Description

A7 B7 Consumption cooperation between employees of the Central Bureau of Standards, Ministry of Economic Affairs, Du Yinhe 416S86 V. Description of the invention (1) Background of the invention Fan Yuan: The present invention is a liquid bleach composition for strengthening viscosity and more specifically 1 for obtaining excellent A liquid bleach composition that is stable in storage and is subject to enhanced viscosity with only minor viscosity changes due to temperature changes. Explanation of previous techniques: Bleaching agents are classified into two types, namely chlorine-based bleaching agents and oxygen-based bleaching agents. Chlorine-based bleaching agents can only be used on a limited number of fibers, they cannot be used on colored or patterned fabrics, and they are rejected due to their special odor. Therefore, oxygen-based bleaching agents, which do not have these disadvantages in recent years, have been significantly promoted. Among the oxygen-based bleaches, sodium percarbonate and sodium perborate are used as powder bleaches and hydrogen peroxide is used as a liquid oxygen-based bleach. From the standpoint of ease of use, liquid bleach compositions are preferred over other types of bleach compositions. When a liquid bleach is used to bleach clothes, it is often placed directly in the washing machine. However, when it is directly applied to the stain, it shows a high bleaching effect. Because the general liquid oxygen-based bleaching sword has a low viscosity ′, when it is applied to a stain on scale clothes, it moves from the stain before the paint is made into the stain. Therefore, from the standpoint of ease of use, such an application is problematic. In such cases, a liquid bleach improved by enhanced viscosity has been required. As a method to strengthen the viscosity of liquid bleaching agents, the World Intellectual Property Organization ___ -4- This paper applies the Chinese National Standard (CNS) A4 Regulations-Standard (21GX297 Gongchu) — ~~ — ------ (Please read first Note on the back then fill out this page}

A7 B7 416S86 V. Description of the invention (2) Patent 9 4/1 14 7 4 discloses a method relying on the use of two non-ionic surfactants' and US Patent-A 4900469 discloses a method relying on a combination of a fatty acid. However, when these methods are applied to acid liquid bleaching agents, due to the related bleaching agents, they undergo significant viscosity changes due to temperature changes, so these methods raise the problem that bleaching agents are practically only difficult to use. The Japanese patent-A-2-300300 discloses an acid-concentrated liquid component which uses a copolymer of an unsaturated polyacid and an olefinic monomer and a monomer as a thickener. The use of such thickeners not only causes the liquid components to suffer significant viscosity changes due to temperature changes, but also causes thickeners, when applied to include a bleach activator such as disclosed in Japanese Patent _A_6_494 87 In a liquid bleach composition, the problem of accelerated decomposition of the bleach activator. In addition, it is conceivable to use polysaccharides such as xanthan gum and polygalactomannose and cellulose derivatives such as carmellose as thickeners. However, these thickeners have the problem that they cause decomposition of hydrogen peroxide when stored. SUMMARY OF THE INVENTION Accordingly, one of the items of the present invention is to provide a liquid bleaching composition that enhances viscosity, which eliminates the shortcomings of the prior art described above, and is good at storage stability and suffers from only small viscosity due to temperature changes. change. After diligent research, the present inventors have found that the above-mentioned object is achieved by combining a specific polyoxyalkylene derivative as a thickener, and has reached the present invention. In particular, the present invention is directed to a liquid bleach composition for enhancing viscosity, which comprises hydrogen peroxide, a thickener, and a surfactant-5.
