Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bleaching composition for bleaching and moulding clothes, fibers, pulps and kitchens for household and industrial use, and particularly to a bleaching group in the composition. The present invention relates to a liquid bleaching composition which is excellent in stability of agents and aroma with little change with time.

2. Description of the Related Art Conventionally, chlorine bleaching agents which are generally used as liquid bleaching agents are inexpensive and have a strong bleaching power, but they cannot be used for colored patterned clothing because they discolor or discolor the object to be treated. However, in recent years, there has been a social problem that chlorine gas is generated due to the accidental mixing with an acidic cleaning agent, causing a fatal accident. On the other hand, the oxygen-based bleaching agent is excellent in that it can be used in a wide range of clothes and there is no problem of chlorine gas generation.
However, most of the oxygen-based bleaching agents on the market are powder types with sodium percarbonate or sodium perborate as the main ingredient, which is inconvenient to use and is used especially for partial stains such as stains. It has the drawback that it cannot

Although the use of hydrogen peroxide as a base for an oxygen-based bleaching agent is widely practiced among laundry companies, mainly in the laundry industry, etc., it is not necessary to use hydrogen peroxide as a base for bleaching such industrial clothes. The hydrogen oxide liquid has a high hydrogen peroxide concentration of 35% by weight or 60% by weight (hereinafter simply referred to as "%"). On the other hand, in Japan, those with a hydrogen peroxide concentration of 36% or more are classified as "Type 1 dangerous substances" by the "Fire Defense Law", and those with hydrogen peroxide concentration of more than 6% by "Poisonous and Deleterious Substances Control Law" Since it is designated as "material", it is necessary to dilute the hydrogen peroxide concentration to at least 6% or less for safe use in general households. However, although a high-concentration product of hydrogen peroxide is relatively stable, there is a problem that when diluted, the stability rapidly deteriorates and the decomposition becomes easy. Therefore, various proposals have been made to suppress decomposition with a low-concentration hydrogen peroxide solution. JP-A-63-110
As a stabilizer for hydrogen peroxide, Japanese Patent Publication No. 294 discloses that a chelating agent such as aminopolyphosphate or ethylenediaminetetraacetic acid, or BHT (dibutylhydroxytoluene).
And the use of antioxidants such as MTBHQ (mono-t-butylhydroquinone).

Certainly, from the viewpoint of the decomposition rate of hydrogen peroxide, it is possible to reach a level practically no problem by using these methods. However, in terms of the amount of gas generated, this level is insufficient. For example, 2% of a 6% hydrogen peroxide solution is placed in a container with an internal capacity of 550 ml.
Filling 500 ml at 5 ° C and storing at 50 ° C After one month, if the hydrogen peroxide concentration is reduced to 5.8%, the decomposition rate of hydrogen peroxide is only 3%, but the oxygen gas generated And the pressure inside the container is about 9 atm. Therefore, a normal polyethylene container cannot withstand this internal pressure and swells, or in some cases, bursts.

On the other hand, in order to solve these problems, Japanese Patent Laid-Open No.
In Japanese Patent Laid-Open No. 115399, when a fragrance having a specific physical property value is added to a hydrogen peroxide solution, the decomposition of hydrogen peroxide hardly affects the decomposition of hydrogen peroxide and the generation of oxygen gas. It is possible to control. However, such a fragrance has a drawback that a decrease or change in fragrance is observed upon storage at high temperature, which causes a problem in commercial value.

[0006]

EXAMPLES The present invention will be specifically described below with reference to Examples and Comparative Examples, but the present invention is not limited to the following Examples. In addition,% in each example is% by weight.
Evaluation of each example was performed by the following methods.

(1) Method for measuring gas generation After filling the upper end of the opening of a 500 ml Erlenmeyer flask with a grounding stopper (total internal volume of about 555 ml) shielded from aluminum foil with water, 55 ml of water was pipetted. Make a mark on the water surface after removing the. Drain the water and pour liquid bleach into this position. After placing in a constant temperature bath for 30 minutes, slide the glass tube with stopper (the length of the slide is 10 or more.
It has a uniform inner diameter with a length of 0 cm and a length of 15 cm or less, which is equal to or less than the slippage. ) Apply a thin layer of silicone grease to the pickpocket and insert it into the flask. At this time, be careful that the meniscus part is located above the pickpocket. After confirming that the grease has spread all around the stopper, fix it with a spring or rubber band. Cover the stopper with aluminum foil and leave it in a thermostat at a predetermined temperature (the water level of the thermostat is the opening of the flask) for 2 hours, and then record the position of the meniscus.
At the same time, adjust a similar set with ion-exchanged water. After standing for a predetermined period, the rise of the meniscus is measured, and the gas generation amount is calculated by the following formula 1.

[0032]

[Equation 1] Amount of gas generated (ml / 500 ml) = (χ−χ ₀ ) π (d / 2)
² χ = rise of meniscus of liquid bleach (cm) χ ₀ = rise of meniscus of ion-exchanged water (cm) d = inner diameter of glass tube (cm)

(2) Measurement of bulge of bottle 600 ml of a bleaching agent composition was filled in a polyethylene cylinder bottle (full volume: 725 ml, bottom thickness: 0.6 mm, bottom of this bottle is recessed inward). Then 2
After the cap was sealed at 5 ° C. and stored in a thermostat at a predetermined temperature, the swelling of the bottle was visually observed at that temperature. Since this bottle has a cylindrical shape, when gas is generated and the internal pressure increases, the lower part of the bottle bulges outward, so the state was evaluated according to the following criteria. ◯: No change (bottom part of bottle remains indented) Δ: Bottom part of bottle is slightly swelled and becomes flat. X: The lower part of the bottle swells and the bottle tilts. (Or fall.)
