In the modern age, due to changes in living environment and eating habits, regardless of gender and age, interest in skin beauty is heightened, and awareness and desire for healthy skin are also increasing. In particular, the symptoms of aging, which is mainly caused by wrinkles as a result of aging, and dryness and deterioration in elasticity due to aging have become very troublesome. Due to the troubles of modern people, moisturizing and elasticity- In the United States.

Aloe, known as a typical natural moisturizer, is rich in polysaccharides and amino acids of various sizes and is excellent in skin protection and moisturizing effect due to natural moisturizing factors, and has been used as a raw material for cosmetics since early on and is widely used for health supplements (Eshun K , He Q (2004), Aloe vera: A valuable ingredient for the food, Pharmaceutical and Cosmetic Industries-A review, Critical Reviews in Food Science and Nutrition 44: 91-96). Aloe is more than 98% water-soluble and the rest is solids such as carbohydrates and amino acids, proteins, vitamins and minerals of monosaccharides and polysaccharides (Ramachandra CT, Rao PS (2009), Equilibrium sorption isotherms of aloe vera gel powder. Transactions of the ASAE 52: 901-906). Among them, aloe vera gel is composed of polysaccharides and its main constituent is glucomannans, which is acetylated mannan, and also xylose, rhamnose, galactose, arabinose, lupeol, cholesterol, campesterol and β-sitosterol (Hamman JH. of aloe vera leaf gel. Molecules 13: 1599-1616 (2008)). Anthraquinones is the main phenolic component and exists in the form of glycosidic and free bound glycans. The yellow exudates of aloe vera contain free anthraquinones and their derivatives, isobarbloin, anthrone C-glycosides and chromones. As a class of chromones, 8-C-glycosyl-7-O methyl- (S) aloesol, isoaleroin D and aloeresin E have been reported (Rebecca W, Kayser O, Hagels H, Zessin KH, Madundo M, Gamba N.

The emulsion is divided into O / W (oil in water) type in which the oil phase is dispersed in the water phase and W / O type in which the water phase is dispersed in oil phase. The O / W type has a disadvantage in that it is generally used as a general cosmetic formulation due to its relatively light feeling, quick absorption, and easy manufacture because it is an external wound. On the other hand, the W / O type is highly resistant to water because the trauma is oil, and the oil on the trauma forms an oil film on the skin to prevent evaporation of moisture on the surface of the skin. However, O / W type emulsion products are dominant due to difficulty in securing emulsion stability.

The inventors of the present invention have studied to develop a W / O cosmetic material having excellent moisturizing power and improved elasticity. As a result, when a combination of aloe vera and a W / O type having excellent moisturizing and sustaining ability is synergistic effect The present invention has been completed.

[ Example ]

Example : Aloe Vera containing W / O type emulsion  Produce

(Phase 1 and phase 2) were heated and dissolved to 65 占 폚 at the composition ratios shown in Table 1 below. Further, the water phase (phase 3) prepared by dissolving by heating to 65 ° C was slowly added to the oil phase, mixed and uniformly dispersed at 65 ° C and 3,500rpm for 5 minutes, and then cooled to 50 ° C. To this was added Aloe vera, a large resin extract (Phase 4) and an additive (Phase 5), and the emulsion was prepared by slowly cooling at room temperature in a collector.

Experimental Example  1: Continuous moisturizing experiment of aloe, honey and cucumber

Fresh aloe leaves were washed, washed and crushed. Crushed aloe and honey were prepared by diluting 10% of acacia honey with purified water. Crushed organic cucumbers were prepared, ℃, 10 healthy women in their twenties were selected, and 0.5 ml / cm ^{2 was} applied to the ball area of the subject to measure the moisture holding ability. The moisture content of the skin surface was measured by a static capacitance measurement method using a Corneometer CM825 (Courage + Khazaka electronic GmbH).

As shown in Table 2 and FIG. 1, aloe was proved to be superior in moisturizing durability to the control group, and it is considered that the polysaccharide components of aloe have increased moisture retention.

Experimental Example  2: Percutaneous water loss ( TEWL ) evaluation

Devices for measuring transepidermal water loss (TEWL) were DermalLab  TEWL Probe (CORTEX TECHNOLOGY) was used, and the aloe vera-containing W / O type emulsion prepared in Example was displayed at a position 3 cm away from the forearm elbow and was measured by applying Control and Emulsion.

The subjects were 15 healthy 20 ~ 30s who had no history of atopic or allergic contact dermatitis and no skin disease at present.

The measurement of transdermal water loss was repeated three times in total and the average value was obtained. After each measurement, the probe was wiped with a soft tissue. The probe was perpendicular to the measurement site, and the measurement probe was measured while keeping it horizontal for more than 15 seconds with a constant pressure to the skin.

The amount of transdermal water loss was measured on the skin that had not been applied with the control group, and the amount of transdermal water loss was measured three times at 1 minute intervals after 30 minutes of application of the emulsion.

As shown in Table 3 above, a difference of up to 4.3 was observed for all 15 subjects compared to no application. It was judged that the W / O type emulsion containing aloe vera in dry skin restored the moisture content.

Experimental Example  3: Stability test

The stability (appearance, flavor, hardness, etc.) of each aloe vera and W / O type emulsion containing the extract of aloe vera produced in the Examples was maintained for 5 months at 4, 25, Month, 2-month, 3-month, 4-month, and 5-month intervals, and then stored at -20, 25, 50, and 25 ℃ for 24 hours, .

The hardness was measured by using a SUN SCIENTIFIC RHEO METER COMPAC-100 and setting the conditions of Mode 20 Max 2 kg, R / H hold 10.0 mm, and 60 mm / min.

As a result of measuring the product stored under severe condition (-20, 25, 50, 25 ℃) with hardness meter, hardness was relatively stable even under severe condition, And it was judged that the physical properties of the product were stable even for a long period of 5 months.
