Secondary (2, 3) alkyl sulfate surfactants are admixed with an organic material such as a polyacrylate, and the resulting mixture is compacted into chips. The chips are comminuted to provide particles, and the particles are coated with a free-flow aid. The resulting SAS particles exhibit improved solubility and are especially useful in laundry detergents.
Cette invention concerne des tensioactifs à base sulfate (2, 3) alkyle secondaire (SAS), auxquels on ajoute une matière organique, tel que du polyacrylate, de manière à obtenir un mélange qui est ensuite compacté en copeaux. Ces copeaux sont ensuite finement broyés en particules, après quoi lesdites particules sont enduites d'un agent facilitant leur écoulement fluide. Les particules de SAS ainsi obtenues possèdent une meilleure solubilité et sont particulièrement utiles en qualité de détergents blanchissants.
