Abstract

<P>PROBLEM TO BE SOLVED: To provide a foam-like spray type outdoor detergent with easy usage having a sufficient washing power and having less dropping/flowing such that the detergent is firmly applied to a contaminant even to a vertical surface such as a wall when a moss plant and a mold staining generated on a door porch and a yard and a scale staining of a wall surface are washed. <P>SOLUTION: The foam-like spray type outdoor detergent having pH of 3.1-4.2 contains (A) 1-10 wt.% of malic acid, (B) 1-5 wt.% of non-ionic surfactant, (C) 0.5-5 wt.% of amphoteric surfactant, and (D) 0.5-3 wt.% of sodium polyacrylate and water (100 wt.% as a whole), and is filled in a spray type vessel and is used. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

A detergent composition that is used by filling a spray container that is easy to use when cleaning moss, mold stains, scale stains, etc. generated around the entrance and garden. The present invention relates to a foam-type spray-type outdoor cleaning agent that has a little sagging flow so that the cleaning agent can act firmly on dirt even on the vertical surface of the.

For moss, mold stains and scale stains generated around the entrance and around the house, there are extremely few cases of washing detergent with a strong water pressure such as a jet washer and special detergents on the market. There are many cases where detergent is substituted. However, it is not easy to use with a jet washer. Chlorine bleaching agents are likely to cause discomfort due to the odor of chlorine, reversion, and effects on plants. It is difficult to obtain a satisfactory cleaning effect with something like a kitchen detergent.
In consideration of these problems, an outer wall cleaning agent (see Patent Document 1) in which an organic acid, a specific acid, and a surfactant are combined has also been proposed for the purpose of cleaning power.
JP-A-10-306300

However, when this outer wall cleaning agent is used on a wall surface, the cleaning component drips down and the action on dirt is insufficient, and neutralization treatment with an alkaline solution is required, so that it lacks simplicity.
In the present invention, it is easy to use from the above situation, it has excellent detergency, and it is a foam-type spray-type outdoor that has a low deterrence flow so that the cleaning agent acts firmly on dirt even on a vertical surface such as a wall surface. It is an object to provide a cleaning agent.

As a result of repeated studies to achieve the above object, the present inventors have achieved excellent detergency by blending malic acid, nonionic surfactant, amphoteric surfactant and polyacrylic acid soda at a specific ratio. In addition, it has led to the development of a foam spray-type outdoor cleaning agent that has a dripping flow on the vertical surface by being foamed during spraying.

That is, the present invention comprises (A) 1-10% by weight of malic acid, (B) 1-5% by weight of nonionic surfactant, (C) 0.5-5% by weight of amphoteric surfactant, (D) poly What is provided is a foam spray type outdoor cleaning agent characterized by containing 0.5 to 3% by weight of sodium acrylate and water (100% by weight as a whole) and having a pH of 3.1 to 4.2 It is.

The amount of malic acid component (A) used in the present invention is 1 to 10% by weight, preferably 3 to 7% by weight, based on the entire composition. If this amount is small, the acid washing effect and chelate effect are not exhibited. If the amount is too large, the pH will be too low, which may adversely affect the outer wall material or planted trees.

As the nonionic surfactant of component (B), those usually used for liquid detergents may be used, and examples thereof include polyoxyethylene alkyl ether, fatty acid alkanolamide, and amine oxide. Among these, polyoxyethylene alkyl ether is particularly preferable, and 1 to 5% by weight is blended in the composition, preferably 1.5 to 3.5. If this amount is small, effective detergency cannot be exhibited, and if it is too large, there is no improvement point, which is economically disadvantageous.

Examples of the amphoteric surfactant of component (C) include alkylcarboxybetaine type, alkylaminocarboxylic acid type, alkylimidazoline type and the like. Among these, the alkylcarboxybetaine type is preferable, and 0.5 to 5% by weight is blended with respect to the entire composition.
A preferable blending ratio of the component (B) and the component (C) is a weight ratio, and the component (B): component (C) = 2.5: 1 to 1: 1. If the amount of component (C) is small, foaming is poor when sprayed, and if too much, improvement of foaming is not seen, which is economically disadvantageous.

The molecular weight of the sodium polyacrylate of component (D) is preferably 5000 to 10,000, and the blending amount is preferably 0.5 to 3% by weight based on the entire composition.
A preferable blending ratio of (B) component + (C) component and component (D) is a weight ratio, and the ratio of (B) component + (C) component: (D) component = 5: 1 to 2: 1. is there.
If the blending amount of component (D) is too small or too large, the foam adherence deteriorates, and the contact time between the cleaning agent and the dirt cannot be sufficiently secured on the vertical surface.

The pH of the cleaning composition of the present invention needs to be 3.1-4.2. If the pH is too low, there is a problem in terms of safety, which is not preferable. If the pH is too high, a sufficient cleaning effect cannot be obtained. As means for adjusting the pH, it is preferable to use malic acid, citric acid or salts thereof.

In addition, fragrances, dyes, preservatives, bactericides, anti-redeposition agents and other additives depending on the purpose can be appropriately added to the cleaning composition of the present invention.

The spray-type outdoor cleaning agent of the present invention is simple to use, has sufficient cleaning power, and can act on dirt without causing bubbles to drip even on a vertical surface and can be cleaned efficiently.

The present invention will be specifically described below with reference to examples. However, the present invention is not limited to these examples.

Examples 1-2 and Comparative Examples 1-6
A cleaning liquid having the composition shown in Table 1 was prepared and filled in a foam spray container. Using these examples and comparative products, (1) detergency and (2) foam adhesion were evaluated. The evaluation method is as follows.

(1) Detergency: The sample was evaluated for cleaning on the wall with moss and mold stains on the outside. For cleaning evaluation, an appropriate amount of sample was sprayed on the soil and left for 10 to 15 minutes. Thereafter, the wall surface was washed with water while gently rubbing with a brush, and then the soil removability was visually determined according to the following criteria.
○ ... Dirt is almost removed △ ... Dirt remains partially × ... Dirt is hardly removed

(2) Foam adhesion: The sample was sprayed once toward the center of a 20 cm square acrylic plate leaning vertically. The adhesion rate was calculated from the weight of bubbles remaining on the acrylic plate after 10 seconds using the following formula.

As can be seen from Table 1, the liquid detergent samples of the examples showed good results in all items.
