977 results about "Keratin" patented technology

Keratin (/ˈkɛrətɪn/) is one of a family of fibrous structural proteins. It is the key structural material making up hair, nails, feathers, horns, claws, hooves, and the outer layer of skin. Keratin is also the protein that protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. The only other biological matter known to approximate the toughness of keratinized tissue is chitin.

Hair nourishing and damage repairing shampoo

The invention discloses hair nourishing and damage repairing shampoo. The hair nourishing and damage repairing shampoo comprises the components in percentage by weight: 0.5-5.0 percent of a medicinal plant extract, 0.1-3.0 percent of keratin, 8-12 percent of a surfactant, 4-8 percent of a conditioner, 0.3-1.5 percent of an acid-base regulator, 1-2 percent of a thickener, 0.5-2.0 percent of a pearlescing agent, 0.1-0.4 percent of salt and 68-80 percent of deionized water, wherein the medicinal plant extract is obtained by crushing medicinal plants, carrying out extraction or circulating extraction on the crushed medicinal plants with the water or ethyl alcohol as an extractant under the room temperature and ordinary pressure to obtain an extract solution, and concentrating the extract solution; the medicinal plant extract comprises the components in parts by weight: 10-25 parts of ligusticum wallichii, 15-30 parts of eclipta alba, 10-25 parts of astragalus membranaceus and 15-30 parts of cacumen biotae; the molecular weight of the keratin is no more than 40000 Daltons. With the adoption of the hair nourishing and damage repairing shampoo, damaged hairs can be relatively rapidly and effectively repaired, the uncooling feeling in the using process and after the use is avoided, a formula is also simplified, and the cost is lowered.

Preparation method of golden nanoclusters emitting red fluorescence

The invention discloses a preparation method of golden nanoclusters emitting red fluorescence. The method is characterized by comprising the following steps: separately preparing a chloroauric acid solution and a keratin solution, slowly adding the chloroauric acid solution into the keratin solution, and then fully stirring the mixture to uniformly mixing the solutions to obtain a faint yellow solution; regulating the pH value of the solution to 8-12; placing the solution at 25-60 DEG C to incubate to obtain a brown golden nanocluster solution; and pouring the golden nanocluster solution intoa dialysis bag to be dialyzed, wherein the molecular weight cut-off is 3500Da, and then freezing and drying the mixture to obtain the golden nanocluster particles. By taking keratin as a stabilizer and a reducer and tetrachloroauric acid as a precursor to synthesize fluorescent golden clusters, the prepared golden nanoclusters emit red fluorescence, the maximum excitation wavelength is 520nm and the maximum emitting wavelength is 670nm. The keratin has rich sulfydryl, is good in stability, and meanwhile, has an effective reducing capacity.

Method for separating and extracting fibrillar structure body in natural keratin fiber with reducing solvent

The invention provides a method for taking reducing solvent to separate and extract fibrillar structural body and keratin solution in natural keratin fiber, and is characterized by comprising the concrete steps: the natural keratin fiber is sequentially processed by opening and scotching, decontaminating, washing and drying, cut into fiber sections having the length of 3-6mm, dipped into protein denaturation solution which contains the reducing solvent and can break hydrogen bond of protein and then stirred at the temperature of 50-90 DEG C; after the mixture is filtered by a screen mesh, the fibrillar structural body with the diameter of 2-4mum and filtrate can be obtained; the filtrate is separated to obtain the fibrillar structural body with the diameter of 0.2-0.4mum and centrifugal supernatant fluid, and then the obtained fibrillar structural body is washed and dried; after the centrifugal supernatant fluid is dialyzed and concentrated, the keratin aqueous solution can be prepared. The invention can be used for preparing anisotropic fibrillar structural body and keratin solution, and has the advantages of simple method, high productive rate, low energy consumption and seldom environmental pollution.
