<p>For optimum detergency, particulate detergent compositions built with aluminosilicate (25-45 wt%), and containing an anionic surfactant component (5-35 wt%) consisting of primary alcohol sulphate (PAS) (10-100 wt%) optionally with linear alkylbenzene sulphonate (LAS) (0-90 wt%), contain 0-20 wt% sodium carbonate depending on the relative proportions of PAS and LAS present: 0-10 wt% carbonate for 10-60 wt% PAS/40-90 wt% LAS, 0-20 wt% carbonate for 60-80 wt% PAS/20-40 wt% LAS, and 10-20 wt% carbonate for 80-100 wt% PAS/0-20 wt% LAS.</p> |
