Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a cream composition, and more particularly, it is capable of providing various nutritional ingredients to the skin, promoting skin metabolism, and imparting smoothness and moisture to the skin surface. Relating to cream compositions.

Technical background of the invention and its problems The skin consists of the epidermis, dermis and subcutaneous tissue.
It has a variety of functions, including acting as the outer skin of the human body to protect internal organs from appearance, sensory function, body temperature regulation, and substance metabolism. When such skin is exposed to harmful stimuli directly from the outside world, the skin epidermis becomes rough, resulting in so-called rough skin, rashes, etc.
Symptoms called sores may appear. Alternatively, the skin may become dry and flaky due to a decrease in the skin's moisturizing function.

It is widely practiced to apply cream compositions to skin in such rough conditions. Cream compositions are applied to the skin, particularly the outermost layer of the stratum corneum, and are used to moisturize the skin, promote blood circulation to the skin, cleanse the skin, and the like.
In addition to cosmetic skin creams such as those described above, cream compositions with special purposes have also been developed. Cream compositions with such special purposes include, for example, ultraviolet protection creams to prevent moderate sunburn on the skin, hair removers to remove armpit hair, deodorant creams to prevent armpit odor, etc., or shaving creams. Examples include shaving cream that is applied to the skin, and various chemicals are added to the cream base depending on the purpose.

Purpose of the invention and its summary As a result of intensive research to develop a cream that is more effective against symptoms such as rough skin, rashes, sores, and dry skin, the present inventor has developed a cream composition using shiitake mushroom mycelium extract. The present inventors have completed the present invention by discovering that when the resulting cream composition is applied to the skin, the above-mentioned symptoms are significantly and quickly recovered.

That is, the cream composition according to the present invention is characterized in that a shiitake mushroom mycelium extract is blended into a cream base.

The cream composition according to the invention has been found to be particularly effective when applied to skin irritated by Trichophyton, such as athlete's foot.

Detailed Description of the Invention The shiitake mycelium extract blended into the cream composition is obtained by extracting various active ingredients from a solid medium containing shiitake mycelium obtained by growing Shiitake fungi on a solid medium based on Bacchus. Alternatively, it is an extract obtained by extraction with a mixed solvent of water and an organic solvent such as alcohol. This shiitake mushroom mycelium extract contains large amounts of various amino acids and vitamins.

Furthermore, it has been discovered that shiitake mushroom mycelium extract also contains lentinol, a compound with strong antibacterial activity, and this lentinol exhibits antibacterial activity against Trichophyton, for example. It is speculated that it provides quick recovery to skin damaged by athlete's foot, etc.

It has been confirmed that the shiitake mycelium extract contains extremely large amounts of nutritional components and medicinal components compared to the shiitake mushroom extract. For example, 2.07g of shiitake mushroom mycelium per 100g of mycelium.
Contains threonine, an essential amino acid, whereas shiitake mushroom fruiting bodies only contain 0.8g per 100g of fruiting bodies.
It only contains threonine.

This Shiitake fungus mycelium extract is produced by inoculating Shiitake fungi into a solid medium based on Bacchus, then multiplying the mycelium, unraveling the mycelium-containing solid medium, and adding water and the necessary ingredients. After adding enzymes such as cellulase, protease or glucosidase as appropriate, the solid medium is crushed and crushed to extract the active ingredients, and then heated to a temperature of up to 95°C to deactivate the enzymes and sterilize the bacteria. You can get it by twisting it.

The time to unravel the solid medium containing mycelium is preferably when the mycelium has grown sufficiently in the solid medium and immediately before or immediately after the fruiting body appears.

The shiitake mycelium extract is added to the cream base, and a wide variety of conventionally known cream bases can be used. The cream base may be oil type, W/O type, 0/W type, or oil-free type. As the oily component, beeswax, cacao butter, stearic acid, lanolin, olive oil, camellia oil, solid paraffin, vaseline, liquid paraffin, silicone oil, synthetic ester oil, synthetic polyether oil, etc. are used. Water-based components include moisturizers such as glycerin, propylene glycol, sorbitol, and polyethylene glycol, mucilage substances such as quince seed gum, tragacanth gum, sodium alginate, sodium carboxymethylcellulose, and polyvinyl alcohol, alcohols such as ethyl alcohol, and isopropanol, and water. is used.

In addition, if necessary, ingredients normally used in cream bases, such as fragrances,
Preservatives (such as benzalkonium chloride), antioxidants, dyes, etc. can be added.

The cream composition to which the shiitake mycelium extract is added can be a wide variety of cream types, such as emollient creams, pine surge creams, cleansing creams, makeup creams, base creams, pre-makeup creams, sunscreen creams, deodorant creams, etc. .

The cream composition according to the present invention can be produced by a conventional method for producing a cream composition, except that the shiitake mycelium extract is added and contained in the cream base.

In addition, when adding the shiitake mushroom mycelium extract to the cream base, the shiitake mushroom mycelium extract may be used as a solution as an aqueous phase, or in some cases, an excipient may be added to this extract to form a powder. This powdered shiitake mycelium extract may be added to a cream base together with water or an organic solvent.

EXAMPLES Hereinafter, the present invention will be explained in detail with reference to Examples, but the present invention is not limited to these Examples.
