Improved hard surface cleaning compositions having an acidic pH provide good removal of soap scum stains, and further feature low levels of irritability to the user. The compositions comprise 0.1-10 % by weight of an acid sequestrant constituent; 0.1-10 % by weight of a mixture of hydrophobic and hydrophilic solvents; 1-8 % by weight of a surfactant and/or hydrotrope constituent; 0-20 % by weight of one or more optional constituents; the balance to 100 % by weight of water, wherein the aqueous hard surface cleaning composition exhibits a pH of 7.0 or less, especially a pH of 5.0 and less. Although acidic, the improved hard surface cleaning compositions feature low irritability to the eyes and skin of consumers. The compositions also provide disinfecting effects. Processes for the production of the said compositions, as well as methods for their use are also described.
L'invention porte sur une composition améliorée de nettoyage de surfaces dures, à pH acide et assurant une bonne élimination des taches de mousse de savon et peu irritante pour l'utilisateur. Elle comporte en poids: 0,1 à 10 % d'un séquestrant d'acide 0,1 à 10 % d'un mélange de solvants hydrophobes et hydrophiles; 1 à 8 % d'un tensioactif et/ou d'un hydrotrope; 0 à 20 % d'un ou de plusieurs constituants facultatifs; et le reste d'eau. La composition de nettoyage de surfaces dures qui présente un pH de 7 ou moins, de préférence de 5 ou moins, n'est, malgré son acidité, que peu irritante pour les yeux ou la peau de l'utilisateur et elle possède en outre un pouvoir désinfectant. L'invention porte également sur les procédés de fabrication et les méthodes d'utilisation desdites compositions.
