Description

  The present invention relates to a cleaning composition for clothing.

Washing clothes can be done by (1) “fading” in which some of the coloring components such as dyes are decomposed and bleached by chlorine compounds blended in tap water for sterilization, and (2) the coloring components in the washing liquid. “Color fading” that elutes and drops from clothing, and (3) discolored coloring components may cause discoloration such as “transfer” that adheres to other clothing, particularly white clothing.
Under such background, conventionally, a technique for capturing a chlorine compound in tap water using amines has been reported for preventing fading (Patent Document 1, etc.). With respect to prevention of dye transfer, a technique for blending a dye transfer inhibitor capable of forming a complex with a color component eluted in a washing liquid has been reported. As the dye transfer inhibitor, for example, polyvinyl pyrrolidone (PVP), poly (vinyl pyridine betaine) (Patent Document 2, etc.), polyamine N-oxide polymer (Patent Document 3, etc.) and the like are disclosed.

However, the above-mentioned prior color fading prevention technology does not exert any effect on the color fading in which the colored component is lost or the transfer by the dropped colored component. Similarly, the above-mentioned prior dye transfer prevention technology only stops the color component that has fallen off from adhering to other clothing, and is suitable for color fading that causes the color component to fall off and color fading in which the color component is bleached. It has no effect. Thus, conventionally, there has been no report on a technique for simultaneously suppressing fading, color fading, and migration.
Conventionally, there is no idea of preventing discoloration (coloring component removal), and there is no report on a technique for preventing discoloration.

  This invention is made | formed in view of this situation, and it aims at providing the cleaning composition for clothing which suppresses the fading, discoloration, and dye transfer which are discoloration of clothing simultaneously.

  As a result of intensive investigations on color fading prevention, the present inventors have formulated an anionic surfactant and a cationic polymer capable of forming a cationic complex with a specific composition, and a long chain amine. By blending together, it is possible to suppress fading and discoloration of clothing, and furthermore, as a result of suppressing the loss of the coloring component itself, it has been found that the migration of the coloring component to other clothing can be suppressed at the same time. Completed the invention.

That is, the laundry detergent composition of the present invention comprises a nonionic surfactant (A), an anionic surfactant (B), a long-chain amine (C), and a cationic polymer (D). And the molar ratio ((M) / (B)) between the cationic monomer unit (M) and the anionic surfactant (B) in the cationic polymer (D) is more than 1/1. It is characterized by being.
In the present specification, the “long chain amine” is defined as an amine having at least one hydrocarbon group having 8 or more carbon atoms.
The composition of the present invention is suitably used for preventing discoloration, which is a loss of colored components of clothing.

  ADVANTAGE OF THE INVENTION According to this invention, the detergent composition for clothing which suppresses the fading, discoloration, and dye transfer which are discoloration of clothing simultaneously can be provided.

Hereinafter, the present invention will be described in detail.
The laundry detergent composition of the present invention contains a nonionic surfactant (A), an anionic surfactant (B), a long-chain amine (C), and a cationic polymer (D). Do it. The composition of the present invention may be in a liquid form or in a solid form such as a granular form or a tablet form.
In this invention, (B) component and (D) component are mix | blended for color fading and dye transfer prevention, and (C) component is mix | blended for fading prevention.

The present inventors blended an anionic surfactant (B) and a cationic polymer (D) capable of forming a cationic complex with a specific composition so that these complexes can be used as clothing. It has been found that it can be efficiently adsorbed on the surface of the fiber to cover and protect the coloring components of the clothing such as dyes and to prevent the coloring components from falling off, that is, the color fading. The inventors have also found that the composite adsorbs well to clothing and suppresses discoloration both during washing and when rinsing. Furthermore, it has been found that, as a result of preventing the color components from dropping off, the migration of the color components to other garments can be suppressed at the same time.
In addition, regarding the prevention of migration, conventionally, there is only an idea of preventing migration by blending a component that acts on the fallen colored component, and migration is prevented by preventing the fallout of the colored component itself. The idea of the present invention is novel.
In addition, in the present invention, the long-chain amine (C) having an anti-fading effect is blended to prevent fading, but the present inventors use the (B) component and the (D) component together. Thus, it has been found that a more prominent anti-fading effect appears. This is because the long-chain amine (C) is taken into the hydrophobic field in the complex and is efficiently adsorbed on the clothing, thereby trapping chlorine compounds in the tap water on the fiber surface of the clothing and fading. It is inferred that it is controlled efficiently.

The average added mole number p of EO is less than 3, or the average added mole number of PO When q exceeds 6, the storage stability of the composition at a high temperature tends to decrease, which is not preferable.
The added mole number distribution of EO or PO varies depending on the reaction method during the production of the nonionic surfactant (A), and is not particularly limited. For example, the EO or PO addition mole number distribution is relatively wide when ethylene oxide or propylene oxide is added to a hydrophobic group raw material using a general alkali catalyst such as sodium hydroxide or potassium hydroxide.
