Title
(EN) ALKYL TOLUENE SULFONATE DETERGENTS
(FR) DETERGENTS DE SULFONATE D'ALKYLTOLUENE
Abstract
(EN)
This invention is directed to detergent compositions which employ sulfonated alkyltoluenes as surfactants, wherein the sulfonated alkyltoluenes have a higher content of the sulfonated 2-phenyl alkyltoluenes isomers than was previously available in sulfonated alkyltoluene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated alkyltoluenes having lower contents of the 2-phenyl alkyltoluene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkyltoluenes are also provided, including dry cleaning formulations containing same. The alkyltoluenes of this invention may be combined with alkylbenzene surfactants in order to provide detergent blends having increased water hardness tolerance, lower Krafft temperature, and increased cleaning performance over what was previously afforded by the prior art.
(FR)
L'invention concerne des compositions détergentes qui utilisent des alkyltoluènes sulfonés comme agents tensio-actifs, les alkyltoluènes sulfonés présentant une teneur en isomères d'alkyltoluènes 2-phényle sulfonés supérieure à ce qu'on pouvait jusqu'alors trouver dans des tensio-actifs d'alkyltoluènes sulfonés existants. Les compositions de nettoyage selon l'invention sont plus efficaces comme agents nettoyants que leurs homologues déjà existants qui contiennent des alkyltoluènes sulfonés renfermant une plus faible concentration des isomères d'alkyltoluènes 2-phényle, du fait d'une augmentation inattendue de la tolérance à la dureté de l'eau de minéraux normalement associés à une précipation de l'agent détergent actif. L'invention concerne également des sels sulfonés solides d'alkyltoluènes, dont des formulations nettoyantes sèches contenant lesdits sels. Les alkyltoluènes peuvent être combinés à des tensio-actifs d'alkylbenzène pour produire des mélanges détergents présentant une meilleure résistance à la dureté de l'eau, une température de Krafft inférieure et une meilleure performance de nettoyage qu'il n'était jusqu'alors possible.
