Abstract
A fabric softening particle is provided comprising a mixture of quaternary ammonium ion-exchanged clay having an ion-exchange capacity of at least about 10 meq/100 gms and preferably about 50 meq/100 gms and a water-insoluble quaternary ammonium salt in the ratio of 1:3 to 3:1. The particle softens more efficiently than either of its components. When incorporated into a detergent powder, detergency is not diminished as would occur when either of the particle components are separately incorporated.
