Description

TECHNICAL FIELD [0001] The present invention relates to a gel-type essence cosmetic composition having excellent moisture retention,

The present invention relates to a gel-type essence cosmetic composition having excellent moisture retention, and more particularly, to a gel-type essence cosmetic composition having a moisturizing property and a cosmetic composition containing a large amount of a moisturizer, a high alcohol, a nonionic surfactant and an oil, The present invention relates to a cosmetic composition which has excellent moisture retention and nutritional sensation and has excellent formulation stability, as compared with general gel-type moisture essence because a formulation is formed and a large amount of moisturizing agent is contained.

Conventional common essence cosmetics are semi-transparent gel type essence which is mainly used in summer and opaque general emulsion type essence which is used at other times, and these two formulations are most common. The general translucent gel type essence provides a translucent visual effect compared to the opaque general emulsification type essence, but it has a drawback in that the moisturizing power is somewhat lower and the nourishment feeling is less when used. In this translucent formulation, the water phase is mainly composed of raw materials such as purified water, moisturizing agent (less than 15%), natural gum such as xanthan gum or a water-soluble polymer of the carboxyvinyl polymer system, and natural gums or water- And enhances the stability of the formulation. Since solid non-ionic surfactants, hydrocarbon oils and ester oils have the effect of making the formulation opaque, translucent gel-type formulations mainly use non-ionic surfactants in liquid or paste form, silicone oils and silicone polymers . Therefore, compared to general opaque essence formulations using solid phase nonionic surfactants, hydrocarbon oils and ester oils, the moisture resistance is somewhat lowered when used. The degree of opacity of the formulation increases as the difference in refractive index between the water phase and the oil phase increases. Therefore, narrowing the refractive index difference between the water phase and the water phase is a requirement for making a translucent formulation.

Many studies have been made on cosmetic compositions having excellent moisture resistance. A cosmetic composition containing a raw material rather than a formulation technique may have a somewhat difference in moisture resistance depending on the content of the raw material, as a composition patent containing mainly a raw material having moisture resistance in a formulation (disclosed in Patent Application Publication No. 1020050081543, Publication No. 1020090056028, Publication No. 1020070008831) have.

The object of the present invention is to provide a simple cosmetic composition comprising the above-described conventional translucent gel type moisture essence and a moisturizing raw material, and an object of the present invention is to provide a cosmetic composition containing a large amount of a moisturizing agent, a high alcohol, It is an object of the present invention to provide an essence cosmetic composition which shows a shape of translucent gel type visually differentiated by an emulsifying technique while having an excellent moisturizing power and a rich nourishment feeling when used.

The gel-type essence cosmetic composition according to the present invention is a translucent gel-type formulation visually differentiated when a large amount of a moisturizer, a high-alcohol, a nonionic surfactant and an oil are appropriately mixed and emulsified, Containing a large amount of moisturizing agent compared to water essence, it has very good skin moisturizing effect, feels good feeling of nutrition, and excellent formulation stability.

The present invention relates to a composition comprising 35 to 50% by weight of a moisturizer;

0.3 to 2.5% by weight of higher alcohol;

0.1 to 0.5% by weight of a water-soluble polymer;

0.1 to 5.0% by weight of a nonionic surfactant;

And 1.0 to 10.0% by weight of an oil.

Hereinafter, the present invention will be described in more detail.

The problem to be solved in the present invention is to make an essence formulation which is excellent in moisture retention and feeling of use while maintaining a translucent gel-type formulation. Generally, as described above, the semi-transparent formulations become more transparent as the refractive index difference between the water and oil phase is minimized. In order to narrow the difference in refractive index between the water phase and the water phase, a large amount of moisturizing agent was used in the present invention. In addition, these moisturizers not only narrow the difference in refractive index between the water and oil phase, but also gellify when the higher alcohol, surfactant and oil are appropriately blended and emulsified, so that the transparency of the formulation can be further increased and the feeling of use can be further enriched. In order to maintain viscosity and form stability, a water-soluble polymer such as natural gum or carboxyvinyl polymer system such as xanthan gum, acrylic acid, alkyl methacrylate copolymer, and ammonium acryloyl dimetyl taurate / vinyl copolymer is used Respectively. In addition, these materials were selected because nonionic surfactants in liquid or paste rather than solid nonionic surfactants are useful for making the formulations transparent.

In the composition according to the present invention, the moisturizing agent is preferably contained in an amount of not less than 35% by weight in order to improve the moisturizing power and increase the transparency of the formulation, and preferably not more than 50% by weight in order to prevent a somewhat tacky feeling. As the kind of humectant used in the present formulation, it is preferable to use at least two kinds selected from the group consisting of glycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol and sorbitol.

In the composition according to the present invention, the above-mentioned higher alcohol is preferably contained in an amount of not less than 0.3% by weight for the purpose of formulation stability. When the content of the higher alcohol is high, the hardness of the formulation is increased, Do. These higher levels of alcohols improve the formulation stability of the cosmetic as well as the surfactant. It is preferable to use at least one selected from the group consisting of cetyl alcohol, stearyl alcohol, cetostearyl alcohol, behenyl alcohol and the like as the higher alcohol used in the present formulation.

In the composition according to the present invention, the water-soluble polymer is preferably contained in an amount of not less than 0.1% by weight for maintaining the viscosity of the formulation and stability of the formulation, and if the content is high, . The water-soluble polymer used in the present invention includes at least one selected from the group consisting of xanthan gum, carboxyvinyl polymer, ammonium acryloyldimethyltaurate / Vpicopolymer, acrylic acid, alkyl methacrylate copolymer, and the like .

In the composition according to the present invention, the nonionic surfactant is preferably contained in an amount of 0.1 to 5.0% by weight or less in order to improve the formulation stability. The surfactant classes used in this formulation include polyglyceryl-2 distearate, phage-5 glyceryl stearate, phage-10 glyceryl stearate, sorbitan sesquioleate, phage-60 hydrogenated castor Oil, and polysorbate 60 is preferably used.

In the composition according to the present invention, the kind of the oil component is not particularly limited, and a common oil used in the cosmetic composition may be used. Specifically, hydrocarbon-based oils including hydrogenated polydecene, squalane and mineral oil; Caprylic / capric triglyceride, neopentyl glycol dicaprate, 2-octyldodecyl myristate, isopropyl myristate, cetyl 2-ethylhexanoate, octyldodecanol, and triethylhexanone Based oil; Olive oil, jojoba oil, and vegetable oil including macadamia oil. These oils generally have a viscosity higher than that of ester oil or vegetable oil, which is a polar oil when using a non-polar hydrocarbon-based oil. Therefore, proper formulation according to the degree of polarity should be considered.

In addition, the composition according to the present invention may contain the oil component in an amount of 1 to 10% by weight. That is, the oil component is preferably contained in an amount of 1 wt% or more for the stability of the formulation and 10 wt% or less for the feeling of use.

In addition, the cream cosmetic composition according to the present invention may further contain flavors, pigments, preservatives, bactericides, oxidative stabilizers and the like in addition to the above components within a range not to deteriorate the effect of the composition.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.
