Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a powdered biological preparation prepared by freeze-drying live bacteria.
To provide a novel cosmetic which is characterized by being blended into a powdered cosmetic base and imparts a smooth and moist feeling to the skin, and shine and finish effect to the hair. It is something.

[Conventional technology]

Freeze-drying is often used to produce and preserve various enzyme proteins, including Lysozyme. Generally, biological products include vaccines, antitoxins, therapeutic blood 7n, diagnostic antigens, and blood products. Among these, many of those consisting of live bacteria, live viruses, and active substances have unstable properties, but it is extremely important to maintain their efficacy at a certain level due to their intended use. From this point of view, there is a method of utilizing freeze-drying for the purpose of protecting biological preparations from various changes and maintaining a constant potency for as long as possible.

On the other hand, lactic acid bacteria, chlorella bacteria, bifidobacteria, Koji bacteria,
There are many examples in the food industry where live bacteria such as yeast are added, but there are no examples in the cosmetics industry where live bacteria that are effective for humans are used.

[Problem that the invention seeks to solve]

In view of the above-mentioned circumstances, the present inventors have conducted extensive research and found that if freeze-drying is used in cosmetics, live bacteria can be effectively incorporated into cosmetics, and active cosmetics can be obtained. Focusing on dry, powdered biological preparations, the dried, flaked, or freeze-dried bacteria instantly regains activity, and when applied to the skin, it remains smooth and moist against skin RF. The present inventors have discovered that the present invention can be used to improve the hair's texture, give shine, and give the hair a finish effect.

[Means to solve the problem Toyonaka transfer] In other words,
The present invention is a cosmetic containing one or more powdered biological preparations obtained by freeze-drying live bacteria.

The live bacteria used in the present invention are preferably those that are harmless to the human body and have high skin safety, and are those that have been conventionally used in microbial industries such as fermented food and drink products.

For example, examples of live bacteria found in fermented foods include:
The Koji fungus Asbergillus oryzae (As

Furthermore, as viable bacteria for industrial products, Clostridium acetobutylic, a butanol bacterium for acetone and butanol, is used.

One or more types of these viable bacteria are arbitrarily selected.

The blending amount is generally 0.0001 to 10% by weight. If it is less than 0.0001% by weight, the effects of the present invention cannot be exhibited, and if it exceeds 10% by weight, usability will deteriorate.

During freezing, whether or not intracellular water freezes depends on the conditions (although the main parameters are freezing rate, cell size, and cell membrane permeability to water. In general, intracellular freezing It is fatal to living cells.However, in relatively small cells such as bacteria, extracellular freezing tends to occur as a practical matter.In this case, the mechanical destruction of ice crystals and 10% water Even if it is cooled to -80℃, it does not freeze → body → body ÷. As the drying progresses and the antifreeze water is lost, bacteria rapidly begin to die.

When freeze-drying, pay attention to the above points and create conditions for each bacteria that will not kill them, if necessary.
Dry, moisture-free cosmetic bases can be mixed. The cosmetic base is preferably one with a low grade or lower that dissolves or decomposes in water or cosmetics added at the time of use.
