The present invention relates to S-(β-
Hydroxy-γ-trimethylammoniopropyl)keratein. (In the formula, Ker represents a keratein main chain with a molecular weight of 10,000 to 100,000, and X represents a halogen.) Keratein is a keratein that has a sulfhydryl group (-SH ) is the cleaved form. Keratin is a general term for fibrous proteins that are distributed in the epidermis of higher animals and perform biological protection functions, such as wool, feathers,
Hair, nails, horns, etc. There are 18 amino acids that make up keratin (ararin, arginine, aspartic acid, cystine, glutamic acid, glycine,
histidine, isoleucine, leucine, lysine,
methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine), and its characteristics include a high cystine content,
On average, there is one disulfide bond (-S-S-) per 10 to 20 amino acid residues, forming a cross-linked structure. In order to use keratin industrially, it is first necessary to dissolve it in some kind of solvent, such as water, and to do so, the crosslinked disulfide bonds must be cleaved. Methods of cleavage include reduction and oxidation, and upon reduction, the disulfide bond becomes a sulfhydryl group (-SH) and the product is called keratein (Ker-SH). On the other hand, by oxidation, the disulfide bond becomes a sulfonic acid group (-SO 3 H), and the product is keratose (Ker-
SO 3 H). The linear protein obtained in this way should essentially be soluble in water, but it is poorly soluble in water and organic polar solvents due to hydrogen bonds, ionic bonds, hydrophobic bonds, etc. between proteins. Even if it is dissolved, only an extremely dilute solution can be obtained. As a result of extensive studies, the present inventors found that the sulfhydryl group in keratein was replaced by an S-β-hydroxy-γ-trimethylammoniopropyl group.

プロピル)ケラテインである事がわかる。It was discovered that a keratein derivative that is easily soluble in water and a mixed solvent of water and a hydrophilic organic solvent can be obtained by changing the formula to [Formula], and the present invention was achieved based on this finding. That is, the present invention is based on the general formula (In the formula, Ker represents a keratein main chain with a molecular weight of 10,000 to 100,000, and X represents a halogen.) . Note that keratein in the present invention does not refer to oligopeptides obtained by hydrolyzing keratin, which generally have a molecular weight of several thousand or less, but refers to oligopeptides with a molecular weight of 10,000 to 100,000 obtained by cleavage of the disulfide bonds of keratin, and usually The amount obtained from keratin is 20,000~
Many are priced at 50,000. S-(β-hydroxy-γ-trimethylammoniopropyl)keratein is produced, for example, by the following mechanism. The raw material, keratin, is made from natural wool, feathers, hair, etc., which has been washed to remove impurities and then used as is. The first step of the keratin reduction reaction can be carried out by a conventionally known method. That is, water or a mixed solvent of water and a hydrophilic organic solvent is used as the solvent. Examples of such hydrophilic organic solvents include methanol, ethanol, n-propanol, acetone,
Examples include methyl ethyl ketone, dioxane, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, and hexamethylphosphoric triamide. In addition, as a reducing agent, for example, 2
-Mercaptoethanol, thioglycolic acid, tri-n-butylphosphine, triphenylphosphine, ascorbic acid, sodium bisulfite, sodium sulfite, etc. are used. Although room temperature is usually sufficient for the reaction temperature, the reduction time can be shortened by heating if necessary. The reaction time usually takes 2 to 3 hours or more. Furthermore, regarding the pH of the reaction system, the reduction reaction is generally carried out within the range of 6 to 11. Next, in the second step of the keratein modification reaction, the reagent added to keratein includes, for example, glycidyltrimethylammonium chloride as shown in formula (2). The addition reaction is carried out by adding glycidyltrimethylammonium chloride in an amount equivalent to the sulfhydryl group produced by the reduction to the reduction reaction medium after the completion of the reduction reaction. Any reaction temperature can be selected from room temperature to 90℃, but
The addition reaction is accelerated as the temperature increases. As the addition reaction progresses, S-(β-hydroxy-γ-trimethylammoniopropyl)keratein dissolves into the reaction medium, and the final insoluble portion becomes 30% or less based on the starting keratin. The insoluble portion is removed by means such as filtration or centrifugation, and S-(β-hydroxy-
A solution of γ-trimethylammoniopropyl)keratein is obtained. The solution of S-(β-hydroxy-γ-trimethylammoniopropyl)keratein thus obtained can be used as a solution after removing low-molecular impurities such as reducing agents by ultrafiltration or dialysis. It is possible, but S
-(β-Hydroxy-γ-trimethylammoniopropyl)keratein is more convenient to collect as a solid in terms of utilization and storage and transportation. Although the S-(β-hydroxy-γ-trimethylammoniopropyl)keratein of the present invention has a high molecular weight, it has extremely excellent solubility in water and a mixed solvent of water and a hydrophilic organic solvent. A uniform transparent film can be formed from these solvents, and by utilizing this property, it can be dissolved in a mixed solvent of water and ethanol and used as a setting lotion for hair. Next, the present invention will be explained in more detail with reference to Examples. Example 10g of wool fiber added with 0.02M Tris buffer
After immersing in 700 g of 50% n-propanol aqueous solution and adding 4 ml of tri-n-butylphosphine as a reducing agent, the pH was adjusted to 8.0 with 1N hydrochloric acid, and the reduction reaction was carried out at room temperature for 24 hours under a nitrogen stream. Let's do it. Next, add glycidyltrimethylammonium chloride to the reaction system.
When 1.5 g is added and stirred at 70°C for 5 hours, about 85% of the wool fibers are solubilized in the reaction solution. Insoluble portions were removed by filtration, and the resulting solution was subjected to ultrafiltration (using a membrane with a molecular weight cutoff of 1000) to remove low-molecular impurities such as reducing agents, and the entire system was concentrated to about 150 ml. By freeze-drying this, 8.1 g of solid powder was obtained. The molecular weight of the obtained powder solid was determined to be 39,000 by gel filtration method (using Sephadex G-75). In addition, the powder solid is 6N
Hydrolysis was carried out in hydrochloric acid at 110℃ for 24 hours, and amino acid analysis of the decomposed product (Hitachi Automatic Amino
Acid Analyzer Type KLA-5) was used to compare the amino acid analysis results of raw wool, and as shown in Table 1, the composition and content of amino acids other than cystine were almost the same. Although 5.5 moles of cystine in 100 moles of amino acids are found in the wool, none was found in the powdered solid, indicating that glycidyltrimethylammonium chloride was added thereto. Therefore, the molecular weight and amino acid analysis results of the obtained solid powder show that the main chain peptide bonds of the keratin protein have not undergone any changes such as hydrolysis, and the disulfide bonds have been cleaved to form β-hydroxy-γ-trimethylammoniopropyl. A group is added, that is, S
