Description

[0001] The present invention relates to a cosmetic composition comprising a low melting point butter or a wax,

The present invention relates to a cosmetic composition comprising a low melting point butter or wax, and more particularly to a cosmetic composition comprising a low melting point butter or a wax, which is excellent in stability under refrigerated distribution conditions and further contains starch, ethanol, fructose or a combination thereof The present invention relates to a high hardness cosmetic composition excellent in stability at room temperature and refrigerated distribution conditions as well as high temperature conditions and excellent in feeling such as spreadability.

If you look at the current products, hardness cream is formed by using almost fatty alcohol or wax. In the case of a cosmetic directly applied to the skin, there was no cosmetic characterized by using only a low-melting-point high-hardness butter and dissolving it before and after coating, and having characteristics such as being circulated and used at room temperature. When producing commercially available lotions, essences, creams or the like in the form of a high-hardness butter or a wax, there is a problem that the hardness tends to increase and the spreadability is poor. In particular, in the case of cream, most of wax-shaped raw materials are used in order to enhance feeling of nourishing feeling and moisturizing ability, viscosity and hardness are drastically increased and spreadability is greatly lowered. Respectively.

The present inventors have conducted studies to solve the above problems. As a result, the present inventors have found that, in the refrigerated condition of room temperature distribution cosmetic materials, when the viscosity and hardness are drastically increased and the spreadability is greatly deteriorated, . It is difficult to exclude the use of wax as a necessary raw material, such as forming a moistening film after the application to the skin to prevent dryness of the skin and giving a luster to the skin. The present inventors have found that waxy raw materials having a melting point of 40 DEG C or higher among the raw materials on the wax cause this problem more seriously and raw materials having a low melting point waxy phase below 40 DEG C do not cause the above problems.

Accordingly, the present inventors have filed a patent application for an emulsified cosmetic composition containing a wax phase component having a melting point of 20 to 40 ° C and imparting a thickening and moisturizing property in an amount of 2 to 10% by weight (Korean Patent Laid-Open Publication No. 10-2012-0076169 number). However, the cosmetic composition has to be limited to 10% by weight or less of the wax phase component in order to provide a satisfactory leveling ability to the user during application of the skin.

The present inventors have also found that an oil-based anhydrous cosmetic composition containing no water or not more than 1% by weight of water and not containing a surfactant can be used as an oil-based cosmetic composition containing a low melting point waxy raw material having a melting point of 25 to 35 DEG C To 30% by weight of a cosmetic composition for refrigeration storage (Korean Patent Publication No. 10-2013-0012596). However, the above cosmetic composition is limited in diversification of formulations as an oil-based cosmetic composition.

Under these circumstances, the present inventors have found that additional components are required to have excellent high-temperature stability. Thus, using starch, ethanol, fructose, or the like, the shape, It is possible to produce a cosmetic composition which can further enhance the efficacy of the active ingredient.

An object of the present invention is to provide a high-hardness cosmetic composition which is excellent in stability under refrigeration circulation and high temperature conditions and is excellent in feeling such as spreadability.

In order to solve the above problems, the present invention provides a cosmetic composition characterized by containing a low-melting-point, high-hardness butter or a wax-like raw material at 40 ° C or less in an amount of 10% by weight to 50% by weight based on the total weight.

The cosmetic composition of the present invention is a shear thinning high-hardness cosmetic composition comprising a low-melting-point high-hardness butter or a wax-like raw material at 40 ° C or lower. That is, unlike most of the cosmetic compositions do not dissolve when applied, the cosmetic composition of the present invention melts by applying hand force when applying the skin using a low-melting-point, high-hardness buttery or waxy raw material having an average temperature of 40 ° C or less and an average temperature of 20 to 40 ° C Is a shear thinning type high hardness cosmetic composition used.

Further, the present invention is characterized in that it comprises 10.0 wt% to 50.0 wt% of a low-melting-point, high-hardness butter or waxy raw material at 40 ° C or less.

If less than 10.0% by weight of the low-melting-point high-melting butter or wax-like raw material at 40 ° C or lower, a feeling of good feeling of use, moisturizing effect and hardness formation is not sufficiently exhibited. If it is more than 50.0% by weight, There is also a problem with stability.

The cosmetic composition of the present invention has an advantage that it can be applied to products requiring high moisture-holding power and absorbing power, because the content of raw materials in a low-melting point and high-hardness buttery or wax at 40 ° C or lower can be variously applied up to 50.0 wt% .

As used herein, the term "low-melting-point high-hardness buttery or waxy raw material at 40 DEG C or lower" means raw material in butter or wax having a low melting point of 40 DEG C or lower but exhibiting high hardness at room temperature and existing in a solid state. In the present invention, a low melting point of 40 DEG C or lower may mean a low melting point of 20 to 40 DEG C on average. The low melting point buttery or waxy raw material of 40 ° C or less of the present invention exhibits a high degree of hardness at the time of refrigeration or circulation at room temperature but is melted before and after application of the skin due to a low melting point of 40 ° C or less.

As for the cosmetics currently in circulation at room temperature, raw materials of a high-melting-point wax at a temperature of 40 ° C or higher and low-melting waxes of a temperature of 40 ° C or lower are widely used for various purposes without selecting a melting point. However, raw materials having a high melting point of 40 ° C or higher have problems as mentioned above, and raw materials having a low melting point of 40 ° C or lower should be used.

Specific examples of the low-melting-point, high-hardness buttery or waxy raw materials usable in the present invention include vegetable oils such as shea butter, cucumber butter, barba soap butter and cacao butter, lanolin and bis-phage-18 methyl Hydrocarbons such as paraffin and vaseline, esters, and the like, and at least one of them may be selected, but is not limited thereto. In the examples of the present invention, shea butter, cucumber butter and barberry soap butter were used.

In the experimental example of the present invention, when the low melting point high-hardness butter or the wax-like raw material having a melting point of 40 ° C or less is used, the difference in viscosity between the room temperature and the refrigerated state is not large compared with the case of using the high melting point wax- (Comparison between Example 1 and Comparative Example 2 of Experimental Example 1), and skin moisturizing power was not lowered (comparison between Example 1 of Experimental Example 3 and Comparative Example 1).

In addition, the cosmetic composition of the present invention may further comprise starch. In particular, the present invention relates to a method for preventing the separation of a high content of butter from a high temperature by utilizing amphipathic nature of starch, and a method for producing a stable active ingredient without deteriorating shape, spreadability and basic effect The effect can be further enhanced.

Preferably, the starch may comprise from 1% to 20% by weight of the total weight of the cosmetic composition.

If the amount of the starch is less than 1 wt%, the stability tends to deteriorate. If the amount of the starch is more than 20 wt%, the spreadability and feeling of use are deteriorated.

The starch usable in the present invention may be, but is not limited to, one or more starches selected from starches derived from tapioca, rice or corn.

In the Experimental Example of the present invention, the stability at high temperature is higher than that in the case where starch is not used together with the low-melting-point, high-hardness buttery or waxy raw material and starch at 40 ° C or less (Example of Experimental Example 2 1 and Example 2-4) was confirmed.

In addition, the cosmetic composition of the present invention may further dissolve a portion of the butter by using a point that is more non-polar than water, including ethanol, so that the cosmetic containing a large amount of butter can be prevented from being rapidly hardened, Thereby making it possible to efficiently apply the starch to the formulation without aggregation.

Preferably, the present invention comprises ethanol in an amount of 3.0 wt% to 30 wt% based on the total weight of the cosmetic composition.

If the amount of ethanol is less than 3.0% by weight, hardness is not formed well and the spreadability is deteriorated. If the amount is more than 30% by weight, stability is lowered.

In addition, the cosmetic composition of the present invention may further comprise fructose. In particular, by using ethanol, starch, and fructose together, it is possible to prevent jams and the like which may occur when a large amount of starch is used, so that a stable active ingredient can be obtained without sacrificing shape, The effect can be further enhanced.

Preferably, the present invention includes fructose in an amount of 1 wt% to 10 wt% based on the total weight of the cosmetic composition.

If the fructose content is less than 1% by weight, there is a disadvantage that the starch can be pushed. If the fructose content is more than 20% by weight, the spreadability and feeling of use are deteriorated.

The fructose which can be used in the present invention may be, but is not limited to, fructose including one or more fructose selected from fructose derived from agave or millet.

In the experimental examples of the present invention, when fructose was used together with raw materials such as low-melting-point, high-hardness butter or wax-like raw materials, starch and ethanol at 40 ° C or less, (Experimental Example 4).

The cosmetic composition of the present invention can be provided in formulations such as basic cosmetics, makeup cosmetics, body cosmetics, hair cosmetics, and scalp cosmetics. The formulations of the basic cosmetics include creams, packs, nutritional creams, massage creams, cleansing creams, cleansing foams, and the formulations of body cosmetics include sunscreen creams. The makeup cosmetics include foundation, makeup base, Hair cosmetics such as hair treatments, hair color preparations and hair blisters, and scalp treatments such as scalp cosmetics.

The cosmetic composition of the present invention can also suitably be added with additives commonly used in the cosmetics field depending on the use thereof. Common additives in the cosmetics field include one or more selected from the group consisting of flavorings, coloring matters, bactericides, antioxidants, preservatives, moisturizers, thickeners, inorganic salts, synthetic polymers, oils, water, surfactants, alcohols and chelating agents .

The present invention provides a cosmetic composition in which a cosmetic preparation is stably maintained even in cold and high-temperature circulation conditions by including a low-melting-point, high-hardness butter or wax-like raw material at 40 ° C or lower in an amount of 10 wt% to 50 wt% There is an effect that can be. Further, the present invention can further include starch to prevent a high content of butter or wax from being easily separated at high temperatures. In addition, the cosmetic composition of the present invention can further prevent the cosmetic containing a large amount of butter from being hardened by further containing ethanol and make the starch more dispersible than water, so that the starch can be efficiently applied to the formulation without aggregation Let's do it. Further, the present invention can further enhance shape and spreading property to maintain the quality of a high-hardness product by preventing fuzziness and the like which may occur when a large amount of starch is used including fructose.
