Description

CLEANING AGENT AND LIQUID CLEANING AGENT FOR TEXTILE PRODUCT [0002]

The present invention relates to a detergent and a liquid detergent for textile products.

The present application is filed in Japan on Oct. 3, 2011, in Japanese Patent Application No. 2011-219432, on December 28, 2011, in Japanese Patent Application No. 2011-287187, on April 11, 2012 Japanese Patent Application No. 2012-090361, and Japanese Patent Application No. 2012-110576, filed on May 14, 2012, the contents of which are incorporated herein by reference.

Generally, nonionic surfactants (also called nonionic surfactants) or anionic surfactants (also referred to as anionic surfactants) are mainly used as cleaning agents for hard surfaces such as medical applications (for clothing), tableware and baths. ) Are used as surfactants.

As the nonionic surfactant, for example, polyoxyalkylene alkyl ether, polyoxyalkylene alkyl allyl ether, alkyl glycoside, fatty acid polyoxyalkylene alkyl ether and the like are used.

In recent years, there has been a demand for a detergent which can be rinsed with a small amount of water and is excellent in rinsing property because the consciousness of the environmental load becomes high. Particularly, a washing machine having a small amount of water consumption, such as a drum type washing machine, is used for cleaning medical treatment. As the cleaning agent, it is required to rinse the object to be rinsed by rinsing once even under a condition of a small water use amount .

Conventionally, a foam control agent such as a high-grade fatty acid salt (soap) or a silicone-based defoaming agent is mixed with a detergent. Such a detergent contains a foam control agent to suppress the generation of foam of the detergent (suppressing ability), and to bleach the resulting foam (defoaming property) to improve the rinsability .

Alternatively, a detergent has been proposed in which a specific surfactant is combined to improve the barrier properties and defoaming properties.

For example, detergents containing at least one of anionic surfactants, defoamers, and specific nonionic surfactants, alkyloligoglycosides and alkenyloligoglycosides have been proposed (see, for example, Patent Document 1 ).

Further, for example, a clear composition containing a specific alkyl polyglycoside and a specific fatty acid alkyl ester alkoxylate has been proposed (for example, Patent Document 2).

On the other hand, in the field of daily commodities such as detergents for textile products, development of products considering global environment is required. For example, by reducing the size of the container, it is possible to reduce energy consumption in logistics and reduce waste.

In recent years, the bath ratio (the ratio of the cleaning liquid to the object to be cleaned) in the laundry has been decreasing from the spread of the drum type washing machine and the like. The cleaning agent has a high cleaning power, It is desired that the amount of water used is small and the amount of water required for rinsing is small.

In response to this demand, in the field of liquid detergents, the development of a composition with an increased surfactant concentration (enrichment) is underway.

In the concentration of the liquid detergent, a nonionic surfactant such as polyoxyalkylene alkyl ether is often used as a main cleaning component from the viewpoints of washing power and liquid stability. Nonionic surfactants such as polyoxyalkylene alkyl ethers and the like are effective for cleaning dirt, sebum, etc. adhering to medical care which is strong in degreasing force.

As the liquid detergent, there has been proposed a liquid detergent having an action (softening action) capable of imparting flexibility to the object to be cleaned in addition to a high detergency.

For example, a liquid detergent composition containing a specific nonionic surfactant, an anionic surfactant, and a cationic surfactant in a specific ratio has been proposed (Patent Document 3). According to the invention of Patent Document 3, good washing power, softening action, and good storage stability are achieved.

In general, there are generally granular detergents and liquid detergents as detergents for textile products such as medical applications. Since the liquid detergent can be applied directly to a contaminated portion and cleaned (applied and cleaned) There is an advantage in terms of.

There has been proposed a liquid detergent composition containing a specific nonionic surfactant, a liquid hydrophobic organic solvent at 20 占 폚 and water as a liquid detergent for improving the cleaning power (applied cleaning power) in the applied cleaning (see, for example, 4).

In addition to the improvement of detergency, a liquid detergent for textile products is required to have a whitening effect on the appearance of the fiber product after washing (broadening effect).

Conventionally, a liquid detergent composition containing a specific nonionic surfactant, an anionic surfactant, and a specific biphenyl type fluorescent whitening agent has been proposed as a liquid detergent for obtaining a whitening effect (see, for example, Patent Document 5).

Further, for example, there has been proposed a liquid detergent composition containing a specific amount of a fluorescent whitening agent, a specific polyether type nonionic surfactant, an anionic surfactant, and a specific chelating agent, respectively (see, for example, Patent Document 6 ).

Patent Document 1: Japanese Patent Specification No. 2003-507570 Patent Document 2: JP-A-9-501195 Patent Document 3: JP-A-2010-265445 Patent Document 4: Japanese Patent Application Laid-Open No. 2011-168731 Patent Document 5: International Publication No. 2010/029749 Patent Document 6: JP-A-2008-189754

However, the cleaning agent in the conventional art can not be said to be satisfactory in the rinsing property, and a cleaning agent capable of rinsing with a smaller amount of water is demanded.

Therefore, one aspect of the present invention is to provide a cleaning agent excellent in defoaming property and improved in rinsability.

In addition, as a liquid detergent for textile products, an excellent softening action is also required. However, in particular, when the object to be cleaned is washed with a low bath, the conventional liquid detergent may not sufficiently exhibit the softening action.

Another object of the present invention is to provide a liquid detergent for textile products which is excellent in softening action even when the bath ratio is low.

The liquid detergent is usually stored and circulated in the container. When the container is filled in the container at the time of manufacture or when the container is changed from the container for refill (hereinafter referred to as " refill " ) May generate bubbles in some cases. If an anionic surfactant is added in order to increase the detergency of the liquid detergent, the foam film is stabilized and the foam is less likely to disappear. In addition, when the viscosity of the liquid detergent is lowered in order to enhance the permeability to the object to be cleaned to improve the application cleaning power, bubbles are liable to be generated when the container is filled.

In the liquid detergent formulated with a higher fatty acid for the purpose of improving the rinsability, the calcium ion in the tap water used for washing and the higher fatty acid form a calcium salt, thereby exhibiting suppression and defoaming. For this reason, in the case of blending a higher fatty acid, it is not possible to suppress foaming of the liquid detergent at the time of filling the container.

In addition, the invention of Patent Document 4 does not consider at all that the liquid detergent is prevented from foaming when the container is filled.

In addition, the liquid detergent is required to further improve the cleaning power.

Another object of the present invention is to provide a liquid detergent for textile products which is excellent in detergency and is suppressed from being foamed upon charging into a container.

In recent years, fiber products made of chemical fibers are increasingly used as textile products (in particular, medical products). For example, chemical fibers such as polyester are used for blouses, shirts, and the like. In a chemical fiber product such as a polyester product, a fluorescent whitening agent conventionally used in a liquid detergent is hardly adsorbed. For this reason, even if the chemical fiber products are washed using the liquid detergents of Patent Documents 5 and 6, it is difficult to obtain a satisfactory whitening effect.

Therefore, another object of the present invention is to provide a liquid detergent for textile products which is also excellent in the effect of enlarging the whiteness, even for chemical fiber products.
