Thermosensitive cosmetic composition < RTI ID = 0.0 >

More particularly, the present invention relates to a thermosensitive cosmetic composition having a phase change property according to a temperature change, and more particularly, to a cosmetic composition containing 0.1 to 2.0% by weight of xanthan gum, 0.15 to 3.0% 0.0 >%< / RTI > to 5.0% by weight of a carob bean gum.

Recently, skin care using hydrogels has been applied in various fields such as cosmetics, skin care, skin care, and skin treatment. Hydrogels are well known as materials suitable for use as a support for controlled release of drugs. This is used as a drug delivery system in which a hormone such as progesterone is contained in a hydrogel as a support and the hormone is gradually released to regulate the amount of hormone delivered into the body. In addition, although the present invention is applied to the field of skin care (skin treatment, skin cosmetics, etc.) using the hydrogel property as described above, it is required that the drug or cosmetic agent contained in the support hydrogel It is merely a function to control.

On the other hand, controlling the drug delivery to the skin while the hydrogel remains in the gel state requires a relatively long time for the drug to penetrate into the skin, and only when the hydrogel is in contact with the skin, . To overcome this, it was all about adding a penetration enhancer to the hydrogel or making a hydrogel of a skin-friendly composition. In general, when applying cosmetics for skin care, unlike the treatment of skin wounds, it is impossible to attach a protection device to the application site, and it should be removed immediately after attaching a protective cap to the skin for a short time. Hydrogels are used to enhance the effect in such skin care, and they are used in the form of a sheet or a patch to be effectively applied to the skin. However, in the gel state, there is a limitation in affinity with the skin, and there is a problem that the cosmetic agent can not have a satisfactory amount and speed to be delivered from the hydrogel to the skin. The affinity between the hydrogel and the skin has a crucial influence on the delivery of the cosmetic agent or drug contained in the hydrogel to the skin. That is, if the affinity is large, the delivery of the cosmetic agent or the drug from the hydrogel to the skin is easy and quick, but if the affinity is low, the delivery is not sufficient and slow.

In addition, when a hydrogel containing a cosmetic agent is used for skin care, the cosmetic agent contained in the hydrogel must be able to be rapidly and rapidly transferred from the hydrogel to the skin. In order to satisfy such characteristics, the hydrogel must have a characteristic that the cosmetic agent is rapidly and uniformly transferred into the skin as compared with the conventional one. Therefore, there is a need for a hydrogel having properties capable of solving the above problems.

Under the above circumstances, the inventors of the present invention have been studying a gel-like cosmetic composition having characteristics capable of improving the skin absorption rate, that the cosmetic composition containing the composition containing xanthan gum, guar gum and a mixture of gum arabic gum is kept in a gel state at a low temperature Which is a skin-like temperature of 30 占 폚 to 34 占 폚.

As used herein, the terms "Xanthan gum", "Guar gum" and "Ceratonia siliqua gum" are natural thickeners that increase stickiness and viscosity and enhance emulsion stability, Stabilizers for foods and cosmetics, thickeners, binders and emulsifiers. The cosmetic composition of the present invention can make a phase change according to the temperature by mixing the xanthan gum, guar gum and kerosene gum at a certain ratio.

The cosmetic composition is a gel having a viscosity of 1,500 mPa s to 20,000 mPa 점 at a temperature of 0 캜 to 5 캜 and a viscosity of 1,000 mPa s to 15,000 mPa 점 at 20 캜 to 25 캜, Preferably in a semi-gel phase. In addition, the cosmetic composition is preferably in the form of a sol having a viscosity of 300 mPa.s to 12,000 mPa.s at 30 ° C to 34 ° C.

According to one embodiment of the present invention, the cosmetic composition containing xanthan gum at 0.300 wt%, guar gum at 0.450 wt%, and kerosene bean gum at 0.750 wt% is easier to make according to the temperature change (5 ° C to 32 ° C; skin-like temperature at low temperature) A difference in viscosity was shown.

In addition, the cosmetic composition preferably further comprises 0.01 to 5.0% by weight of ceramide-3 and 0.01 to 5.0% by weight of hydrogenated lecithin based on the total weight of the composition .

Experimental Example : Viscosity analysis

The viscosity changes of the cosmetic compositions prepared in the above Examples and Comparative Examples were compared and analyzed.

1) Viscosity change according to sword content

The viscosity change analysis of the temperature sensitive cosmetic composition containing the mixture of xanthan gum, guar gum and carob bean gum prepared in Examples 1 to 3 and the cosmetic compositions of Comparative Examples 1 to 6 was performed. Viscosity was measured by a viscometer (DV-E Viscometer, Brookfield) after loading 100 g of each of the above-prepared compositions into a plastic container. At this time, Spindel No. 4 was used for the measurement of the viscometer, and the spindle was immersed in each of the above compositions and rotated at 30 rpm for 1 minute, and the indicated values were used as the viscosities. The results of the viscosity measurement are shown in Table 5 below.

Temperature Viscosity (mPa 占 퐏) Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 5 ℃ 1940 3240 8300 × 11620 11540 2180 2800 2600 25 ℃ 1200 1640 4100 × 8140 9080 1800 1900 1860 32 ℃ 720 1280 2820 × 8020 8880 1740 1720 1720

As shown in Table 5, the cosmetic compositions of Comparative Example 2 and Comparative Example 3 using acrylate / C10-30 alkyl acrylate crosspolymer, sodium polyacrylate or tromethamine, which are commonly used in cosmetics, And the viscosity difference between the skin-like temperature (32 ° C) and the room temperature was almost not observed. In addition, the cosmetic compositions of Comparative Examples 4 to 6 including xanthan gum, guar gum or keratoconch alone did not show a significant difference in viscosity depending on the temperature. On the other hand, the thermosensitive cosmetic compositions of Examples 1 to 3 using the mixture of xanthan gum, guar gum and kerosene gum according to the present invention had a viscosity of 2.5 times or more at low temperature (5 ° C) and skin-like temperature (32 ° C) Respectively. Accordingly, it has been confirmed that the cosmetic composition comprising the mixture of xanthan gum, guar gum and caraway bean gum exhibits an excellent temperature-sensitive effect, so that the composition can be effectively used as a temperature sensitive cosmetic composition.

2) Viscosity analysis with addition of ceramide and hydrogenated lecithin

The viscosity of the thermosensitive cosmetic composition prepared in Examples 4 to 6 was compared and analyzed in order to confirm the gel-like keeping effect at low temperature by addition of ceramide and hydrogenated lecithin. The viscosity analysis was carried out in the same manner using the same equipment as in Experimental Example 1-1. The results of the analysis are shown in Table 6 below.

Temperature Viscosity (mPa 占 퐏) Example 4 Example 5 Example 6 5 ℃ 2300 3240 3660 25 ℃ 1580 1640 1840 32 ℃ 1240 1280 1320

As shown in Table 6 above, the addition of ceramide and hydrogencontained lecithin did not significantly affect the viscosity change with temperature. However, it was confirmed that addition of a small amount at low temperature (5 ° C) helps to improve the viscosity. Thus, it is believed that the inclusion of ceramide and hydrogenated lecithin will be effective in maintaining the gel phase of the cosmetic at low temperatures.

Experimental Example  2: Sensory evaluation

The sensory tests of the cosmetic compositions prepared in the above Examples and Comparative Examples were carried out. The sensory test was carried out on 20 female subjects in their 30s, and the cosmetic composition prepared in the above Examples and Comparative Examples was used at the basic makeup stage after evening cleansing for two weeks for two weeks. After the observation period of 2 weeks, the feeling of satisfaction was measured by the questionnaire and the test results are shown in Table 7 below.
