Definitions
- the present invention concerns a powder composition for use in laundry.
- the powder may be used to provide softening benefits.
- Silicones are known in the art to provide softening benefits for example WO 2006/005068 (The Procter & Gamble Company) discloses liquid laundry detergent compositions containing functionalised silicone materials as fabric care agents. WO 2015/078692 discloses that fabric softening silicones have been used to provide softness to fabrics from a laundry detergent composition.
- EP 1561803 discloses a need to improve the fabric-softening performance of a laundry detergent composition without unduly negatively affecting its fabric-cleaning performance.
- an auxiliary composition for use in the laundering or treatment of fabrics, comprising a co-particulate admix, the co-particulate ad-mix comprising: i) clay; and ii) a hydrophobic component that is a silicone; and iii) a cationic polymeric fabric-softening boosting component that is a cationic guar gum; ...
- co-particulate admix is obtained by a process comprising the steps of contracting the hydrophobic component with the clay and the charged polymeric fabric-softening boosting component to form a mixture, and then agglomerating the mixture in a high shear mixer and/or a low shear mixer to form a co-particulate admix.
- a powder composition for laundry comprising silicone, cationic polymer and carrier wherein the silicone composition and cationic polymer are loaded onto the carrier and the carrier is selected from sodium carbonate, sodium tripolyphosphate and mixtures thereof and wherein the ratio of silicone to cationic polymer is between 5:4 and 8:1 and the combined weight of silicone and cationic polymer is 15 to 35 w.t.% of the powder composition.
- the present invention relates to a powder composition.
- the powder composition may be used in a powder form or formed into a whole or part of a tablet or solid structure.
- the powder composition may be utilised as a laundry product on its own to provide softening benefits for example as an ancillary product.
- the powder composition may be integrated into another laundry product to provide an additional softening benefit e.g. added to a powdered laundry detergent, added to a unit dose capsule or incorporated into a tablet.
- the powder forms part of a unit dose capsule or tablet, preferably the powder is contained in a unit does capsule. More preferably the powder is contained in a unit dose capsule which further comprises a detergent composition. Preferably the detergent composition is in a separate compartment to the powder.
- the silicones suitable for the present invention are fabric softening silicones.

Description
- The present invention concerns a powder composition for use in laundry. The powder may be used to provide softening benefits.
- Textile fabrics, including clothes, have traditionally been cleaned with laundry detergents. After cleaning, fabrics can often feel harsh. To prevent this, especially harshness experienced after multiple wash cycles, technologies have been developed to increase the softness of fabrics, including rinse-added conditioner compositions and softening systems added to the detergent composition.
- Silicones are known in the art to provide softening benefits for example
WO 2006/005068 (The Procter & Gamble Company) discloses liquid laundry detergent compositions containing functionalised silicone materials as fabric care agents.WO 2015/078692 discloses that fabric softening silicones have been used to provide softness to fabrics from a laundry detergent composition. -
EP 1561803 (The Procter & Gamble Company) discloses a need to improve the fabric-softening performance of a laundry detergent composition without unduly negatively affecting its fabric-cleaning performance. There is disclosed an auxiliary composition, for use in the laundering or treatment of fabrics, comprising a co-particulate admix, the co-particulate ad-mix comprising: i) clay; and ii) a hydrophobic component that is a silicone; and iii) a cationic polymeric fabric-softening boosting component that is a cationic guar gum; ... wherein the co-particulate admix is obtained by a process comprising the steps of contracting the hydrophobic component with the clay and the charged polymeric fabric-softening boosting component to form a mixture, and then agglomerating the mixture in a high shear mixer and/or a low shear mixer to form a co-particulate admix. - Further powder compositions for laundry comprising silicone and cationic polymer are disclosed in
