Description

The present invention is a detergent composition used in the form of an aerosol for cleaning screen doors, air conditioner filters, window glass, ventilation fans, toilets, bathtubs, automobiles, etc., and has sufficient cleaning power and foaming power. Further, the present invention relates to an aerosol foaming detergent composition that suppresses after-drawing.

Conventionally, screen doors have been washed by a method such as rubbing with a sponge or scrubbing brush, or a method using a commercially available cleaning agent. However, the method of rubbing with a sponge or the like may damage the mesh surface or cause sagging. Therefore, as a screen cleaner, it is necessary to use a cleaning agent that has a high cleaning power that removes dirt without rubbing. In particular, foamability is important so as not to pass.
Aerosols that inject bubbles tend to increase the amount of after-draw that accumulates in the vicinity of the button nozzle after spraying.In particular, the longer the distance from the stem to the tip of the nozzle, the more bubbles are generated, and the bubbles fall into the container. There was a problem of sticking or sticking to the hand.
There is also a proposal of an aerosol foaming detergent composition (Japanese Patent Laid-Open No. 4-13800) which is excellent in detergency and foaming properties and is not irritating, but it was insufficient due to a large number of after-draws.
There is also a proposal of an aerosol composition (Japanese Patent Laid-Open No. 3-292386) containing one or two or more selected from a specific silicone oil and a branched hydrocarbon and a branched ester oil that are liquid at room temperature. Therefore, there is a problem that an oily component remains on the cleaning surface and sufficient cleaning power cannot be obtained.
We have also proposed a weak alkaline screen door cleaning composition (JP-A-10-265800) having a pH of 8 to 11, but the present invention aims to improve the adhesion rate of bubbles. Although the adhesion rate of the foam was improved, it was not an improvement of after-drawing.

An object of the present invention is to provide an aerosol foaming detergent composition having sufficient detergency and foaming power, and further suppressing after-drawing.

In order to solve the above problems, the present invention employs the following configuration.
(1) (A) Fatty acid soap 0.5-5% by weight, (B) Surfactant 0.5-5% by weight, (C) Metal ion sequestering agent 0.5-6% by weight, (D) Water-soluble Solvent 0.5 to 20% by weight, (E) 0.02 to 0.2% by weight of antifoaming agent, (F) 82 to 92% by volume of cleaning liquid containing ion-exchanged water as propellant An aerosol foaming detergent composition in which after-drawing is suppressed by filling LPG having a pressure at 20 ° C. of 0.23 to 0.50 MPa with 8 to 18% by volume.
(2) The foaming detergent composition for aerosol which suppressed the after-draw as described in (1) whose antifoaming agent is a silicone type antifoaming agent.
(3) When used for cleaning a screen surface of a screen door or an air conditioner filter, the foam adherence rate to the screen surface is 70% or more. Foaming detergent composition.

Since the foamable detergent composition for aerosol of the present invention has high detergency and foaming power and further suppresses after-drawing, the usability is good, and its practicality is extremely high.

The fatty acid soap of component (A) used in the present invention may be either saturated or unsaturated, and those having 8 to 22 carbon atoms, particularly 10 to 18 carbon atoms are preferred. Specific examples include alkali metal salts such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, coconut oil fatty acid, and beef tallow fatty acid, ammonium salts, and amine salts. Among these, sodium laurate, potassium laurate, coconut oil fatty acid sodium, and coconut oil fatty acid potassium are particularly preferable. These fatty acid soaps can be used alone or in combination of two or more, and are blended in the cleaning liquid in an amount of 0.5 to 5% by weight, preferably 1 to 3% by weight. If it is less than 0.5% by weight, sufficient detergency and foam performance cannot be obtained, and if it exceeds 5% by weight, the foam scatters more and causes inconvenience.

The surfactant of component (B) may be any of anion, nonion, and amphoteric surfactant that are usually used in liquid detergents. Examples of the anionic surfactant include alkylbenzene sulfonate and linear alkylbenzene. Examples include sulfonate, alkyl sulfate, α-olefin sulfonate, alkyl phosphate ester salt, polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl phenyl ether sulfate, polyoxyethylene alkyl ether phosphate, and the like. Examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, fatty acid alkanolamide, and amine oxide. Examples of the amphoteric surfactant include alkyl carboxybetaine type, alkyl Minokarubon acid type, and the like alkyl Your da ethylbenzthiazoline type. These surfactants can be used alone or in combination of two or more, and are blended in the cleaning liquid in an amount of 0.5 to 5% by weight, preferably 1 to 2% by weight. If it is less than 0.5% by weight or more than 5% by weight, problems such as poor foaming occur.

Examples of the sequestering agent of component (C) include organic acids such as citric acid, malic acid and succinic acid and salts thereof, aminocarboxylic acids such as ethylenediaminetetraacetic acid, hydroxyethylenediaminetriacetic acid and nitriloacetic acid and salts thereof, Examples include polymer carboxylates such as sodium polyacrylate. Examples of the salt include alkali metal salts such as sodium and potassium, ammonium salts, and amine salts. Of these, sodium citrate is particularly preferable. These sequestering agents can be used alone or in combination of two or more, and are blended in the cleaning liquid in an amount of 0.5 to 6% by weight, preferably 2 to 4% by weight. If it is less than 0.5% by weight, sufficient detergency cannot be obtained. On the other hand, if it exceeds 6% by weight, the foamability is deteriorated, resulting in inconvenience.

Examples of the water-soluble solvent of component (D) include alcohols, polyhydric alcohols and derivatives thereof, specifically, ethanol, isopropyl alcohol, ethylene glycol, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monoethyl ether. , Diethylene glycol monobutyl ether, propylene glycol, propylene glycol monoethyl ether, propylene glycol monobutyl ether, dipropylene glycol monoethyl ether, dipropylene glycol monobutyl ether and the like. Of these, ethanol and isopropyl alcohol are particularly preferable. These water-soluble solvents can be used alone or in combination of two or more, and are blended in the cleaning liquid in an amount of 0.5 to 20% by weight, preferably 5 to 18% by weight. If it is less than 0.5% by weight, sufficient detergency and foam performance cannot be obtained, and if it exceeds 20% by weight, foam scattering increases, resulting in inconvenience.

The component (E) may be any antifoaming agent that is uniformly dispersed in the cleaning liquid and exhibits an antifoaming effect, such as a silicone-based antifoaming agent, a fatty acid ester-based antifoaming agent, and a higher alcohol-based antifoaming agent. Examples thereof include foaming agents and polyether antifoaming agents. Of these, silicone antifoaming agents are preferred. These antifoaming agents can be used alone or in combination of two or more, and are blended in the cleaning liquid in an amount of 0.02 to 0.2% by weight. If it is less than 0.02% by weight, the amount of after-draw increases, and if it exceeds 0.2% by weight, foaming is worsened to cause inconvenience.

The propellant used in the present invention is filled with LPG having a pressure at 20 ° C. of 0.23 to 0.50 MPa in an amount of 8 to 18% by volume, preferably 0.28 to 0.45 MPa in an amount of 10 to 15% by volume. The If the pressure is less than 0.23 MPa or less than 8% by volume, problems such as poor foaming and after-drawing will occur, and if the pressure exceeds 0.50 MPa or more than 18% by volume, bubbles will fly out. Produce.

Moreover, you may mix | blend a pH adjuster, a disinfectant, a deodorant, an insect repellent, a fragrance | flavor, etc. with the foaming detergent composition for aerosols of this invention further suitably.

The injection button used in the present invention may be any button that forms bubbles, but the distance from the stem to the tip of the injection port is preferably 5 to 50 mm. If it exceeds 50 mm, inconveniences such as an increase in the number of afterdraws in which bubbles accumulate in the vicinity of the nozzle nozzle are caused.
