Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid cleaning composition with excellent foaming properties, and more specifically, when sprayed onto an object to be cleaned using a pump-type spray gun, the present invention forms fine bubbles that swell well and have little dripping. to fully demonstrate the cleaning power of the liquid detergent,
The present invention relates to a liquid cleaning composition capable of dealing with even heavy soiling.

Conventionally, various liquid cleaning compositions have been used depending on the purpose, but in general, when sprayed onto the object to be cleaned with a pump-type spray gun, it is difficult to form bubbles, and even when bubbles are formed, Since it is rough and easily erased, and also drips down quickly, its cleaning power is not fully demonstrated, especially when the object to be cleaned has heavy dirt.

The present invention was made in order to solve the above-mentioned problem, and when sprayed onto the object to be cleaned with a pump type spray gun, the dirt on the object to be cleaned is engulfed for a long time,
To provide a foaming liquid detergent composition capable of forming fine, well-heavy foam on an object to be cleaned, and with little dripping so that the cleaning power of the detergent composition is fully exhibited. The purpose is to

The liquid cleaning composition according to the present invention comprises an alkyl sulfate ester which is an alkali metal salt, ammonium salt or alkanolamine salt of a compound represented by the general formula fal (wherein R represents an alkyl group having 9 to 11 carbon atoms). 1 to 10% by weight of type anionic surfactant, or the above surfactant and (b) general formula (wherein R2 represents an alkyl group having 9 to 11 carbon atoms, and n
represents a number from 1 to 5. 1 to 10% by weight of a mixture of a compound represented by the formula (C) with an alkyl ether sulfate type anionic surfactant which is an alkali metal salt, ammonium salt or alkanolamine salt, and (C) general formula %) (However, m is a number from 1 to 3.

In the present invention, as the first component of the foaming agent, the above-mentioned alkyl sulfate salt type surfactant or a mixture of this and the alkyl engineered ester sulfate type surfactant described above is used.

As the amount of the alkyl sulfate salt increases, the foam becomes finer, while the alkyl ether sulfate salt improves the shape retention of the foam as the amount of the alkyl sulfate salt increases. In the present invention, even if only the alkyl sulfate salt is used as the first foaming agent component, a cleaning composition having the desired effect can be obtained.
It is preferable to use the alkyl sulfate salt and the alkyl ether sulfate salt together in order to form foams that are fine in size and have better shape retention.

In the present invention, the surfactant as the first component of these foaming agents may be an alkyl sulfate salt alone or a mixture of this and an alkyl ether sulfate salt. It is blended in a range of 1 to 10% by weight, preferably 2 to 6% by weight, based on the detergent composition.

The alkyl sulfate salt and the alkyl ether sulfate salt may be any of alkali metal salts such as sodium and potassium salts, ammonium salts, or alkanolamine salts (preferably trialkanolamine salts such as triethanolamine salts), In particular, sodium salts are preferably used. However, the number of carbon atoms in the alkyl group is 9 to
It is necessary that the number of carbon atoms is 11, and it is particularly preferable that the number of carbon atoms is 10. Conventionally, alkyl sulfate ester salts and alkyl ether sulfate ester salts in which the alkyl group has 12 carbon atoms have been frequently used as surfactants from the viewpoint of cleaning power. Since it has poor foaming properties when sprayed, it is not suitable for use as a foaming agent component in the present invention. Incidentally, an alkyl sulfate ester salt having an alkyl group having 12 carbon atoms and an alkyl group having 10 carbon atoms
In combination with an alkyl ether sulfate salt having an alkyl group, only coarse foam is formed when the cleaning composition is sprayed onto the object to be cleaned, and such foam quickly drips from the object to be cleaned. .

In addition, in the present invention, as the second foaming agent component, glycol monobutyl ether represented by the general formula (C1, ie, ethylene glycol monobutyl ether or diethylene glycol monobutyl ether, etc.) is used as the second foaming agent component, based on the detergent composition. It is blended in a range of % by weight.

Particularly preferred is diethylene glycol monobutyl ether.

As described above, the cleaning composition of the present invention contains a foaming agent consisting of the alkyl sulfate ester and glycol monobutyl ether, preferably an alkyl sulfate ester, an alkyl ether sulfate ester, and glycol monobutyl ether, and Foaming agents also have some detergency in themselves. However, in the present invention,
In order for the detergent composition to have stronger detergency, in particular, conventionally known anionic surfactants such as alkylbenzene sulfonates and/or α-olefin sulfonates are used as detergent components. It is preferably contained in a range of 4 to 8% by weight. Here, as the alkylbenzene sulfonate, straight-chain compounds are preferred because of their excellent biodegradability, but this does not preclude the use of branched-chain compounds. If necessary, a nonionic surfactant can be used instead of these anionic surfactants.

Furthermore, the cleaning composition of the present invention preferably contains an aliphatic alkanolamide.

This is because this surfactant is useful for appropriately adjusting the viscosity of the cleaning composition and for stabilizing foam. In addition, cleaning aid compositions containing anionic surfactants as a main component usually include a cleaning aid known as hilgu, which has been conventionally known in the cleaning composition of the present invention. It can contain any builder.

In the present invention, silicates such as sodium metasilicate are preferably used from the viewpoint of environmental protection; however,
Phosphates, carbonates, etc., which have been widely used in the past, may also be used as necessary. The proportion of these builders is suitably 1 to 5% by weight based on the detergent composition. In addition, in order to improve the cleaning power against heavy dirt and dirt caused by oils and fats, it may contain hydric soda. The amount of hydric soda blended is not particularly limited, but is usually 3% by weight or less based on the detergent composition. In addition, it goes without saying that appropriate amounts of fluorescent agents, colorants, fragrances, antioxidants, etc. may be contained as necessary.

The cleaning composition of the present invention is not particularly limited, but usually includes:
5 to 30% by weight, preferably 1% by weight of all components as mentioned above
It accounts for 0 to 25% by weight.

As described above, the foaming liquid cleaning composition of the present invention comprises an alkyl sulfate salt having an alkyl group having 9 to 11 carbon atoms and an alkyl ether sulfate salt having an alkyl group preferably having 9 to 11 carbon atoms. , and glycol monobutyether, the synergistic effect of these agents results in a uniquely high foaming property. Forms foam with a large rise and little dripping, thus enveloping the dirt on the object to be cleaned in the foam for a long time.In this way, the cleaning power of the cleaning agent is fully demonstrated, and it can remove heavy dirt. can also be dealt with well.

The present invention will be explained below with reference to Examples. In the following, % indicates weight %.

Example 1 n-dodecylbenzenesulfonic acid Sodium 6% 1: Type 2 coconut oil fatty acid diethanol Ruamide 1% Alkyl sulfate salts and alkaline Kill ether sulfate salt 3% diethylene glycol monobutyl Ether 6% Sodium metasilicate 3% Conditioner, fragrance, etc. amount water remainder A cleaning composition (100% in total) was prepared.

The amounts of alkyl sulfate (AS) and alkyl ether sulfate (AES) are shown in Table 1. Table 1 shows the viscosity (value at 25° C. measured by a B-type viscometer) and foam properties of each cleaning composition.

The method for using the cleaning composition and the evaluation method for foam properties are as follows.

A vinyl chloride resin board moistened with water is stood vertically, and the cleaning composition is applied to it using a pump-type spray gun manufactured by Canyon Co., Ltd. (780).
Foam was formed by spraying 3 strokes from a distance of 17 cm using Model 0, and its fineness, rise, and dripping speed were observed.

Foam fineness: The diameter of foam particles occupying more than half of the total volume of the foam was visually observed and evaluated on the following three scales.

More than Al drunkenness B: 3-511m C: 5 dragons or more rise of bubbles The volume of the bubbles produced was visually observed and evaluated on the following three scales.

A: 20cn? Above: B: 12 to 20 cJ C: Below 12 cJ Foam dripping time Evaluation was made in the following three grades based on the time required for the generated foam to drip down 20 cm on the vinyl chloride resin plate.

A: 21 seconds or more B: 16 to 20 seconds C: 15 seconds or more In a three-level evaluation, each cleaning composition was rated with A as 3 points, B as 2 points, and C as 1 point, with a score of 9. ◎, 8 points as ○, 7 points as △, and less than that as ×, and the overall evaluation is shown in Table 1.

It is understood that the cleaning composition according to the present invention has excellent foaming properties, and the foam produced is fine, has a large bulge, and is difficult to run down.

Example 2 Sodium n-dodecylbenzenesulfonate 6% 1:2 type coconut oil fatty acid diethanolamide 1% Alkyl sulfate ester salt 1% Alkyl ether sulfate ester salt 2% Glycol monoalkyl ether (Table 2) Sodium metasilicate
A cleaning composition (100% in total) consisting of 3% regulator, fragrance, etc., appropriate amount water, and the balance was prepared, and the foam properties were evaluated in the same manner as in Example 1.

The results are shown in Table 2. It is clear that when ethylene glycol monobutyl ether or diethylene glycol mobutyl ether is used as the glycol monoalkyl ether, foaming properties are particularly good.
