Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a liquid detergent assembly for clothing, and more specifically, to a liquid detergent assembly for clothing, which has excellent shrinkage prevention properties (felt shrinkage prevention properties) and good rinsability. This invention relates to a lightweight liquid detergent composition for clothing. [Prior art and its problems] Delicate clothing such as wool products and silk products are washed by hand using a light detergent or by applying weak mechanical force to avoid damaging the fabric.

However, it is a common daily experience that among these types of clothing, wool products in particular have a tendency to shrink (felt shrinkage) even when careful care is taken, such as gently rubbing or washing them in lukewarm water. Conventionally, polyoxyethylene alkyl ether, polyoxyethylene alkyl ether sulfate, alkylbenzene sulfonate, etc. have been widely used as the main cleaning base for this type of light detergent. In recent years, alkyl saccharide surfactants have attracted attention as cleaning bases for light detergents because they are less irritating to the skin and have foaming properties. For example, JP-A-63-501
No. 641 discloses a detergent assembly for fine wire fabrics containing an alkyl glycoside and an antistatic quaternary ammonium surfactant, and JP-A-63-501642 discloses an alkyl glycoside and an antistatic amine oxide. It is described that a detergent assembly for fine fiber fabrics can provide better antistatic properties than when ordinary polyoxyethylene alkyl ether is used. Also, JP-A-64-6969
Publication No. 5 discloses a detergent composition using a combination of an alkyl glycoside and an amphoteric surfactant, and Japanese Patent Publication No. 1-168613 discloses a detergent composition using a combination of an alkyl glycoside and a phosphate ester surfactant. It is described that it has good foaming power and foam breakability. Furthermore, JP-A-59-25896 discloses 8LB 5 to 14 punion surfactants, alkyl glycosides, and di-long chain type quaternary surfactants.
It is stated that a detergent composition containing an ammonium salt has an excellent effect of removing particulate dirt, and can impart flexibility and antistatic properties.

However, even with the use of these detergents, shrinkage of wool products cannot be suppressed.

The present inventors have previously obtained particles having a cationic group or a tertiary amino group and having a particle size of o. It has been found that a light detergent containing a fine polymer latex of oos~0.2- is significantly effective in preventing felt shrinkage (Japanese Unexamined Patent Publication Nos. 8492-1982 and 89596-1983). However, it is difficult to stably incorporate the polymer latex into an alkyl glycoside detergent composition.

(Means for Solving the Problem) As a result of intensive research to solve the above-mentioned problem, the present inventors found that a cleaning agent & IlIfi product containing an alkyl glycoside and a certain type of silicone compound is excellent in preventing felt shrinkage. They found that the present invention was effective and exhibited good foaming properties, as well as improved rinsing properties, and thus completed the invention.

That is, the present invention provides: (a) alkyl glycoside 5 to 70% by weight
(9) Amino modified silicone or its derivative 0.05~
A liquid detergent for clothing containing 5% by weight of ikIltc is provided. The alkyl glycoside (a) used in the present invention is, for example, the following general formula (I) R+ (ORz),lGy (1) (wherein R+ is a linear or branched chain having 8 carbon atoms). ~18 alkyl group, alkenyl group or alkylphenyl group, h is an alkylene group having 2 to 4 carbon atoms, G is a residue derived from a reducing sugar having 5 or 6 carbon atoms, and X and y are average values. There it is,
X is a number from 0 to 5, and y is a number from 1 to 10. ) is preferred.

In general formula (1), R preferably has 9 to 14 carbon atoms from the viewpoint of solubility, foaming properties, and detergency. Further, R, preferably has 2 to 3 carbon atoms from the viewpoint of water solubility. In addition, the value of
It is preferable that it is in the range of ~4. It is desirable to select y in consideration of the physical properties derived from the hydrophobic group of R1, for example, R
, is a hydrophobic group having an average carbon number of 9 to 11, then y=t~
1.4 is a hydrophobic group having an average carbon number of 12 to 14, y=x. It is preferable to select s~4.0. Note that the average degree of sugar polymerization y can be determined by proton NMR. The binding mode of II1i is any one of 1-2, 1-3, 1-4 or 1-6 bonds, α- or β-viranoside bonds, or furanoside bonds, or a combination thereof. Furthermore, the structure of G is determined by the monosaccharide or polysaccharide that is the raw material, and examples of this monosaccharide include glucose, fructose, galactose, xylose, mannose,
Lyxose, arabinose, etc., and polysaccharides such as maltose, xylobiose, isomaltose, cellobiose, gentibiose, lactose, sucrose, nigerose, turanose, raffinose, gentianose,
Examples include melezitose, which can be used alone or in combination of two or more. Among these, from the viewpoint of availability and low cost, glucose, fructose, etc. are preferable as monosaccharide raw materials, and maltose, sucrose, etc. are preferable as polysaccharide raw materials.

The molecular weight of the silicone compound represented by the above general formula (II) is 2,000 to 150,000, and the straw equivalent is 1,000 to 1,000.
A range of 20,000 is preferred, and n is a number corresponding to these. (b) The ingredient is blended in the composition in an amount of 0.05 to 5% by weight, preferably 0.1 to 3% by weight.

It is generally known that silicone compounds, typified by dimethylborisiloxane, can be incorporated into detergents in small amounts as foam regulators. Also, JP-A-60-215
Publication No. 099 describes that flexibility can be imparted to clothing by incorporating a small amount of amino-modified silicone or its derivatives into detergent. However, these techniques do not disclose or suggest the structure and effects of the present invention using an alkyl glycoside system. The remainder of the composition of the present invention is water, but other nonionic surfactants, especially polyoxyethylene (average number of added moles of 5 to 2
0) The cleaning effect can be further enhanced without impairing the effects of the present invention by blending the alkyl (C9-14) ether in an amount of 50% by weight or less, preferably 10 to 50% by weight, based on the alkyl glycoside. It is undesirable to include cationic surfactants. This is because cationic surfactants have a stronger adsorption power to clothing than amino-modified silicones, and it is therefore presumed that the adsorption of amino-modified silicones is inhibited. Anionic and amphoteric surfactants can be incorporated in small amounts (5% by weight or less, preferably 1% by weight or less in the composition). The product of the present invention may contain other optional components that are commonly used in light detergents of this type. Such optional agents include recontamination inhibitors such as polyacrylic acid, polyvinylpyrrolidone, polyethylene glycol, and carboxymethyl cellulose; enzymes such as brotease, amylase, lipase, and cellulase; enzyme stabilizers such as calcium chloride;
Lower alcohols such as ethanol; lower alkylbenzenesulfonates such as benzenesulfonates and p-toluenesulfonates; glycols such as brobylene glycol; solubilizers such as benzoates and urea; t-butylated hydroxytoluene, Antioxidants such as distyrenated cresol;
Other examples include fluorescent dyes, blue tints, fragrances, and antibacterial agents.

Further, it is desirable that the composition of the present invention does not substantially contain a certain amount of ordinary detergent builders, but as long as the amount of builders such as diglycolate, phosphate, carbonate, etc. is 2 to 3% by weight or less. It can also be blended.
