Abstract
The present invention relates to detergent compositions which comprise a flocculating agent and an organophilic smectite clay whereof at least 30%, preferably at least 40% of the exchangeable cations in the clay is replaced by one or more long-chain organic cations, preferably having at least one long carbon chain of at least 10 or even 12 carbon atoms. The compositions provide improved fabric softening and deliver good cleaning.
