The problem to be solved by the present invention is to provide: a method for producing a tablet, such as a carbonate-spring-type bath agent, which is so designed that a neutralization reaction can occur vigorously and efficiently in the inside of the tablet in spite of a fact that the pH value of an aqueous solution into which the tablet is dissolved is neutral, carbon dioxide gas bubbles having as small sizes as possible can be released continuously for a certain period of time and therefore a large portion of the generated carbon dioxide gas can be dissolved in water without dissipating the carbon dioxide gas to air to thereby increase the total concentration of carbon dioxide components in water, and the carbon dioxide gas that contacts with the skin can be converted into a bicarbonate ion readily due to the pH value of the aqueous solution so that the bicarbonate ion can be absorbed through the skin; and the tablet. The solution for the problem is a method for producing a tablet by carrying out compression molding in the presence of an organic acid in an amount of 1 / 10 to 1 / 3 of the amount of a bicarbonate salt (sodium bicarbonate or potassium bicarbonate) and polyethylene glycol in an amount of 1 / 100 to 1 / 5 of the amount of the bicarbonate salt, wherein the tablet is produced by compression molding in such a manner that an aqueous solution in which the tablet is dissolved can have a pH value of 5.5 to 8.5, the hardness of the tablet becomes 15 kg or more, and each of the diameter and the thickness direction of the tablet becomes 7 mm or more.

Electrostatic latent image developing toner capable of providing a sufficient image density and being free from incorrect transferring even when a toner consumption speed is high, or an insufficient toner charge amount or a non-uniform charge amount distribution is likely to occur. Electrostatic latent image developing toner containing coloring particles including colorant and binding resin, wherein the work function X(eV) of the toner in work function measuring and the gradient A of standardized photoelectron yield (standardized photoelectron yield / exciting energy) (1 / eV) with respect to exciting energy are within ranges, 5.350.

The invention discloses a mosquito-repellent perfume and a preparation method thereof, and relates to a perfume. The invention provides a mosquito-repellent perfume having little dosage and long effective mosquito-repellent time, and a preparation method thereof. The mosquito-repellent perfume comprises the following raw materials in percentage by mass: 3 to 5 percent of deet, 3 to 5 percent of emulsifier, 0.2 to 0.5 percent of beta-cyclodextrine, 0.05 to 0.1 percent of methylparaben, 0.2 to 0.5 percent of perfume, 3 to 6 percent of glycerin, 0.7 to 1 percent of sodium chloride, 15 to 20 percent of ethanol and the balance of water. The preparation method comprises the following steps of: adding the water, the ethanol, the deet, the emulsifier and the beta-cyclodextrine into a reaction kettle, and stirring to obtain a mixture A; adding the glycerin and the perfume into the mixture A, and stirring to obtain a mixture B; and adding the methylparaben and the sodium chloride into the mixture B, stirring, standing and defoaming to obtain the mosquito-repellent perfume. The obtained mosquito-repellent perfume is transparent liquid.

The process of bleaching gauze with ozone water includes: compounding ozone water through introducing weak acid water solution into a barrel and adding surfactant; bleaching gauze after being enzyme scoured, alkali washed and water washed with ozone water in a bleaching kettle, and washing bleached gauze with cold water and hot water. During the bleaching process, ozone water is circulated between the bleaching kettle and the compounding barrel, and ozone is introduced into the compounding barrel to maintain the concentration of the ozone water. The process can bleach gauze homogeneously and the bleached gauze can reach whiteness over 90 %.
