Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hard surface cleaning composition for cleaning hard surfaces such as tableware, cooking utensils, sinks, bathrooms, toilet bowls, floors, walls and metal surfaces. The present invention relates to a hard surface cleaning composition which has excellent surface cleaning properties and foaming properties, as well as excellent feeling in use and less rough hands.

[0002]

2. Description of the Related Art Generally, a hard surface cleaning agent used for cleaning hard surfaces such as tableware usually has a main purpose of removing greasy stains, and a user is a cleaning agent. In most cases, oil and grease stains are removed by whipping with a hand or sponge during use. The function of the foam at this time is to relieve the force required to scrape off the dirt, and in many cases, the amount of foaming is often a measure of the cleaning property of grease stains. Therefore, in such a detergent, its high foaming power is an important factor, and conventional hard surface detergents have alkylbenzene sulfonate, α-olefin sulfonate, alkyl sulfate, alkane sulfonate as a main surfactant, Anionic surfactants such as ethoxylated alkyl ether sulphates have been used. Among them, sodium alkylbenzene sulfonate has been widely used as a base having excellent cleaning performance, but it has a drawback that it has a strong degreasing power from the skin and is likely to cause rough hands.

In order to prevent this drawback, conventionally, an anionic surfactant has been used as a main cleaning base, and a nitrogen-containing, amphoteric or nonionic, such as a tertiary amine oxide, higher fatty acid alkanolamide or alkyl betaine, has been used. What was used in combination with a sex action surface active agent was used.

However, although the action of the anionic surfactant, which is the main base, on the skin of such a detergent composition has been moderated to some extent, it has not yet reached a satisfactory level. This is a problem because the sebum component of the skin is removed and the hand feels worse after use, such as a tighter skin. In addition, it also had the drawback of poor rinsing properties.

[0005]

Therefore, a hard surface cleaning composition which is excellent in detergency and foaming power, has good rinsability, does not cause rough hands, and has a good feeling of hand skin after washing is desired. Was there.

[0006]

Under such circumstances, the inventors of the present invention have conducted diligent research to improve the above-mentioned problems, and as a result, have found that detergent compositions containing a surfactant have different carbon numbers. If two kinds of glycerin fatty acid ester having a fatty acid residue are blended in a certain ratio in a certain amount, the detergency and foaming ability are excellent, the rinsing property is good, and the feeling after washing is good without hand roughening. The present invention has been completed by finding that a hard surface cleaning agent can be obtained.

That is, the present invention provides the following components (a)-
(C): (a) Surfactant 1 to 40% by weight, (b) Glycerin fatty acid ester 1 to 20 in which fatty acid residue has 16 to 24 carbon atoms and monoglyceride content is 75 to 100% % Of glycerin fatty acid ester (c) in which the fatty acid residue has 8 to 14 carbon atoms and the monoglyceride content is 75 to 100%, and (a) + (c ) Is 5 to 40% by weight,
(B) / [(a) + (c)] is a weight ratio of 0.05 to 1, and (b) / (c) is a weight ratio of 0.1 to 10 It is provided.

The component (a) surfactant used in the present invention is not particularly limited, but anionic surfactants are preferable, and among them, the following are preferable.

It is preferable to add 1% by weight or more to the product. On the other hand,
If the total amount exceeds 20% by weight, the solution stability is significantly deteriorated.
Therefore, it is not preferable. Particularly preferred compounding amount is 1 to 10
The amount is%. Further, the weight ratio with the component (a) (d) / (a)
Is 0.1 to 0.3 for the above effect expression.
Is preferred.

Since the glycerin fatty acid ester as the component (b) is also one of the sebum components, it can be incorporated into the composition of the present invention at a specific ratio so that it remains on the skin after use and is moisturized. It gives a feeling and also has the function of protecting the skin of the hands. Therefore, in order for this component to remain on the skin, it can be said that a highly hydrophobic one is preferable. However, use of a material having a high content of triglyceride and diglyceride and high hydrophobicity deteriorates the solution stability of the composition, impairs the detergency and foaming power, and further enhances the oily feeling and the usability. Therefore, the glycerin fatty acid ester has an appropriately balanced hydrophobicity and hydrophilicity, that is, the fatty acid residue has 16 to 24 carbon atoms, particularly 16 to 22 carbon atoms, and the monoglyceride content is 75.
It is preferably about 100% by weight. The component (b) is contained in the detergent composition in an amount of 1 to 20% by weight, preferably 3 to 15% by weight. If this amount is less than 1% by weight, the above-mentioned effect is small, and if it exceeds 20% by weight, an oily feeling is strengthened, which is not preferable.

In the present invention, the glycerin fatty acid ester as the component (c) has a remarkable foaming effect when used in combination with the component (a), and further has a function of improving rinsability when used in combination with the component (b). In order to sufficiently exert this foaming effect, it is preferable to use a glycerin fatty acid ester having a relatively high HLB value and good compatibility with the component (a). Therefore, it is preferable that the fatty acid residue of the glycerin fatty acid ester has 8 to 14 carbon atoms, particularly 10 to 12 carbon atoms, and the monoglyceride content is 75 to 100%.

The component (c) is contained in the detergent composition in an amount of 1 to 10
It is contained by weight%. If this amount is less than 1% by weight, the foam-increasing effect is small, and if it exceeds 10% by weight, the detergent composition remarkably thickens and is difficult to take out from the container, which is not preferable.

In order to enhance the persistence of the component (b) on the skin in the cleansing composition of the present invention and not to impair the cleansing power and foaming power which are the basic performances as a cleansing agent, the above-mentioned 3
It is necessary to adjust the compounding ratio of the components. That is,
It is necessary that the content of the components (a) and (c) is 5 to 40% by weight, and if the content is less than 5% by weight,
The detergency and foaming power are not sufficient, and when it exceeds 40% by weight, the solution stability is significantly impaired, and thus both are not preferable. A particularly preferred content is 10 to 30% by weight.

The components (a) to (c) are (b) /
It is necessary that [(a) + (c)] = 0.05 to 1 (weight ratio), and if it is less than 0.05, the persistence of the component (b) on the skin is reduced and 1 When it exceeds, the detergency and the foaming ability are impaired, which is not preferable.

Further, when the component (b) and the component (c) are used together in a fixed weight ratio, the rinsability is greatly improved during cleaning, while having abundant foaming. In order to achieve such effects, it is necessary that (b) / (c) = 0.1 to 10. If the ratio is out of this range, the effect of improving rinsability cannot be obtained.

In addition to the above-mentioned components, the cleaning composition of the present invention may contain various components, if necessary, within a range that does not impair the intended performance. Examples of the surfactant include nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, and fatty acid alkanolamide, and amphoteric surfactants such as alkyl betaine and alkyl sulfobetaine. Examples of the solubilizer used in the liquid detergent include lower alcohols such as ethanol and isopropanol, polyhydric alcohols such as ethylene glycol, propylene glycol, glycerin and sorbitol, p-toluene sulfonate and m-xylene sulfonate. And aromatic sulfonates. In addition, flavors, pigments, antiseptic / antifungal agents, thickeners and the like can be added as desired.
