    摘要: PROBLEM TO BE SOLVED: To obtain a new compound useful as an intermediate for two-chain two-hydrophilic group-containing anionic surfactants which are high-performance surfactants. SOLUTION: This compound is represented by formula I [(n)+1] is 8-20; (m) is 2-6}, preferably a compound represented by formula II. The above compound represented by formula I is preferably obtained by acylating a known amino compound and specifically dissolving an amino compound represented by formula III and sodium hydroxide in water/diethyl ether (1:1), then dropping lauroyl chloride thereto under stirring at room temperature, stirring the resultant mixture for 1 h and subsequently regulating the pH with hydrochloric acid. The compound represented by formula II is preferably obtained by hydrolyzing the compound represented by formula I with an alkali and then regulating the pH to an acidic one (pH 1).

    摘要: PURPOSE:To obtain a cosmetic for hair having high safety and stability and giving excellent smoothing effect, luster improving effect and wet effect, etc., to hair containing a modified transglutaminase(TGase) modified with a water-soluble substance. CONSTITUTION:Modified TGase modified with a water-soluble substance such as polyhydric alcohol, e.g. polyethylene glycol or glycerin, saccharides such as glucose, sucrose or polysaccharides e.g. alginic acid or CMC is contained in the objective cosmetic in an amount of 0.00001-1.0wt.% based on total weight of the cosmetic. Preferably 0.2-50 pts.wt. water-soluble substance is used to 1 pts. wt. TGase. The TGase densifies surface structure of the hair and water- retention activity of the hair is enhanced, then a flexibility and elasticity are imparted.

    摘要: PURPOSE:To obtain a cosmetic having excellent heat resistance, light resistance and stability to the skin, containing gold dyed protein prepared by dyeing protein with gold colloid. CONSTITUTION:Protein is added to water dispersion of gold colloid while stirring, aged for about tens minutes, filtered, washed with water and dried to give gold dyed protein. In the operation, protein is mixed with 0.1-2wt.% gold colloid. 0.01-50wt.% of the gold dyed protein is properly blended with components useful for ordinary cosmetic, such as humectant, water-soluble polymer, surfactant, water, oil, wax, perfume, colorant, antiseptic, antioxidant and germicide and prepared to give the objective substance. The substance is processed into a form such as cream, lotion, powder or spray and applicable to a wide range of cosmetic such as make-up cosmetic, hair cosmetic and face washing cosmetic.

    摘要: PURPOSE:To obtain a cosmetic, excellent in coloring properties, preservation stability and skin stability, and useful as cream, eye shadow, lipstick, nail color, skin cream, etc., by dyeing silk fibroin powder with gold colloid and blending the resultant gold-dyed silk fibroin powder with other ingredients. CONSTITUTION:A cosmetic obtained by treating an aqueous solution of a gold salt, such as chloroauric acid, as a raw material with a water-soluble reducing agent, such as sodium borohydride, adding silk fibroin powder into the resultant aqueous dispersion of gold colloid which is a gold hydrosol while stirring the dispersion and blending the prepared gold-dyed silk fibroin powder with other ingredients. The amount of the blended gold-dyed fibroin powder is preferably about 0.01-50wt.% based on 100wt.% cosmetic. The aforementioned cosmetic is good in tint and coloring properties and excellent in heat, light resistance, etc., preservation stability with high skin safety and remarkable action and effects thereof without skin irritancy, etc.

    摘要: PURPOSE:To produce a modified protease exhibiting suppressed cutaneous sensitization and antigenicity and having excellent stability and high activity by reacting a protease with a polysaccharide having bonded triazine ring and produced by reacting a polysaccharide with cyanuryl chloride. CONSTITUTION:A polysaccharide bonded with triazine ring is synthesized by reacting a polysaccharide (preferably dextrin, pullulan, etc.) with cyanuryl chloride preferably at pH8-11. The amount of triazine ring in the bonded polysaccharide is preferably >=3X10 mol/l. The bonded polysaccharide is made to react with a protease originated preferably from microorganism (especially from genus Bacillus) at a weight ratio of >=3/1. The obtained modified protease can be purified by ultrafiltration. gel-filtration, liquid chromatography, etc.

    摘要: PURPOSE:To provide a skin cosmetic containing a chitosan having a specific average molecular weight, an acidic mucopolysaccharide and its salt, having excellent age-preventing effect and skin-beautifying effect and giving excellent appearance such as skin texture and transparency. CONSTITUTION:The objective skin cosmetic contains at least one kind of component selected from (A) a chitosan having an average molecular weight of 1,000-10,000 (soluble in water even in the absence of acid and produced by the chemical treatment or enzymatic decomposition of a chitosan produced by the deacetylation of chitin) and (B) an acidic mucopolysaccharide (e.g., hyaluronic acid, dermatan sulfate or chondroitin 4-sulfate) or its salt (preferably having a molecular weight of 1.000-100,000). It exhibits skin aging-preventive effect such as chapped skin ameliorating effect, cuticle improving effect and humectant effect.

    摘要: PURPOSE:To obtain a cosmetic having excellent stability with day and adaptability, comprising modified superoxide dismutase prepared by bonding a polyalkylene glycol to superoxide dismutase of copper or zinc type and a water- soluble polyhydric alcohol as essential components. CONSTITUTION:A skin cosmetic suitable as skin lotion, cosmetic milky lotion or cosmetic cream, comprising modified superoxide dismutase (preferably 0.00001-1pt.wt. calculated as enzyme amount) prepared by bonding a polyalkylene glycol to superoxide dismutase of copper or zinc type (one obtained from plant leaf or blood cell, liver or placenta of animal) and a water-soluble polyhydric alcohol (preferably 0.5-50wt.% based on total amount) as essential components. Since a large amount of superoxide occurring in exposure of the skin to ultraviolet rays or wound is disproportionated and differentiated by using the cosmetic, aging and drying of the skin is prevented.
