A water-in-oil microemulsion comprises:
(a) an oil phase
(b) an aqueous phase
(c) at least one emulsifier, and
(d) at least one aliphatic diol of the formula
where
R and R" are independently hydrogen or C1-C18 aliphatic groups,
each R' is independently hydrogen or a C,-C20 aliphatic group,
n is an integer of 1-4, with the provisos that the number
of carbon atoms in R is different than the number of carbon atoms in R", and
the total number of carbon atoms in I is from 5 to about 25.
The aliphatic diol (1) is preferably 2-ethyl-1. 3-hexanediol. The microemulsions are useful as fire-resistant hydraulic fluids.
