Green  (74)  Attorney, Agent, or Firm-Jeffrey  V.  Bamber; Jason  J.  Camp  Stable, aqueous compositions for treating surfaces, espe› cially fabrics, comprise: a relatively low molecular weight  polyalkyleneoxide polysiloxane surfactant; a buffering agent  to maintain the  pH  of the composition in the range of from  about 4 to about 10, preferably from about 5 to about 9.5,  and more preferably from about 6 to about 9; and an aqueous  carrier. The compositions can further comprise catoinic  surfactants to further enhance the spreading and/or fabric  penetration ability of the compositions. The compositions  can further comprise a variety of other optional ingredients.  Methods of treating surfaces include methods wherein the  compositions are contacted with surfaces, especially fabrics,  to reduce malodor impression on the surfaces and/or reduce  the appearance of wrinkles in fabrics.
