Washable cleansing composition of fluid type with low-viscosity

The present invention relates to a low-viscosity emulsion type cleansing composition, and more specifically, is easier to form bubbles than the existing creamy face cleanser, is easily released in water, soft even as a small amount of fluid, and a fine foam rises abundantly. A user with sensitive or dry skin can remove skin impurities without irritation, and can maintain a soft and moist skin condition after use.

Generally speaking, a face wash includes a tissue-off type oil-based cleanser and a wash-off type water-based cleanser, which are general cosmetics used for cleanliness of the skin. The face wash removes various wastes such as sweat, sebum, dust, and aged keratin, make-up residues and other contaminants on the surface of the skin to keep the skin moist and healthy, resulting in good makeup. If the impurities remain on the skin, capillaries contract and blood circulation is weakened, the pores become clogged, and the oxygen and nutrient supply necessary for metabolism is disturbed. Rash or blemishes appear, and lipid peroxide builds up, causing premature aging.

The conventional aqueous cleansing agent was mainly a cream-type alkaline aqueous cleansing agent mainly composed of fatty acid soap, and this cleansing agent is used for all skins and is one of the most used cleansing agents as it cleanses perfectly not only skin waste but also makeup. However, there is a fear that the stimulation and sebum due to the friction between the skin is excessively removed at the time of washing, the skin is easily pulled out and wrinkles are ruined.

In order to prevent excessive sebum removal, a technique using a nonionic surfactant such as polyethylene glycol dioleate and polyethylene glycol diisostearate which effectively removes makeup and is rinsed well in water is disclosed (US Pat. No. 5,462,691). . These nonionic surfactants also remove skin impurities and moisturize the skin after use. However, the nonionic surfactants used at this time may not be expected to have clean skin due to their weak detergency.

In addition, an aqueous cleansing agent containing amino acid-based surfactant as a main component and emphasizing weakly acidic hypoallergenicity, however, has a disadvantage of weak foaming ability and slippage after use.

Therefore, the technical problem to be achieved by the present invention is better fluidity compared to the creamy water-based cleansing composition of the prior art, it is easy to form the foam, convenient to use, the washing effect is improved, rich and fine foam formation, irritation by skin friction It is to provide an emulsion-type aqueous face wash composition that can give a moist and soft skin feeling after washing.

In order to achieve the above technical problem, the present invention is 10 to 40% by weight of higher fatty acid soap having 8 to 22 carbon atoms; 0.5-45 wt.% Amino acid-based anionic surfactant; Polyalcohol 5-30% by weight; 0.5-5% by weight of ethyl glycol monostearate; 0.5-3 weight percent polymer; And it provides a low viscosity emulsion-type aqueous cleanser composition containing a residual amount of water.

More preferably, the present invention, the higher fatty acid soap of the aqueous cleanser composition is 8-12 carbon atoms, 14-16 carbon atoms And 18-22 carbon atoms A high viscosity fatty acid soap is a high viscosity fatty acid soap mixed at a ratio of 0-20 parts by weight, 20-80 parts by weight and 10-40 parts by weight, respectively.

The inventors of the present invention have made a surprising invention that, while studying various aqueous cleansing composition, the aqueous cleansing composition may have various advantages as described above in the technical problem when the aqueous cleansing composition has the above-described components and contents.

The high-fat fatty acid soap used as the main cleaning agent in the present invention is a soap-type anionic interface made by mixing at least one of the higher fatty acids having 8 to 22 carbon atoms with an alkali neutralizing agent, that is, potassium hydroxide, sodium hydroxide, or a mixture thereof to neutralize it. Its active amount is 10-40% by weight, more preferably 20-35% by weight.

In addition, the higher fatty acid soap is a mixture of high fatty acid soap having 8-12 carbon atoms, 14-16 carbon atoms and 18-22 carbon atoms in the proportion of 0-20 parts by weight, 20-80 parts by weight and 10-40 parts by weight, respectively. It is more preferable to achieve the above object of the present invention.

The selection and combination ratio of the one or more higher fatty acids and the degree of neutralization by the alkali neutralizing agent can influence the stable low viscosity properties.

As a low viscosity to maintain a stable physical properties and remove the skin pulling can give a moisturizing effect to add a moist feeling.

 Aqueous cleansing composition of the present invention also exhibits excellent cleaning power and strong protection against the skin, and can change fine, rich and pleasant foams of high-quality fatty acid soaps, and with massage effect and softness due to foam at the time of cleansing It includes an amino acid anionic surfactant that can minimize skin irritation and keep the skin condition moisturized after use. Such amino acid anionic surfactants include potassium cocoyl glycinate (POTASSIUM COCOYL GLYCINATE), SODIUM COCOYL GLYCINATE, TEI-COCOYL GLYCINATE, DISODIUM COCOAMPHODIACETATE, DISODIUM COCOLYPOLYTEATE, Coco-glucoside sulfosuccinate (DISODIUM COCO-GLUCOSIDE SULFOSUCCINATE) It can be used, one selected from potassium cocoyl glycinate, sodium cocoyl glycinate, tie cocoyl glycinate and the like and disodium coco ampodidiacetate, disodium coco ampodipropionate, disodium coco- It is preferable to use together and use 1 type chosen from glucoside sulfosuccinate.

The content of such amino acid-based anionic surfactant is 0.5-45% by weight, more preferably 1-25% by weight. At this time, when less than 0.5% by weight, the fine bubble formation ability is lowered, and when it exceeds 45% by weight, it is not possible to maintain the overall soft emulsion-type aqueous face wash phase.

The aqueous cleanser composition of the present invention is also excellent in fluidity compared to the existing cream phase, and contains 0.5-3% by weight of a polymer for showing excellent usability and soft and moist feeling while maintaining such physical properties. Such polymers may be used at least one of poloxamer 184, poloxamer 407, HYDROXYETHYL CELLULOSE, HYDROXYPROPYL METHYLCELLULOSE, and ACRYLATES COPOLYMER. have.

Experimental Example 2 Evaluation of Bubble Force and Bubble Holding Force

The initial foaming force and foam holding force of the said Example and the comparative example were evaluated. The initial bubble and bubble holding power were diluted with distilled-type aqueous cleanser composition in purified water to make a test sample (10g aqueous cleanser composition + 200g purified water), and then the sample was placed in a 1 liter measuring cylinder of a bubble tester, and a porous disk-shaped piston After the foam was formed by reciprocating 60 times at 60 rpm to measure the initial bubble formation volume by measuring the initial bubble formation volume, the bubble holding force was observed by measuring the bubble volume remaining after leaving it for 30 minutes.

The bubble retention rate, which can indicate bubble retention, was calculated by Equation 1 below, and the results are summarized in Table 3 below.

Bubble retention rate (%) = (bubble maintenance volume (ml) / initial bubble formation volume (ml)) × 100

Initial bubble formation volume (ml) Bubble holding volume (ml) Bubble retention rate (%) Example 1 950 870 91.6 Example 2 810 645 79.6 Comparative Example 1 760 545 71.7

50 women 20-30 years of age using the latex type aqueous cleansing composition were subject to the use of the latex type aqueous cleansing composition of Examples and Comparative Examples and evaluated the respective feelings. The feeling of use was evaluated by sensory satisfaction on bubble satisfaction and skin condition after use. The results are summarized in Table 4 below.

The sensory evaluation was performed based on the criteria of very good (5 points), excellent (4 points), normal (3 points), bad (2 points), and very bad (1 point), and the rating was expressed in Equation 2 below. Calculated accordingly.

Rating = {(very good number) × 5 + (good number) × 3 + (normal number) × 0 + (bad number) × (-3) + (very bad number) × (-5)} / total number of ratings
