Method for softening knitted cotton, wherein knitted cotton is treated with an ancillary laundry composition comprising: a. Soil release polymer b. Silicone c. less than 4 w.t. % surfactant; and d. Water wherein the method comprises delivering the ancillary laundry composition into the wash or rise stage and comprises the steps of: a. Pouring a laundry product into a washing receptacle, a washing machine drawer, or a dosing shuttle b. Pouring the ancillary laundry composition on top of the laundry product. Use of the method for softening knitted cotton.

Laundry additive composition comprising a soil release polymer/silicone mixture

An ancillary laundry composition comprising: (a) 2.5-30 w.t. % fabric softening silicone; (b) Less than 2 w.t. % surfactant; (c) 0.25-10 w.t. % cationic polymer (d) Water.

Laundry composition additive

An ancillary laundry composition comprising: a) 2-20 w.t. % functionalised fabric softening silicone; b) Less than 5 w.t. % surfactant; c) 0.35-10 w.t. % cationic cellulose polymer d) Water 10 wherein the functionalised fabric softening polymer and cationic cellulose polymer are present in a ratio of 5:2 to 1:6 by weight.

Ancillary laundry composition

The invention relates to a fabric treatment composition comprising: a) from 50 to 95 wt. % of polyethylene glycol; b) from 0.1 to 15 wt. % of perfume; c) from 0.1 to 2.5 wt. % of cationic polymer; and, d) from 0.1 to 5 wt. % of silicone.

Fabric treatment composition

The invention relates to a fabric treatment composition comprising: a) from 60 to 99 wt. % of polyethylene glycol; b) from 0.1 to 5 wt. % of cationic polymer; and, c) from 0.1 to 10 wt. % of silicone.

Fabric treatment composition comprising peg and an anionic and/or cationic silicone

The present invention provides a coated detergent particle having perpendicular dimensions x, y and z, wherein x is from 0.5 to 2 mm, y is from 2 to 8 mm, and z is from 2 to 8 mm, wherein the particle comprises: (i) from 20 to 39 wt % of a surfactant selected from: anionic and non-ionic surfactants; (ii) from 10 to 40 wt % of an inorganic salt coating selected from: sodium carbonate and/or sodium sulphate of which at least 5 wt % of the inorganic salt is sodium carbonate; and, (iii) from 10 to 40 wt % of calcite having a median particle size average diameter (D50) in the range from 10 to 70 microns, and wherein the inorganic salts are present on the detergent particle as a coating and the surfactant is present in a core with the calcite dispersed through the core.

Laundry detergent particles

A process for manufacturing detergent particles comprising the steps of: a) forming a liquid surfactant blend comprising a major amount of surfactant and a minor amount of water, the surfactant part consisting of at least 51 wt % linear alkylbenzene sulfonate and at least one co-surfactant, the surfactant blend consisting of at most 20 wt % nonionic surfactant; b) drying the liquid surfactant blend of step (a) in an evaporator or drier to a moisture content of at most 2 wt % and cooling the output from the evaporator or dryer; c) feeding the cooled material, which output comprises at least 93 wt % surfactant blend with a major part of LAS, to an extruder, optionally along with less than 10 wt % of other materials such as perfume, fluorescer, and extruding the surfactant blend to form an extrudate while periodically cutting the extrudate to form hard detergent particles with a diameter across the extruder of greater than 2 mm and a thickness along the axis of the extruder of greater than 0.2 mm, provided that the diameter is greater than the thickness; d) optionally, coating the extruded hard detergent particles with up to 30 wt % coating material selected from powdered inorganic material and mixtures of such material and nonionic material with a melting point in the range 40 to 90&#xb0; C.
