Secondary (2,3) alkyl sulfate surfactants are admixed with powdered detersive ingredients and combined with a surfactant paste. The resulting detergent dough is extruded through an orifice and sized to provide particles. The particles are coated with a free-flow aid. The resulting SAS particles exhibit improved solubility and are especially useful in laundry detergents.
Des tensioactifs secondaires (2,3) alkyle sulfate sont mélangés à des ingrédients détersifs en poudre et combinés à une pâte de tensioactif. La pâte détergeante obtenue est extrudée dans un orifice et transformée en particules. Ces particules sont revêtues d'un support à écoulement libre. Les particules secondaires alkyle sulfate (S, A, S) obtenues présentent une meilleure solubilité et sont notamment utiles dans les détergeants pour blanchissage.
