The present invention relates to a powder detergent composition for clothes, and more specifically,
The present invention relates to a powder detergent composition for clothes, which has a significantly improved rinsability.

[Problems to be Solved by the Related Art and Invention] Since powder detergents for clothing in Japan are required to have foaming properties, anionic surfactants have been conventionally used as the main surfactant. The spread of fully automatic washing machines has been remarkable in recent years. When using a conventional high-foaming detergent in a fully automatic washing machine, foam may overflow during washing. In the case of a conventional washing machine, the turbidity of the rinsing liquid is visually confirmed to confirm the completion of rinsing.However, in the case of a fully automatic washing machine, such confirmation is not made. Anionic detergents having good properties have been demanded.

In order to solve this problem, current powder detergents contain antifoaming agents such as silicone and soap. Although silicone is effective even if added in a small amount, it is difficult to use because it has a problem of cost and it deteriorates the physical properties of the powder because it is oily, and soap is mainly used.

石けんは良好な抑泡効果を示すが、すすぎ性の面では
必らずしも充分と言えなかった。
Soap has a good foam-suppressing effect, but was not always sufficient in terms of rinsability.

As a result of earnest research to solve the above problems, the present inventors have found that rinsing properties are significantly improved by using a specific nonionic surfactant and cyclodextrin together with soap (higher fatty acid salt). Heading The present invention has been completed.

That is, the present invention relates to a powder detergent composition for clothing, which comprises a synthetic anionic surfactant as a main detergent base, wherein (a) higher fatty acid salt 1 to 6% by weight (b) polyoxyethylene (average addition of ethylene oxide) The present invention provides a powdery detergent composition for clothing, characterized in that it contains 0.5 to 6% by weight of an alkyl ether having a molar number of 8 to 20) and 0.1 to 5% by weight of (c) cyclodextrin.

Examples of the higher fatty acid salt used in the present invention include alkali metal salts of saturated or unsaturated fatty acids having an average carbon number of 10 to 20, preferably 16 to 18, and the like. If the content of the higher fatty acid salt in the detergent composition is less than 1% by weight, a sufficient foam-suppressing rinsing effect cannot be obtained, and if it exceeds 6% by weight, the smell of soap on laundry cannot be suppressed. When higher fatty acid salt is blended in an amount of about 3% by weight or more, soap odor tends to be imparted to laundry clothes. If so, the smell of soap can be sufficiently suppressed.

As the polyoxyethylene (ethylene oxide average addition mole number 8 to 20) alkyl ether of the component (b) used in the present invention, ethylene oxide is averaged to 8 to 20 moles in a primary or secondary alcohol having 8 to 18 carbon atoms. An added nonionic surfactant is included. If the average number of moles of ethylene oxide added is less than 8 moles, the effect of improving rinsability is poor, and if it exceeds 20 moles, disadvantages in detergent production occur. Polyoxyethylene (average number of moles of ethylene oxide added: 8 to 20) alkyl ether is added to the detergent composition of the present invention in an amount of 0.5 to 6% by weight. If the content is less than 0.5% by weight, the effect of improving the rinsability is poor, and if it exceeds 6% by weight, foaming becomes worse.

The cyclodextrin used in the present invention is β
Examples include cyclodextrin, β-cyclodextrin derivatives such as methylated β-cyclodextrin, α-cyclodextrin, and γ-cyclodextrin. Above all, β-cyclodextrin is preferred. Cyclodextrin is present in the detergent composition of the present invention.
The amount is 0.1 to 5% by weight, preferably 1.0 to 3.0% by weight. If the content of cyclodextrin is less than 0.1% by weight, the smell of soap cannot be sufficiently suppressed, and
It is economically unfavorable if it exceeds 5% by weight. Cyclodextrin can be used as a powder or granulated with a filler, a binder and the like. The object of the present invention can be sufficiently achieved even when cyclodextrin is used in the presence of a liquid perfume, and the effect of masking soapy odor can be expected by using such cyclodextrin.

In the detergent composition of the present invention, other detergent compositions are not particularly limited, but detergents in Japan generally include anionic interfaces such as sodium alkylbenzenesulfonate, sodium alkylsulfate, sodium olefinsulfonate and sodium alkylether sulfate. 10 to 50% by weight of activator,
30-80% by weight of inorganic builders such as sodium carbonate, sodium silicate, sodium sulfate and zeolite, and anti-staining agents such as polyethylene glycol and carboxymethyl cellulose, fluorescent dyes, enzymes and fragrances. Although a long-chain alkyl type quaternary ammonium salt is added to percarbonates, perborates, and soft detergents, the detergent composition of the present invention can also have such a formulation.
