Abstract
Disclosed is an emulsion formed using, as an emulsifier, 0.01 to 30 parts by weight of a perfluoroalkylethyl phosphonic acid salt represented by the general formula: CFCHCHP(O)(OM)(OM) [III] (M: a hydrogen atom, ammonium salt, or organic amine salt, M: an ammonium salt or organic amine salt, n: 1 to 6), based on 100 parts by weight of a perfluoropolyether oil represented by the general formula: RfO(CFO)(CFO), (CFO), Rf' [I] (Rf and Rf′: C-Cperfluoroalkyl groups, p+q+r: 2 to 200) or the general formula: F(CFCFCFO)CFCF[II](n: 2 to 100), or a perfluorocarbon compound. In spite of using, as an emulsifier, a compound having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, the emulsion exhibits excellent emulsification stability, and therefore can be effectively used as a surface-treating agent, such as a mold-releasing agent.
