Description

[0001] Cosmetic composition [0002]

The present invention relates to a warm cosmetic composition, and more particularly, to a cosmetic composition comprising a continuous phase containing oil; And a non-crystalline phase containing a polyhydric alcohol.

Around the nose, the ball and the jaw of the skin, a lot of wastes such as sebum and keratin are piled up. In particular, the blackhead in which sebum in the pore is shrunken can be easily seen. It is effective to remove the sebum in the pores by hydrophobic substance as an oil-soluble substance. In order to remove the sebum deeply in the pores, it is effective to open the pores by removing the pores by giving a thermal sensation. In addition, hyperthermia has been used to activate metabolism in the skin or effectively penetrate the active ingredient. Therefore, there is a need to develop a cosmetic composition which can effectively impart a thermal sensation to the skin.

Conventional heat / fever cosmetics mainly include synthetic zeolite, which is a kind of allimonosilicate mineral, as a pyrogenic raw material, and polyhydric alcohols such as glycerin, butylene glycol and polyethylene glycol as pyrogenic raw materials And the type used.

For example, Korean Patent Laid-Open No. 10-2004-0056159 proposes a non-lactating cosmetic composition containing zeolite as an exothermic raw material. However, in the case of using zeolite, the reaction with water causes heat to be generated within a short period of time, so that it is difficult to expect continuous and high heat effect.

Korean Patent Laid-Open No. 10-2006-0059854 discloses an inorganic chloride in the form of a sheet containing an inorganic chloride such as sodium chloride, potassium chloride, magnesium chloride, calcium chloride, potassium sulfate, magnesium sulfate, sodium sulfate or the like as a heat generating substance And a heating element which adheres to the skin. However, when such an inorganic chloride is applied directly to the skin as a form of cosmetic composition, magnesium chloride may cause skin irritation and the reaction with water or oxygen may cause instantaneous exothermic reaction. .

Further, Korean Patent No. 10-0633022 relates to a cosmetic composition for a warmer of the type of oil in polyalcohol, which comprises a continuous phase which is a water phase containing a polyhydric alcohol, and a non- Lt; / RTI > This is a composition which exerts a heat effect using the heat of hydrolysis of polyhydric alcohol, but the cosmetic composition using the polyhydric alcohol hydration heat has a disadvantage in that the feeling of use is poor or the heat effect is poor. Particularly, the composition is a non-aqueous cosmetic composition consisting of a polyhydric alcohol continuous phase and an oil non-aqueous continuous phase. Although there is a thermal effect, the presence of polyhydric alcohol in the continuous phase increases the chance of contact with moisture in the air, There is a problem that the effect may be reduced. Therefore, there is a disadvantage that it is necessary to use a special container for blocking water in the air to solve this problem.

Under these circumstances, the present inventors have made intensive efforts to develop a cosmetic composition for imparting a thermal sensation that can solve the above problems, and as a result, they have found that a cosmetic composition comprising a continuous phase containing oil and a non-crystalline phase containing a polyhydric alcohol And confirmed that the composition had excellent thermal sensation and skin moisturizing effect, thereby completing the present invention.

When the cosmetic composition is applied to the skin, polyhydric alcohol dispersed in a non-condensed state reacts with moisture of the skin to generate hydration heat, thereby giving the user a sense of warmth.

Example  2. Cosmetics  Comparison of thermal effects of composition

Table 3 shows the measurement results of the cosmetic composition (lotion formulation) prepared in accordance with the composition ratio shown in Table 1 of Example 1 with the evaluation criteria of Table 2 below.

Thermal effect evaluation standard Item No thermal effect Weak heat effect The warm effect is usually Strong thermal effect score 0 One 2 3

Thermal effect evaluation result Item Experiment 1 Experiment 2 Control 1 Control group 2 Control group 3 score 3 2 0 One 1.5

As shown in Table 3, in the case of the control group 1 in which the oil was a non-continuous phase, water was not included, and the control group 2 and 3 without water had no heat effect. In comparison, the experimental groups 1 and 2, in which the oil according to the present invention was a continuous phase, showed better thermal effects than the control groups 1 to 3, and in particular, the experimental group 1, It was evaluated to be excellent.

Example  3. Cosmetics  Of the composition Moisture power  Compare effects

In order to measure the moisturizing effect of the cosmetic composition (lotion formulation) prepared according to the composition ratio shown in Table 1 of Example 1, a method of evaluating the water holding ability after applying a fixed amount to the skin was used.

In the test method, a predetermined amount (2 mg / cm 2) of the compositions of Experimental Groups 1 and 2 and Control Groups 1 to 3 was applied to the inside of each arm of 20 subjects in a constant temperature and humidity room at 22 ° C and 45% RH, The short-term effect was evaluated by measuring the water increase rate (%) after 1 hour and 3 hours based on the water holding ability at 0 hour.

At this time, a device used to measure the water holding ability was Skicon 200 (high frequency: 3.5 MHz), a skin moisture content measuring device for measuring the electrical conductivity of the skin. The Skicon 200 is a device for measuring the moisture content of the skin (corresponding to the keratinocyte layer) with a shallow thickness at a frequency of 3.5 MHz.

 The results obtained are summarized in Table 4 below.

Results of moisturizing effect measurement Experiment 1 Experiment 2 Control 1 Control group 2 Control group 3 0 hours 0 0 0 0 0 1 hours 234 152 88 120 136 3 hours 233 150 90 118 130

As can be seen from the above Table 4, it can be confirmed that the increase rate of water retention after one hour and three hours after application is much higher than that of the control groups 1 to 3. Particularly, in experimental group 1, the water uptake rate was nearly doubled.

Example  4. Cosmetics  Cleansing of the composition ( Cleansing ) Comparison of effects

In order to measure the moisturizing effect of the cosmetic composition (lotion formulation) prepared according to the composition ratio shown in Table 1 of Example 1 above, 20 women were evaluated for their cosmetic compositions at the same level as usual The results are summarized in Table 6.

Evaluation standard Item Very unsatisfactory degree of cleansing Dissatisfied with cleansing Satisfy degree of cleansing Satisfy degree of cleansing score 0 One 2 3

Cleansing effect evaluation result Experiment 1 Experiment 2 Control 1 Control group 2 Control group 3 score 3 3 0 One One

As can be seen from the above Table 6, it can be seen that the test groups 1 and 2 have significantly higher cleansing effects than the control groups 1 to 3. This may be due to the excellent thermal effect of experimental groups 1 and 2.

In the above results, 0.1 to 60% by weight of the continuous phase containing the oil according to the invention; And 40 to 99.9% by weight of a non-emulsion phase containing polyhydric alcohol (Experimental Groups 1 and 2) had excellent thermal effects, moisturizing power and cleansing effect.
