[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a novel liquid detergent composition, and more specifically, as a bath or shower soap, it has particularly good foaming properties, does not make the skin squeaky, leaves a smooth finish, and leaves the skin silky and silky. To provide a liquid detergent composition for the body or hair, which leaves a feeling of touch, does not make the hair squeaky as a hair shampoo, gives a silky finish, and does not disturb the hair. Conventional technology and its problems When commonly used anionic surfactants are repeatedly used in body cleansing products such as bath and shower soaps, the skin becomes dry and slimy after use due to its strong degreasing ability. There is a feeling. Furthermore, when an anionic surfactant is used as a shampoo for hair, the foaming properties are unsatisfactory and the degreasing power is strong, so the hair becomes dry and untidy after use. Moreover, when an alpha olefin sulfonate with a low fat content is blended, the solubility at low temperatures becomes poor and small crystalline particles are formed, impairing commercial value. The present inventors have completed the present invention as a result of extensive research in order to eliminate all of these drawbacks. Means for Solving the Problems The present invention is a liquid cleaning composition comprising the following components (A) to (G). A liquid cleaning composition consisting of the following components (A) to (G); (A) polyoxyethylene sulfosuccinic acid alkyl ester represented by the general formula () (In the formula, R ₁ is an alkyl group or alkenyl group having 8 to 21 carbon atoms, n is an integer of 1 to 15, and X is an alkali metal.) 0.5 to 5% by weight, (B) in the general formula () Fatty acid amidoalkyldimethylaminoacetic acid betaine shown (In the formula, R ₂ means an alkyl group or an alkenyl group having 9 to 17 carbon atoms, and R ₃ means an alkylene group having 1 to 6 carbon atoms, respectively.) 0.5 to 5% by weight, (C) A group having 10 to 18 carbon atoms α-olefin sulfonate 1-20% by weight, (D) C12-20 fatty acid salt 1-10% by weight, (E) Metal salt 1-10% by weight, (F) Optional additives 0-5 (G) Water 45-96% by weight. Regarding component (A), in the ester compound represented by the general formula (), the alkyl group represented by R ₁ includes a capryl group, a lauryl group, a coconut oil fatty group, a beef tallow fatty group, a rimistyl group, a behenyl group, an isolauryl group. , isomyristyl group, isopalmityl group, isostearyl group, isobhenyl group, etc., and examples of the alkenyl group include oleyl group, linoleyl group, etc. The alkali metal represented by X is preferably sodium or potassium. Regarding the content of component (A), this is 0.5% by weight.
If it is below, foaming will be poor and the stability of the composition will be poor. On the other hand, if component (A) is added in an amount of 5% by weight or more, the composition will feel sticky and the stability of the composition will deteriorate. Therefore, the content of component (A) is 0.5 to 5% by weight.
limited to. The preferred content is 1-3% by weight, and the most preferred content is about 2.25% by weight. Next, regarding component (B), in the betaine compound represented by the general formula (), the group represented by R ₂ CO- is capric acid, lauric acid, coconut oil fatty acid, tallow fatty acid, myristic acid, palmitic acid,
It is a residue of an acid such as stearic acid, behenic acid, isolauric acid, isomyristyrenic acid, isostearic acid, oleic acid, or linoleic acid. The alkylene group represented by R ₃ includes a methylene group, an ethylene group, a propylene group, a butylene group,
Examples include isopropylene group and isobutylene group. Regarding the content of component (B), this is 0.5% by weight.
If the amount is less, the lather will be poor, the soap will not wash cleanly as a bath or shower soap, the skin will be dry, and the hair shampoo will not make the hair supple and dry. Moreover, the stability of the composition is also poor. On the other hand, if this content exceeds 5% by weight, betaine, the component (B), is an amphoteric surfactant, so it becomes sticky to the skin, making it undesirable as a shower soap without a bath or as a hair shampoo. , the stability of the composition is also poor. Therefore, the content of component (B) is 0.5 to 5
% by weight. The preferred content is 1-3% by weight, and the most preferred content is 2.25% by weight. Next, regarding component (C), α-olefin sulfonate is mainly α-olefin monosulfonate having 10 to 18 carbon atoms, and contains small amounts of α-olefin disulfonate and hydroxyalkane monosulfonate. Sometimes. If the content of component (C) is 1% by weight or less, there will be no detergency and the product will not function as a bath or shower soap or hair shampoo. On the other hand, if it contains component (C) at 20% by weight or more,
The stability of the composition deteriorates and the foaming power is lost.
Therefore, the content of component (C) is limited to 1 to 20% by weight. The preferred content is 5 to 15% by weight,
The most preferred content is 9.75% by weight. Next, regarding component (D), the fatty acid salts include lauric acid, myristic acid, palmitic acid, stearic acid, isomyristic acid, isopalmitic acid,
Examples include alkali metal salts of fatty acids such as isostearic acid, oleic acid, and linoleic acid, and salts of the above fatty acids with amines such as triethanolamine and diethanolamine. If the content of component (D) is less than 1% by weight, the soap will not foam well and will not function as a bath or shower soap or hair shampoo. On the other hand, if component (D) is contained in an amount of 10% by weight or more, the stability of the composition will be poor and foaming will be poor, so the content of component (D) is limited to 1 to 10% by weight. The preferred content is 3-8% by weight, and the most preferred content is 5.25% by weight. Examples of the metal salt (E) include hydrochloric acid or sulfate of alkali metals or alkaline earth metals such as sodium chloride, potassium chloride, magnesium chloride, calcium chloride, sodium sulfate, potassium sulfate, and magnesium sulfate. Regarding the content of metal salt (E), this is 1% by weight.
However, the stability of the composition is poor, and the usability as a bath or shower soap or hair shampoo is poor. On the other hand, if this content exceeds 10% by weight, the composition becomes gel-like, resulting in poor stability and poor foaming power. Therefore, the ingredients
The content of (E) is limited to 1 to 10% by weight. The preferred content is 2-7% by weight, and the most preferred content is 3.25% by weight. Finally, as optional additives (F), general-purpose cosmetic raw materials such as preservatives, perfumes, humectants, or nonionic activators as cleaning aids are optionally used in combination in usual amounts. Its content is 0-5% by weight. Effects Since the composition according to the present invention contains polyoxyethylene sulfosuccinic acid alkyl ester (A), it has good performance as a bath or shower soap or hair shampoo, has excellent foaming power, and has no excess It has no fat-increasing power and provides mild cleaning properties. The composition according to the invention also comprises the amphoteric surfactant fatty acid amide alkyldimethylaminoacetic acid betaine (B) and a metal salt such as magnesium chloride.
Contains (E), so these react and the pH ranges from PH5 to PH8.
In between, the foaming power increases and foaming becomes better, and moderate moisture is obtained to maintain hair's moisturizing properties. Furthermore, since the composition according to the present invention contains α-olefin sulfonate (C), it has good detergency. In addition, the inclusion of the metal salt (E) such as magnesium chloride eliminates the precipitation of microcrystals of the salt (C), so when this composition is used in bath or shower soaps, the salt (E) remains slimy forever. The disadvantage of C) is overcome. Furthermore, when this composition is used as a hair shampoo, the hair will not feel squeaky and will have a mild texture. Furthermore, since the composition according to the present invention contains a fatty acid salt (D), when used as a shower soap without a bath, conventional soaps will foam and remain slimy for a long time when you rub your hands together. , such a phenomenon is eliminated and the result is a smooth wash. Effects of the Invention The liquid cleaning composition according to the present invention has a milky milky appearance, is extremely stable even when stored for a long period of time, maintains a moderately good viscosity, and when used as a bath or shower soap. It lathers well, and you can expect it to lather well with a regular towel without using a sponge towel. And after use, it leaves a clean and smooth wash without any dry feeling. It also lathers well as a hair shampoo.
It does not make the hair squeaky, has a moisturizing effect, and makes the hair manageable. Examples Next, examples of the present invention will be described.
