JP2935194B2 - Aerosol foaming detergent composition - Google Patents

Description

The present invention relates to an aerosol foaming detergent composition which is excellent in detergency and foaming property, has no irritation, and does not cause whitening after washing and drying. In particular, the present invention relates to a foamable detergent composition for aerosol which is suitable for cleaning a net surface such as a screen door.

[Conventional technology]

As foaming detergent compositions for aerosols, there have heretofore been known those comprising one type of surfactant or those comprising a combination of a plurality of types of surfactants.

However, this type of composition has the disadvantages that it has poor detergency, poor foam continuity, and poor rinsing properties.

Further, a detergent composition comprising coconut oil soap alone is also known, but this has a drawback that it is highly irritating, does not have sufficient detergency or foaming property, and further causes whitening after washing and drying. .

[Problems to be solved by the invention]

The conditions of the aerosol detergent composition required for cleaning a complicated surface such as a screen surface of a screen door include the following.

(1) The cleaning power is large.

It is necessary to have a detergency to remove dirt in about 5 minutes after spraying the aerosol.

(2) Excellent foaming properties.

Foaming means foaming power and foam stability. Since the cleaning power is maintained until the bubbles disappear, the cleaning effect is enhanced, and the amount of detergent used is small, and waste is eliminated. In particular, it is very important that stable foam adheres evenly when cleaning complicated surfaces such as mesh surfaces.If the fineness of the foam and the foam spreading property are poor, the foam may pass through the mesh or defoam. Do not serve the purpose of cleaning.

(3) No irritation.

The lack of irritation in aerosol detergents is particularly important.

(4) Do not cause whitening.

After the aerosol is rinsed off with water and dried, it is necessary that whitening does not occur on the surface to be cleaned such as a mesh surface or the floor surface on which the cleaning water has flowed.

SUMMARY OF THE INVENTION An object of the present invention is to satisfy all of the above-mentioned conditions (1) to (4) and to improve the disadvantages of the above-mentioned known technology, and particularly to a foaming detergent for aerosol suitable for cleaning a net surface such as a screen door. It is to provide a composition.

[Means for solving the problem]

In order to achieve the above object, according to the foamable detergent composition for aerosol according to the present invention, a higher alcohol ether sulfate triethanolamine salt (A), a higher alcohol ethylene oxide adduct (B), and a fatty acid alkanolamide (C), wherein the mixing ratio of the components (A), (B) and (C) is (A) :( B):
(C) = 1: 2-6: 1-4.

The aforementioned higher alcohol ether triethanolamine sulfate (A) has the general formula _{R-O- (CH 2 CH 2} O) n SO 3 HN (C 2 H 4 OH) 3 ( provided that, R: 11 to 15 carbon atoms Alkyl group, n: 1 to 7), specifically, Emal 20T (R: C
₁₂ , n = 3) (manufactured by Kao Corporation).

In addition, the higher alcohol ethylene oxide adduct (B) is specifically represented by the general formula R—O— (CH ₂ CH ₂ —O) _n H (where R is an alkyl group having 11 to 18 carbon atoms, n: 3 ~ 20).

Further, the lipoic acid alkanolamide (C) is specifically And so on.

The mixing ratio (A) :( B) :( C) of these components (A), (B) and (C) is 1: 2 to 6: 1 to 4, preferably 1: 3 to 5: If the ratio is from 1 to 3, it is impossible to maintain good washing, foaming, irritating and whitening properties.

In the present invention, any suitable amount of an organic chelating agent, a hand roughening inhibitor, a fragrance, etc. can be used in addition to the components (A), (B) and (C).

Examples of the organic chelating agent include hydroxycarboxylates, for example, oxalate, lactate, hydroxyacetate, succinate, malate, tartrate, citrate, gluconate, and the like, polymeric phosphates, such as Aminocarboxylates such as pyrophosphate, tripolyphosphate, tetrapolyphosphate, metaphosphate, etc., such as NTA (nitrilotriacetate), E
Aminophosphonates such as DTA (ethylenediaminetetraacetate), HEDTA (hydroxyethylethylenediaminetriacetate), and DTPA (diethylenetriaminepentaacetate);
HEDP (1-hydroxyethane 1,1-diphosphonate), ATMP (aminotrimethylene phosphonate), EDTM
P (ethylenediaminetetramethylenephosphonate)
And polycarboxylates, for example, polyacrylates, copolymers of acrylates and maleates, and the like.

Examples of the hand roughness preventing agent include dimethylalkylamine oxide, bis (2-hydroxyl) alkylamine oxide, and the like.

The composition of the present invention thus obtained is diluted to a desired concentration of about 10 to 15% with a solvent such as water at the time of use.
It contains propellant of about volume% and is adjusted as aerosol detergent. The above-mentioned propellant is optional, and as an example, LPG is used and the gas internal pressure is 4.2 kg.
/ cm ² (25 ° C).
