The invention discloses an oil-control pore-shrinking composition containing lactobionic acid. The oil-control pore-shrinking composition comprises the following components in percentage by weight: 0.0001-20% of lactobionic acid, 0.0001-30% of a flos spiranthis sativae extract, 0.0001-20% of nicotinamide and 0.0001-20% of carnitine. The oil-control pore-shrinking composition disclosed by the invention can intelligently identify aged keratinocytes, remove aged dead cells and promote the regeneration of the keratinocytes. The oil-control pore-shrinking composition can remove dirt in pores, helpthe proliferation of hyaluronic acid and collagen in a dermis layer, increase the water content of skin, visually shrink the pores and enable the whole skin to become compact and elastic. The flos spiranthis sativae extract can effectively shrink coarse pores, inhibit abnormal oil production of hair follicles and inhibit bacterial reproduction and prevent acnes. Moreover, the oil-control pore-shrinking composition is mild and non-irritant, can serve as an oil-control pore-shrinking active component and is applied to various cosmetics.

The invention discloses a preparation method of (2S,3S)-2,3-butanediol, and belongs to the technical field of biochemistry. The preparation method comprises the following steps of: stirring and mixingsolution containing ketoreductase with buffer solution to obtain mixed solution; in the stirring process, adding nicotinamide adenine dinucleotide, isopropanol and 2,3-butanedione into the mixed solution to perform closed reaction, so that reaction solution is obtained; carrying out reduced pressure suction filtration and rotary evaporation treatment on the reaction solution to obtain extractingsolution; and carrying out rectification separation on the extracting solution to obtain the (2S,3S)-2,3-butanediol. Meanwhile, the invention provides an amino acid sequence of the ketoreductase for catalyzing 2,3-butanedione to generate the (2S,3S)-2,3-butanediol. The invention further provides a nucleotide sequence for coding the ketoreductase. The preparation method is simple in synthetic routeand high in efficiency; 2,3-butanedione is reduced into (2S,3S)-2,3-butanediol by selecting the ketoreductase in an isopropanol system; the conversion rate of 2,3-butanedione can reach up to 95%; andin addition, the chiral purity of the prepared (2S,3S)-2,3-butanediol product can also reach 98%.

The invention relates to an acne-removing conditioner, an acne-removing mask composition and a preparation method of the acne-removing conditioner and the acne-removing mask composition. The acne-removing conditioner is prepared from the following components of 10 to 20 parts of calamine, 0.1 to 2 parts of coated salicylic acid, 0.001 to 0.01 part of oligopeptide-1, 0.001 to 0.01 part of palmitoyl tripeptide-8 and 0.1 to 10 parts of nicotinamide. The acne-removing mask composition is prepared from the components in parts by weight: 50 to 95 parts of aqueous matrix and 5 to 25 parts of oil gel, wherein the water aqueous matrix comprises the acne-removing conditioner and a gel thickening agent; the oil gel comprises grease and a cross-linking agent. According to the acne-removing conditioner, the acne-removing mask composition and the preparation method of the acne-removing conditioner and the acne-removing mask composition, the aqueous matrix and the oil gel are separately stored and are mixed during use, and then the mixture is smeared on the face for use, so that a formed film can be stripped, and a product has the advantages of good skin fitting property, no sensitization and irritation and convenience in use; the preparation method of the acne-removing mask composition is simple and easy to implement, raw materials are easy to obtain, the corresponding aqueous matrix and the oil gel can be separately stored and mixed during use, and the acne-removing mask composition is suitable for large-scale production.

The invention discloses an acne treatment gel with an acne treatment composition. The acne treatment gel consists of the following raw materials in parts by weight: 35-45 parts of a grease expelling mixture, 15-25 parts of nicotinamide, 1-10 parts of ACSD (coupled salicylic acid), 10-20 parts of a traditional Chinese medicine active mixture, 10-20 parts of mint alcohol lactate and 1-6 parts of dipotassium glycyrrhizinate. Epidermis micro-ecological conditions and pH values can be regulated, and most acne-resulted harmful florae are not easy to multiply or grow; sebaceous gland activity can be rapidly regulated, and water-oil balance of skin can be recovered; inflammation can be prevented and eliminated, and discomfort symptoms can be relieved.

The invention discloses a facial mask added with peony extract and a preparation method thereof. The facial mask is prepared from the following raw materials: peony extract, nicotinamide, inositol, oil-soluble vitamin E, an emulsifier, chrysanthellum indicum, honeysuckle flower, pseudo-ginseng root, eucommia bark, glycerin, low-molecular hyaluronic acid, an antibacterial agent and deionized water. According to the invention, substances like a peony flower stock solution, peony seed oil, chrysanthellum indicum, inositol, low-molecular hyaluronic acid, honeysuckle flower and pseudo-ginseng root are mixed to form a compound, so the whitening and skin-tendering facial mask suitable for modern women is formed; and the facial mask can effectively improve the antioxidant capacity of skin, injects sufficient moisture into skin, prevents moisture in the stratum corneum of skin from evaporating, enables loaded plant essence to be easily absorbed, maintains the face to be moist, has good whitening and repairing effects, can effectively remove free radicals in skin, prevents accelerated aging of facial skin, reduces facial wrinkles and has ideal antioxidation and skin aging delaying effects.
