A Surfactant/Biopolymer Stabilizer for Emulsions
By: T. Tadros, Wokingham; S. Leonard and M.-C. Tae…
An emulsifier/biopolymer system using a mixture of nonionic surfactants and two biopolymers was developed. The surfactants provide effective steric stabilization against coalescence, whereas the biopolymers provide a high residual viscosity and yield value, thus providing stability against creaming. The mechanism of stabilization is discussed in terms of the synergy between the two biopolymers.

Enabling Advanced Emulsions in Microchannel Architecture
By: L. Silva, A.L. Tonkovich, D. Qiu, P. Neagle, K…
An innovative emulsification technology is demonstrated, which can be applied to surfactant-free emulsions and has the propensity for stimuli-responsive behavior. The technology can be used to allow previously difficult product formulations with shear-sensitive materials and controlled, droplet size distribution.
