Description

[Detailed description of the invention]

The present invention provides a novel cosmetic that is useful for skin and hair and contains an amino sugar sugar alcohol or a salt thereof. The cosmetics of the present invention provide smoothness and smoothness to the skin.
It provides moisture, keratin softening effect, and skin improvement effect, and for hair, it improves gloss, suppleness, and finish effect, and improves combability. Moreover, since the amino sugar sugar alcohol used in the present invention has moderate alkalinity, it can exhibit a PH buffering effect when combined with an acid in the system, or can exhibit an emulsifying effect when used as a neutralizer for higher fatty acids. It can also be used alone as an alkaline agent for cold waves. Traditionally, various raw materials extracted from natural products, such as proteins, polysaccharides, lipids, polymeric substances, and other extracts, have been used in cosmetics to provide effects and sensations that cannot be obtained from synthetic raw materials. There is. In addition, the simple substances and oligo substances (for example, amino acid peptides, etc.) constituting these substances are also treated as naturally-related raw materials. As a result of intensive research to obtain natural raw materials useful for skin and hair, the present inventors focused on amino sugar sugar alcohols, and cosmetics containing this substance are
Gives smoothness and moisture to the skin,
It has an excellent keratin softening effect and skin improvement effect, and also improves shine, suppleness, and finish of hair, improves combability, and is safe for the human body and stable over time. discover something,
The present invention has now been completed. That is, the present invention is a cosmetic containing one or more selected from the group consisting of amino sugar sugar alcohols and salts thereof. Although the amino sugar sugar alcohol used in the present invention can be obtained by synthesis, it is generally obtained mainly from structural polysaccharides that exist in nature, especially chitin, mucopolysaccharides, glycoproteins, and glycolipids that exist in insects and crustaceans. It is obtained by further reducing monosaccharide-type or oligosaccharide-type amino sugars obtained by hydrolyzing natural polymers such as, etc. with acids, enzymes, etc. Any reduction method may be used, and examples thereof include reduction with NaBH ₄ or high-pressure reduction using Raney nickel. In the present invention, among the above amino sugar sugar alcohols, it is preferable to use amino sugar sugar alcohols having 4 or more carbon sugars. Examples of the above-mentioned amino sugar sugar alcohols include erythrosaminitol, threosaminitol, xylosaminitol, arabinosaminitol, ribosaminitol, which has one amino group in one molecule;
Lixosaminitol, apiosaminitol, glucosaminitol, galactosaminitol, mannosaminitol, talosaminitol, allosaminitol, altrosaminitol, glossaminitol, idosaminitol, lactosaminitol, etc.
and 1. having two or more amino groups in one molecule.
2 diamino 1,2 dioxysorbitol, 1,2
diamino 1,2 dioxymannite and 1 amino 1
Deoxygalactosaminitol and the like can be mentioned. Furthermore, the amino sugar sugar alcohol used in the present invention also includes glycamine obtained by acting on a monosaccharide or oligosaccharide and then reducing it. The above-mentioned glycamines include erythrosamine, threosamine, arabinosamine, ribosamine, lyxosamine, apiosamine, glucamine, galactamine, mannaamine, talosamine, allosamine,
Examples include altrosamine, glosamine, idosamine, and lactosamine. When the amino sugar sugar alcohol of the present invention is used as a salt, an inorganic acid such as hydrochloric acid, sulfuric acid, phosphoric acid, oxyacid such as lactic acid, citric acid, tartaric acid, salicylic acid, acidic acid such as aspartic acid, glutamic acid, pyrrolidone carboxylic acid, etc. Amino acids, linear and branched fatty acids having 1 to 33 carbon atoms, organic acids such as glycyrrhizic acid, L-ascorbic acid, N-acyl amino acids, urocanic acid, thioglycolic acid, nicotinic acid, tannic acid, and carboxyvinyl polymers. An acidic substance such as an acidic polymeric substance is used. Among these acidic substances, if a suitable acid such as citric acid is used, the generated salt can exert a buffering effect in the system, and if neutralized with a suitable acid such as a fatty acid, it can have an emulsifying effect. It is possible to demonstrate this. The salt may be made into a salt in advance and added to the cosmetic of the present invention, or it may be generated during the manufacturing process, such as by adding it separately to the aqueous phase and oil phase and allowing them to react during emulsification. It's good to have a method. The blending amount of the amino sugar sugar alcohol or its salt is about 0.001 to 30% by weight based on the total amount of the cosmetic of the present invention. In addition to the above-mentioned essential ingredients, the cosmetics of the present invention may contain oil, water, surfactants, humectants, alcohol, thickeners, fragrances, antioxidants, chelating agents, pigments, and preservatives depending on the cosmetic type. Raw materials commonly used in cosmetics, such as, may be blended. The cosmetics of the present invention provide smoothness, moisture, keratin softening effects, and skin improvement effects to the skin, and improve gloss, suppleness, hair finish, and combability to the hair. do. Further, if necessary, it is also possible to impart a PH buffering effect, an emulsifying power improving effect, etc. in combination with the above-mentioned acids. Furthermore, when used as an alkaline agent for cold wave agents, the odor is much better than when conventional ammonia is used, and the effect is equally excellent. Next, the effects of the present invention will be explained in detail with reference to Examples and Comparative Examples. The present invention is not limited thereby.

Comparative Example 1 A lotion was obtained by the same manufacturing method as in Example 1, except that propylene glycol was used instead of D-glucosaminitol from Example 1. The evaporation rates of Example 1 and Comparative Example 1 were determined by the following test method. A 0.2 cc sample was placed on a 1 x 1 cm square paper, and the amount of water evaporated under conditions of 25°C and 50% relative humidity was measured, and the evaporation rate was obtained by dividing this by time.
