Description

The present invention relates to liquid laundry compositions comprising silicone additives. More particularly the present invention relates to the use of silicone additives in liquid laundry compositions to increase the whiteness of laundered fabrics, as well as to improve their ease of ironing, hydrophilicity, and softness.
Clothing is a background feature of modern life. A principle issue with the use of clothing is that in wearing it attracts dirt / soil; both from a wearer and their surroundings.
Laundry detergent compositions that both clean and soften fabric during a laundering process are known and have been developed and sold by laundry detergent manufacturers for many years. Typically, these laundry detergent compositions comprise components that are capable of providing a fabric-softening benefit to the laundered fabric; these fabric-softening components include silicones.
Such washing is of course beneficial but one major issue is that whilst washing cleans and refreshes clothes; soiling in use is still inevitable. It would be greatly beneficial if there could be found a way to prevent / slow soiling of garments when they are worn. It would be supremely beneficial if one single composition could be identified which could address this prevention concern as well as providing excellent washing. Some liquid laundry detergent compositions comprising silicones are disclosed US 2006/003913 A1 , US 2005/233938 A1 , WO 2004/050813 A1 , WO 03/097778 A1 , WO 2009/127590 A1 , WO 2010/074810 A1 , WO 2008/152602 A1 , US 2012/004156 A1 , WO 2005/042829 A1 and US 7 049 276 B2 .
It is an on object of the present invention to address these problems.
According to a first aspect of the invention there is provided a composition comprising:

A) a liquid detergent product; and B) a silicone additive
comprising:
wherein the silicone additive comprises at least 80 mole percent of units

The liquid detergent product may comprise a laundry detergent product, a carpet detergent product, a hard surface (such as dishware) detergent product.
The present invention is directed to a method for laundering a textile fabric comprising washing said fabric in the presence of the above composition.
The present invention relates to the inclusion of a silicone additive in a liquid laundry product to impart increased whiteness, ease of ironing, and softness to the laundered article.
The benefits are delivered to the laundered items either during the wash cycle or the rinse cycle of the wash procedure. The silicone additives improve the properties of detergent compositions and rinse cycle additives. Such additives render the fabric, especially 100 percent cotton will and terry cloth, whiter and brighter than fabrics treated with liquid laundry compositions that do not contain these silicone additives. This increase in whiteness can be detected both visually and spectrophotometrically (reflectance) as measured by a Hunter Colorimeter. In addition, fabrics treated with these silicone additives in liquid laundry compositions require less effort to iron, and are softer to the touch than do those treated with liquid laundry compositions that do not contain these additives.
Further benefits include the facilitation of removal of greasy stains; especially on synthetic fabrics. This is postulated to be due to the higher oil repellency given by the formula; particularly on synthetic fibres. A yet further benefit includes colour fixing. In this regard it has been observed that when formula is applied directly (e.g. on a coloured fibrous material) and left for a period such as 24hrs, the colour of the garment is darkened (revived very visibly). It has also been found that a similar effect can be obtained after 10 repeated washing cycles using the formulation in the rinse cycle.
Similar benefits have also been noticed when the composition has been used when applied to carpets, hard surfaces (such as dishware).
The amount of silicone additive employed in the composition of this invention is from 0.01 wt. percent to 25 wt. percent, and more preferably, from 0.1 wt. percent to 10 wt. percent.
The viscosity of the polyorganosiloxanes (P) is preferably at least 1 and particularly at least 10 mPa-s and preferably at most 100 000 and particularly at most 10 000 mPa-s at 25 degrees centigrade
The polyorganosiloxanes (P) are obtainable via known chemical processes such as, for example, hydrolysis or equilibration.
Other silicones may also be present.

Other silicones include a Polyorganosiloxane-Silicone Resin Mixture

The polyorganosiloxane-silicone resin mixture comprises between about 50 percent to about 99.9 percent by weight of the mixture, of one or more polyorganosiloxane fluid compounds, at least about 0.01 percent by weight of the mixture, of one or more silicone resins, and a maximum of about 5 percent by weight of the mixture, of water. Certain embodiments of the polyorganosiloxane-silicone resin mixture may comprise between about 75 percent to about 98 percent of the polyorganosiloxane fluid compounds. Other embodiments may comprise between about 80 percent to about 90 percent, or alternatively between about 80 percent to about 87 percent of the polyorganosiloxane fluid compounds. Additionally, certain embodiments of the polyorganosiloxane-silicone resin mixture may comprise between about 0.1 percent and 50 percent, or between about 2 percent and about 30 percent of the silicone resins. Other embodiments of the mixture may comprise between about 5 percent and about 20 percent of the silicone resins.

Each of the one or more silicone resins of the polyorganosiloxane-silicone resin mixture contains at least 80 mol percent of unit

R¹⁰ ₂SiO_2/2 (VIII),

in which R¹⁰ means monovalent hydrocarbon residues with 1 carbon atom: Certain useful embodiments of the polyorganosiloxane-silicone resin mixture may comprise silicone resins comprising at least about 90 percent, at least about 95 percent, or at least about 98 percent of unit of general formula VIII.
The carrier of the surface treatment composition may be any known material, generally, but not necessarily, a liquid useful in delivering the polyorganosiloxane-silicone resin mixture to the surface which is desired to be treated. The carrier may be as simple as a single component delivery vehicle such as water or alcohol which would allow the mixture to be sprayed onto a surface. Alternatively, the carrier may be complex such as a cleaning composition such as a laundry detergent where the mixture would be applied in conjunction with the other beneficial uses of the complex carrier.
Preferably the composition comprises a wax component.
It has been observed that the wax component is able to improve the performance of the composition, especially with regard to stain repellency performance.

The wax component may contain one or more derivatization moieties. Preferred derivatisation moieties include ammonium, carboxylate, sulphate, sulphite, sulphonate, nitrate, halogen groups.

Stain release

Parity and Superiority versus detergent alone.
Improved performance on greasy stains: Chocolate syrup, French mustard, Lipstick and Mud and also some bleachable like Coffee and Tea thanks to the propyleneglycol. It is seen how also the formula without propyleneglycol performs well on water based stains while having some superiorities on greasy stains (make up and mustard) which it is believed are thanks to the contribution of the paraffin.
These results are particularly surprising. In separate tests the silicone and paraffin did not perform so well (see below).

A mix of cotton and polyester/cotton swatches washed in a European washing machine with a standard cotton 40°C cycle, dosing the following solutions during the rinse cycle under ideal conditions:

	Solutions	g/L active in the rinse cycle
P1	Not treated (washed only with detergent, nothing added to rinse cycle)	---
P2	Silicone (19.2% solution)	0.672 g/l
P3	Paraffin (30% solution)	0.750 g/l

Repellency results on water:

Arkophob FL 2150 30% sol. 1 min 10 sec 5 min 10 sec
Stain release results after having stained pre-conditioned swatches and washed again only with detergent:

Cotton

Conclusion: Silicone helps on waterbased stains but fixes oily stains, on cotton but also on cotton / PES (fixing is seen by the inferiorities). Paraffin looks to perform well across a wide range of stains (waterbased and oily stains) no matter the kind of swatch. Particularly looks to work well on greasy stains on cotton / PES swatch.
