Patent

CA 2663360

The present invention relates to a solid laundry detergent composition having a bulk density of from lOOg/1 to 500g/l, wherein the composition comprises: (a) from lwt% to 70wt% anionic detersive surfactant; (b) from Owt% to 10wt% zeolite builder; and (c) from Owt% to 10wt% phosphate builder; wherein the composition comprises: (I) from 61wt% to 90wt% low- density particulate component, wherein the low-density particulate component has a bulk density of from lOOg/1 to 426g/l, and wherein the low-density particulate component comprises inorganic material and organic material; and (II) from 10wt% to 39wt% high-density particulate component, wherein the high-density particulate component has a bulk density of greater than 426g/l; wherein the ratio of (i) the weight ratio of the inorganic material to the organic material comprised in the low-density particulate component (I) to (ii) the weight ratio of the inorganic material to the organic material comprised in the solid laundry detergent composition is from 0.3: 1 to 5: 1.

La présente invention concerne une composition détergente solide pour lessive, ayant une densité apparente allant de 100 g/l à 500 g/l, la composition comprenant : (a) de 1 % en poids à 70 % en poids d'un tensioactif détersif anionique ; (b) de 0 % en poids à 10 % en poids d'un adjuvant zéolite ; et (c) de 0 % en poids à 10 % en poids d'un adjuvant phosphate ; la composition comprenant : (I) de 61 % en poids à 90 % en poids d'un composant particulaire de faible densité, le composant particulaire de faible densité ayant une densité apparente allant de 100 g/l à 426 g/l, et le composant particulaire de faible densité comprenant un matériau inorganique et un matériau organique ; et (II) de 10 % en poids à 39 % en poids d'un composant particulaire de densité élevée, le composant particulaire de densité élevée ayant une densité apparente supérieure à 426 g/l ; le rapport du (i) rapport massique du matériau inorganique sur le matériau organique compris dans le composant particulaire de faible densité (I) sur (ii) le rapport massique du matériau inorganique sur le matériau organique compris dans la composition détergente solide pour lessive allant de 0,3 : 1 à 5 : 1.
