Abstract
A cleaning composition, preferably a granular laundry detergent composition, containing a diaminostilbene brightener in a surfactant system containing a C10-C20 linear alkylbenzene sulphonate (LAS), a C6-C18 unalkoxylated alkyl sulphate (AS), and fatty acids or salts thereof at specific amounts and weight ratios. Such a surfactant system results in surprisingly better dissolution of the diaminostilbene brightener in water.
Claims12
A cleaning composition comprising:
- a) from 6 wt % to 15 wt % of a C10-C20 linear alkylbenzene sulphonate (LAS);
- b) from 0.3 wt % to 4 wt % of an alkyl sulphate (AS) having a branched or linear unalkoxylated alkyl group comprising from 6 to 18 carbon atoms, wherein the LAS-to-AS weight ratio is from 3:1 to 30:1;
- c) from 1.5 wt % to 6 wt % of one or more fatty acids or salts thereof;
- and
- d) from 0.01 wt % to 1 wt % of a diaminostilbene brightener.

3 more elements
A concentrated granular laundry detergent composition comprising:
- a) from 12 wt % to 30 wt % of a C12 linear alkylbenzene sulphonate (LAS);
- b) from 0.5 wt % to 8 wt % of an alkyl sulphate (AS) having a branched or linear unalkoxylated alkyl group comprising from 12 to 14 carbon atoms, wherein the LAS-to-AS weight ratio is from 3:1 to 30:1;
- c) from 4 wt % to 12 wt % of one or more saturated fatty acids or salts thereof comprising from 12 to 18 carbon atoms;
- and
- d) from 0.05 wt % to 2 wt % of disodium 4,4′-bis{[4-anilino-6-morpholino-s-triazin-2-yl]-amino}-2,2′-stilbenedisulfonate,
