Dow Corning polysiloxanes can be readily formulated to oil-in-water
micro or macro/mechanical emulsions. Micro emulsions are so-called due to
their very small average size particle size.
Successful production of emulsions depends on choosing the correct HLB
(Hydrophile Lipophile Balance),i.e., matching the HLB of the surfactantwith
that of the polysiloxane which is being emulsified.
The large number of surfactants available makes any trial and error system
difficult and time-consuming. The easiest way to begin to identify the HLB of a
system is to use the ‘HLB method.’ This involvespreparing emulsions with a
range of HLB values.
