Abstract: A process for the production of detergent particles, comprises feeding an acid precursor of an anionic surfactant and a neutralising agent into a horizontal thin-film evaporator/drier comprising a mixing region, a drying region and a cooling region. The resultant detergent particles are graded to separate an oversize granule fraction in which at least 70 wt % of the particles have a minimum diameter of 1000 &mgr;m. This fraction is fed back into the process.

Abstract: The invention provides a fabric softening composition comprising;
(i) one or more cationic fabric softening compound(s) having two or more alkyl or alkenyl chains each having an average chain length equal to, or greater than, C8, and
(iv) at least one oily sugar derivative which is a liquid or soft solid derivative of a cyclic polyol or of a reduced saccharide, said derivative resulting from 35 to 100% of the hydroxyl groups in said polyol or in said saccharide being esterified or etherified, and wherein, the derivative has two or more ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain, and
(v) a deposition aid comprising a mixture of one or more nonionic surfactant(s), and one or more one cationic polymer(s),
and wherein the weight ratio of the nonionic surfactant to the cationic polymer is in the range 10:1 to 1:10.
The invention also provides a method of treating fabric with the above compositions.

Abstract: A process for the production of detergent particles comprises feeding an acid precursor of an anionic surfactant, a neutralizing agent and aluminosilicate detergency builder into a horizontal thin-film evaporator/drier. The evaporator/drier comprises a mixing region, a drying region and a cooling region. Neutralization of the acid precursor is effected, together with granulation, drying and cooling, to form the detergent particles. At least some of the aluminosilicate builder is fed into the thin-film evaporator/drier between the drying region and the cooling region and/or into the cooling region. When all of he aluminosilicate builder is fed into the cooling region, the aluminosilicate is in an amount of more than 20% by weight of the particles exiting the cooling region.

Abstract: In order to improve the dispersion of nonionic surfactant into wash water from a granule in which the nonionic surfactant is carried on a water-insoluble granular material, the nonionic surfactant is intimately mixed with a structurant which is a non-soap ionic surfactant in finely divided particulate form. A preferred structurant is an anionic surfactant, for example, primary alcohol sulphate.

Abstract: An apparatus for attaching a tag and a thread length to a web of filter material with one end of the thread length secured to the tag and the other end being secured to the web adjacent one side edge of the web and the tag being attached to the web adjacent the opposite side edge. The apparatus has a gripper for drawing the tag, with the thread secured thereto, across the web from that one edge to an extended position beyond the opposite side edge before returning the tag to a final extended position over the web. The apparatus also has a mechanism for attaching the tag to the web in the final position, a displacement mechanism for the gripper means that has a first linear guide on which the gripper is slidable, and a second inner guide that is transverse to the first guide and fixedly located in the apparatus.
Abstract: An outer package is provided for strapping together at least two different articles. The package is a unitary cellulosic board forming primary and secondary hollow cavities of unequal volume, the primary cavity having opposite openings on first and second ends, the secondary hollow cavity having opposite left and right ends each coverable by a closure wall when folded into a closed position. A pair of article anchoring apertures are formed in the floor wall to secure any article held within the primary cavity. A blank is also described which when assembled through adhesive securement of head and tail terminal panels forms the outer package.
