Description

Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 4i259C A7 ________ B7 V. Description of the invention (1) Background of the invention The invention relates to a liquid bleaching composition filled in a flexible packaging bag and more particularly during storage. In a flexible bag that will not swell or crack. Prior art bleaching agents have been divided into two categories, namely chlorine-based bleaches and oxygen-based bleaches. Air-type bleaching agents can be used on limited fibers and cannot be used on colored or patterned textiles and emit strange odors. Oxygen-based bleaches without these disadvantages have recently expanded significantly. Among the oxygen-type bleaches, sodium percarbonate and sodium perborate have been used as powder bleaches and hydrogen peroxide has been used as a liquid oxygen-type bleach. With regard to ease of use in particular, liquid bleaching compositions have gained popularity. The liquid bleaching composition generates oxygen during storage because hydrogen peroxide, which acts as a bleach activator, lacks stability. The container used for the liquid bleaching composition, therefore, has a strong structure as disclosed in JP-A-4-220499. Because of issues such as retaining natural resources and discarding plastic waste, however, the demand for refilling liquid bleach filled in bags made of thin plastic films has grown in recent years. As specific examples of the plastic substance packaging bag for refilling the bleach, the packaging materials disclosed in JP-A-505322 and JP-U-3-123847 can be cited. However, these packaging materials have problems with significant swelling or cracking during storage. This problem is based on the instability of hydrogen peroxide in light. In order to avoid this problem, it is possible to make the packaging bag of plastic material to obtain the concept of truncated light! .--- ^ ------ Packing ------- Order ------ Travel (Please read first Note on the back, please fill in this page again.)

A method including forming a metal layer such as an aluminum layer on the inner surface of a multilayer wall of a plastic container and a method of staying to form a gray ink layer can be cited as specific examples of the above concept. These plastic containers still lack storage stability. Because liquid bleaching agents are often incorporated with nonionic surfactants as a cleaning agent component, the disadvantage is that the nonionic surfactants suffer from penetrating into the resin layer of the plastic substance container and eventually degrading the container or making the container surface sticky. The aim is therefore to provide a liquid bleaching composition which is filled in a flexible packaging bag and which is free from the disadvantages described above. The inventor, after diligent research and looking forward to solving the above-mentioned problems of the prior art, found that the above-mentioned g standard is filled with a specific liquid bleaching composition in a flexible packaging bag made of light-cut plastic material or paper Reached. As a result, the present invention has been completed. SUMMARY OF THE INVENTION The present invention provides a liquid bleaching composition filled in a flexible packaging bag, which is an acidic liquid bleaching composition, including: (a) 0.5 to 50% by weight of a non-ionic surfactant with HLB in the range of 5 to 10, as determined by Mr. Davis' method and represented by formula (1): Rl-X- (AO) mY (1) where R1 represents a linear or Branched alkyl or fluorenyl or as appropriate!
