Abstract

Stable, aqueous compositions for treating surfaces, especially 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.
