Definitions

  • the present invention relates to a composition and a method for treating substrates, such as fabrics; particularly for stain removal across all kinds of stains.
  • Fabric stains run the gamut from food spills to household substances and can be of different types; mainly aqueous, oily, particulate and bleachable. Stains are something that people try to avoid, yet they are unavoidable. Nonetheless, people still prefer to wear clothes with fewer stains or no stains at all. In fact, people prefer to avoid stains not just on clothes but in general in kitchens, bathrooms and also on various household surfaces.
  • WO98/00498 A1 discloses liquid cleaning compositions and shampoos based on a dianionic surfactant in combination with one or more co- surfactants.
  • the dianionic surfactant might be alkoxylated, having at least five carbon atoms to which two anionic substituent groups separated by at least three carbon atoms are attached. Also, amongst the two anionic substituents, one group is a sulfate or an alkoxy- linked sulfate and the other anionic substituent can be either sulfate or sulfonate.

Abstract

La présente invention concerne une composition et un procédé de traitement de substrats, tels que des tissus ; particulièrement pour l'élimination de taches parmi tous les types de taches. Un produit unique qui fonctionne sur tous les différents types de taches est toujours souhaité. Un objet de la présente invention est de fournir une composition pour l'élimination de taches aqueuses/aptes à être blanchies, huileuses, particulaires et enzymatiques. De manière surprenante, il a été découvert que l'élimination de taches aqueuses/aptes à être blanchies, huileuses, particulaires et enzymatiques d'un tissu peut être atteinte grâce à une composition comprenant un système tensioactif de tensioactifs anioniques et bianioniques, le tensioactif anionique étant sélectionné dans le groupe des sulfates alcoxylés d'alkyle et ledit tensioactif bianionique étant choisi dans le groupe du disulfonate d'oxyde de diphényle présentant une longueur de chaîne de carbone s'étendant de C6 à C18, une huile de solubilisation des matières grasses et du peroxyde d'hydrogène.
