PROBLEM TO BE SOLVED: To provide a detergent which has not only excellent cleaning ability for a printed board and miniature parts, but also safety, by compounding a hydrocarbon solvent, a polyoxyalkylene dialkyl ether and a specific aromatic compound such as benzil alcohol. SOLUTION: This detergent composition comprises (A) a hydrocarbon solvent, (B) a polyoxyalkylene dialkyl ether of formula (I) (wherein, each of R<1> and R<2> is a 1-6C alkyl group or a 2-6C alkenyl group, (m) is 2 to 4, (n) is 1 to 4, and the groups indicated within () may be different one another), and (C) a monocyclic aromatic compound of formula (II) (wherein R<3> is H, a 1-3C alkyl group, a 2-3C alkenyl, (p) is 0 to 2, (q) is 2 to 4 and (r) is 0 to 4 and the groups indicated with in () may be different one another). With respect to (A), a hydrocarbon having 12 to 14 carbon atoms is used for maintaining low flamability and the detergency for an interstice. Particularly, a 12-14C monoolefin is preferred. As (B), use is made of a compound wherein the group indicated within () is oxy-ethylene or oxy-propylene. (C) is particularly benzil alcohol. A formulation comprising 12 to 20wt.% of (B) and 7 to 30wt.% of (C) is preferred. Addition of an amine compound to this detergent composition results in further enhancing the detergency. |
