BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milky liquid hard surface cleaner composition for cleaning hard surfaces such as tableware, cookware, sinks, bathrooms, toilets, floors, walls and metal surfaces. The present invention relates to a milky liquid hard surface cleaner composition which not only has excellent cleaning properties and foaming properties on these hard surfaces, but also has an excellent feeling in use and has 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 the oil and dirt. 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 sulphate, 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 together with the characteristic surfactant 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 hand. Therefore, there has been a demand for a hard surface cleaning composition which is excellent in detergency and foaming power, does not cause rough hands, and has a good feel on the skin after washing.

[0005]

Under such circumstances, the present inventors have conducted diligent research to solve the above-mentioned problems, and as a result, anionic surfactants and specific nonionic surfactants were It has been found that if a certain amount of a specific glycerin fatty acid ester is blended, it is possible to obtain a hard surface detergent composition which is excellent in detergency and foaming power, does not cause rough hands, and has a good feeling of hand skin after washing. Completed the invention.

That is, the present invention comprises the following components (a)-
(C) (a) Anionic surfactant 1-40% by weight (b) Ethylene oxide addition type nonionic surfactant and / or fatty acid alkanolamide 1-20% by weight (c) Carbon number of fatty acid residue 16 to 24 and 1 to 20% by weight of glycerin fatty acid ester having a monoglyceride content of 75% by weight or more, (a) + (b) is 5 to 40% by weight, and (c) / [(A) + (b)] is a weight ratio of 0.05 to 1
The present invention provides a milky liquid hard surface cleaning composition.

(5) Alkane sulfonate having 10 to 18 carbon atoms. Examples of the salt include alkali metal salts, alkaline earth metal salts, ammonium salts, alkanolamine salts and the like.
These anionic surfactants can be used alone or in admixture of two or more. The component (a) is blended in the detergent composition of the present invention in an amount of 1 to 40% by weight, preferably 10 to 30% by weight. If the blending amount is less than 1% by weight, the detergency and foaming ability will be insufficient,
If it exceeds 5% by weight, the solution stability is significantly deteriorated, which is not preferable.

The component (b), an ethylene oxide addition type nonionic surfactant and a fatty acid alkanolamide, are
When used in combination with the anionic surfactant as the component (a), effects such as enhancement of foaming power and relaxation of action on the skin are exhibited. The following are exemplified as preferable ones from the viewpoint of this effect and economical efficiency. (1) Polyoxyethylene alkyl ether represented by the general formula (4)

On the other hand, if the blending amount exceeds 20% by weight, the solution stability is significantly deteriorated, which is not preferable. A particularly preferable blending amount is 1 to 10% by weight. Further, the weight ratio (b) / (a) with the component (a) is preferably 0.1 to 0.5 in order to achieve the above effects.

Since the glycerin fatty acid ester as the component (c) is one of the sebum components, it can be incorporated into the composition of the present invention in a specific ratio so that it remains on the skin after use and is moisturized. It has the function of giving a feeling and 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, when a highly-triglyceride or diglyceride content is used and the hydrophobicity is high, the solution stability of the composition is deteriorated, the detergency and foaming power are impaired, the oily feeling is further strengthened, and the usability is deteriorated. . 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 18 to 22 carbon atoms, and the monoglyceride content is 75.
It is preferably about 100% by weight. The component (c) is contained in the detergent composition in an amount of 1 to 20% by weight. If this amount is less than 1% by weight, the above effect is small, and if it exceeds 20% by weight, the solution stability is deteriorated and foaming is impaired, which is not preferable. A particularly preferred content is 3 to 15% by weight.

In order to enhance the persistence of the component (c) 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,
The total of the components (a) and (b) is 5 to 40% by weight. If the content is less than 5% by weight, the detergency and foaming power are insufficient, and if it exceeds 40% by weight, the solution stability is high. Is significantly impaired, which is not preferable. The particularly preferred content is 10 to 30% by weight. The components (a) to (c) still need to be (c) / [(a) + (b)] = 0.05 to 1 (weight ratio), preferably 0.1 to 0.
It is 5. When it is less than 0.05, the residual property of the component (c) on the skin is reduced, and when it exceeds 1, the detergency and foaming power are impaired, which is not preferable.

In addition to the above-mentioned essential components, the detergent 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 amphoteric surfactants such as alkyl betaine and alkyl sulfobetaine. Examples of the solubilizing agent 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-toluenesulfonate and m-xylenesulfonate. And aromatic sulfonates. Further, fragrances, pigments, antiseptic / antifungal agents, thickeners and the like can be added as desired.
