucun danger pour être utilisées sur des surfaces qui sont en contact avec des aliments devant être ingérés par l'homme ou l'animal même lorsqu'elles ne sont pas complètement retirées de la surface nettoyée. Des formulations liquides comprenant un tensioactif tel que le sulfate d'alkyle de sodium, le sulfonate d'alkylbenzène de sodium, etc., et ayant un pH supérieur à 11,6, sont directement mises en contact avec des surfaces dures pour retirer les souillures et les dépôts non désirés. Des articles permettant d'appliquer ces compositions par pulvérisation sur des surfaces dures sont également décrits.
