5results about How to "Transparent appearance" patented technology

The present invention discloses a rice Wx mutant protein, a mutant gene and its application, and also discloses a breeding method for creating quality-improved rice with transparent appearance and appropriately reduced amylose content by gene editing. The present invention uses gene editing technology for the first time to Wx By editing the gene with a single base, and through the screening of the offspring, new materials with T-DNA removed, transparent appearance, appropriately reduced amylose content, improved quality, and stable inheritance can be obtained in the T2 generation. Compared with breeding such as chemical mutagenesis and hybridization, gene editing directed improvement molecular breeding technology has the advantages of rapidity, accuracy, and efficiency. Combined with gene function marker genotype selection, or directly using other mature rice varieties as background materials for transformation and obtaining corresponding materials, it will greatly improve breeding efficiency and greatly accelerate the breeding process.

The invention provides a reverse micelle for extracting capsaicin and a preparation method thereof, and the preparation method comprises the following steps: S1, adding Span 20 and Span 80 into normal hexane, and carrying out ultrasonic treatment to obtain a solution A; s2, a NaCl solution is added into the liquid A obtained in the step S1 under the condition of oscillation stirring, a solution B is prepared, the solution B is centrifuged, and supernate is the reverse micelle solution used for extracting capsaicin. The method disclosed by the invention has the beneficial effects that the reverse micelle solution with transparent appearance and stable property can be prepared, and the separation of capsaicin is realized by utilizing reverse micelle extraction.

This invention provides a method for preparing 1,2-propanediol and its application. The method includes: step (1): in the presence of an acidic catalyst and water, ring-opening of a first portion of propylene oxide to obtain an acid-catalyzed reaction solution containing 1,2-propanediol; step (2): in the presence of an alkaline catalyst and water, ring-opening of a second portion of propylene oxide to obtain an alkaline-catalyzed reaction solution containing 1,2-propanediol; step (3): mixing the obtained acid-catalyzed reaction solution and the alkaline-catalyzed reaction solution for a neutralization reaction to obtain a mixture containing 1,2-propanediol; wherein, the molar ratio of the first portion of propylene oxide to water in step (1) and the molar ratio of the second portion of propylene oxide to water in step (1) are each independently 1:1-5; using the method of this invention to prepare 1,2-propanediol requires only a lower water ratio to obtain a higher propylene oxide conversion rate and 1,2-propanediol content, and the wastewater volume is lower and the color is colorless after the reaction.

The present invention relates to the field of washing and care technology, and in particular to a two-in-one washing and unloading composition and its application and products. The present invention provides a two-in-one washing and unloading composition with excellent foaming and makeup removal power, characterized in that, according to mass percentage, the composition comprises: 5-10% fatty acyl amino acid surfactant; 1-10% cocamidopropyl betaine; 1-10% sodium lauroylamphoacetate; 1-10% alkyl glycoside; 1-10% PEG-20 glyceryl triisostearate; 5-10% polyglycerol fatty acid ester nonionic surfactant; 1-5% propylene glycol fatty acid ester; water is supplemented to 100%. The components prepared by the present invention have a transparent product appearance and a neutral pH value. When cleaning, the skin is cleaner by removing sunscreen, makeup, grease, dust, etc.; and there is no stimulation at the same time. The emulsifier for makeup removal in the composition forms a self-assembled hierarchical emulsified micelle in a cleaning foaming surfactant (lauroyl sarcosine, cocamidopropyl betaine, decyl glucoside) system.

The invention relates to the technical field of production and manufacturing of automotive-grade varnish, and specifically to an automotive-grade ultra-long-lasting antibacterial varnish, a preparation method and an application thereof. The coating meets the technical requirements of automotive-grade interior coatings by adopting a compounded hydroxyl resin, nano-powder and a series of additives. Nano-hybrid inorganic antibacterial materials and ammonium salt organic antibacterial agents are added, and the organic and inorganic antibacterial agents can act synergistically in the coating. The varnish coating meets the performance requirements of automotive-grade coatings and has an extremely high antibacterial rate and an extremely low antibacterial rate aging attenuation. The varnish coating has an excellent antibacterial effect before aging, and the killing rates of Escherichia coli, Staphylococcus aureus and Candida albicans are greater than 99.99%. After 20 cycles of high and low temperature aging and more than 800 hours of light aging, the antibacterial effect has no obvious attenuation, and the killing rates of Escherichia coli, Staphylococcus aureus and Candida albicans are greater than 99.99%.
