Description

DETAILED DESCRIPTION OF THE INVENTION (Fields of application of Product T:1) The present invention is applicable to bleaching of fibers, removing various bacteria, alleviating rotting folds (organic matter), etc. Washing,
It relates to bleach compositions for household and commercial use for sanitary purposes. And, the present invention:
This bleaching agent contains i1+i chlorate as a main component, and is characterized by improved viscosity and detergency, as well as superior odor mitigation.

(Prior Art) A technique for imparting viscosity to the following I++r chlorate bleach composition itself is described in, for example, Japanese Patent Application No. 58-234009 filed by the same applicant as the present invention. This is a bleaching agent that basically contains a specific Seviolite mineral and two types of surfactants.

In addition, the use of sodium aralsulfonate as a surfactant for hypochlorite was published in Japanese Patent Publication No. 43-24786.
It is stated in the publication No.

The use of alkyldimethylamine oxide is disclosed in Japanese Patent Application Laid-open No. 56-90897 and Japanese Patent Publication No. 45-7070.
Furthermore, the use of these together in some form is described in JP-A-55-500!17 and JP-A-57-61099, each of which belongs to the known technology. It is something.

Inorganic substances such as tripolyphosphoric acid and silicates, polycarboxylic acid salts (acrylic acid, maleic acid, etc.), as well as gianthan gum and locust bean gum.

The same applies when a rubbery material 2 such as gum arabic or gum karaya is used. In addition, trichloride (primary subsalt) is a strong acid aqueous substance, is alkaline, and has strong hydrolysis power, and can be used for a long period of time in a wide temperature range of -10℃ to 50℃, reducing the amount of available chlorine. It was extremely difficult to prevent this from happening.

Furthermore, the use of sodium argylsulfonate as a surfactant in the above-mentioned hypochlorite, the use of alkyldimethylamine oxide, and the combined use of these in some form, all of which What the techniques have in common is the penetrating power and the bleaching blade.I:

Incidentally, regarding odor improvement, as described in Japanese Patent Application Laid-open No. 52-60445, there have been products that simply incorporate fragrances.

The present invention is an attempt to solve the above-mentioned conventional problems, namely, a new bleaching agent composition that has excellent bleaching blades, excellent cleaning power, and is easy to use with improvements in odor and viscosity problems.

Evaluation method % formula % O: Slight chlorine folds are felt □ ×: Chlorine odor is felt (Example) A detailed explanation of the concrete practice of the present invention tM@ is as follows.

The present invention applies to an aqueous solution of the next rnr chlorate, which is designed to preferably contain about 1 to 7.5% of available chlorine and sodium chloride as a blended metal within 1.5% of the aqueous solution of hypochlorite. As a surfactant, 5SA (alkyl sulfonate) and AO (alkyl dimethylamine oxide) are used in a specific ratio, and an alkaline substance, especially sodium hydroxide, is blended at about 0.1 to 4%. This patent is characterized by:

The present invention relies on this, viscosity, stability, detergency, transparency,
This makes it possible to produce a bleach composition that is improved in terms of odor.

In other words, sodium hypochlorite itself has about 12% available chlorine, and if sodium chloride is used within at least 2%, preferably within 1.5%, it can be used as a surfactant. The SSA to be used is an alkali salt (preferably soda salt) containing at least 70% monosulfonic acid obtained by converting secondary paraffin with chlorosulfonic acid, and a linear alkyl type one in which the alkyl of AO is C0 to C8, and is made into 5SAI. A total of 2 to 8 (wt%) of AO at a ratio of 0.7 to 4.4 times the amount of
．． A bleaching agent obtained by blending 0 to 4 (by V%) is a constituent element.

Conventionally, sodium hypochlorite, sodium chloride, sodium pyrophosphate, and sodium acrylate were used.

It has been common practice to use products containing salts such as sodium carbonate and sodium silicate.

Although it is widely known that reducing the sodium chloride in primary sodium hypochlorite stabilizes the available chlorine itself, it does not contribute to the desired viscosity improvement.

The present invention uses only low salt (sodium chloride) mizuhiki (sodium chlorate) and, as a surfactant, an alkali metal salt (C~C1#) of a secondary paraffin sulfonated by the chlorosulfonation method. Na, K, etc.)
It has been found that when blended with dialkyl sumine oxide in a specific ratio, it exhibits thickening, stability, and odor improving effects.

SSA produced by the chlorosulfonation method produces 3 to 5% sodium chloride as a byproduct, but this small amount of halogenated molecules (chlorine) coexists with hypochlorite and contributes to viscosity and stability. This is why sulfuric anhydride is like fuming sulfuric acid! Substances containing sodium chloride do not solubilize and lack stability over time. The SSA has the general formula R-3O,M (R is CIs "C-a"), or 1M
is Na, K, N114. These are alkanolamine residues such as monoethanolamine, triethanolamine, and monoisopropanolamine. ), furthermore, the second R
Sulfonation of paraffin reduces viscosity unless SSA contains at least 70% monosulfonic acid. B and ν, which contain a large amount of disulfonic acid, have excellent resistance to hydrolysis and oxidation, but cannot be expected to have the desired effects of the present invention.

On the other hand, the alkyldimethylamine oxide used in combination,
It is expressed by the following general formula.

When is higher than Cps, it is possible to suppress the excessive foaming property of SSA, so that it can be used for applications where foaming is not preferred.

For SSA and AO, the former is 1 (heavy 1), while the latter is 0.
It is necessary to mix in a ratio of 7 to 4.4 (weight), preferably 0.8 to 4. In particular, SSA should be less than 2.5% in the composition.

This is because if you close the lid, the liquid will become cloudy or crystallize and lose its stability.

In any case, in order to maintain P[I at 11 or more, an alkali metal hydroxide salt, particularly soda salt, potassium salt, etc., is used in an amount of 0.1 to 4%, preferably 0.1 to 3%. This is necessary to ensure the stability of hypochlorite. In addition to the above, the composition of the present invention also includes various fragrances, dyes, binders, fluorescent agents, bactericides, salts (halogenated salts, phosphates, silicates, borates, carbonates, organic acid salts, etc.), abrasives (polymers, etc.) ,
