Description

Liquid detergent for textiles and textiles

The present invention relates to a cleaning agent and a liquid cleaning agent for textile products.
The present application was filed on October 3, 2011, Japanese Patent Application No. 2011-219432, filed on December 28, 2011, Japanese Patent Application No. 2011-287187, filed on Japan, April 11, 2012 Priority is claimed based on Japanese Patent Application No. 2012-090361 filed in Japan and Japanese Patent Application No. 2012-110576 filed in Japan on May 14, 2012, the contents of which are incorporated herein by reference.

In general, non-surfactants (also referred to as nonionic surfactants) and anionic surfactants (also referred to as anionic surfactants) are used as main cleaning components in detergents for hard surfaces such as clothing and tableware and baths. And the like) are used.
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 cleaning agents that can be rinsed with a small amount of water and have good rinsing properties due to increasing awareness of environmental impact. In particular, washing machines such as drum-type washing machines, such as drum-type washing machines, are used, and cleaning agents are covered with a single rinse even under conditions of low water usage. There is a need to promote washing.
Conventionally, a foam control agent such as a higher fatty acid salt (soap) or a silicone-based antifoaming agent is blended in the detergent. Such a detergent contains a foam control agent, which suppresses foaming of the detergent (foam suppression), defoams the generated foam (antifoam), and improves rinsing properties. I am trying.

Alternatively, there has been proposed a cleaning agent that is improved in antifoaming properties and antifoaming properties by combining specific surfactants.
For example, a detergent containing an anionic surfactant, a defoaming agent, and at least one of a specific nonionic surfactant, an alkyl oligoglycoside and an alkenyl oligoglycoside has been proposed (for example, Patent Document 1).
In addition, for example, a cleaning 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 necessities such as detergents for textile products, development of products in consideration of the global environment is required. For example, by reducing the size of containers, energy is reduced and the amount of garbage is reduced in logistics.
In recent years, due to the widespread use of drum-type washing machines, etc., the bath ratio in washing (ratio of washing liquid to the object to be washed) has been decreasing. It is also desired that the amount used per hit is small and the amount of water required for rinsing is small.
In response to these demands, in the liquid detergent field, development of a composition (concentration) with an increased surfactant concentration is underway.

In concentrating the liquid detergent, a nonionic surfactant such as polyoxyalkylene alkyl ether is often used as a main washing component from the viewpoint of detergency and liquid stability. Nonionic surfactants such as polyoxyalkylene alkyl ethers have a strong degreasing power and are effective in cleaning sebum stains and the like adhering to clothing that is an object to be cleaned.
Further, as a liquid cleaning agent, a liquid cleaning agent having an action (softening action) capable of imparting flexibility to an object to be cleaned has been proposed in addition to high cleaning power.
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, it is intended to achieve good detergency, softening action, and good storage stability.

In general, there are mainly granular detergents and liquid detergents for textile products such as clothing, but the liquid detergent can be applied directly to the soiled part and washed (coating and washing). There are advantages in terms of usability.
A liquid detergent composition containing a specific nonionic surfactant, a hydrophobic organic solvent that is liquid at 20 ° C., and water is proposed as a liquid detergent with improved detergency in application cleaning (application detergency). (For example, Patent Document 4).

Furthermore, liquid detergents for textile products are required to increase the whiteness of appearance of textile products after washing (whitening effect) in addition to the improvement of detergency.

Conventionally, a liquid detergent composition containing a specific nonionic surfactant, an anionic surfactant, and a specific biphenyl-type fluorescent brightener has been proposed as a liquid detergent retroactive to the whitening effect ( For example, Patent Document 5).
In addition, for example, a liquid detergent composition containing specific amounts of a fluorescent brightening agent, a specific polyether-type nonionic surfactant, an anionic surfactant, and a specific chelating agent has been proposed ( For example, Patent Document 6).

Special table 2003-507570 gazette Japanese National Patent Publication No. 9-501195 JP 2010-265445 A JP 2011-168731 A International Publication No. 2010/029749 JP 2008-189754 A

However, the cleaning agents in the prior art cannot be said to be satisfactory in rinsing properties, and there is a demand for a cleaning agent that can be quickly moved with a smaller amount of water.
Then, one side of this invention aims at provision of the cleaning agent which was excellent in the defoaming property and the rinse property was improved.

Further, as a liquid detergent for textile products, further excellent softening action is required. However, in particular, when the object to be cleaned is cleaned at a low bath ratio, the conventional liquid cleaning agent may not be able to sufficiently exhibit the softening action.
Then, another side of this invention aims at providing the liquid detergent for textiles excellent in the softening effect | action even if the bath ratio is low.

In addition, the liquid detergent is usually stored in a container and distributed, but when it is filled into the container at the time of manufacture or when it is transferred from the refill container to the main container (hereinafter generally referred to as filling). There is a case that bubbles. When an anionic surfactant is blended in order to enhance the cleaning power of the liquid detergent, the foam film becomes stable and the foam becomes more difficult to disappear. In addition, when the viscosity of the liquid cleaning agent is lowered in order to increase the permeability to the object to be cleaned and improve the coating cleaning power, foaming tends to occur when the container is filled.
In liquid detergents formulated with higher fatty acids for the purpose of improving rinsing performance, calcium ions and higher fatty acids in tap water used for cleaning exhibit foam suppression and defoaming properties by forming calcium salts. . For this reason, it cannot suppress that a liquid detergent foams at the time of filling to a container by mix | blending a higher fatty acid.
In addition, the invention of Patent Document 4 does not take into consideration any suppression of foaming of the liquid cleaning agent when filling the container.
Furthermore, the liquid cleaning agent is required to further improve the cleaning power.
Accordingly, another object of the present invention is to provide a liquid detergent for textiles that has excellent detergency and is suppressed from foaming when filled into a container.

In recent years, as textile products (especially clothing), textile products made of chemical fibers have been increasing. For example, chemical fibers such as polyester are used for blouses and shirts. Chemical brightening products such as polyester are difficult to adsorb fluorescent whitening agents conventionally used for liquid detergents. For this reason, it was difficult to obtain a satisfactory whitening effect even when the chemical fiber product was washed using the liquid detergents of Patent Documents 5 and 6.
Accordingly, another object of the present invention is to provide a liquid cleaning agent for textiles that is excellent in whitening effect even for chemical textiles.
