8. A detergent composition as claimed in claim 1 , wherein the granules further comprise a polymeric binder.
9. A detergent composition as claimed in claim 1 , wherein the granules are present in the composition in an amount of from 1 to 3 wt %.
10. A detergent composition as claimed in claim 1 , wherein the surfactant comprises an anionic sulphonate or sulphate surfactant and an ethoxylated nonionic surfactant in a weight ratio not exceeding 2:1, preferably not exceeding 1.5:1.
11. A detergent composition as claimed in claim 1 , wherein the surfactant comprises one or more surfactants mild to the skin.
12. A detergent composition as claimed in claim 11 , wherein the surfactant comprises one or more surfactants selected from alkylpolyglycosides and highly ethoxylated alcohol nonionic surfactants having an average degree of ethoxylation of from 15 to 40, preferably from 15 to 30.
13. A detergent composition as claimed in claim 1 , which is free of enzymes.
14. A detergent composition as claimed in claim 1 , which contains clay particles in addition to that which is acting as carrier.
15. A detergent composition as claimed in claim 1 , which is a built particulate detergent composition in powder or tablet form comprising:
(a) from 5 to 40 wt % of organic detergent surfactant,
(b) from 10 to 80 wt % of detergency builder,
(c) from 0.5 to 5 wt %, preferably from 1 to 3 wt %, of coloured granules comprising aloe vera and a clay carrier, the granules providing from 0.0001 to 0.0050 wt %, preferably from 0.0005 to 0.0010 wt %, of aloe vera based on a 100 wt % dry matter basis.
16. A built particulate detergent composition as claimed in claim 15 , which comprises:
(i) from 5 to 25 wt % of an anionic sulphonate or sulphate surfactant,
(ii) from 1 to 10 wt % of an ethoxylated alcohol nonionic surfactant,
(iii) from 0.5 to 5 wt % of alkylpolyglycoside,
(iv) from 10 to 80 wt % of detergency builder and
(v) from 0.5 to 5 wt %, preferably from 1 to 3 wt %, of coloured granules comprising aloe vera and a clay carrier, the granules providing from 0.0001 to 0.0050 wt %, preferably from 0.0005 to 0.0010 wt %, of aloe vera based on a 100 wt % dry matter basis,
(vi) optionally other detergent ingredients to 100 wt %.
17. A built particulate laundry detergent composition as claimed in claim 15 , which comprises:
(i) from 5 to 25 wt % of an anionic sulphonate or sulphate surfactant,
(ii) from 1 to 10 wt % of an ethoxylated alcohol nonionic surfactant having an alkyl chain length of from C 8 to C 18 and an average degree of ethoxylation of from 3 to 10,
(iii) from 1 to 5 wt % of a highly ethoxylated alcohol nonionic surfactant having an average degree of ethoxylation of from 15 to 40,
(iv) from 10 to 80 wt % of detergency builder and
(v) from 0.5 to 5 wt %, preferably from 1 to 3 wt %, of coloured granules comprising aloe vera and the clay carrier material, the granules providing from 0.0001 to 0.0050 wt %, preferably from 0.0005 to 0.0010 wt %, of aloe vera based on a 100 wt % dry matter basis,
(vi) optionally other detergent ingredients to 100 wt %.
