Abstract
A particulate composition for softening textile fabrics in the wash comprises: (a) from 5 to 30% by weight of a primary, secondary or tertiary amine capable of softening fabrics, sorbed onto (b) from 70 to 95% by weight of a particulate carrier comprising a porous crystal-growth-modified carbonate-based salt. The preferred particulate carrier is the sodium carbonate/sodium sulphate double salt Burkeite modified by means of a polymeric polycarboxylate. The softening composition may be incorporated in a detergent powder, suitably in an amount providing from 0.5 to 15% by weight of amine in the total powder.
