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.
- 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.
- Non-limiting examples of such silicones include: non-functionalised silicones such as

- the powder of the present invention may in one embodiment be prepared by the following method:
- the other laundry product my for example be a powder laundry detergent, a laundry tablet, or a laundry unit dose capsule. Use of the powder
- the powder is used for softening benefits in other words as a softening booster for textiles.
- the powder may be incorporated into another laundry product or may be for use as a separate, stand-alone product which can be added during the wash process for a softening boost.
- the carrier material was added in to a Cutter C6 (ex. Sirman) mixer which was fitted with dough mix blades, and the mixer turned on.
- the carboxysilicone 1 and cationic polymer 2 where mixed separately and slowly dripped into the mixer while the mixer was running. Mixing was continued for a short period to ensure thorough mixing.
- the resulting powder was assessed visually. Dry powders which can flow more easily demonstrate higher loading capacity of the silicone, polymer mix. Damp and sticky powders demonstrate a lower loading capacity for the silicone, polymer mix.
- Unconfined compression test In this test, the freshly produced powders were compressed into a compact briquette and the force required to break the briquette was measured.
- the powder was loaded into a cylinder and the surface levelled. A 10 kg consolidation weight was placed slowly on top of the powder and allowed to remain in position for 2 minutes. The weight was then removed and the cylinder removed carefully from the powder to leave a free-standing briquette of powder. If the briquette remained standing, a 200g weight was placed on the top of the briquette. If after 10 seconds the briquette was still standing, a 250g weight was placed on top of the briquette. If after 10 seconds the briquette was still standing, a 10Og weight was added. 10Og weights continued to be added until the briquette collapsed.
- the cohesiveness of a powder is classified by the weight (w.t.) as follows: w.t. ⁇ 1 .0 kg Good flowing
- the visual assessment of the sodium carbonate and sodium tripolyphosphate carriers compared to the bentonite clay demonstrate that the two sodium carriers can carry more silicone and cationic polymer mix than the bentonite, while maintaining the properties of a flowing powder. Flowing powders are necessary for the processing and use of laundry products.
- the UTC results demonstrate that the sodium carriers are have a good flow / have improved flow compared to the bentonite clay, which was cohesive and required significantly more weight to make the briquette collapse. If the carrier is a poor carrier and does not hold all of the silicone and cationic polymer mix, the powder sticks together and can support weights. However if the silicone and cationic polymer mix is carried well, the carrier is a free flowing powder which falls apart when weights are place on top.
