Abstract

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.
