CA 2299292

The present invention relates to an aqueous, liquid hard surface detergent composition having excellent surface lubricity and filming/streaking characteristics. Said composition comprises less than about 1 %, by weight of the composition, of surfactant to provide lubricity, preferably straight chain alkyl sulfate wherein at least about 30 %, preferably wherein more than about 50 %, of said surfactant, by weight, has a C12 or C14 chain length or mixtures thereof, hydrophobic cleaning solvent; an optional substantive material that increases the hydrophilicity of the glass; and preferred low level of alkaline buffering agent to provide composition stability on storage and alkalinity, without diminishing the lubricity.

La présente invention concerne une composition détergente aqueuse, liquide, destinée aux surfaces dures, possédant un excellent pouvoir lubrifiant de ces surfaces ainsi que d'excellentes caractéristiques de dépôt d'un film hydrophobe et anti-tâches. Cette composition comprend moins de 1 % environ en poids, du poids de la composition, d'un tensioactif servant de lubrifiant, de préférence un sulfate d'alkyle à chaîne droite dans lequel 30 % environ, de préférence plus de 50 % environ en poids de ce tensioactif possèdent une longueur de chaîne C12 ou C14, ou bien la composition comprend des mélanges de ces substances; elle comprend également un solvant de nettoyage hydrophobe, éventuellement une matière substantive augmentant l'hydrophilie du verre, ainsi que préférablement une faible quantité d'un tampon alcalin, afin de rendre la composition stable lors de son stockage et de la doter d'une certaine alcalinité, sans lui ôter son pouvoir lubrifiant.
