  • Process for conditioning of surfactant pastes to form high active surfactant agglomerates
    Patent number: 6172033
    Abstract: A process for conditioning pastes comprising at least 40% by weight of anionic surfactant is provided. 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.
