Description

[0001] The present invention relates to a cosmetic composition for improving color and volume of lips,

The present invention relates to a cosmetic composition for lips that improves the color and volume of lips, and more particularly, to a cosmetic composition for lips that is prepared by mixing lycopene, which is known as a strong antioxidant effect, in an oil solvent and stabilizing it by using a lipid complex together, And to improve the color and volume of the lips.

As the aging progresses, the lips become dull and dark and the lips become thin and become poor lips. Therefore, there is a growing interest in making vivid red lips and lumpy lips that are vital to improve the dullness and poorness of the lips, and the demand for related products is increasing. Antioxidant activity is a typical action of anti-aging effect, and antioxidants are known to remove harmful oxygen to remove waste products and to keep blood clean and clean. However, most of the substances having antioxidant activity are difficult to be mixed in a lipstick mainly composed of oil and wax as a main constituent, and most of them are used as a water-soluble substance, so that the effect is insignificant. Korean Patent Laid-Open No. 10-2006-070846 discloses a method for extracting lycopene obtained from tomatoes by a supercritical extraction method and a cosmetic composition for antioxidation containing the method. However, lycopene is an antioxidant having a coloring matter when used in a cosmetic composition for color cosmetics, and is unstable when exposed to light and heat for a long period of time, resulting in ineffective activity and a lack of color, which may change the color of the original appearance of lipstick or lip gloss in the long term.

The present inventors have made efforts to produce a cosmetic composition for lips having antioxidative functions while maintaining the color stability of the form, and as a result, it has been found that when lycopene is mixed with an oil solvent and stabilized, And the lip color and the volume can be improved at the same time, and the present invention has been completed.

Accordingly, it is an object of the present invention to provide a cosmetic composition for lips which improves lycopene color and active retention and continuously improves lip color and volume.

In order to achieve the above object, the present invention provides a lip cosmetic composition containing lycopene stabilized by mixing lycopene with an oil solvent and using a lipid complex together.

The present invention can be used as a composition for external application of lip which can stabilize the color and activity of lycopene by mixing lycopene with an oil solvent and using a lipid complex to maintain the color quality of the external appearance stably for a long period of time. Also, it was possible to improve the lips' volume and the lips' volume at the same time, thereby enhancing the consumers' satisfaction with healthy and beautiful lips.

The present invention provides a cosmetic composition for lips comprising a mixture of lycopene and an oil solvent and a lipid complex as an active ingredient.

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

The present invention can provide a cosmetic composition for lips which is obtained by mixing lycopene with an oil solvent and using a lipid complex to enhance color stability and activity by using stabilized lycopene to simultaneously improve lip color and volume.

Lycopene, which is used as an active ingredient in the present invention, is a strong antioxidant of carotinoid system, and it is known that it removes harmful oxygen generated in living tissue to prevent oxidation of cells to remove waste products and keep blood clean and clean (Nutr Cancer, 2010 Oct; 62 (7): 988-95). However, lycopene itself is unstable when exposed to light and heat for a long period of time, resulting in ineffective activity and color discoloration, which may change the color of the original appearance of lipstick or lip gloss in the long term. Thus, the present invention utilizes lycopene as an oil solvent to stabilize it for use with an oil base, and then mixes the lipid complex to maximize the effect of improving the color and volume of lips.

The lycopene of the present invention can be obtained by a conventional production method in the art, for example, by refluxing ethanol in a dry tomato, filtering it, and concentrating the separated filtrate under reduced pressure.

As the oil solvent used in the present invention, glyceryl esters are preferred. More specific examples include diisostearyl malate, polyglyceryl-10 nonaisostearate, triisononanoin, dipentaerythritol pentaisononanoate (diisostearyl malate, Dipentaerythrityl Pentaisononanoate).

The oil solvent used in the present invention may be contained in an amount of 50 to 98% by weight, preferably 60 to 80% by weight, based on the weight of lycopene alone. If it is less than 50% by weight, it is difficult to dissolve, and if it is more than 98% by weight, the efficacy of lycopene is insignificant.

The composition of the present invention contains a mixture of lycopene and an oil solvent in an amount of 0.001 to 10% by weight based on the total weight of the composition. If the content is less than 0.001% by weight, the effect of lycopene can not be sufficiently obtained. If the content is more than 10% by weight, the effect is insignificant as the content increases.

The lipid complexes used as active ingredients in the present invention include retinyl palmitate and tocopherol. Retinyl palmitate and tocopherol are known to have the effects of wrinkle improvement (Vitam Horm. 2007; 75: 223-56) and cell renewal (Clin Exp Rheumatol 2009 May-Jun; 27: 51-4).

In one embodiment of the present invention, commercially available oil containing retinyl palmitate and tocopherol (Cognis, Monheim, Germany) is used, but the present invention is not limited thereto and can be used in any form.

The lipid complex of the present invention is contained in an amount of 0.001 to 5% by weight, preferably 0.1 to 1% by weight, based on the total weight of the composition. When the content is less than 0.001% by weight, it is difficult to obtain a sufficient effect. When the content is more than 5% by weight, the effect of increasing the content is insignificant. When the lipid composite is dispersed in oil and thickener, it is contained in an amount of 0.01 to 10% by weight, preferably 0.1 to 5% by weight.

In the present invention, by using the lipid complex together with lycopene stabilized in an oil solvent, it is possible to maximize the long-term stability of the pigment of the lipstick appearance and the effect of increasing the color and volume of the lip.

The lip cosmetic composition according to the present invention may contain from 5 to 60% by weight of at least one oil selected from the group consisting of waxes in an amount of 0.1 to 20% by weight, an ester-based oil and a hydrocarbon-based oil based on the total weight of the composition .

The waxes used in the present invention are not particularly limited as waxes used in cosmetic compositions, and specific examples thereof include carnauba wax, candelilla wax, bees wax, paraffin wax, wood wax, ceresin and microcrystalline wax . The waxes are blended in an amount of 0.1 to 20% by weight, more preferably 1 to 15% by weight, based on the total weight of the cosmetic composition for lips. When the content of the waxes is less than 0.1% by weight, it is difficult to maintain the viscosity and hardness to ensure stability. When the content of the waxes is more than 20% by weight, the feeling of use of the final lip cosmetic composition tends to be stiff and dripping.

The oils are not particularly limited as the oils used in the cosmetic composition, but preferably hydrocarbon-based oils or ester-based oils having good compatibility can be used. Specific examples include glycerin esters such as tri-2-ethylhexyl glycerin, castor oil, liquid paraffin, caprylic / capric triglyceride, triglyceride, myristyl lactate, octandodecanol, diisostearyl malate, Stearate, C13-18 acid triglyceride, isopropyl isostearate, triisostearin and trimethylpentafethenyl trisiloxane. The oils are blended in an amount of 5 to 60% by weight, more preferably 20 to 40% by weight, based on the total weight of the cosmetic composition for lips. If the content of the oils is less than 5% by weight, the feeling is sticky and stiff. If the content is more than 60% by weight, the feeling of smearing and slippery is deteriorated.

The lip cosmetic composition of the present invention may further contain silicone oil, silicone gel, moisturizer, preservative, polymer, ultraviolet absorber, extender pigment, pearl pigment or fragrance in addition to the above components.

The lip cosmetic composition according to the present invention is not particularly limited in its formulation, and may be formulated into, for example, lipsticks, lip gloss or lip balm.

The present invention will be described in more detail with reference to the following examples and test examples. It is to be understood, however, that the following examples and test examples are provided only to facilitate understanding of the present invention, and that the scope of the present invention is not limited by these examples and test examples in any sense.

[Referential Example 1] Preparation of lycopene extract

To 1 kg of dry tomato, 6 l of 80% ethanol was added, refluxed for 3 times, and then immersed at 45? For 3 days. Thereafter, the residue and the filtrate were separated by filtration and centrifugation through filter cloth, and the separated filtrate was concentrated under reduced pressure to obtain 600 g of lycopene extract.

The obtained lycopene extract was mixed with diisostearyl malate at a low temperature (30 DEG C) with diisostearyl malate at a low temperature (30 DEG C) for a long period of time, and the pigment dispersibility was confirmed by a microscope (Figs. From the results of FIGS. 1 and 2, it was found that when lycopene was mixed with an oil solvent, compatibility and color dispersibility were increased.

[Test Example 1] Antioxidant effect of oil solvent of lycopene

In order to confirm the antioxidative ability of lycopene after mixing with oil solvent and keeping the lycopene extract at room temperature for one month after heating, the following experiment was conducted.

The DPPH method was used, and the DPPH (1,1-diphenyll-2-picryl-hydrazyl) reagent was purchased from Sigma (St. Louis, Mo., USA). Since this reagent is present as a relatively stable free radical, it is used as an in vitro method in the process of confirming free radical scavenging action. The concentration of each plant extract measured by DPPH free radical scavenging activity measurement was set at 1 volume%. The extracts of the above concentrations were placed in a 96-well plate, and DPPH prepared from a 100 M ethanol solution was added thereto to make the total volume of the solution 200 μl. After incubation at 37 ° C for 30 minutes, the absorbance at 520 nm was measured with an ELISA reader. The free radical scavenging activity (%) was calculated by the following equation (1) and the results are shown in Table 1. This is the result obtained by averaging the values obtained by repeating the experiment four times.

[Equation 1]

Free radical scavenging activity (%) = 100- (B / A) * 100

A: The absorbance of the control well without the extract of the present invention

B: Absorbance of the experimental group well treated with the extract of the present invention

division Free radical scavenging activity (%) A mixture of lycopene and an oil solvent 89 Lycopene extract, which is one month old after warming 50 Refrigerated lycopene extract 94

As can be seen from Table 1, the antioxidative effect of the mixture of lycopene and oil solvent was maintained for a long time even after one month of heating, whereas when the lycopene extract alone was used, the antioxidative effect was drastically decreased.

 [Example 1 and Comparative Examples 1 to 4] Preparation of lipstick

The lipsticks of Example 1 and Comparative Examples 1 to 4 were prepared according to the compositions shown in Table 2 below (unit: wt%). Lycopene extract was used alone, and lycopene extract and oil solvent mixture were mixed with diisostearyl malate 1: 9 at low temperature (30 ° C). Lipid complexes were prepared by mixing retinyl palmitate and tocopherol in a 1: 2 ratio (Cognis, Monheim, Germany).
