Description

Cosmetics containing aloe microcapsules {Cosmetics containing aloe micro capsules}

The present invention relates to a cosmetic composition comprising an aloe microcapsules, and more particularly, to a cosmetic containing aloe with microencapsulation of the aloe extract to further enhance the physiological activity and cosmetic effects.

Aloe is a medicinal plant belonging to the family Liliaceae and has been widely used in folklore since ancient times due to its various effects. The physiological and cosmetic effects of aloe identified to date are as follows.

1) Promotes blood circulation: Increases the amount of melanocytes and shaded skin, which is caused by blood circulation disorders, promotes blood circulation of capillaries to make clean and bright skin.

2) Improvement of body cell fluid and decomposition of toxic substances in body: Preventing various skin diseases and metabolic disorders by defense mechanism (detoxification) from fatigue and heavy metal contamination

3) Antibacterial ability and sterilization

4) Cell regeneration function: It is a biological component and is involved in skin nutrition supply and skin regeneration due to the large amount of essential ananoic acid and essential fatty acids.

5) Skin moisturizing enhancement: Skin moisturizing effect of natural polysaccharides

6) Skin elasticity enhancement: Skin elasticity is enhanced by supplying nutrients to loose skin cells or structural rearrangement between cells due to skin cell regeneration.

7) Ultraviolet absorption function: Absorbs ultraviolet rays and recovers damaged skin due to the action of organic compounds, minerals, vitamins, anthraquinones, etc.

8) Whitening function

The components of aloe that show this function are as follows.

1) Glucoproteins ----------- Effects on cancer, inflammation and erythema

Alexin a., Alexin b.

2) phenolics ----------- Medical action, antiseptic, antibacterial, antibiotic, anti-inflammatory

Aloe emodin, barbalin, chrysophanil, anathranol, aloesine, anthraquinones

3) polysaccharides ---------- Moisturizing, skin elasticity

Glucose, mannose, galacturonic acid, glucomannins, pectic acid

4) Amino Acids ------------ Essential amino acids essential for cell composition.

Contains 20 to 22 amino acids such as lysine, histidine, arginine, aspartic acid, serine, and glutamine

5) Lipids --------- Cell constituents involved in the regeneration of skin cells

Isoprenoids, alkanes, n-alkyl alcohols, fatty acids

6) Proteins 7) Organic Compounds 8) Minerals (Na, K, Mg, Ca, etc.) 9) Vitamins 10) Anthraquinones 11) Lecithin 12) Enzymes

However, in spite of such various effects, when aloe is extracted as it is, it is added to the cosmetics, the portion absorbed by the dermal transdermal and loss is too large to show its efficacy.

Accordingly, it is an object of the present invention to provide a cosmetic composition containing encapsulated aloe with low transdermal loss.

Another object of the present invention is to complex the aloe to microencapsulate the intercellular lipid and the similar structure to fully exhibit the effects of aloe, such as moisturizing, skin elasticity enhancement.

The object of the present invention is 1 to 3.00% by weight of lecithin, 5 to 10.00% by weight of ethanol, 5 to 10% by weight of capric / capri triglyceride, 5 to 10% by weight of propylene glycol, 10 to 20% by weight of aloe extract, and It is achieved by the cosmetic composition consisting of the remaining purified water.

The cosmetic composition of the present invention is prepared by the following method.

First, aloe vera (Aloe Vera) fresh leaves are washed with purified water and then peeled (development) to obtain an Aloe Vera Gel (Aloe Vera Gel). After grinding the aloe vera gel finely and heated to about 70 ~ 80 ℃ by primary filtration on diatomaceous earth to remove the fiber. The opaque aloe vera gel obtained at this time was filtered secondly with activated carbon while heating at 95 ° C. for 40 minutes, followed by third filtration with diatomaceous earth to obtain a transparent liquid aloe extract. This transparent liquid aloe extract is sterilized at 100 ° C. for 20 minutes to be used for preparing the cosmetic composition of the present invention.

Lecithin, ethanol, capric / capri triglyceride, propylene glycol, purified water and aloe extracted by the above method are mixed and stirred to pass through a fine homogenizer, followed by cooling and defoaming to encapsulate the aloe extract. The aloe extract thus encapsulated is called aloe microcapsules.

When preparing each cosmetic formulation using the cosmetic composition of the present invention, the skin is prepared by uniformly mixing and stirring the aloe microcapsules of the present invention with the skin raw material at room temperature, and the lotion or cream is dissolved in oil by a general emulsification method. Neutralization of the resin component as a thickener through an emulsification process that homogeneously mixes the aqueous phase component and the oil phase component with a general homomixer at a predetermined temperature (75-80 ° C) using an ingredient that becomes an oil phase component and a component dissolved in purified water as an aqueous phase component. After cooling, the preparation is completed by adding aloe microcapsules and defoaming. The amount of the cosmetic composition of the present invention added to each formulation is preferably 10-20% by weight.

Hereinafter, the present invention will be described in more detail with reference to Examples.

Example 1 Preparation of Aloe Microcapsules

Aloe Vera (Aloe Vera) fresh leaves 1kg was washed with purified water and then peeled (development) to obtain an Aloe Vera Gel (Aloe Vera Gel). The aloe vera gel was finely pulverized and heated to 75 ° C. to first filter the diatomaceous earth to remove fibers. The resulting aloe vera gel was secondly filtered with activated carbon while heating at 95 ° C. for 40 minutes, and then thirdly with diatomaceous earth to obtain a transparent liquid aloe extract. This transparent liquid aloe extract was sterilized at 100 ° C. for 20 minutes. After weighing 15g of the sterilized aloe extract, 2g of lecithin, 8g of ethanol, 7.5g of capric / capri triglyceride, 7.5g of propylene glycol, and 60g of purified water were mixed and stirred to pass through a fine homogenizer, followed by cooling and defoaming.

The particle size of the obtained aloe microcapsules was measured using MALVERN and PCS 4700, and the particle size was 0.05-1.00 mu (Fig. 1). Since the size of the particles is too small to be measured by a general optical microscope, a photograph of particles of aloe microcapsule (PHOTOGRAPHING FREEZE-FRACTURE SCANNING ELECTRON MICROSCOPY) taken using a frozen electron microscope is shown in FIG. 2.

Example 2 Moisturizing Force Test

Compared with other moisturizing agents (carbohydrate complex, glycerin), the aloe microcapsules showed better moisturizing power.

Example 3 Skin Transdermal Water Loss Measurement Test

4 shows a result of measuring the percutaneous moisture loss with a moisturizer with TEWAMETER TM210 after applying a known moisturizing agent (molasses extract, portulaca extract) and the aloe microcapsules prepared in Example 1, respectively. Aloe microcapsules showed less loss of transdermal moisture than other moisturizers (molasses extract, guchi extract).

Example 4 Skin Improvement Test

Photographs were taken before and after 1 week of application of the aloe microcapsules prepared in Example 1 using IMAGE ANALYZER, and the results are shown in FIG. 5. Before applying aloe microcapsules, the dead skin was completely removed after application.
