Natural solvent used for producing spray

Abstract

The invention provides a new solvent used for producing spray. The solvent is named as D-limonene and also called D-limonene, the English name of the solvent is D-limonene, the chemical name of the solvent is 1-methyl-4-isopropenyl cyclohexane, and the solvent is essential oil extracted by methods of distilling, solvent-extracting or squeezing fresh peels of rutaceae citrus plants and the like, wherein the content of the D-limonene is over 80 percent; the solvent has the advantages of colorlessness, innocuity, light and fresh smell, high flash point, high boiling point, moderate volatility, small relative density, low surface tension, good inter-miscibility with lipid soluble components, high safety and the like; and the solvent can replace ethanol, isopropanol, petroleum ether, flavorless kerosene and the like to be used as a good solvent for the spray such as air fresher, air disinfectant, hygienic insecticide, mosquito repellent, essential oil incense preparation, essential oil aromatherapy preparation and the like, and is particularly applied to the solvent for the spray for ultrasonic spraying.

Description

technical field [0001] The invention relates to a solvent for producing sprays, which are mainly used in the fields of air freshening, air disinfection, hygienic insecticide, mosquito repellent and the like. Background technique [0002] Spray is a preparation that sprays the solution in the form of mist under normal pressure by means of a certain method. Because it does not contain propellant, it does not require pressure-resistant container packaging. Compared with aerosol that requires propellant to promote atomization , the production process is simpler, and the use, storage and transportation are safer. It is a dosage form widely used in medicine, cosmetics, daily chemicals, disinfection products and hygienic insecticide products. [0003] Pressurized atomization by hand pump is currently the most commonly used atomization method for aerosols. In recent years, a spray product that is directly atomized by ultrasonic waves has appeared on the market. The most typical one...

Problems solved by technology

This kind of intermittent spraying often leaves a small amount of solution on the upper surface of the ultrasonic vibrator after each spraying. When using ethanol and other low-boiling-point, highly volatile solvents, the vapor pressure of the solvent is large and evaporates quickly, while other aromatics Or the mosquito repellent components are generally less volatile than the solvent, and the solvent in the residual solution volatilizes faster, which increases the viscosity of the residual solution. If the spray interval is relatively long, the solution will become viscous and cover the surface of the ultrasonic vibrator. Block the outlet of the upper end of the micropore of the vibrator, because the solution at the lower end of the micropore cannot dissolve and dilute the viscous solute at the upper end in time, so that the spraying is interrupted. If it is not found and treated in time, the solute at the upper end may interact with the falling dust, and then Through complex chemical changes such as oxidation and solidification, a solid film is formed on the upper surface of the vibrator, causing the machine to fail to work normally. If the solute in the upper end of the micropore also undergoes the same change, the situation is even more serious. Only the ultrasonic vibrator can be replaced. restore normal operation of the machine
