Description

[0001] The present invention relates to an oily type cleansing cosmetic composition having a rapid phase-transition property,

The present invention relates to an underwater-type cleansing cosmetic composition which is quick-forward and cleans with water. More specifically, the composition of the present invention does not flow when it is taken out of a container and has a viscosity. However, since the composition of the present invention can be easily transferred into an oily phase upon application of the skin, the makeup component can be quickly and effectively melted and then washed with water, Type washable cleansing cosmetic composition.

In general, cleansing cosmetics for erasing makeups are classified into cream, oil, liquid and transparent gels, and the types are classified into aqueous, oily, and emulsion types.

The cleansing gel of the aqueous type is an anionic surfactant without using oil for the purpose of cleansing, in which the content of the surfactant is 10 to 40% by weight based on the total weight of the cleansing gel. The anionic surfactant can be easily washed with water, The cleansing effect of removing makeup is reduced and skin irritation is a concern due to anionic surfactant.

Oil-based cleansing oil uses almost 100% oil, so it has excellent make-up cleansing effect and excellent washability. However, since the oil having a low viscosity is used, there is a problem that it is inconvenient to flow down during use and it is difficult to use with wet hands. In order to solve such problems, recently, a cleansing oil having water resistance has been developed, and a solid oil formulation is being developed. Depending on the type of oils and moisturizers, solid waxes such as polyethylene, beeswax, glyceryl esters such as glyceryl behenate / eicosadioate may be selected to produce a solid form use. However, the solid wax such as polyethylene makes a solid appearance to the cleansing oil, but the feeling of use is relatively heavy, and since it is used in a large quantity, it has a hard solid property and poor taste, and has a disadvantage that it is not washed well with water.

The emulsion type is a form of oil in water (O / W) emulsion, in which cleansing lotion and cream are typical. They dissolve the make-up with a lot of oil and massage effect by oil is high. However, a large amount of oil is used and a large amount of surfactant is used in order to stabilize the internal phase. In this case, it takes a little time until the former phase (internal phase oil exits into the trauma) After this makeup is melted, it can not be washed with water, so it needs to be wiped off with a tissue. This may cause skin irritation due to physical stimulation, and even after cleansing with a tissue, due to the remaining oily feeling, foam cleansing or soap may be used, It is inconvenient to do. Korean Patent Publication Nos. 2010-0043455 and 2011-0138176 have made it possible to speed up the process by using a polymer thickener and a small amount of a surfactant, but it has not overcome the disadvantage of wiping with a tissue.

Accordingly, the inventor of the present invention has studied to develop an underwater type cleansing cosmetic material which can be easily washed with a small force and washed with water with excellent makeup removing power. The object of the present invention is to minimize the use of a surfactant, which provides an emulsion type without fluidity at the beginning and a phase which can be easily transferred with a small force during application of the skin to provide a feeling of use similar to conventional cleansing oil and convenient washing with water To provide an underwater type washable cleansing cosmetic which stabilizes a large amount of oil.

To achieve the above object, the water-washable cleansing cosmetic according to the present invention is characterized in that the water- 0.01 to 0.5% by weight of a polymer thickener, 0.01 to 0.5% by weight of sodium diaramidoglutamate succinate, 1 to 30% by weight of a nonionic surfactant and 30 to 98% by weight of an oil component.

Hereinafter, the present invention will be described more specifically.

The present invention provides an underwater type cleansing cosmetic composition comprising a water-soluble polymer thickener, sodium diaramidoglutamate dry, a nonionic surfactant and an oil component.

More specifically, the cosmetic composition according to the present invention comprises 0.01 to 0.5% by weight of a water-soluble polymer builder based on the total weight, 0.01 to 0.5% by weight of sodium diarraamidoglutarumiacein, 1 to 30% by weight of a nonionic surfactant, 30 to 98% by weight of the composition.

The water-soluble polymer thickener according to the present invention is a water-soluble polymer thickener which is selected from the group consisting of a carboxyvinyl polymer, an acrylate / alkyl acrylate crosspolymer having 10 to 30 carbon atoms, carboxymethylcellulose, sodium polyacrylate, acrylate / acrylamide copolymer, polyacrylamide, Acryloyldimethyltaurate / vinylpolymer, hydroxyethyl methacrylate / sodium acryloyldimethyltaurate copolymer, sodium acrylate / sodium acryloyldimethyltaurate copolymer, sodium acrylate / acryloyldimethyl Acrylate / dimethylacrylamide crosspolymer, acrylate / beheneth-25 methacrylate copolymer, ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer, PGI-150 / decyl alcohol / ≪ RTI ID = 0.0 > C12-22 < / RTI > alkyl methacrylate copolymer, Acrylate / stearate-20 methacrylate copolymer, an acrylate / stearyl methacrylate copolymer, an acrylate / stearyl methacrylate copolymer, a sodium acrylate copolymer, an acrylate / Vpicopolymer, Acrylate / stearyl methacrylate copolymer, an acrylate / C10-30 alkyl methacrylate copolymer, an acrylamide / sodium acrylate copolymer, an acrylate copolymer, a potassium acrylate / C10-30 alkyl acrylate crosspolymer , Polyacrylate crosspolymer-6, ammonium polyacrylate, and the like can be used.

According to the invention The water-soluble polymer thickening agent may be included in an amount of 0.01 to 0.5% by weight based on the total weight of the cleansing cosmetic composition. Preferably 0.05 to 0.3% by weight, and more preferably 0.07 to 0.2% by weight. When the content is less than 0.01% by weight, the emulsion is unstable because the oil can not be stabilized. If the content is more than 0.5% by weight, the emulsion is too viscous to produce an emulsion.

The sodium diaramidoglutamate according to the present invention may be in the form of a sodium salt of polycondensation of N-lauroyl-L-Glutamic acid and L-lysine of N-lauroyl-L-glutamic acid and L- Can be used. The sodium diaramidoglutamate Pellicer ™ from Asahi Kasei Japan can be used, which is a gemini type compound that forms liquid crystals and vesicles to form the skin barrier of the horny layer of the skin and adsorbed on the hair to defend and restore hair damage. In addition, the emulsifying power is excellent even in a small amount of use, so that the oil gel can easily be produced by a method of making a D gel or a liquid crystal gel. The structural formula of sodium diaramidoglutarate is shown in the following formula (1).

The sodium diaramidoglutamate dry according to the present invention may be contained in an amount of 0.01 to 0.5% by weight based on the total weight of the cleansing cosmetics in order to control the degree of oil increase. Preferably 0.05 to 0.3% by weight, and more preferably 0.07 to 0.2% by weight. If the content is less than 0.01% by weight, formation of a gel is insufficient and temperature stability is insufficient. If the content is more than 0.5% by weight, the hardness of the product is excessively increased, which is difficult to manufacture.

As the nonionic surfactant according to the present invention, a polyethylene glycol surfactant, a polyglyceryl surfactant, a sucrose surfactant, or a mixture thereof may be used. More specifically, there may be mentioned polyethylene glycol isostearate, polyethylene glycol diisostearate, polyethylene glycol glyceryl isostearate, polyethylene glycol glyceryl triisostearate, polyethylene glycol laurate, poly Polyethylene glycol monomers having an ethylene oxide content of 5 to 40 moles, such as oxyethylene sorbitan tetra-oleate, polyoxyethylene triglyolate, polysorbate 85, polysorbate 60, polysorbate 80, Surfactants; Polyglyceryl palmitate, polyglyceryl caprylate, polyglyceryl caprate, polyglyceryl laurate, polyglyceryl myristate, polyglyceryl stearate, polyglyceryl oleate, polyglyceryl isostearate, polyglyceryl diisostearate A polyglyceryl surfactant such as polyglyceryldilaurate, polyglyceryl diolate, and polyglyceryldimarylate; And polylactic acid esters such as sucrose laurate, sucrose myristate, sucrose palmitate, sucrose stearate, sucrose distearate, sucrose distearate, polyglyceryl diolate, polyglyceryl di A sucrose surfactant such as a state formerly; And the like may be used.

The nonionic surfactant according to the present invention may be contained in an amount of 1 to 30% by weight in order to impart a washable effect to the cleansing cosmetic composition, which can be washed with water. Preferably 2 to 20% by weight, and more preferably 3 to 10% by weight. When the amount of the surfactant is less than 1% by weight, the washability is poor when washed with water. When the surfactant is used in an amount exceeding 30% by weight, viscosity increases and the spreadability is deteriorated, resulting in deterioration of usability and excessive skin sebum adsorption.

The nonionic surfactant according to the present invention may have a hydrophile-lipophile balance (HLB) of 5 to 12. When the HLB is less than 5, the hydrophobicity is high, and when it is rinsed with water after use, the washability is decreased. When the HLB is 12 or more, the hydrophilicity is increased and the usability with oil is deteriorated. Therefore, a surfactant having a low HLB and a surfactant having a high HLB can be appropriately used in combination.

The kind of the oil according to the present invention is not particularly limited, and conventional oils used in the cosmetic composition may be used. More specifically, hydrocarbon oils such as squalane, mineral oil, hydrogenated polydecene, hydrogenated polyisobutene, and C12-15 alkyl benzoate; Caprylic / capric triglyceride, neopentyl glycol dicaprate, 2-octyldodecyl myristate, isopropyl myristate, isopropyl palmitate, isocetyl ethyl hexanoate, pentaerythritol tetraethyl hexanoate, Ester oils such as butylene glycol dicaprylate / caprate, hexyl laurate, diisostearyl malate, cetyl 2-ethylhexanoate, octyldodecanol, and glyceryl triethylhexanoate; Vegetable oils such as olive oil, avocado oil, jojoba oil, macadamia oil, grapeseed oil, rice bran oil; Animal oils such as lanolin; And silicone oils such as dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, methyltrimethicone, diphenylsiloxyphenyltrimethicone, caprylylmethicone, phenyltrimethicone, cyclomethicone, dimethicone and the like Any one or more oils selected from the group consisting of

The oil according to the present invention may be contained in an amount of 30 to 98% by weight based on the total weight of the cleansing cosmetic. Preferably 40 to 80% by weight, and more preferably 50 to 70% by weight.

In the cosmetic composition of the present invention, a moisturizer, an ultraviolet absorber, a fragrance or the like may be further blended according to the purpose in addition to the above components. The moisturizing agent may be glycerin, sorbitol, butylene glycol, dipropylene glycol, propylene glycol, pentylene glycol, propanediol, 1,2-hexanediol, octanediol, or naturally derived extract, which are conventionally used in cosmetics.

The underwater type cleansing cosmetic material according to the present invention may be provided in a form having a viscosity that is low enough to be contained in a self-container or a tube, but lower than that to the extent that there is no flowability. It can prevent the oil from flowing from the face to the neck during the application process because it does not flow like cleansing oil when applying the skin, and it is possible to provide convenient use because it can wash with water unlike the conventional cleansing cream.

The underwater type cleansing cosmetic composition according to the present invention is not viscous prior to application to the skin, but is easily transferred to an oily phase having fluidity upon application of the skin. Therefore, unlike the cleansing oil, the cosmetic ingredient may flow down There is no.

In addition, the cosmetic composition according to the present invention provides a feeling of use like a cleansing oil upon application of the skin to uniformly apply it to the face, dissolves the makeup ingredient quickly and effectively, exhibits similar or better cleansing power, It is possible and convenient to use. In addition, the cosmetic composition according to the present invention contains at least a thickening agent and is excellent in emulsion stability compared to other cosmetic compositions.
