Description

  The present invention relates to a detergent composition. More specifically, the present invention relates to washing clothes and cloths for hotels and restaurants, sheets for hotels and inns, pillow covers, towels and shirts for home cleaning in the linen supply field. The present invention relates to a detergent composition suitable for commercial detergents and heavy detergents that suppresses dye transfer between and within textile products and performs excellent washing performance.

  Conventionally, in the linen field, when washing textile products such as sheets, pillowcases, cook clothes, cloths, etc., it is possible to wash large quantities of items such as large vertical batch washers and continuous washing machines. A washing machine is used. In the field of home cleaning, a vertical batch washer is used to clean shirts and the like.

  This washing machine has a feature that it is easy to foam because it uses a cleaning method in a longitudinal rotation. As a detergent used, for example, a liquid detergent composition containing no ethanol (for example, see Patent Document 1), a liquid washing containing oleic acid Liquid detergent in a container containing the agent composition in a synthetic resin container (see, for example, Patent Document 2) A laundry detergent powder composition comprising a combination of two types of specific nonionic surfactants in a specific ratio (for example, , Patent Document 3), powder detergent composition for laundry containing a nonionic surfactant as a main cleaning base and a specific silica-based inorganic compound, low molecular weight polycarboxylic acid, etc. (see, for example, Patent Document 4) The low-foaming detergent described in 1) has been preferably used.

  However, the detergents and the like described in each of the above four patent documents cannot cope with the diversification of dirt accompanying the diversification of lifestyles in recent years, making it difficult to exert sufficient cleaning performance. It is becoming.

On the other hand, in the linen supply field, in order to cope with the diversification of user's taste, some textile products such as towels and cloths are increasing. Accordingly, a problem of so-called dye transfer has occurred, in which the pigment is eluted from the fiber product during washing and the color is transferred to another fiber product. The problem of this washing is that, in a continuous washing machine for washing various textile products, the washing water from which the pigment is eluted is also used for washing other textile products because of the structure that circulates the washing water. The problem of dyeing is becoming serious.
Furthermore, batch washers are mainly used in the home cleaning field for washing clothes brought in from ordinary households. However, since various textile products are washed in the same bath, the problem of dye transfer is serious as in the linen field.

A detergent composition comprising an N-vinylimidazole = N-vinylpyrrolidone copolymer as a cleaning composition for preventing migration, wherein the copolymer has a molecular weight of 5,000 to 50,000. (For example, refer patent document 5) and the dye movement suppression composition characterized by including a vinyl pyridine copolymer (for example, refer patent document 6) are known.
However, the detergent composition containing the dye transfer inhibiting composition described in these documents is an excellent one for preventing dye transfer at the time of washing, but still does not further improve the cleaning performance, At present, the appearance of a detergent composition capable of preventing transfer and further improving the cleaning performance is desired.
JP 61-166898 A (Claims, Examples, etc.) JP-A-61-60797 (Claims, Examples, etc.) Japanese Patent Laid-Open No. 11-21598 (Claims, Examples, etc.) JP-A-11-21599 (Claims, Examples, etc.) JP 9-502744 A (claims, examples, etc.) JP 2002-515921 A (Claims, Examples, etc.)

And

  As a result of intensive investigations on the above-mentioned problems of the prior art, the present inventors have obtained the above object by using a specific dye-transfer-preventing component and a compound obtained by adding alkyl glycidyl ether to a specific alcohol ethoxylate. The present inventors have found that a cleaning composition that exhibits excellent cleaning performance against diversifying soils and that suppresses dye transfer between textile products can be obtained, thereby completing the present invention. .
