PURPOSE: To prepare a treating liquid for animal fibers, keratin-based fibers or the like by compounding a surfactant and a diorganopolysiloxane having diester functional groups containing a structural unit expressed by a specified general formula in an aq. medium. CONSTITUTION: A diorganopolysiloxane having diester functional groups having at least one structural unit expressed by formula I per one molecule is compounded in an aq. medium to prepare an aq. emulsion. In the formula I, Z is expressed by formula II (R' is a 1-12C satd. hydrocarbon group, 2-12C univalent alkoxyalkyl group or the like, X is H or methyl group, W is a covalent bond or the like), R is a 1-20C alkyl group or the like, and a is 0, 1, 2. The obtd. aq. emulsion can be preferably used as a coating agent for a cellulose support for cosmetic or dermatological treatment of hair or skin.
