The present invention provides a process for making a granular laundry detergent component or composition having a bulk density of at least 650 g/l comprising the steps of: a) dissolving a structuring agent in a nonionic surfactant to form a pumpable premix, wherein the structuring agent comprises a glyceride, and wherein the nonionic surfactant comprises polyhydroxy fatty acid amide at a level of at least 3 % (by weight of the component or composition); b) granulating said premix. Granular laundry compositions and components comprising polyhydroxy fatty acid amide and glyceride fats are also disclosed.
L'invention concerne un procédé qui permet de produire un élément ou une composition de détergent granulaire pour textiles qui présente une masse volumique en vrac d'au moins 650 g/l. Ce procédé consiste: a) à dissoudre un agent structurant dans un agent tensioactif non ionique pour constituer un prémélange susceptible d'être pompé, l'agent structurant comprenant un glycéride et l'agent tensioactif non ionique comprenant un amide d'acide gras polyhydroxy à raison d'au moins 3 % (en poids de l'élément ou de la composition); b) à granuler ce prémélange. On décrit aussi des compositions et des éléments granulaires de détergents textiles qui comprennent des amides d'acides gras polyhydroxy et des glycérides.
