Definitions

• the present invention relates to a liquid detergent composition.
• the present invention relates to a light-duty liquid detergent composition having an excellent effect of preventing the shrinkage of clothes (effect of preventing felting shrinkage) and also a good rinsability.
• Delicate clothes made of wool or silk are usually washed by hands or a weak mechanical power with a light-duty detergent so as to prevent the damage to them.
• Conventional light-duty detergents of this type contain a polyoxyethylene alkyl ether, polyoxyethylene alkyl ether sulfate, alkylbenzenesulfonate, etc., as the main detergent base.
• alkyl saccharide surfactants attract attention, since they little irritate the skin and have lathering properties and, therefore, are usable as the light-duty detergent base.
• Japanese Patent Laid-Open No. 501641/1988 discloses a detergent composition for delicate cloths which contains an alkyl glycoside and an antistatic quaternary ammonium surfactant
• Japanese Patent Laid-Open No. 501642/1988 describes that a detergent composition for delicate cloths which contains an alkyl glycoside and an antistatic amine oxide is capable of imparting antistatic properties superior to those imparted when an ordinary polyoxyethylene alkyl ether is used.
• Japanese Patent Laid-Open No. 69695/1989 discloses a detergent composition containing both of an alkyl glycoside and an amphoteric surfactant and Japanese Patent Publication No.
• JP-A No. 25896/1984 describes that a detergent composition containing a nonionic surfactant having an HLB of 5 to 14, an alkyl glycoside and a di-(long-chain alkyl) quaternary ammonium salt is quite effective in removing stains in granular form and is capable of imparting softness and antistatic properties to the clothes.
• liquid detergent composition for clothes comprising:
• R1 in the general formula (I) preferably has 9 to 14 carbon atoms.
• R2 has preferably 2 or 3 carbon atoms.
• the water solubility and crystallizability vary depending on the value of x . The higher the value of x, the higher the water solubility and the lower the crystallizability.
• x is preferably in the range of 0 to 2, particularly 0.
• y is preferably in the range of 1 to 4. y is desirably selected in consideration of the properties ascribable to the hydrophobic group R1.
• R1 is a hydrophobic group having 9 to 11 carbon atoms on the average
• y is preferably 1 to 1.4
• y is preferably 1.5 to 4.0.
• the average degree of polymerization, y , of the reducing sugar can be determined by proton NMR.
• the bonds in the sugar chain may be 1-2, 1-3, 1-4 or 1-6 bond, ⁇ - or ⁇ -pyranoside bond or furanoside bond, or a combination of them.
• the structure of G varies depending on the starting monosaccharide or polysaccharide.
• the monosaccharides include glucose, fructose, galactose, xylose, mannose, lyxose and arabinose.
• the polysaccharides include maltose, xylobiose, isomaltose, cellobiose, gentiobiose, lactose, sucrose, nigerose, turanose, raffinose, gentianose and melezitose. They can be used either alone or in combination of two or more of them. Glucose and fructose are preferred among the monosaccharides and maltose and sucrose are preferred among the polysaccharides, because they are easily available and inexpensive.
• the amount of the component (a) is 5 to 70% by weight, preferably 10 to 40% by weight, based on the composition.
• Examples of the preferred amino-modified silicone or derivative thereof used as the component (b) in the present invention are compounds of the following general formula (II): wherein: R represents an alkyl group having 1 to 4 carbon atoms, a hydroxyl group or an alkoxy group, R1 groups may be the same or different from one another and each represent an alkyl group having 1 to 4 carbon atoms, A represents R1 or -(CH2) a -(OC2H4) b -(OC3H6) c -OR2 in which: a represents 2 or 3, b and c each represent 0 or 1 to 30 with the proviso that both of them do not represent 0 at the same time, and R2 represents an alkyl group having 1 to 24 carbon atoms; B represents in which: d and e each represent 2 to 6, R3 and R4 each represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, X represents a hydrogen atom, an alkyl group having 1 to 24 carbon atoms or
• silicone compounds represented by the above general formula (II) those wherein B represents and X represents an alkyl group having 1 to 24 carbon atoms or are preferred.
• silicone compounds of the above general formula (II) those having a molecular weight of 2,000 to 150,000 and amine equivalent in the range of 1,000 to 20,000 are preferred and m and n are numbers variable depending on the molecular weight.
• the amount of the component (b) is 0.05 to 5% by weight, preferably 0.1 to 3% by weight, based on the composition.
• silicone compounds such as dimethylpolysiloxane can be incorporated into detergents in a very small amount as a lathering regulator.
• Japanese Patent Laid-Open No. 215099/1985 describes that when a small amount of an amino-modified silicone or its derivative is incorporated into a detergent in a small amount, the clothes washed therewith can be softened.
• these techniques neither teach nor suggest the construction or effect of the present invention wherein an alkyl glycoside is used.
• the balance of the composition of the present invention comprises water.
• another nonionic surfactant particularly, a polyoxyethylene (having an average molar number of addition of 5 to 20) alkyl (C9 to C14) ether
• the deterging effect thereof is further improved without impairing the effect of the present invention.
• Incorporation of a cationic surfactant is undesirable, since its adsorbability on the clothes is higher than that of the modified silicone and, therefore, the adsorption of the amino-modified silicone would be inhibited.
• An anionic or amphoteric surfactant can be incorporated thereinto in only a small amount (not more than 5% by weight, preferably not more than 1% by weight, based on the composition).
• composition of the present invention may contain other components ordinarily incorporated into such a light-duty detergent.

• solubilizer Up to 15 wt.%, preferably up to 10 wt.%, of the solubilizer may be used here to prevent the phase separation. It is not needed when a small amount of a surfactant is only used.
• composition of the present invention is desirably substantially free from ordinary builders for detergents, not more than 2 or 3% by weight of a builder component such as a diglycolic acid salt, phosphoric acid salt or carbonic acid salt can be incorporated thereinto.

• a wool cloth, not yet treated for prevention of shrinking, having a size of 10 x 10 cm, three sides of which had been hemstitched with a lockstitch machine was immersed in city water at ambient temperature for 30 min, then dewatered in a dewatering tank of a washing machine for 30 sec, dried on a net and kept at 20°C and 65% RH for at least 4 h.
• the cloth was marked at four points with an oil-base felt pen and numbers were given to the marks. The distances between the marks (a 0 1 and a 0 2 in the direction of the length and b 0 1 and b 0 2 in the direction of the width) were measured. The distances will be called the "original length".
• R.M. represents the distances measured before washing (original length) and W.M. represents the distance measured after washing.
• W.S. represents the felting shrinkage in the direction of the width and L.S. represents the felt shrinkage in the direction of the length.
• rinse index The height (cm) of the lather 5 min after the washing and that 1 min after the press rinsing were macroscopically observed and evaluated according to the following criteria: rinse index:
• Perclene is the tradename of perchloroethylene.
• the detergency was determined by measuring the reflectivity of the original cloth before staining and those of the stained cloth before and after washing with an autographic colorimeter (mfd. by Shimadzu Corp. to calculate the deterging rate (%) according to the following equation (the average of the five samples is given in the Table):
