35results about How to "Inhibit photooxidation" patented technology

Disclosed is a composition for preventing or treating eye diseases. The composition for preventing or treating eye diseases contains S-allyl-L-cysteine, a pharmaceutically acceptable salt thereof, or a solvate or a hydrate thereof as an active ingredient, and may inhibit photo-oxidation. The composition for preventing or treating eye diseases inhibits the accumulation of A2E in retinal pigment epithelial cells and the oxidation of A2E, thereby remarkably preventing or treating eye diseases including age-related macular degeneration or degenerative retinal disorder.

The present invention is based on a surprising discovery of new packaging materials used to package substances, such as foods, preventing the photo-oxidation of entities found in these substances. Specifically, these new packaging materials include a mixture of polymer resins having novel and specific ratios of filler, preferably calcium carbonate, and titanium dioxide resulting in the material having unexpected properties.

The invention discloses a self-adhesive multilayer composite flexible decoration sheet preparation process, which specially comprises: adding rosin into ethanol, carrying out stirring dissolving, adding an epoxy resin, carrying out a stirring reaction, adding a RFE adhesive, and stirring and mixing at a normal temperature for 20-30 min to obtain a hydrophobic flame-retardant adhesive; and uniformly coating the surface of a flexible sheet layer with the hydrophobic flame-retardant adhesive, adhering a layer of aluminum-foil paper to the surface of the adhesive, carrying out connection compounding on the aluminum-foil layer of the aluminum-foil paper and the hydrophobic bonding layer, and calendaring by a calendaring machine to obtain the self-adhesive multilayer composite flexible decoration sheet. According to the invention, the prepared anti-oxidation acrylic polymer emulsion contains a large amount of aldehyde groups, the NH2-BZ surface contains a large amount of amino groups, the degree of the cross-linking polymerization of the aldehyde groups and the amino groups is large, the bond energy of the formed -C=N- double bonds is high, and when NH2-BZ is subjected to cross-linking polymerization through the emulsion, the binding capacity between mineral powder ions is large and the bond energy is high, so that the tensile strength of the sheet is effectively improved.

The invention discloses a preparation method of whitening cosmetics containing castor bean extracts: the first step: extracting castor bean, cassia twig, Bupleurum, dogwood and rose extracts with ethanol; second step: extracting C18 alcohol, After heating and mixing phytate, glycerin, and stearic acid, tert-butyl hydroquinone is added to dissolve to obtain an oil phase; the third step: adding borax and glycerol monostearate to the Chinese herbal medicine extract and the refined water are mixed to obtain the water phase; the fourth step: adding the oil phase to the water phase for emulsification, and adding essence to obtain the cosmetics with whitening and freckle-removing effects. The cosmetic of the present invention can improve skin metabolism, promote skin blood circulation, eliminate pigmentation, and make skin more delicate, smooth, tender and elastic.

The invention discloses a road petroleum asphalt anti-ageing agent, which comprises an additive B and a foundation soft component C, wherein the additive B accounts for 10-60 percent by weight ratio, and the foundation soft component C accounts for 90-40 percent by weight ratio; the foundation soft component C is road petroleum asphalt or aromatic hydrocarbon-rich component or a mixture of the road petroleum asphalt and the aromatic hydrocarbon-rich component; the additive B comprises the following components in the weight ratio: 30-55 percent of a radical scavenger, 15-30 percent of peroxide decomposer, 10-20 percent of light stabilizer and 10-40 percent of metal ion complexing agent. A preparation method for the road petroleum asphalt anti-ageing agent comprises the following steps: heating the foundation soft component C to 70-150 DEG C; respectively adding all the components in the additive B under the stirring condition; and evenly stirring to obtain the road petroleum asphalt anti-ageing agent. The road petroleum asphalt anti-ageing agent disclosed by the invention has the characteristics that anti-ageing performance is good, the use level is low and the compatibility between the road petroleum asphalt anti-ageing agent and the asphalt is good, and is capable of restraining and preventing chain reactions caused on the road petroleum asphalt because of heat, oxygen, light and metal ions, and prolonging the service lives of asphalt road surfaces.

The invention discloses a preparation method of whitening cosmetics containing cinnamon twig extract: the first step: extracting the extracts of cinnamon twig, Bupleurum, dogwood and rose with ethanol; second step: extracting C18 alcohol, inositol six Phosphate ester, glycerin, stearic acid are mixed and melted after being heated, and the oily phase is obtained after adding tert-butyl hydroquinone to dissolve; the third step: adding borax, glycerol monostearate, purified water to the Chinese herbal medicine extract The water phase is obtained after mixing; the fourth step: the oil phase is added to the water phase for emulsification, and essence is added to obtain the cosmetic with whitening and freckle-removing effects. It can improve skin metabolism, promote skin blood circulation, increase skin nutrition, effectively remove free radicals, eliminate pigmentation, lighten skin wrinkles and spots, and make skin more delicate, smooth, white and elastic.
