(54) Gel-like emulsion and O/W emulsions obtained from the gel-like emulsion.
(57) A gel-like emulsion is prepared by adding an oil to a surfactant continuous phase formed of a monoalkyl phosphate
salt, polyhydric alcohol and water.
The gel-like emulsion is scarcely dependent on temperature, and a fine and uniform O/W emulsion prepared
from the gel-like emulsion reveals excellent stability at the
time of production and at storage. The gel-like emulsion contains only a small amount of alkyl phosphate surface active
agent of low irritativeness, so that it is usable for cosmetics,
Pharmaceuticals, industrial products and the like, which are
required to have low irritation and high safety.
