The invention provides an effective process for conditioning pastes comprising at least 40 % by weight of anionic surfactant. The paste is conditioned by mixing alkyl sulphate powder with the surfactant paste in a ratio of at least 1 part powder to 100 parts paste. This conditioning step increases the viscosity of the surfactant paste. The conditioned paste is processed into agglomerates by granulating with builder powders wherein the ratio of high viscosity paste to builder powder is from 9:1 to 1:5. This process enables detergent agglomerates with high surfactant activity to be formed.
L'invention concerne un procédé efficace de conditionnement d'une pâte comprenant au moins 40 % en poids d'un tensioactif anionique. La pâte est conditionnée par mélange d'une poudre d'alkyle sulfate avec la pâte tensioactive dans un rapport d'au moins une partie de poudre pour 100 parties de pâte. Cette étape de conditionnement augmente la viscosité de la pâte tensioactive. La pâte conditionnée est traitée en agglomérat par granulation de poudres adjuvantes où le rapport entre la pâte de haute viscosité et la poudre adjuvante est compris entre 9:1 et 1:5. Ce procédé permet de former des agglomérats détergents ayant une forte activité de tensioactif.
