Process for making granular detergents |
摘要 |
<p>The invention provides an aqueous slurry which comprises anionic surfactant and aluminosilicate, and at the same time has a low viscosity suitable for spray-drying to form crisp, free-flowing powder. The aqueous slurry further comprises less than 5% by weight of silicate and at least 1% by weight of an inorganic salt, or a mixture of inorganic salts, whereby the addition of the inorganic salt increases the ionic conductivity of the aqueous slurry. The slurry is subsequently dried to form a particulate detergent composition.</p> |
