Abstract

PURPOSE:To provide a cosmetic containing a specific carbohydrate and vitamin E and having improved stability to temperature, light, etc., without lowering the smoothness and moisturizing feeling to the skin. CONSTITUTION:The objective cosmetic contains (A) a carbohydrate selected from a monosaccharide such as glucose, xylose, etc., a disaccharide such as sucrose, maltose, etc., and a trisaccharide such as raffinose, stachyose, etc., excluding sugar alcohols and (B) vitamin E or its derivative.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides one or more carbohydrates selected from the group consisting of monosaccharides, trisaccharides, and trisaccharides excluding sugar alcohols, and vitamin E.
and one or more of its derivatives.By adding vitamin E and/or its derivatives to a cosmetic containing carbohydrates as a cosmetic component, To provide a novel cosmetic that is stabilized without impairing the smoothness and moist feeling to the skin, which are characteristics of cosmetics containing carbohydrates.

[Prior art 1] Carbohydrates, along with proteins and lipids, are major nutritional sources, and are particularly important energy sources for living organisms. Carbohydrates such as saccharides have traditionally been regarded as important only as energy sources or as skeletal structural substances for animals and plants in pure form, such as cellulose and chitin, but due to recent remarkable advances in biochemistry,
It has been discovered that it binds to proteins and lipids and has an important relationship with biological phenomena. As a raw material for cosmetics, this carbohydrate is used as a moisturizing agent, softener, antifreeze agent, and thickening agent because it gives a smooth and moist feel to the skin, and is also used in various fragrances. It is also used as a solvent and fragrance preservative.

However, despite these effects, carbohydrates have poor stability against temperature and light, and compositions containing carbohydrates have generally been required to be stored in a cool place and protected from light.

However, such preventive measures cannot be thoroughly controlled once the product reaches the consumer, and in countries like Japan, where there is a large temperature difference,
In countries where sunlight is exposed for long periods of time, compositions containing carbohydrates can cause problems such as discoloration and gel softening, which is a major problem, especially for products such as cosmetics where deterioration of appearance is a fatal drawback. was.

[Problems to be solved by the invention] In view of the above-mentioned circumstances, the inventors have conducted extensive research to obtain cosmetics containing carbohydrates that are stable against temperature and light. It has been discovered that the above-mentioned problems can be solved by incorporating vitamin E and/or its derivatives, and the present invention has been completed.

[Failure to solve the problem]

That is, the present invention provides a method for removing sugar alcohols (one or more carbohydrates selected from the group consisting of monosaccharides, trisaccharides, and trisaccharides),
This cosmetic is characterized by containing one or more kinds of vitamin E and its derivatives.

Examples of carbohydrates used in the present invention include monosaccharides such as glucose, xylose, and fructose, trisaccharides such as sucrose, maltose, and lactose, and trisaccharides such as raffinose. More specifically, monosaccharides include D-glyceraldehyde, D-erythrose, D-threose,
D-ribose D-arabinose, D-xylose, D-
D-fuldose series sugars such as lyxose, D-allose, D-aldrose, D-glucose, D-mannose, D-gulose, D-idose, D-galactose, D-grose, dihydroxyacetone, D-erythrulose, D - D-ketose series sugars such as ribulose, D-xylose, D-glucose, D-fructose, D-sorbose, D-tagatose, α-D-glupyranose,

-Iduronic acid and the like. Furthermore, D-glucosamine,
Also mentioned are amino acids such as D-galactosamine. Examples of trisaccharides include sucrose, lactose, trehalose, maltose, hepta-robiose, etc., and examples of trisaccharides include raffinose, stachyose, etc. One or more types are arbitrarily selected from these.

The blending amount is preferably 0.01 to 10% by weight. If it is less than 0.01% by weight, the skin may not feel smooth or moist, and if it exceeds 10% by weight, it may feel sticky when used. More preferably, it is 0.05 to 8% by weight.

Vitamin E used in the present invention is a fat-soluble vitamin that is abundantly contained in vegetable oil and is called tocopherol. α, β
There are four types: , γ, and δ. Furthermore, vitamin E acetate etc. which are acetylated with these derivatives may also be used. One or more types are arbitrarily selected from these.

The blending amount is preferably 0.001 to 2% by weight. 0.001
Less than % by weight may have no effect on stability;
If it exceeds 2% by weight, there may be a problem that it causes stickiness. More preferably, it is 0.005 to 1% by weight.

In addition to the above-mentioned essential ingredients, the cosmetics of the present invention may optionally contain oil, surfactants, humectants, lower alcohols, thickeners, fragrances, antioxidants, and chelating agents, depending on the type of cosmetic. , pigments, preservatives, and other ingredients commonly used in cosmetics can be blended.
