The present invention provides laundry pre-spotter compositions with super or cleaning efficacy using associative polymeric thickeners to synergistically boost cleaning. Cleaning efficacy equivalent to compositions comprising having twice the amount of a nonionic surfactant by weight and a viscosity from about 300 cps to about 100,000 cps at 25°C and 60 RPM is obtained by employing a composition comprising from about 7.0 or 9.0 % to about 13.0 % by weight of at least one nonionic surfactant having an average HLB of from about 8 to about 13 and about 0.25 % to about 2.0 % by weight of at least one associative polymeric thickener.
La présente invention se rapporte à des compositions pré-détachantes pour lessives conférant une meilleure efficacité de lavage au moyen d'épaississants polymères associés afin d'améliorer le nettoyage par effet synergique. On obtient une efficacité de lavage équivalente à des compositions comprenant deux fois la quantité en poids d'un tensioactif non ionique et une viscosité d'environ 300 cps à environ 100 000 cps à 25 ~C et 60 tr/min en utilisant une composition comprenant environ 7 ou 9 % à environ 13 % en poids d'au moins un tensioactif non ionique ayant un rapport hydrophile-lipophile d'environ 8 à environ 13, et environ 0,25 % à environ 2 % en poids d'au moins un épaississant polymère associé.
