Abstract (en)
The present invention relates to a solid laundry detergent composition comprising: (a) from 20wt% to 39wt% detersive surfactant selected from anionic detersive surfactant and/or non-ionic detersive surfactant; (b) from 10wt% to 40wt% inorganic salts selected from sodium carbonate, sodium sesquicarbonate, sodium bicarbonate and any mixtures thereof; (c) optionally, from 10wt% to 40wt% citric acid and/or salts thereof; (d) from 0.5wt% to 20wt% alkyl ether carboxylic acid having the following structure: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R-(OCH 2 CH 2 )n-OCH 2 -COOH wherein, R is selected from saturated and mono-unsaturated C 10 to C 26 linear or branched alkyl chains, and n is selected from 5 to 20, wherein at 1wt% dilution in de-ionised water at 20°C, the composition has a pH in the range of from 7.6 to 10.0, wherein at 1wt% dilution in de-ionised water at 20°C, the composition has a reserve alkalinity to pH 7.5 of greater than 3.0, wherein the composition is in the form of a coated laundry detergent particle that is curved and has perpendicular dimensions x, y and z, wherein x is from 0.5mm to 2.0mm, wherein y is from 2.0mm to 8.0mm, and wherein z is from 2.0mm to 8.0mm, wherein the coating comprises the inorganic salt (b), and wherein the core comprises the detersive surfactant (a).
