Abstract
A process for making detergent agglomerates in which a high active surfactant paste containing mid-chain branched alkyl sulfate surfactant and a detergent builder are agglomerated together is disclosed. The process entails maintaining the high active surfactant paste in highly stable, pumpable and transportable form over an extended period of time. In this way the process facilitates multi-locational, large-scale manufacture of modern compact detergent products. In particular, the high active surfactant paste can be manufactured in one facility, and thereafter, stored and transported to a remote facility for further processing in to the finished detergent agglomerates.
