This invention relates to stable microemulsion cleaners having decreased volatile organic content comprising (a) a non polar, organic hydrocarbon solvent system comprising (i) an aromatic solvent and/or (ii) an aliphatic solvent, (b) an ethoxylate of an aromatic or aliphatic hydrophobe; (c) a glycol ether or ethylene glycol; a primary amino alcohol; water, and other components for specific applications. These cleaners can be used for removing oil, grease, and baked-on carbon deposits from metal surfaces, and are particularly useful as engine shampoos and cleaners for air coolers.
Cette invention se rapporte à des nettoyants en micro-émulsions stables ayant une teneur en matières organiques volatiles réduite et comprenant: (a) un système de solvant à hydrocarbure organique non polaire, contenant (i) un solvant aromatique et/ou (ii) un solvant aliphatique; (b) un éthoxylate d'un agent hydrophobe aromatique ou aliphatique; (c) un glycol éther ou un éthylène glycol; un alcool à amine primaire; de l'eau; ainsi que d'autres constituants pour des applications spécifiques. Ces nettoyants peuvent être utilisés pour enlever l'huile, les graisses et les dépôts de carbone cuits de surfaces métalliques et ils sont particulièrement utiles comme shampoings pour moteurs et comme nettoyants pour refroidisseurs à air.
