example

[0210] The following examples further describe and demonstrate embodiments within the scope of the present invention. These examples are given for illustrative purposes only and are not to be construed as limitations of the invention, since many variations may be made without departing from the spirit and scope of the invention.

example 1

[0213] Six percent (6%) by weight of treated precipitated silica available from Evonik under the tradename Sipernat D10 was dispersed in 86.3% poly In a diorganosiloxane fluid, the polydiorganosiloxane has a degree of polymerization of 65 and contains 80 mole % methylethylsiloxane groups, 19 mole % methyl 2-phenylpropyl (derived from α- methylstyrene) siloxane groups and 1 mol% divinyl crosslinking groups. 6.7% by weight of a 60% by weight solution of an organosiloxane resin having a M / Q ratio of trimethylsiloxane units to SiO2 units in octyl stearate (70% solids) was added is 0.65 / 1. The mixture was homogenized by a high shear mixer to form foam control agent FC1.

[0214] Fourteen (14) parts of the above foam control agent FC1 were mechanically mixed with 9 parts of glyceryl tribehenate supplied by Oleon. FC1 and molten glyceryl tribehenate were mixed at 70°C. Glyceryl monobehenate is miscible with the polydiorganosiloxane fluid, and the mixture has a melting point of 65...

example 2

[0217] Another similar suds control agent, FC2, was prepared essentially the same as FC1, except that the polydiorganosiloxane fluid was different from that in FC1. In FC2, instead of using an 86.3% polyorganosiloxane fluid, which has a degree of polymerization of 65 and contains 80 mole % methyldodecylsiloxane, 20 mole % methyl 2-phenylpropyl (derived from [ α]-methylstyrene) siloxane groups.

[0218] Thirteen and a half (13.5) parts of the above suds control agent FC2 were mechanically mixed with 9 parts of glyceryl tristearate supplied by Oleon. FC2 and molten glyceryl tristearate were mixed at 70°C. Glyceryl tristearate is miscible with polydiorganosiloxane fluid and the mixture has a melting point of 62°C. The mixture of glyceryl tristearate and FC2, and 4 parts of a 1% aqueous solution of Polyquaternium-10JR30M cationic polymer were slowly poured into a mixer into which 73 parts of sodium sulfate powder had been stirred. The mixture was continuously stirred until a gr...

Abstract

A laundry detergent comprises a granulated foam control composition and an anionic surfactant, wherein the granulated foam control composition comprises a foam control agent, an organic additive composition, a water soluble particulate carrier and a charged cationic polymer. The foam control agent comprises a polydiorganosiloxane fluid, a hydrophobic filler and optionally an organosilicone resin. A method of cleaning a fabric, a method of conserving water when washing fabric and a method of saving time when washing fabric are also disclosed.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of PCT Chinese patent application PCT / CN2010 / 002009 filed on December 10, 2010. technical field [0003] The present invention relates to laundry detergents. In particular, the present invention relates to laundry detergents comprising a granular suds controlling composition comprising silicone. Background technique [0004] Laundry detergents have been known for many years and contain surfactants, usually anionic surfactants, for cleaning fabrics such as clothes. Laundry detergents typically generate suds during their use including during hand washing use. During hand washing of clothes and fabrics, where the user is fully involved in the washing process, a good amount of suds is initially expected as this indicates to the user that there is enough surfactant present, working, and cleaning the fabric. However, during the rinse cycle, typical hand laundry detergent users t...
