    Abstract: The present invention relates to a coated detergent particle having a distorted oblate spheroidal shape with perpendicular dimensions x, y and z, wherein x is from 1 to 2 mm, y is from 2 to 8mm, and z is from 2 to 8 mm, wherein the particle comprises: (a) from 20wt% to 59wt% 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; wherein the detersive surfactant comprises from 51wt% to 100wt% alkyl benzene sulphonate, wherein the coating comprises the inorganic salt (b), and wherein the core comprises the detersive surfactant (a), wherein the oblate spheroidal shape is distorted such that the ratio of the surface area (S) to volume (V) of the particle is different to the value of NL, Formula (I) wherein NL is defined as: Formula (II) wherein a = is half of the greater of y or z (long radius of the oblate) b = half of the dimension x (short radius of the oblate) ε = the eccentricity, wherein Formula (III)

    Abstract: The present invention relates to a cleaning composition comprising: (a) linear alkyl benzene sulphonate surfactant; (b) alkyl ethoxylated sulphate surfactant; (c) alkoxylated polymer comprising a core structure selected from: (i). linear oligoamine represented by structure below, wherein each L is independently -(CmH2m)- wherein the index m is an integer from 2 to 6;L is independently selected from a C2-C6 alkyl, and wherein the index n is an integer of from 0 to 10; (ii) sugar alcohol comprising at least 4 hydroxy moieties; and (iii) cyclic amine represented by structure below: wherein R1-R6 are independently selected from H, -NH2, -(C1-C4)NH2, linear or branched alkyl or alkenyl having from 1 to 10 carbon atoms, wherein at least two of R1-R6 are selected from -NH2 and -(C1-C4)NH2 or combination, and wherein the index n is an integer of from 0 to 3; wherein at least one of the active H in -OH, -NH- and/or -NH2 moieties of the polymer core is modified with an alkylene oxide moiety selected from ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO) and mixtures thereof, wherein EO/PO/BO alkylene oxide moiety substituents are arranged randomly or in block configuration, and wherein the average number of EO (x), average number of PO (y), and average number of BO (z) per active H in -OH, -NH- and/or -NH2 moieties of the polymer core structure are determined by the following: (a) when the polymer core structure is linear oligoamine according to formula (i), then y + z is more than 2, and the ratio of (y+z) / x is from 51:49 to 100: 0; (b) when the polymer core structure is a sugar alcohol according to formula (ii), then y is from 6 to 50, and the ratio of (y+z) / x is from 51:49 to 100:0; and (c) when the polymer core structure is a cyclic amine according to formula (iii), then y is from 1 to 50, and x and z are from 0 to 50.
