[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to a cleaning composition that leaves the skin of the hands feeling moisturized and moisturized.

[0002]

[Prior Art] Since cleaning agents such as kitchen detergents, household detergents, shampoos, body shampoos, and laundry detergents inevitably come into contact with the skin of hands and other surfaces during cleaning, they have conventionally been applied with mild, A cleaning agent composition that does not give a sticky feeling has been studied.

[0003] Fatty acids with 6 to 18 carbon atoms and 5 to 6 carbon atoms
A sugar ester surfactant consisting of an ester of a monosaccharide with a monoalkyl ether is known as a mild surfactant that causes little skin irritation. However, detergents containing sugar ester surfactants do not necessarily leave the skin feeling moisturized after use, and the skin loses its moisture, resulting in irritation and dryness. There were times when I felt "Satsuki".

[0004]

OBJECTS OF THE INVENTION The present invention provides a cleaning composition that makes the skin of the hands feel moisturized 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 lower alkyl ethers thereof, which have substantially no surfactant ability: 0.001 to 10% by weight.

[0006] The sugar ester surfactant, which is the component (a) of the present invention, is a surfactant that has little skin irritation and is _mild to the skin _. It is obtained from fatty acid derivatives 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 fatty acid residues preferably have 8 to 12 carbon atoms.

[0008] In addition, as fatty acid derivatives, fatty acid esters of the above-mentioned fatty acids and lower alcohols are used, and examples thereof include methyl esters, ethyl esters, propyl esters, etc. of the above-mentioned fatty acids. Preferably, the number of carbon atoms in the fatty acid residues is is 8-12
belongs to.

[0009] 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.

[0010] The sugar ester surfactant as the component (a) of the present invention may be mainly composed of a monoester type in which a C ₆ to _{C 18} fatty acid residue is ester-bonded to one hydrogen group of a monosaccharide. Preferably, the amount of polyester of triester or higher is 1% by weight or less.

[0011] (a) Component sugar ester surfactant is
1 to 50% by weight, preferably 5 to 50% by weight in the cleaning composition
Contains 30% by weight. 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.

[0012] Monosaccharides in component (b) monosaccharides or oligosaccharides and their lower alkyl ethers include xylose, arabinose, ribulose,
Monopentoses such as xylulose and lyxose;
Examples include monohexoses such as glucose, mannose, galactose, and fructose.

[0013] In addition, as oligosaccharides, carbon numbers 5 to 6
An oligosaccharide in which 2 to 6 monosaccharide units 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,
Examples include maltotriose, maltotetraose, maltopentaose, and the like.

[0014] Further, examples of the lower alkyl ethers include mono-, di-, and tri-lower alkyl ethers, and mono-lower alkyl ethers are preferred. Specific examples of these lower alkyl ethers include mono-lower alkylated monopentoses (mono-lower alkyl ethers) such as methyl xylose and ethyl arabinose, and mono-lower alkylated monohexoses (mono-lower alkyl ethers) such as methyl glucose and ethyl glucose. ); methyl maltose, ethyl lactose,
Examples include lower alkyl ethers of oligosaccharides such as methyltrehalose, and these lower alkyl ethers have substantially no surface-active ability.

[0015] Component (b) monosaccharides or oligosaccharides and their lower alkyl ethers are blended in the detergent composition in an amount of 0.001 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 moisturized and feels "moisturized". On the other hand, when component (b) is blended in an amount exceeding 10% by weight, the stability of the cleaning composition against microbial contamination deteriorates.

[0016] The cleaning composition of the present invention may contain various optional ingredients depending on its use, such as surfactants such as anionic surfactants, nonionic surfactants, cationic surfactants, and amphoteric surfactants. Alternatively, other additives may be appropriately blended.

[0017] Examples of anionic surfactants include the following. 1 Alkyl sulfate of C ₁₀ to C ₁₈ 2 Alkanesulfonate of C ₁₀ to _{C 18} 3 Olefin sulfonate of C ₁₀ to _{C 18}

[0018] 4 Alkylbenzene sulfonate with an alkyl group having a carbon number of C ₁₀ to C ₁₈ 5 an alkyl group or an alkenyl group with a carbon number of 10 to 18
polyoxyethylene alkyl (or alkenyl) ether sulfate (average number of added moles of ethylene oxide = 2 to 7)

[0019] Sulfonic acid salts of lower alkyl esters of 6 fatty acids (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, alkanols Amine salts and the like are used.

[0020] In addition, polyoxyethylene alkyl ether, polyoxyethylene/polyoxypropylene alkyl ether, alkylamine oxide, alkanolamine, fatty acid alkanolamide; lower alcohol, polyhydric alcohol,
Hydrotropes such as lower arylsulfonates; inorganic builders such as zeolites; sequestering agents such as ethylenediaminetetraacetate and diethylenetriaminepentaacetate; alkali builders such as carbonates and silicates; antibacterial agents such as benzoic acid. , enzymes, dyes, fragrances, etc. can be added.

[0021] The cleaning composition of the present invention can be applied as a cleaning agent for various purposes, but in particular, when it is used, the cleaning composition comes into contact with the skin such as the hands, skin, and scalp, and when it is used for cleaning dishes, tiles, etc. Suitable for cleaning hard surfaces such as glass, for example shampoo, body shampoo, kitchen detergent, bath detergent, etc.
Suitable for household detergents for toilets, laundry detergents, etc.

[0022]

Effects of the Invention According to the cleaning composition of the present invention, (a) a sugar ester surfactant consisting of an ester of a fatty acid and a monoalkyl ether of a monosaccharide;
(b) By using saccharides or their lower alkyl ethers, the moisture in the skin is retained even after washing, making the hands feel moisturized and preventing "squeakiness" and "crackiness" due to dryness. .

[0023]

[Example] Liquid detergents having the compositions shown in Tables 1 to 3 below were prepared and the "moisturizing" feeling on hand skin was evaluated, and the results are shown in Tables 1 to 3. Note that in the sugar ester surfactants in the table, expressions such as "C ₈ methylglucose ester" mean "ester of fatty acid having 8 carbon atoms and methylglucose", etc.

[0024] Method for evaluating the "moisturizing" feeling of hand skin After soaking the hand in a 10% by weight aqueous solution of the composition for 5 minutes,
The "moisture" feeling when hands were rinsed with running water and dried with a towel was sensory evaluated based on the following criteria. The rating was the average value of five panelists. Here, the "moisturized" feeling means that the skin retains moisture and does not feel "squeaky" or "difficult" due to dryness.
