Description

A7 B7 Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. 5. Description of the invention (1) The present invention is a liquid bleach composition for clothes, kitchens, and hard surfaces. More detailed information is about the bleaching effect when used alone. At the same time, those who have a bleach composition with a stable liquid with high hydrogen peroxide. The bleaching agent is classified into a chlorine-based bleaching agent and an oxygen-based bleaching agent, and the oxygen-based bleaching agent has the characteristic that it can be used for colored clothes. Oxygen-based bleaching agents are characterized by powder and liquid. The liquid is well known for its convenience and ease of use. It is widely used as the mainstream of bleach for clothing. The main bleaching base of this oxygen-based bleaching agent is hydrogen peroxide. This bleaching power is inferior to that of chlorine-based bleaching agents, so there is a problem of improvement. Another problem is the stabilization of hydrogen peroxide. Hydrogen peroxide is ergonomic and usually produces oxygen after its own decomposition. Therefore, the liquid oxygen bleaching agents currently on the market are adjusted to be acidic. However, the bleaching effect of hydrogen peroxide is higher than that under acidic conditions, so it is usually used in combination with lotions. That is, the subject that a high bleaching effect can be exhibited even when used alone. Therefore, it is necessary to stabilize the hydrogen peroxide at a higher pH to make the product before it can be safely put on the market. Therefore, in view of the lack of the foregoing prior art, the present invention aims at providing a liquid bleaching composition which has excellent storage, stability, and can achieve high-efficiency bleaching effect without using lotion (alkaline). That is, the present invention is to provide (a) 0.1 to 30% by weight of hydrogen peroxide (b) phenylhydrazone or its derivative 0.01 to 6% by weight (c) boron compound 0.1 to 30% by weight Standard (CNS) A4 specification (210 X 297 mm) -4------------- • lacquer-• J / ·-*-* ..

A7 ___________B7 of the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs B7 V. Description of the Invention (2) (d) Liquid bleach composition characterized by polyalcohol compounds. Hereinafter, the present invention will be described in more detail. The amount of hydrogen peroxide used as the component (a) of the present invention is 0.1 to 30% by weight, and preferably 1 to 10% by weight. The phenol or its derivative used as the component (b) of the present invention has the effect of inhibiting the decomposition of hydrogen peroxide. Its blending amount is 0.001 to 6% by weight, preferably 0.1 to 5% by weight. When the blending amount is less than 0.01% by weight, the effect of suppressing the decomposition of hydrogen peroxide is insufficient. On the other hand, when it is more than 6% by weight, the stability of the preparation is poor, which is likely to cause crystal precipitation and liquid separation. The phenol derivative is preferably a compound having a phenolic fluorenyl group, or an ester derivative or an ether derivative of a phenolic fluorenyl group. Among them, those having a phenolic oxo group are more preferable. Among them, preferred compounds are those contained in GE Penketh, J. Appl. Che-m, 7, 5 1 2 (1957) whose redox potential (O. P.) is 1.25V or less, more preferably 0. Below 9 5 .V, the most ideal is below 0.7 5 V. More desirable phenol derivatives are effective in smaller amounts. In addition, these compounds may be used singly or as a mixture of plural compounds. Among them, those with better effects include dimethoxyphenol, catechol, and hydroquinone. Representative compounds No. 1 to No. 29 shown in Table 1 below are taken as specific examples. 0 ~ 3 0% by weight, please read it first.
