Abstract

The invention concerns a microemulsion having a mean particle size of 0.15 microns or less comprising: (A) an organopolysiloxane having at least one epoxy containing group per molecule, wherein said epoxy containing group is selected from the group consisting of: ##STR1## where R.sup.1 and R.sup.2 are divalent hydrocarbon groups, and wherein said organopolysiloxane also has carboxyl containing groups present in the amount of 0.5 to 15 moles of caboxyl containing groups per mole of silicon atoms in said organopolysiloxane, wherein said carboxyl containing groups are expressed by the formula: --R.sup.3 --COOR.sup.4 where R.sup.3 is a divalent hydrocarbon group, and R.sup.4 is selected from the group consisting of hydrogen atoms, monovalent hydrocarbon groups and silyl groups expressed by the formula --SiR.sup.5.sub.3, where R.sup.5 indicates the same or different monovalent hydrocarbon groups; (B) a nonionic surfactant; and (C) water. The present invention also comprises a fiber treatment agent whose principal ingredient is the abovementioned microemulsion.
