Description

Liquid detergent composition for clothing

Technical Field

The present invention relates to a liquid detergent composition for clothing.

Background

With the rising of the hygiene consciousness of the living persons, the concern about the odor of the clothing and the bacteria has also started to rise. It is known that skin-resident bacteria or various bacteria existing in the environment adhere to clothing and propagate. Since the clothing worn during the drying process after washing, which is not dried thoroughly, or sweating, contains a large amount of moisture, it is considered that the amount of metabolites is increased by the proliferation of bacteria, and odor is more likely to be generated.

As a method for suppressing the growth of bacteria adhering to clothing, for example, as disclosed in japanese patent application laid-open publication No. 2011-246585, a liquid detergent composition containing a nonionic surfactant as a main cleaning component and a quaternary ammonium salt having a hydrocarbon group having 6 to 22 carbon atoms as a main agent showing an odor eliminating effect against non-drying out is disclosed. Further, Japanese patent application laid-open No. 11-43405 discloses an antibacterial processing agent for low-irritation fibers, which contains a quaternary ammonium salt having an organic carboxylic acid as a counter ion.

On the other hand, in the case of cleaning a cloth to which dirt has adhered, there is a problem that the cleanability is not easily generated due to a problem of recontamination in which the dirt is detached from the cloth and then the dirt is reattached to the cloth again after the dirt is detached by the surfactant contained in the detergent composition for cloth. Among surfactants, anionic surfactants have been known to have fewer problems with recontamination than nonionic surfactants.

However, it is known that the bactericidal action by a cationic surfactant such as a quaternary ammonium salt is reduced in a composition containing an anionic surfactant as a main component. Jp 7-53995 a discloses a disinfecting detergent composition comprising a cationic disinfectant, a metal chelating agent in an amount of 0.5 times or more moles of the disinfectant, and a nonionic surfactant and/or an amphoteric surfactant, wherein the disinfecting effect is not reduced in a composition comprising an anionic surfactant. Japanese patent application laid-open No. 11-512768 discloses a structured heavy-duty liquid detergent composition containing an anionic surfactant such as alkyl polyethoxy sulfate and a quaternary ammonium surfactant, wherein the anionic surfactant and the quaternary ammonium surfactant form liquid crystal particles.

Disclosure of Invention

The following problems exist: even if a garment having dirt such as sebum dirt adhered thereto after wearing is washed, the dirt or bacteria adhered to the garment does not completely fall off.

Bacteria remaining in the clothing metabolize dirt such as sebum remaining in the clothing, and odor is generated by discharging odorous metabolites, and there is also a problem that odor is generated from the clothing worn for 1 day. Even when a quaternary ammonium salt is used, there is still room for improvement in order to suppress the growth of bacteria present in clothing.

Further, the present inventors have found that: when a cationic surfactant and a specific chelating agent are used in a liquid detergent composition for clothing containing an anionic surfactant, there is a problem that the storage stability is lowered, and particularly, separation or fogging of the composition occurs by storage at high temperatures.

In view of convenience in use, the proportion of a liquid detergent composition for clothing, which is in a liquid form, is increasing in the market for detergents. Therefore, in the liquid composition, it is desired to solve the above-mentioned problems.

The invention provides a liquid detergent composition for clothing, which can endow clothing with antibacterial property and has excellent storage stability.

The present invention relates to a liquid detergent composition for clothing, which contains 10-16% by mass of component (A), 1-3% by mass of component (B), 2-8% by mass of component (C), and component (D) and water,

the mass ratio of [ (content of component D ]/[ (content of component A) + (content of component B) ] is 0.1 to 0.4.

(A) The components: an anionic surfactant represented by the following general formula (1),

RO-(C₂H₄O)_mSO₃ ^-·M⁺(1)

[ wherein R is a hydrocarbon group having 10 to 16 carbon atoms, M is an average molar number of addition and is a number of 1 to 4, and M⁺Is a cation.]

(B) The components: a quaternary ammonium compound represented by the following general formula (2),

[ in the formula, R¹Is an aliphatic hydrocarbon group having 12 to 16 carbon atoms, R²、R³And R⁴Each independently is a group selected from methyl, ethyl and hydroxyethyl, X^-Is an anion.]

(C) The components: a polycarboxylic acid having 4 to 6 carbon atoms and 2 to 4 carbon atoms or a salt thereof,

(D) the components: a nonionic surfactant represented by the following general formula (3),

R⁵O-(C₂H₄O)_nH (3)

[ in the formula, R⁵Is a hydrocarbon group having 12 to 16 carbon atoms, and n represents an average molar number of addition and is a number of 10 to 40.]

The present invention provides a liquid detergent composition for clothing which imparts antibacterial properties to clothing and has excellent storage stability.

According to the present invention, there is provided a liquid detergent composition for clothing, which can effectively suppress not only the undried odor generated during drying but also the odor generated during wearing of dried clothing by imparting both functions of cleaning and antibacterial properties to clothing and washing the clothing having dirt adhered thereto.

Detailed Description

The liquid detergent composition for clothing of the present invention can have both cleaning performance and antibacterial performance because the anionic surfactant of component (a) and the quaternary ammonium compound of component (B) can coexist. In addition, in order to stably incorporate a quaternary ammonium compound such as the component (B) at a concentration that exhibits a sufficient antibacterial effect, a technique for improving storage stability is required. In the present invention, it was found that: by blending a nonionic surfactant having a large average addition mole number of ethyleneoxy groups in the component (D), the storage stability can be improved.

The liquid detergent composition for clothing of the present invention is a composition comprising an anionic surfactant as component (a), a cationic surfactant as component (B), a polycarboxylic acid as component (C), a nonionic surfactant having a specific average molar number of addition of ethylene oxide as component (D), and water. In general, when the components (a) and (B) coexist in water, a composite is formed, and both the cleaning property and the antibacterial property are lost. However, in the co-presence of the component (B) and the component (C) as in the present invention, the component (B) is more likely to form a complex with the component (C) than the component (a), and therefore, it is considered that the formation of a complex of the component (a) and the component (B) is suppressed, and the cleansing action by the component (a) and the action of imparting the antibacterial effect to clothes by the component (B) can be maintained. As shown in examples described later, the amount of the component (C) is large in view of improvement of antibacterial performance.

In addition, the present inventors found that: by blending the component (D), the storage stability, particularly at high temperatures, is improved. It is presumed whether the solubilization is carried out by forming a complex of the component (A) and the component (B) by incorporating the complex into a mixed micelle of the component (A) and the component (D).
