Method for cleaning, employing a surfactant for fine-bubble formation |
摘要 |
A method for cleaning articles using a surfactant which is effective in the formation of stable microbubbles is provided. The surfactant for microbubble formation contains a (poly)oxyalkylene adduct (A) of an active hydrogen atom-containing compound (a) represented by formula (1) Z-[(AO)n—H]p  (1) wherein Z is the residue of an active hydrogen-containing compound (a) with a valence of P resulting from removal of the active hydrogen atom or atoms; A is an alkylene group containing 1 to 8 carbon atoms; n is an integer of 1 to 400; and p is an integer of 1 to 100. The foaming power of a 0.02% by weight aqueous solution of the (poly)oxyalkylene adduct (A) as measured at 20° C. by the Ross Miles test is not higher than 50 mm.
