Detergent softener with amine ingredient

Claim 1

A method of preparing a detergent composition adapted to provide fabric softening benefits when used to wash textiles, said method constituting the steps of (a) forming a slurry containing (i) an anionic surfactant selected from the group consisting of sodium and potassium C 9 -C 15 alkyl benzene sulphonates, C 12 -C 18 alkyl sulphates and C 12 -C 18 alkyl polyethoxy ether sulphates containing from about 1 to about 12 ethoxy groups per mole and mixtures thereof, said anionic surfactant being present in an amount to provide from about 3% to about 30% of the composition, (ii) a water soluble alkaline detergency builder salt selected from the group consisting of alkaline sodium and potassium carbonates, borates, phosphates, polyphosphates, silicates, polycarboxylates, polyphosphonates, amino polycarboxylates, amino polymethylene phosphonates and mixtures thereof, said detergency builder salt being present in an amount to provide from about 10% to about 80% of the composition, (b) spray during said slurry so as to form free-flowing spray dried granules and (c) spraying said spray dried granules with a tertiary amine in liquid form in an amount of from about 1% to about 25% by weight of the composition, said amine being selected from the group consisting of (i) alkylamines of formula ##STR9## wherein R 1 and R 2 are each radicals independently selected from C 10 -C 26 alkyl and alkenyl groups and R 3 represents a radical selected from the group consisting of ##STR10## wherein R 4 is a C 1 -C 4 alkyl group, each R 5 is independently selected from H and C 1 -C 4 alkyl groups and each R 6 is independently selected from H and C 1 -C 20 alkyl groups and (ii) imidazoline derivatives of formula ##STR11## wherein R 1 and R 2 are as defined above and (iii) mixtures of any of (i) and (ii). (d) dry mixing oxygen bleaching agent or enzyme or silica/silicone suds suppressor or mixtures thereof with the product of step (c).

Claim 2

A method of preparing a detergent composition adapted to provide fabric softening benefits when used to wash textiles, said method constituting the steps of (a) forming a slurry containing (i) an anionic surfactant selected from the group consisting of sodium and potassium C 9 -C 15 alkyl benzene sulphonates, C 12 -C 18 alkyl sulphates and C 12 -C 18 alkyl polyethoxy ether sulphates containing from about 1 to about 12 ethoxy groups per mole and mixtures thereof, said anionic surfactant being present in an amount to provide from about 3% to about 30% of the composition, (ii) a water soluble alkaline detergency builder salt selected from the group consisting of alkaline sodium and potassium carbonates, borates, phosphates, polyphosphates, silicates, polycarboxylates, polyphosphonates, amino polycarboxylates, amino polymethylene phosphonates and mixtures thereof, said detergency builder salt being present in an amount to provide from about 10% to about 80% of the composition, (b) spray during said slurry so as to form free-flowing spray dried granules and (c) spraying said spray dried granules with a tertiary amine in liquid form in an amount of from about 1% to about 25% by weight of the composition, said amine being selected from the group consisting of (i) alkylamines of formula ##STR9## wherein R 1 and R 2 are each radicals independently selected from C 10 -C 26 alkyl and alkenyl groups and R 3 represents a radical selected from the group consisting of ##STR10## wherein R 4 is a C 1 -C 4 alkyl group, each R 5 is independently selected from H and C 1 -C 4 alkyl groups and each R 6 is independently selected from H and C 1 -C 20 alkyl groups and (ii) imidazoline derivatives of formula ##STR11## wherein R 1 and R 2 are as defined above and (iii) mixtures of any of (i) and (ii). (d) dry mixing oxygen bleaching agent or enzyme or silica/silicone suds suppressor or mixtures thereof with the product of step (c).
