This document provides information on Dow Corning silicone emulsifiers for formulating various types of emulsions. It lists 10 emulsifier products, providing their INCI name, type of emulsion they can create, viscosity, use level and other details. It also includes a decision tree to help determine which emulsifier is best for a given emulsion system being formulated. Tips for successful emulsification include adjusting variables like phase ratio, emulsifier level, shear rate and silicone/oil viscosity. Dow Corning can provide formulation support to achieve a stable emulsion.

Silicone Emulsifier Decision Tree
Emulsification Success Tips
Emulsification success is both an art and a science. It may be necessary to adjust key variables, individually or in
combination. Here are some tips to help you formulate with Dow Corning®
silicone emulsifiers. For specific formulating
advice, please contact your Dow Corning representative.
Define variables:
 Phase ratio
 Emulsifier level
 Silicone/oil viscosity
 Shear
Try increasing:
 Internal phase content
 Emulsifier level
 Silicone/oil viscosity
 Shear
Emulsion Success
(Water-in-silicone, water-in-oil,
water-in-silicone+oil)
Try decreasing:
 Internal phase content
 Emulsifier level
 Silicone/oil viscosity
 Shear
Did emulsification occur?
 Not possible to add the
entire aqueous phase
 Emulsion breaks
during process
Is the emulsion stable over time?
Is there sedimentation?
