Detailed Description
Polysaccharides grafted with anionic functional silicones
Polysaccharides are long-chain polymeric substances consisting of the same or different sugar rings. The polysaccharide may be linear or branched.
Examples of linear polysaccharides are polydextrose and polymannan polysaccharides. Examples of branched polysaccharides are glucomannan, galactomannan, and xyloglucan polysaccharides.
Preferably, the polysaccharide is selected from: polydextrose, polymannan, glucomannan, galactomannan, and xyloglucan polysaccharides. More preferably the polysaccharide is a galactomannan and/or xyloglucan.
Anionic silicones
The polysaccharide has an anionic functional silicone grafted thereto. By anionic functional silicone is meant a silicone that once grafted onto the polysaccharide has at least one residual anionic group. Preferably, the silicone, once grafted onto the polysaccharide, has at least 2 anionic groups, more preferably at least 3 anionic groups. Preferably, the silicone, once grafted onto the polysaccharide, has from 1 to 10, more preferably from 2 to 10, most preferably from 3 to 10 anionic groups.
The anionic groups can be detected using methods available in the art, such as NMR or IR spectroscopy.
Grafting of anionic silicones to polysaccharides usually requires reaction by anionic groups. Thus, when using monofunctional anionic silicones, the anionic groups are used up to enable grafting onto the polysaccharide. This means that the silicone will not have any anionic groups remaining once grafted onto the polysaccharide.
The invention requires the retention of at least one anionic moiety on the grafted silicone. This provides a laundry detergent composition with improved stability and less haziness or cloudiness.
Preferably, the anionic silicone has an anionic group content of at least 0.1 mol%, preferably 0.5 mol%, more preferably 1 mol%, most preferably 2 mol% once grafted.
Examples of anionic silicones are silicones comprising carboxylate, sulfate, sulfonate, phosphate and/or phosphonate functional groups.
Preferred anionic silicones are carboxy-functional silicones.
Preferably, the at least one residual charged species remaining on the anionic silicone is provided by a carboxysilicone.
Preferably, the polysaccharide is a galactomannan and/or xyloglucan having a silicone grafted thereto, wherein the silicone has at least 1 carboxyl group, preferably 2 carboxyl groups, after grafting.
For the purposes of the invention disclosed herein, the anionic silicone may be in the acid or anionic form. For example, for carboxy-functionalized silicones, it may be present as a carboxylic acid or carboxylate anion.

Examples
Example 1: comparison of compatibility of anionically functionalized and non-anionically functionalized silicone grafted polysaccharides
Synthesis 1: grafting of multifunctional carboxy silicones onto xyloglucans to provide anionically functionalized silicone grafts
Polysaccharides (examples of the invention)
To 5g (0.28mmol) of carboxy functional Silicone fluid (supplied by Wacker Silicone) was added 4ml of oxalyl chloride and mixed well. The reaction was monitored by the release of volatile gases and continued until effervescence ceased. Sodium bicarbonate was added to quench the unreacted oxalyl chloride. The acid chloride functional silicone was dissolved in 25ml of dichloromethane and then stirred rapidly, 1g of xyloglucan powder and 5ml of triethylamine were added. The reaction was heated to 40 ℃ and allowed to react until the dichloromethane distilled off, leaving the product dispersed in triethylamine.
The resulting polysaccharides of the grafted silicone have residual anionic groups after the grafting process is complete.
Synthesis A: grafting monofunctional carboxy silicones to xyloglucans to provide non-anionically functionalized silicone-grafted polypeptides
Candy (comparative example)
The procedure detailed in WO 2003/020770 was repeated using 0.28mmol of X-22-3710 (monofunctional carboxy silicone supplied by Shin Etsu) and xyloglucan (1g as Synthesis #1) instead of cellulose monoacetate.
By using monofunctional anionic silicones, the grafting process depletes this anionic functionality to form silicone grafted polysaccharides with no anionic groups remaining after grafting.

Compatibility testing:
the product of synthesis 1 or synthesis a was added to the test formulation to prepare silicone grafted xyloglucan at 0.5% activity level. The resulting formulations were evaluated in two ways. The first evaluation was a visual evaluation to see if the formulation was clear or cloudy/hazy. The second evaluation was the absorbance at 500 nm. The samples were transferred into 1cm cuvettes and the results were compared to control test formulations by measuring the sharpness in a 500nm UV-Vis spectrometer. The higher the + ve value, the less clear the sample.
The results show that silicone grafted polysaccharides with anionic groups remaining exhibit clear stability advantages in providing less hazy/cloudy formulations compared to grafting with monofunctional silicones resulting in silicone grafted polysaccharides with no anionic groups remaining.
