Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dulling inhibitor composition for clothing, and more particularly, it is added at the time of rinsing in a washing process to suppress impurities in tap water from adhering to clothing. The present invention relates to a dullness inhibitor composition for clothing that can reduce dullness of clothing after drying.

[0002]

2. Description of the Related Art At present, detergents for clothes contain a re-staining agent for preventing particulate stains washed off from the clothes from adhering to the clothes again. There are many. Carboxymethylcellulose, polyvinylpyrrolidone and the like are known as such a re-staining agent. However, these recontamination inhibitors flow away together with the detergent when draining after washing.

On the other hand, tap water contains trace amounts of impurities such as heavy metals such as iron, which contributes to dullness of clothing. During washing, the re-staining agent incorporated in the detergent works effectively and can reduce the effects of these impurities, but as described above, the re-staining agent incorporated in the detergent is drained before the rinsing step. Since the wastewater is discarded together with the (washing water), the effect of removing impurities by the recontamination inhibitor mixed with the detergent cannot be expected for newly injected rinse water.

Therefore, it is necessary to take measures to reduce the influence of impurities in the rinsing step. Since the rinsing process is a process close to the final stage of the washing process, along with reducing dullness,
It is required that the clothes after the rinsing process be not adversely affected. For example, after the rinsing step, a performance that does not impair the feel of dehydrated and dried clothes is required, but a treatment agent that can achieve both reduction of dullness and feel of clothes has not been sufficiently studied.

[0005]

Means for Solving the Problems The present inventors have found that adding a specific water-soluble polymer at the time of rinsing in order to suppress this dullness has the effect of suppressing dullness without impairing the feel of clothing, The present invention has been completed.

It is intended to provide a dulling inhibitor composition for clothing characterized by the fact that it is obtained. (i) A water-soluble, non-cationic cellulose derivative having a weight average molecular weight of 1,000 to 100,000 [hereinafter sometimes referred to as polymer (i). (Ii) 1 having at least a vinyl group and / or an aromatic ring
A polymer having a weight average molecular weight of 10,000 to 500,000 or a salt thereof obtained by polymerizing one or more kinds of monomers and containing a sulfonic acid group [hereinafter, may be referred to as polymer (ii). (Iii) a carboxylic acid group-containing polymer having a repeating unit represented by the following general formula (I) or (II) or a salt thereof [hereinafter, also referred to as polymer (iii). ]
