Description

Cleaner Composition Having Bleaching Effect

The present invention relates to a cleaning composition having a bactericidal and disinfectant, and in particular, to a disinfectant and disinfectant in a liquid phase containing an arylsulfonate salt which improves the bubble power of the surfactant together with the bactericidal and disinfectant compound containing hypochlorite ions. It relates to a composition.

In general, hypochlorite has been used for the purpose of disinfecting and disinfecting. In particular, hypochlorite is mixed with a surfactant to disinfect and disinfect as well as to disinfect and disinfect. It can be very effective.

However, if the area to be sterilized and disinfected and decontaminated is a vertical plane, the sterilization and cleaning components stay on the vertical plane for a short time, so it is insufficient to expect sterilization and disinfection as well as a cleaning effect.

In addition, even when using a bubble-type spray gun to improve the ease of use when used in a vertical plane, the foaming power is weak, not only does not have a good vertical adhesion effect of sterilization and cleaning ingredients, but also the contents are fine when sprayed with a bubble-type spray gun. Blowing up causes problems of skin irritation and discoloration during fabric contact. This is because the surfactant has a lower solubility in hypochlorite solution and thus the foaming ability is lowered.

The present invention is to solve the above problems, an object of the present invention is to provide a detergent composition that is capable of improving the bubble forming ability and to increase the vertical contact time of the detergent component as possible.

Disinfectant and disinfectant cleaning composition of the present invention for achieving the above object, hypochlorite 0.1 to 10% by weight, anionic surfactant 0.05 to 8% by weight, nonionic surfactant 0.05 to 8% by weight, arylsulfonate salt 0.1 to 20% by weight, inorganic salts containing 0.05 to 10% by weight and the balance of water.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

The present invention is due to the fact that when the mixture of the surfactant and the arylsulfonate salt is used, the foaming ability is improved and the vertical adhesion function is excellent when the bubble type spray gun is used. Cleaner composition having a, 0.1 to 10% by weight hypochlorite, 0.05 to 8% by weight of anionic surfactant, 0.05 to 8% by weight of nonionic surfactant, 0.1 to 20% by weight of arylsulfonate salt, 0.05 to 10% by weight of inorganic salt % And the balance of water.

Such cleaning composition of the present invention uses hypochlorite ions in alkaline aqueous solution as an active ingredient for sterilization and disinfection. The hypochlorite usable in the present invention may refer to alkali metal or alkaline earth metal salts of hypochlorous acid, and specific examples thereof include sodium hypochlorite, potassium hypochlorite and magnesium hypochlorite. Among these, sodium hypochlorite is the most preferable. In addition, sodium hypochlorite is mostly in the form of a solid or concentrated liquid or an aqueous solution dissolved in water. An aqueous solution phase is preferable for use in the present invention.

The hypochlorite is used in the range of 0.1 to 10% by weight, preferably 0.2 to 6.0% by weight, but when used at less than 0.1% by weight, it is difficult to function as a disinfectant and disinfectant. This is not good and disadvantageous in terms of the stability of the hypochlorite ion itself.

The anionic surfactants are mainly intended for the cleaning effect and bubble formation. Since most of the anionic surfactants act as a factor for decomposing hypochlorite, the anionic surfactant used in the present invention is hypochlorite. Excellent compatibility with, alkyl ether sulfate represented by RO- (CH ₂ CH ₂ O) _n -SO ₃ M, alkanesulfonate represented by R'SO ₃ M, alkyldiphenyl of formula Ethersulfonates may be used alone or in combination (where R represents C ₁₂ to C ₁₄ alkyl and R ′ represents primary or secondary C ₁₀ to C ₁₈ alkyl).

(Where R 'represents C ₈ to C ₁₄ alkyl, n represents an integer of 3 and M represents sodium or potassium.)

The amount of the anionic surfactant is used 0.05 to 8% by weight. If the amount is less than 0.05% by weight, not only the cleaning power of the contamination is very weak but also the foaming power is very weak, and the use of more than 8% by weight reduces the stability to hypochlorite ions.

In addition, it is more effective to use a nonionic surfactant alkyl (C ₁₂ ~ C ₁₄ ) dimethylamine oxide as a fine preparation of the anionic surfactant. The amount of the alkyldimethylamine oxide is used is 0.05 to 8% by weight. If it is used less than 0.05% by weight, it is weak in the detail information, and when used more than 8% by weight deteriorates the stability to hypochlorite ions.

On the other hand, when the surfactant is used alone, the formation of the foaming force in hypochlorous acid solution is very weak, but when used in combination with the arylsulfonate salt, the foaming force is very high, it is excellent adhesion to the vertical plane when spraying with a bubble-type spray gun.

In addition, the arylsulfonate salt used in the present invention has excellent storage stability, and has an advantage of excellent storage stability even when compared to a surfactant having the same content.

The arylsulfonate salt is a derivative of benzene or naphthalene, and the arylsulfonate salt used herein can be used alone or in combination thereof with xylenesulfonate salt, toluenesulfonate salt, cumenesulfonate salt and the like. Salts (M) of the arylsulfonate salts are sodium and potassium.

The amount of arylsulfonate salt used is 0.1 to 20% by weight. If the amount is less than 0.1% by weight, the effect of bubbles is insufficient. If the amount is more than 20% by weight, the stability to hypochlorite ions is lowered.

In the present invention, it is preferable that the mixing ratio of the surfactant and the arylsulfonate salt is set to 1:10 to 10: 1 of the surfactant: arylsulfonate salt.

The inorganic salt is for maintaining the alkalinity of the composition, and specific examples thereof may be used alone or in combination with sodium carbonate, sodium bicarbonate, sodium silicate and the like. The content thereof is 0.05 to 10% by weight, preferably 0.1 to 8% by weight. The type and amount of inorganic salt used is chosen to maintain the composition pH between 10.0 and 14, preferably between 10.5 and 13.5, wherein maintaining the pH above 10 is not only an important factor in polarizing the chemical stability of the composition, It is also a factor to improve the decontamination ability of the surfactant. Maintaining the pH of the composition at 10-14 also helps to minimize chemical degradation of the hypochlorite compound in aqueous solution and to minimize chemical interaction between the hypochlorite compound and the surfactant. However, transition metal salts tend to decompose hypochlorite ions in aqueous solution, so it is better to avoid their use.

Water serves as a medium for dissolving soluble materials in one place. When calcium or magnesium ions are present in water, the cleaning power of the surfactant is reduced. Contamination metals, particularly copper, cobalt, and nickel, It is preferable not to contain such metal ions since it promotes decomposition of chlorate ions. Preferably soft water or deionized water is used.

In addition, as described above, since the pH of the composition according to the present invention is preferably maintained at 10 to 14, when the pH of the prepared composition is not within this range, it may be adjusted to a desired pH by additionally using a pH adjusting agent. Preferred pH adjusting agents include sodium hydroxide and potassium hydroxide.

The cleaning composition of the present invention having such a composition exhibited an excellent bubble forming effect when using a bubble type spray gun.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, these examples are only for the understanding of the present invention, and the scope of the present invention in any sense is not limited to these examples.
