Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention relates to
The present invention relates to cosmetics and bath preparations comprising a dry powder, an extract or a freeze-dried powder of the extract.

[Conventional technology and its problems]

The seaweed rhinoceros, belonging to the red algae, is a warm-sea marine algae that proliferates near the low tide line.Today, it is used in very few applications as a sizing agent for textiles and only a small part as food. Absent.

The present inventors have conducted intensive studies on a new use of the red rhinoceros rhinoceros, and surprisingly found that the extract of rhododendron rhinoceros has excellent affinity for human skin and excellent moisturizing and emollient effects. And found that it moisturizes the skin and maintains healthy and shiny skin. The effect of this extract extends not only to human skin but also to the head hair, has a remarkable effect on repairing damaged hair such as split ends and cut hairs. It has also been found that effects such as heat retention, warming, and beauty can be obtained, and that these effects can be obtained not only from the extract of P. chinensis, but also to the dry powder of P. chinensis and the freeze-dried powder of the extract, leading to the completion of the present invention. Was.

[Means for solving the problem]

That is, the present invention provides a dried powder of
The present invention relates to a cosmetic and a bath containing an extract or a freeze-dried powder of the extract.

[Operation and Examples]

It is not clear why the dried powder, extract or freeze-dried powder of P. auricularis exerts the above-mentioned effects, and it is presumed that components specific to P. auricularis effectively act. This is because, as described below, the carrageenan, a polysaccharide collected from red algae, differs in physical and chemical properties such as the dry powder and extract used in the present invention, and the effect of the present invention, namely, This is because they have no property.

What is blended in the present invention is a dry powder, an extract or a lyophilized powder of the extract.

After collecting from the sea, foreign matter is removed and the whole algae or a part thereof is used.

The dried powder can be obtained by drying the sunflower or freeze-drying and then grinding. When applied in the form of a powder, the average particle size is suitably about 3 to 300 μm.

The extract is obtained by chopping or pulverizing the dried rhinoceros beetle and immersing it in an extraction solvent. Examples of the extraction solvent include water; lower alcohols such as methanol and ethanol; glycols such as ethylene glycol, propylene glycol, glycerin and 1.3-butylene glycol; oleyl alcohol, stearyl alcohol;
Higher alcohols such as octyldodecanol; ketones such as acetone; esters such as ethyl acetate; n-hexane, iso-hexane, dichloromethane, cyclohexane and derivatives thereof, and hydrocarbon solvents such as benzene, toluene and xylene. One or more kinds may be mentioned. Among them, water or a water-soluble solvent is preferable, and one or more mixed solvents of water, ethanol, glycerin and 1,3-butylene glycol are particularly preferable. The extraction time varies depending on the type of the solvent, the extraction temperature and the like, but is usually 10 minutes or more, preferably 30 minutes to 1 hour. The extraction temperature varies depending on the type of the solvent, but is suitably 0 ° C or higher, usually 40 to 60 ° C. The obtained extract may be concentrated under reduced pressure to adjust the concentration. In addition, a powder obtained by freeze-drying and then pulverizing this extract can also be used.

The dried extract used in the present invention is in the form of a white powder, and is soluble in ethanol and isopropanol. This aqueous solution exhibits thixotropic properties.

Such dry powders, extracts and lyophilized powders thereof,
As described above, it has an excellent moisturizing effect and an emollient effect on human skin, imparts luster to the skin, and is well adapted to the skin, and can provide cosmetics having these effects.

The cosmetics of the present invention can be prepared in the form of, for example, creams, emulsions, lotions, facial cleansers, basic cosmetics such as packs, lipsticks, makeup cosmetics such as foundations, body soaps, toiletries such as soaps, and the like. It is also effective for repairing and restoring split hair and cut hair to the hair, and also for protecting the hair.For example, hair tonic, hair liquid, hair set lotion, hair blowing agent, hair cream, hair pack,
Hair products such as hair coats, shampoos, rinses,
It can also be in the form of a hair care product such as a hair toiletries product such as a hair treatment. The amount of the dry powder or the extract (solid content 0.7% by weight) and the freeze-dried powder thereof in 100 parts (parts by weight, hereinafter the same) of the cosmetic is usually about 0.1 to 90 parts, preferably 5 parts by weight. It may be up to 50 parts. As other ingredients of cosmetics,
What is usually mix | blended with each cosmetics can be used.

Further, the dry powder, the extract, and the freeze-dried powder thereof are excellent in a warming effect and a heat retaining effect in addition to the effects described in the cosmetic by being poured into hot water at the time of bathing, and provide an excellent bath agent. can do.

The mixing ratio of the dry powder or extract (solid content 0.7% by weight) and the freeze-dried powder thereof in the bath preparation of the present invention is about 1 to 90 parts, preferably 20 to 6 parts in 100 parts of the bath preparation.
What is necessary is just 0 parts. As the other components of the bath, those usually blended in the bath can be used. The bath agent of the present invention thus adjusted may be added in an amount of usually about 5 to 25 g per 200 parts of hot water.

Next, the present invention will be described based on examples, but the present invention is not limited to only these examples.
