Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing composition in a transparent or translucent gel form,

The present invention relates to a gel-type cleansing cosmetic composition which does not flow down during application of a skin while maintaining the feeling of use, cleansing effect and transparent appearance of an existing washable cleansing cosmetic.

Cleansing Cosmetics for Clearing Cosmetics are classified into cream, oil, liquid, and transparent gels, and the types are classified into emulsion type, oil type, and aqueous type.

The emulsion type is exemplified by cleansing lotion and cream, which are known to have excellent cleansing effect on cosmetics and excellent softness and massage effect when used in an amount of 20 to 70% by weight based on the total weight of oily components. However, since such emulsion type uses a large amount of oil, the oil may remain on the skin after use and can not be completely rinsed off with water. Therefore, it is necessary to wipe off with a tissue off. This may cause skin irritation due to physical stimulation. And it is inconvenient to use water cleansing using foam cleansing or soap.

The aqueous-type cleansing gel can be divided into a microemulsion gel type using a large amount of nonionic surfactant and a large amount of oil, and a cleansing gel type using anionic surfactant. The surfactant is contained in an amount of 10 to 40% Is relatively high in weight%. Since the former contains a large amount of oil and surfactant, it has excellent cleansing power, but it has a feeling of use that is stiff and it is hard to wash it completely with water because oil remains on the skin after use. The latter uses anionic surfactant without oil, so it can be washed easily with water and is neat to use. However, the cleansing effect of removing makeup is poor, and skin irritation may be caused by 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 a problem, Japanese Patent Application Laid-Open No. 2003-136888 discloses a cleansing cosmetic filled in a pressure can discharge container using a volatile solvent.

Accordingly, the present inventor has intensively studied the increase of oil to develop gel-type washable cleansing oil cosmetics which can maintain the sensation of feeling and transparent appearance of the conventional cleansing oil described above and can be washed out with water, come. As a result, it is possible to use a dextrin fatty acid ester to initially maintain a transparent gel-phase with no fluidity, while its structure gradually melts at body temperature and friction during skin application, And the present invention was completed.

In order to achieve the above object, the cleansing cosmetic according to the present invention is characterized by containing a dextrin fatty acid ester as a thickening agent.

Hereinafter, the present invention will be described more specifically.

The present invention provides a cleansing cosmetic composition comprising a dextrin fatty acid ester which is an oil thickening agent, a surfactant, and an oil component.

More preferably, in the cosmetic composition according to the present invention, the composition comprises 0.5 to 30% by weight of a dextrin fatty acid ester based on the total weight of the composition; 5 to 30% by weight of a surfactant; And 50 to 94.5% by weight of the oil component.

The cosmetic composition according to the present invention is a transparent or semitransparent gel-like composition which does not flow down upon application of the skin.

Examples of the dextrin fatty acid ester according to the present invention include Dextrin behenate, Dextrin stearate, Dextrin palmitate, Dextrin palmitate / Ethyl hexanoate, Dextrin myristate, and the like. These may be used alone or in combination.

The cleansing cosmetic composition according to the present invention may further comprise dextrin palmitate, dextrin palmitate / ethylhexanoate or a mixture thereof, which is a thickening agent having a branched alkyl group in the dextrin fatty acid ester, .

The dextrin fatty acid ester can control the degree of oil increase in the range of 0.5 to 30% by weight based on the total weight of the cleansing oil cosmetic, due to the nature of the raw material. Preferably the dextrin fatty acid ester can be adjusted in the extent of the oil in the range of 0.5 to 20% by weight. If the content is less than 0.5% by weight, the viscosity is insufficient and the temperature stability is insufficient. If the content is more than 20% by weight, the hardness of the product may be excessively increased and the feeling of use may be lowered.

The cleansing cosmetic composition of the present invention preferably contains 5 to 30% by weight of a nonionic surfactant in order to provide a washable effect that can be washed with water. When the amount is less than 5% by weight, the washability is poor when washed with water. When the amount is more than 30% by weight, the viscosity increases and the spreadability is deteriorated to deteriorate the usability and the transparency is deteriorated and the appearance of the cleansing cream is absorbed. ≪ / RTI >

Surfactants use hydrophile-lipophile balance (HLB) values between 5 and 12. When HLB is less than 5, hydrophobicity is high, and when they are rinsed with water after use, they are less washable. When they are more than 12, hydrophilicity increases, And the phase becomes opaque according to the temperature change and the stability becomes poor. Therefore, it is important to properly combine a surfactant having a low HLB and a surfactant having a high HLB. As the surfactant used in the present invention, a polyethylene glycol surfactant, a polyglyceryl surfactant, a sucrose surfactant, or a mixture thereof may be used. A polyethylene glycol-based surfactant having 5 to 40 moles of ethylene oxide Examples of the surfactant include polyethylene glycol isostearate, polyethylene glycol diisostearate, polyethylene glycol glyceryl isostearate, polyethylene glycol glyceryl triisostearate, polyethylene glycol laurate, polyoxyethylene Ethylene sorbitan tetraoleate, polyoxyethylene triglyolate, polysorbate 85, polysorbate 60 and polysorbate 80 may be used alone or in combination, and examples of the polyglyceryl surfactant include polyglyceryl caprylate Polyglyceryl caprate, polyglyceryl < RTI ID = 0.0 > Polyglyceryl isostearate, polyglyceryl diisostearate, polyglyceryl dilaurate, polyglyceryl diolate or polyglyceryl diisostearate, polyglyceryl diisostearate, polyglyceryl diisostearate, Polyglyceryl di-myristate may be used alone or in combination. Examples of sucrose surfactants include sucrose laurate, sucrose myristate, sucrose palmitate, sucrose stearate, sucrose It is possible to use at least one surfactant selected from oystic acid, oystic acid, oystic acid, osteostearate, osteostearate, osteostearate, osteostearate, osteostearate,

In the emulsion type cosmetic composition according to the present invention, the kind of the oil is not particularly limited, and a common oil used in the cosmetic composition can be used. 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 One or more oils selected from the group consisting of

The composition of the present invention may further contain a humectant, an ultraviolet absorber, a perfume or the like in addition to the components described above, depending on the purpose. As the moisturizing agent, glycerin, 1,3-butylene glycol, dipropylene glycol, propylene glycol, sorbitol, or natural-derived extract, which are conventionally used in cosmetics, may be used.

The cleansing cosmetic composition according to the present invention is suitable for a degree of hardness not having fluidity that can be contained in a self-contained container, but is lower than that, so that it is possible to provide a constellation having a viscosity that can be contained in a pump. When applied to the skin, it does not flow like the existing cleansing oil, but it prevents the oil from flowing from the face to the neck during the application process.

In addition, since the cleansing cosmetic according to the present invention exhibits a transparent or translucent appearance, it is possible to give a specific property with high viscosity to the existing cleansing oil.

The cleansing cosmetic according to the present invention uses a dextrin fatty acid ester as an oil thickening agent to initially take out a transparent or semitransparent gel phase having no fluidity and to remove it from its container and to have fluidity when applying the skin, And can provide a feeling similar to that of conventional oil. Therefore, the cleansing cosmetic of the present invention can prevent the oil from flowing down to the floor during the process of releasing the oil for the first time, preventing the oil from flowing down to the face during the application process, and uniformly spreading on the face At the same time, the cleansing effect was the same or better.

Hereinafter, embodiments of the present invention will be described in detail to facilitate understanding of the present invention. However, the embodiments according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following embodiments. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art.

The present invention relates to a cleansing cosmetic composition comprising an oil thickener, a surfactant and an oil component. In order to find the conditions for exhibiting excellent stability and properties as a cosmetic, the present invention was evaluated in accordance with the following Experimental Example with different kinds and contents of the oil thickener.

oil Incrementer  Stability of Cleansing Oil by Type

Each oil thickener was heated to a temperature of 80 ° C or higher to completely dissolve it, and then left at room temperature for one day to sufficiently lower the temperature. Each was placed in a constant temperature bath at 25 ° C and 50 ° C, and the degree of oil separation was observed for a total of one month at intervals of one day. The same amount of mineral oil and octyldodecanol were used as the oil. Table 1 shows the results of evaluating the oil stability of each incremental agent in a 50 ° C thermostat.

Oil increment name usage Stability Dextrin palmitate / ethyl hexanoate
(Dextrin Palmitate / ethyl hexanoate) 5% Stable, transparent Dextrin myristate
(Dextrin Myristate) 5% Stable, translucent Dextrin palmitate
(Dextrin Palmitate) 5% Stable, opaque Dextrin palmitate / ethyl hexanoate
Dextrin palmitate 2.5%
2.5% Stable, translucent Trihydroxystearin 5% Oil leaks within 3 days, opaque Tribe henin
(Tribehenin) 5% Oil leaks within 3 days, opaque Cetearyl alcohol
(Cetearyl alcohol) 5% Separated within 3 days Quaternium-18 hectolite
(Quaternium-18 hectorite) 3% Oil leaks within 7 days, opaque Hydroxystearate
(Hydroxystearate) 3% Separated within 3 days, opaque

As can be seen from the above Table 1, at 50 DEG C, the oil gradually leached out depending on the kind of the oil thickener.

When stored at 25 ° C, grease other than dextrin fatty acid esters leached into the upper layer within 1 month (25 ° C measurement results are not shown). This is due to the solubility of the oil thickener and the oil, and the structural characteristics of both, and it is preferable to select the oil thickener in view of the stability of the formulation. This experiment showed that the dextrin fatty acid ester maintains the most stable phase.

dextrin Palmitate / Ethyl hexanoate  Increase of Cleansing Oil by Content

The extent of the cleansing oil according to the content of the oil thickener was measured using dextrin palmitate / ethyl hexanoate as an oil thickening agent and is shown in Table 2 below. The same amount of mineral oil and octyldodecanol were used as the oil.

Dextrin palmitate /
Ethyl hexanoate content Incremental (based on stop) Less than 4% by weight Transparent oil-phase formation with high fluidity 4 to 10 wt% Slight flow when tilted with slight fluidity Greater than 10% by weight Soft gel formation like jelly on transparent gel with no fluidity

As shown in Table 2, when dextrin palmitate / ethylhexanoate was used alone as an oil thickening agent, the content of the oil thickener was most preferably 4 to 10% by weight based on the total weight of the composition.

dextrin Palmitate  Increase of Cleansing Oil by Content

The extent of the cleansing oil according to the content of the oil thickener was measured using dextrin palmitate as an oil-increasing agent and is shown in Table 3 below. The same amount of mineral oil and octyldodecanol were used as the oil.

Dextrin palmitate content Incremental (based on stop) Less than 3% by weight Semi-transparent oily phase formation with high fluidity 3 to 7 wt% Slight flow when tilted with slight fluidity Greater than 7% by weight Hard gel formation such as wax with semi-transparent gel without any fluidity

As shown in Table 3, when dextrin palmitate was used alone as the oil thickening agent, the content of the oil thickener was most preferably 3 to 7% by weight based on the total weight of the composition.

As can be seen from Tables 2 and 3 above, the degree of increase varies slightly depending on the type and content of the oil thickener used. In general, when the content of the oil thickener is low, the viscosity of the gel is generally low.
