PURPOSE:To efficiently spray the foamable deodorant by spraying the deodorizing liquid contg. a foaming agent to a malodorous source by using a mechanical foam spraying nozzle having an air intake port. CONSTITUTION:The spraying nozzle has the air intake port just before an injection port and has the mechanism to generate mechanical foam by mixing the air with the deodorizing liquid at the time of spraying. The deodorizing liquid contg. the foaming agent is sprayed to the malodorous source in the state of foam by using this spraying nozzle. One or >=2 kinds of anionic, cationic, nonionic and amphoteric surfactants are used in combination to improve foaming as the foaming agent. The higher effect is obtd. if higher fatty acid, alkanol amine, aliphat. polyhydric alcohol and water soluble high polymer, etc., are added as the stabilizer for foam to the foaming agent at need. |
