Imidazole-modified carbohydrate polymers as laundry dye transfer inhibitors
View Patent ↗A laundry detergent comprising: (a) from 10 to 86 wt % surfactants, (b) from 0.05 to 2 wt % imidazole-modified carbohydrate polymer, (c) from 0.1 to 10 wt % builders and sequestrants and (d) from 2 to 88 wt % water.
1. A liquid laundry detergent comprising: (a) from 10 to 86 wt % surfactants, (b) from 0.05 to 2 wt % imidazole-modified carbohydrate polymer comprising an alkylation product of hydroxyethylcellulose and either imidazole having an epoxyalkyl substituent or imidazole having a vicinal halohydroxy group, (c) from 0.1 to 10 wt % builders and sequestrants and (d) from 2 to 88 wt % water.
2. The liquid laundry detergent of claim 1 having from 0.1 to 1.2 wt % imidazole-modified carbohydrate polymer.
3. A method for inhibiting dye transfer in a washing machine; said process comprising adding to the washing machine a laundry detergent comprising: (a) from 10 to 86 wt % surfactants, (b) from 0.05 to 2 wt % imidazole-modified carbohydrate polymer comprising an alkylation product of hydroxyethylcellulose and either imidazole having an epoxyalkyl substituent or imidazole having a vicinal halohydroxy group, (c) from 0.1 to 10 wt % builders and sequestrants and (d) from 2 to 88 wt % water.
4. The method of claim 3 having from 0.1 to 1.2 wt % imidazole-modified carbohydrate polymer.
5. The liquid laundry detergent of claim 2 in which the imidazole having an epoxyalkyl substituent is 1-glycidylimidazole and the imidazole having a vicinal halohydroxy group is 3-chloro-2-hydroxypropyl imidazole.
6. The method of claim 4 in which the imidazole having an epoxyalkyl substituent is 1-glycidylimidazole and the imidazole having a vicinal halohydroxy group is 3-chloro-2-hydroxypropyl imidazole.
