PROBLEM TO BE SOLVED: To provide an oil-in-water type emulsion of amino siloxane and to provide a method for using the same. SOLUTION: The invention relates to the oil-in-water type emulsion comprising (i) 100 pts by mass of a polydimethylsiloxane having an aminoalkyl group composed of units represented by general formula (I), R<SP>1</SP><SB>a</SB>R<SP>2</SP><SB>b</SB>SiO<SB>(4-a-b/2)</SB>, and having amine value of≥0.1 mequiv/polydimethylsiloxane (P)g, (ii) a protonating agent, (iii) water and (iv)≤5 pts by mass of a surfactant. The oil-in-water type emulsion free from conventional fault for hydrophobization treatment of a substrate can be obtained by the invention. COPYRIGHT: (C)2006,JPO&NCIPI
