According to a specific example, the cosmetic composition is a skin moisturizing cosmetic composition comprising a seed gel as an active ingredient. In another embodiment, the skin moisturizing cosmetic composition may further include "agave syrup" as an active ingredient. In another embodiment, the skin moisturizing cosmetic composition may further comprise one or more selected from the group consisting of poly-gamma-glutamic acid, glucan, and hyaluronic acid. A compound such as acid) is used as an active ingredient. The skin moisturizing cosmetic composition provides superior moisturizing effect and a small stickiness.

In a specific example, the seed gel may comprise from 0.001 to 20% by weight, particularly from 0.5 to 3.0% by weight, more specifically from 1.0 to 1.5% by weight, based on the total weight of the composition. The range of gel content of the above-mentioned crops is to minimize stickiness while providing excellent moisturizing effect.

In another embodiment, the agave syrup may comprise from 0.001 to 20% by weight, in particular from 1 to 10% by weight, based on the total weight of the composition, more specifically It is 5% by weight. Adding agave syrup to the seed gel reduces stickiness and provides a refreshing sensation.

In addition to the crop gel and the agave syrup, the composition may further include one or more compounds selected from the group consisting of poly-γ-glutamic acid, dextran, and hyaluronic acid. In a specific example, the crop gel, agave syrup, poly-γ-glutamic acid, and hyaluronic acid may add up to 0.1 to 30% by weight based on the total weight of the composition; but are not particularly limited to this range. .

The seed gel is obtained by separating water-soluble polymers from the seeds of the Aztec crops originating in Mexico. After contact with water, the seeds can absorb up to 12 times their own weight and expand. Therefore, it feels full and reduces eating. The transparent viscous material around the seeds can effectively eliminate the feces in the intestines in the medium and long term. In addition, it contains about 60% omega-3-fatty acids and is an excellent slimming agent; it promotes metabolism and burns fat. In addition, Jiayou oil is also used as a moisturizer, and the seed gel is usually used to treat fever or wound healing. The composition according to a specific example contains a moisturizing low molecular weight seed gel as an active ingredient. The average molecular weight of the seed gel is, for example, 500,000 Daltons or less, especially 1000 to 500,000 Daltons, more specifically 150,000 to 250,000 Daltons.

Agave syrup is extracted from the Mexican agave cactus. Agave cactus is about 30% sweeter than sucrose, but its glycemic index is only about 1/3. Therefore, it is often used as a natural sweetener in place of sucrose. In addition to fructose, agave syrup also contains minerals such as iron, calcium, potassium and magnesium. It promotes the proliferation of bifidobacteria and adjuvant treatment of constipation. In addition, it contains "inulins" that eliminate bacterial toxins, helping the stomach and liver to detoxify and renew blood. In particular, agave syrup has an excellent moisturizing effect because it contains 74 to 86% of high quality fructose. The average molecular weight of the agave syrup is, for example, 50,000 Daltons or less, particularly 100 to 50,000 Daltons, preferably 1,000 to 20,000 Daltons.

Poly-γ-glutamic acid (γ-PGA) refers to an anionic amino acid polymer in which the γ-carboxyl group of glutamic acid and the α-amino acid of glutamic acid are linked by a guanamine bond. Poly-γ-glutamic acid is produced from strains of Bacillus , and Bacillus is isolated from, for example, Qingyan; Qingyu is a traditional Korean yeast bean paste made by Jip. Or dry rice, natto (traditional Japanese soybean yeast food) or Gina (kinema - traditional Nepalese soy yeast food). The poly-gamma-glutamic acid produced by Bacillus is edible, water soluble, anionic and biodegradable. In addition, poly-gamma-glutamic acid inhibits the activity of collagenase, removes the stratum corneum of the skin, and makes the skin smooth and moist.

Glucan is a polysaccharide obtained by linking D-glucose monomers by glycosidic bonds; and depending on the position of glucose binding, it can be classified into α-glucan and β-glucan. Glucan activates natural killer cells and thus has an anti-cancer effect. In addition, it has been reported to be effective in reducing the concentration of total cholesterol and low density lipoprotein cholesterol (LDL-C) in the blood.

Β-glucan can effectively reduce the concentration of LDL-C. This is because β-glucan binds to bile acids, thereby increasing the viscosity in the intestine and reducing the reuptake of bile acids. Therefore, it increases the synthesis and secretion of bile acids in the intestine, while at the same time increasing the synthesis of cholesterol in the liver. Alpha-glucans are available from plant starch, while beta-glucans are available from the cell walls of mushrooms, grains and yeast. Α-glucan and β-glucan act to strengthen skin immune cells, which lose their function when aging, thereby maintaining skin elasticity and moisture.

Hyaluronic acid is a mucopolysaccharide found in the dermis and found in body fluids, bovine eyeballs, rooster cockscombs, animal tissues or placenta. In particular, it is present in high concentrations in connective tissue and skin. Hyaluronic acid is widely used in the medical field and cosmetics due to excellent tissue healing and moisturizing effects. For example, outside the plastic surgery Branch, inject it into the connecting bone. In cosmetic surgery, it is injected to eliminate wrinkles. In addition, hyaluronic acid has a very good water holding capacity - it can absorb about 6,000 times its own weight of water. Newborn babies have soft, moisturized skin due to high hyaluronic acid content. Aging causes hyaluronic acid to decrease in the dermis, and the skin becomes dry and forms fine wrinkles. Hyaluronic acid containing hyaluronic acid is often used to reduce dryness and fine lines.

Figure 1 is a comparison of the moisturizing effects of the grape seed gel and hyaluronic acid. The skin moisturizing effect is measured by applying 2.0 mg/cm ² of hyaluronic acid or 2.0 mg/cm ² of the seed gel on the inside of the left forearm. The moisturizing effect was measured using a WSK-P500U instrument (manufactured by Inforward Co., Ltd.), and it was kept in a room at 25 ° C and a relative humidity of 45% for 3.5 seconds. The results showed that the use of crop gel or hyaluronic acid significantly improved the moisturizing effect compared to the control without any moisturizer. The moisturizing effect is maintained for up to 70 minutes.

The cosmetic composition according to a specific example includes a low molecular weight seed gel and agave syrup which provide superior moisturizing effects, and poly-γ-glutamic acid, dextran and hyaluronic acid, thereby improving moisturizing effect and reducing Sticky. It can be formulated into various cosmetic formulations without particular limitation. For example, it can be formulated into cosmetic compositions such as softening lotion, astringent lotion, moisturizing lotion, nourishing essence, nutrient cream, massage cream, serum, eye cream, Eye essence, cleansing cream, cleansing foam, cleansing water, cosmetic bag, gel, make-up powder, foundation, body lotion, body cream, massage oil, body essence, or the like.
