BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition that makes the skin of the hands feel moist and moisturized.

0002

[Prior Art] In detergents such as kitchen detergents, household detergents, shampoos, body shampoos, and laundry detergents,
Because it is unavoidable to touch the skin of hands etc. when washing,
For some time, efforts have been made to develop detergent compositions that are mild and do not leave a "slimy" feeling on the skin.

[0003] Sugar ester surfactants, which are composed of esters of fatty acids having 6 to 18 carbon atoms and monoalkyl ethers of monosaccharides having 5 to 6 carbon atoms, are known as mild surfactants with little skin irritation. ing. however,
Cleaning agents containing sugar ester surfactants do not necessarily leave the skin feeling moisturized after use, and the skin loses moisture, causing creaking and dryness. There were times when I felt that.

0004

SUMMARY OF THE INVENTION The present invention provides a cleaning composition that leaves the skin of the hands feeling moist and "moisturized" after washing.

[0005]

[Means for Solving the Problems] The cleaning composition of the present invention is characterized by containing the following components (a) and (b). (a) Sugar ester surfactant consisting of an ester of a fatty acid having 6 to 18 carbon atoms and a monoalkyl ether of a monosaccharide having 5 to 6 carbon atoms: 1 to 50% by weight. (b) Monosaccharides or oligosaccharides having 5 to 6 carbon atoms and their alkyl ethers: 0.001 to 10% by weight.

The sugar ester surfactant which is the component (a) of the present invention is a surfactant that is mild to the skin with little skin irritation, and is a C6 to C18 fatty acid or a fatty acid derivative such as an ester of this fatty acid. and monoalkyl ethers of monopentoses and monohexoses.

[0007] Here, the fatty acid may be saturated or unsaturated, and may be linear or branched. Specific examples of such fatty acids include, for example, caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, caproleic acid, lauroleic acid, myristoleic acid, palmitoleic acid, oleic acid, methyl Examples include undecanoic acid, and preferably fatty acid residues have 8 to 12 carbon atoms.

[0008] As fatty acid derivatives, fatty acid esters of the above-mentioned fatty acids and lower alcohols are used.
Examples include methyl ester, ethyl ester, propyl ester, etc. of the above-mentioned fatty acids, and preferably fatty acid residues have 8 to 12 carbon atoms.

Examples of monoalkyl ethers of monopentoses include monoalkyl ethers of monopentoses such as xylose, arabinose, ribulose, ribose, xylulose, and lyxose, such as methyl and ethyl. Examples of monoalkyl ethers of monohexoses include monoalkyl ethers of monohexoses such as glucose, mannose, galactose, and fructose, such as methyl and ethyl.

The sugar ester surfactant as component (a) of the present invention is preferably a monoester type in which a C6 to C18 fatty acid residue is ester-bonded to one hydroxyl group of a monosaccharide; Polyester of ester or higher is 1
It is desirable that it is less than % by weight.

[0011] The sugar ester surfactant as component (a) is
1 to 50% by weight, preferably 5 to 30% by weight in the cleaning composition
% by weight is added. If this amount is too small, the cleaning effect and the "slimy" improvement effect will not be sufficiently achieved. On the other hand, even if the blending amount is increased, no improvement in cleaning performance is observed, and the stability of the system also deteriorates.

Monosaccharides or oligosaccharides and their alkyl ethers as component (b) include monopentoses such as xylose, arabinose, ribulose, xylulose, and lyxose; monohexoses such as glucose, mannose, galactose, and fructose; can be mentioned.

[0013] As the oligosaccharide, an oligosaccharide in which 2 to 6 monosaccharide units having 5 to 6 carbon atoms are bonded is used, preferably an oligosaccharide in which 2 to 4 monosaccharide units are bonded. Specific examples of these oligosaccharides include sucrose, maltose, lactose, trehalose, cellobiose, isomaltose, gentiobiose, gentianose, raffinose, stachyose, maltotriose, maltotetraose, maltopentaose, and the like.

Further, examples of the alkyl ethers include mono-, di-, and trialkyl ethers, but mono-alkyl ethers are preferred. Specific examples of these alkyl ethers include methyl xylose,
Monoalkylated products (monoalkyl ethers) of monopentoses such as ethyl arabinose; monoalkylated products (monoalkyl ethers) of monohexoses such as methyl glucose and ethyl glucose; alkyl ethers of oligosaccharides such as methyl maltose, ethyl lactose, and methyl trehalose. is exemplified.

Component (b) monosaccharides or oligosaccharides and their alkyl ethers are present in the detergent composition in an amount of 0.00
It is blended in an amount of 1 to 10% by weight, preferably 0.1 to 8% by weight. By adding 0.001% by weight or more of component (b), the skin of the hands after washing becomes moist and feels "moisturized". On the other hand, if more than 10% by weight of component (b) is added,
The stability of the cleaning composition against microbial contamination is degraded.

The cleaning composition of the present invention may contain various optional ingredients depending on its use, such as anionic surfactants,
Surfactants such as nonionic surfactants, cationic surfactants, amphoteric surfactants, and other additives may be appropriately blended.

Examples of anionic surfactants include the following. 1) C10-C18 alkyl sulfate 2) C1
0-C18 alkanesulfonate 3) C10-C
18 olefin sulfonates

4) Alkylbenzene sulfonate whose alkyl group has carbon atoms of C10 to C18 5) Alkyl group or alkenyl group has carbon atoms of 10 to C18
18 polyoxyethylene alkyl (or alkenyl) ether sulfate (average number of added moles of ethylene oxide = 2 to 7)

6) Sulfonic acid salts of fatty acid lower alkyl esters (fatty acid has 10 to 20 carbon atoms, alkyl group has 1 to 3 carbon atoms) These salts include alkali metal salts, alkaline earth metal salts, ammonium salts, Alkanolamine salts and the like are used.

In addition, hydrotropes such as polyoxyethylene alkyl ether, polyoxyethylene/polyoxypropylene alkyl ether, alkylamine oxide, alkanolamine, fatty acid alkanolamide; lower alcohol, polyhydric alcohol, lower aryl sulfonate, etc. Agents: Inorganic builders such as zeolite, sequestering agents such as ethylenediaminetetraacetate and diethylenetriaminepentaacetate; Alkali builders such as carbonates and silicates; Antibacterial agents such as benzoic acid, enzymes, pigments, fragrances, etc. added. can do.

[0021] The cleaning composition of the present invention can be used as a cleaning agent for various purposes, but in particular, it can be used in applications where the cleaning composition comes into contact with the skin of the hands, skin, scalp, etc., tableware, tiles, etc. It is suitable for cleaning hard surfaces such as glass, and is suitable for use, for example, in shampoos, body shampoos, kitchen detergents, household detergents for baths and toilets, and laundry detergents.

[0022]

[Effect of the invention] According to the cleaning composition of the present invention, (a
) By using together a sugar ester surfactant consisting of an ester of a fatty acid and a monoalkyl ether of a monosaccharide, and (b) a sugar or its monoalkyl ether,
Even after washing, the skin remains hydrated, making your hands feel moisturized, and preventing squeaks and dryness.

[0023]

[Example] Liquid detergents having the compositions shown in Tables 1 and 2 below were prepared and the "moisturizing" feeling on the skin of hands was evaluated. The results are shown in Tables 1 and 2. In addition, "C8 methyl glucose ester" in the sugar ester surfactant in the table
etc. means "ester of fatty acid having 8 carbon atoms and methyl glucose", etc.

[0024] Method for evaluating the “moisturizing” feeling of hand skin Composition 1
After soaking your hands in the 0% by weight aqueous solution for 5 minutes, rinse them with running water.
The "moisture" feeling when drying hands with a towel was sensory evaluated based on the following criteria. The rating was the average value of five panelists. Here, what is the “moisture” feeling?
This means that the skin retains moisture and does not feel "squeaky" or "healing" due to dryness.
