A heavy duty liquid laundry detergent composition having a surfactant system. The surfactant system comprises from about 0.1 % to about 20 %, by weight of the surfactant system of an alkyl benzene sulfonate surfactant, and the surfactant system has a Hydrophilic Index, HIC, of from about 8 to about 9.2. The Hydrophilic Index is calculated as follows: HIC = .SIGMA.y (weight % of surfactant y in the surfactant system) x (HISy), HISy is calculated for each of the surfactants in the surfactant systems as follows: HISy = 20 x (the molecular weight of the hydrophilic portion of surfactant component y)/(the molecular weight of surfactant component y).
La présente invention concerne une composition détergente liquide puissante pour lessives avec système tensioactif. Cette solution comprend de 0,1 % à environ 20 % en poids d'un système tensioactif comprenant un tensioactif à base de sulfonate d'alkyle benzène, et se caractérise par un indice hydrophile HI¿C? compris entre 8 et 9,2 environ. Cet indice se calcule de la manière suivante: HI¿C? = .SIGMA.¿y? (% en poids de tensioactif dans le système tensioactif) x (HI¿Sy?). Pour chacun des tensioactifs contenus dans le système tensioactif, HI¿Sy? se calcule comme suit: HI¿Sy? = 20 x (poids moléculaire de la partie hydrophile de la composante tensioactive y)/(poids moléculaire de la composante tensioactive y).
