DeodorantA variety of foul odors and unpleasant odors occur in almost all environments where people engage in activities. Different sources have different degrees of diffusion, making them difficult to control and eliminate. Existing deodorization methods include neutralization methods, physical methods, masking methods, biochemical methods, etc. However, they all have their limitations. They should be selected according to conditions and applied rationally to achieve good deodorizing effects. For example, the neutralization method is only applicable to acidic or salt-based odors; the physical method mainly eliminates environmental odors through adsorption, so it can only be used in a small range, and it takes a long time to reach adsorption equilibrium; the masking method cannot fundamentally eliminate odors.In response to the above situation, Japan has proposed a new type of deodorant. It uses three kinds of tricyclic olefin derivatives as active ingredients. In the formula, R1 is a methyl group, a carboxymethyl group or a formyl group, and R2 is a hydrogen atom, a formyl group or an acyl group. This compound has a significant deodorizing effect on mercaptans and hydrogen sulfide, and has no irritating effect on the eyes, nose, and throat. Its deodorizing mechanism is not yet clear. It is thought that it may be because the active three-membered ring in the molecule easily reacts with compounds such as thiols to generate low vapor pressure compounds, thereby achieving the deodorizing effect.This deodorant can be applied in liquid, solid, powder or aerosol form. Solvents, active agents, preservatives, spices, pigments and other substances can also be added as needed. During production, in order to improve the compatibility between the deodorant and the solvent, organic solvents such as methanol, ethanol, propanol, methyl cellosolve, ethyl cellosolve, butyl cellosolve, glycerin, ethylene glycol, and propylene glycol can be added. In order to dissolve or emulsify deodorants and fragrances, nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene phenyl ether, polyoxyethylene alkyl ester, polyoxyethylene, and polyoxypropylene; anionic surfactants such as alkyl aryl sulfonates, alkenyl sulfonates, and alkyl ether sulfonates; and cationic surfactants such as alkyl pyridine halides, alkyl trimethylammonium chlorides, and alkyl xylylammonium chlorides can be used. In addition, a certain amount of preservatives such as p-carboxybenzoate can be added. When the dosage of the compounds of formulas (I) to (II) …
