Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION This invention relates to liquid bleach compositions.

0002

[Prior Art and Problems to be Solved by the Invention] Chlorine bleach has limitations on the types of fibers that can be used, cannot be used on colored or patterned fabrics, and has a unique odor. Oxygen bleaches, which have no disadvantages, have recently become very popular.

[0003] As the bleaching base for this oxygen bleach, sodium percarbonate and sodium perborate are particularly used from the viewpoint of bleaching performance and stability. However, since these bleaching bases are powders, they have drawbacks such as not being able to be applied directly to stains and are not easy to use, so liquid bleaching agents have recently been put on the market.

[0004] However, liquid bleaching agents have the disadvantage that their bleaching power is weaker than that of powder type bleaching agents.

[0005]

[Means for Solving the Problems] As a result of intensive research in order to obtain a liquid oxygen bleaching agent with higher bleaching power, the present inventors discovered that hydrogen peroxide and the following general formula (I)

Example 1 Various liquid bleach compositions shown in Table 1 were prepared and their bleaching effects were evaluated in the following manner. Evaluation method: To 300 ml of an aqueous bleach solution prepared by adding a bleaching agent having the composition shown in Table 1 to tap water at 20°C so that the effective oxygen concentration is 0.05%, a tea-stained cloth prepared as follows* was added. After soaking five sheets at 20° C. for 30 minutes, they were rinsed with tap water and dried, and the bleaching rate was calculated using the following formula.

[0076]

[Math 1]

The reflectance was measured using a colorimeter N-DR 101-DP manufactured by Nippon Denshoku Kogyo Co., Ltd.

*Tea-contaminated cloth: Boil 80 g of Nitto black tea (yellow package) in 3 liters of ion-exchanged water for about 15 minutes, then strain it through a desized dry cotton cloth, soak a cotton gold cloth #2003 in this liquid, Boil for about 15 minutes. Remove from heat, leave to stand for about 2 hours, then air dry, rinse with water until the washing liquid is no longer colored, dehydrate, press, and then dry for about 2 hours.
A test piece of cm x 10 cm was used for the experiment.

These results are shown in Table 1. In addition, in the table,
B stands for balance amount.
