InactiveUS20100075882A1Excellent textureExcellent stabilityCosmetic preparationsMake-upMoisturizerOxide
The present invention was made in view of the above-described circumstances, and an object of the invention is to provide an external skin preparation having a rough skin improving effect, excellent in texture in use, especially excellent in smoothness, free of sticky feeling, and excellent in stability. Another object is to provide a skin cleanser excellent especially in usability and a cosmetic removing effect. That is, the external skin preparation of the present invention is characterized by comprising a block-type alkylene oxide derivative represented by the below-described formula (I).
[formula 1]
Y—[O(EO)a-(AO)b-(EO)c-R]k  (I)
  • (In the formula, Y is the residue given by removing hydroxyl groups from a polyhydric alcohol having 3 to 6 hydroxyl groups, and k is the number of hydroxyl groups of the polyhydric alcohol. EO is an oxyethylene group, AO is an oxyalkylene group having 3 to 6 carbon atoms, and they are attached in a block-type, respectively. The products, a×k, b×k, and c×k, are the average addition mole numbers of the oxyethylene group, the oxyalkylene group having 3 to 6 carbon atoms, and the oxyethylene group, respectively, and 0≦a×k≦100, 1≦b×k≦100, and 0≦c×k≦100, however, (a+c)×k>1. The percentage of all oxyethylene groups in formula (I) with respect to the sum of all oxyethylene groups and oxyalkylene groups having 3 to 6 carbon atoms in formula (I) is 10 to 80 mass %. Rs may be either identical to or different from each other, and they are hydrocarbon groups with 1 to 4 carbon atoms.) The skin cleanser of present invention is characterized by comprising 0.01 to 70 mass % of a block-type alkylene oxide derivative represented by the above-described formula (I) and 0.1 to 20 mass % of a moisturizer.

Method for preparing urea peroxide containing organic titanium by recrystallization process

The invention relates to a method for preparing urea peroxide containing organic titanium by a recrystallization process. The method is characterized in that: new metatitanic acid precipitate of citric acid is prepared by neutralizing an iced solution of titanium salt by using alkali; the new metatitanic acid precipitate instead of titanium chloride and sulfate is used as raw materials for synthesizing citricacide-titatnium chelate; the citricacide-titatnium chelate is synthesized by a microwave hot melting chelation process by using the new metatitanic acid precipitate of citric acid as a titanium source and citric acid as an acid solvent and chelant; and the novel urea peroxide fertilizer containing the organic titanium is prepared by the steps of uniformly mixing hydrogen peroxide, acid citricacide-titatnium chelate and urea in a ratio, performing addition reaction on a mixture at the constant temperature of 60 DEG C, and recrystallizing at the temperature of less than or equal to 5 DEG C. The titanium element can strongly promote plant to absorb and convey nitrogen, phosphorus, potassium, other secondary elements and trace elements; the citricacide-titatnium chelate is reacted with hydrogen peroxide easily to form a titanium peroxide compound with high stability; and the citricacide-titatnium chelate can be used as stabilizer of urea peroxide, and synergist of urea peroxide nitrogenous fertilizer.

Fluorescence doping carbon nanometer N,B-CDs catalyst as well as preparation method and application thereof

The invention discloses a fluorescence doping carbon nanometer N,B-CDs catalyst, which is prepared from citric acid, boracic acid and urea as raw materials through a one-step hydrothermal method. Thepreparation method comprises the following steps of using citric acid, boracic acid and urea as prepolymers; providing a carbon source by citric acid; providing a nitrogen source by urea; providing aboron source by boracic acid for further preparing and obtaining the catalyst through the one-step hydrothermal method. The invention also provides application of the catalyst to photocatalytic degradation of methylene blue (MB). The excellent MB photocatalytic degradation capability (the degradation rate is as high as 97.8 percent) can be shown under visible light irradiation. The invention provides a novel preparation method with the advantages that the preparation process is simple, and the economic cost is realized. In addition, the prepared fluorescence doping carbon nanometer material has strong fluorescence; meanwhile, excellent stability and good water solubility are realized, so that good application prospects are realized in the fields of environment restoration, sewage treatment, separation science and the like.

Cationic metal phthalocyanine/carbon nano-tube self-assembled membrane electrode and preparation method thereof

The invention belongs to the field of electrochemical/biological sensors, and in particular relates to a cationic metal phthalocyanine/carbon nano-tube self-assembled membrane electrode and a preparation method thereof, aiming to solve the problems that an existing membrane electrode is non-uniform in surface coverage, low in surface coverage rate and non-steady in electrochemical property, and an existing preparation method is complex in process and high in cost and pollutes the environment. The cationic metal phthalocyanine/carbon nano-tube self-assembled membrane electrode is obtained by alternatively assembling a cationic metal phthalocyanine layer with positive charge and a carbon nano-tube layer with negative charge on a substrate with negative charge and forming a multi-layer membrane electrode with the cationic metal phthalocyanine layer and the carbon nano-tube layer which are alternative. The preparation method disclosed by the invention comprises the following steps: (1), preparing a cationic metal phthalocyanine aqueous solution; (2), preparing carbon nano-tube dispersion liquid; (3), pre-processing the substrate; and (4), preparing the cationic metal phthalocyanine/carbon nano-tube self-assembled membrane electrode.
