Properties of Surfactants: Emulsions
The metastable nature of two insoluble materials is critical to understanding the nature and performance of emulsions. This metastability and the requirement that the emulsion be cosmetically appealing offer unique challenges to the formulator.

Hydrophobically Modified Inulin: A Novel Polymeric Surfactant and Emulsion Stabilizer
After a short introduction illustrating the basic principles for steric stabilization by polymeric surfactants, the authors describe a novel polymeric surfactant that consists of hydrophobically modified inulin and demonstrate that it is an effective stabilizer for O/W emulsions, suspensions, nano-emulsions and multiple emulsions.

Pop the Cork:
Quercus suber
for Naturally Sourced Antioxidants and Emulsion Stability
Consumers demand better and more sustainable alternatives. Further, some bioactive ingredients register greater biocompatibility. This has driven the industry to search for plant-derived compounds with biological activity.
Quercus suber
L., or cork oak, is shown here to provide an interesting option.

A Surfactant/Biopolymer Stabilizer for Emulsions
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.

MIT Mixes Emulsions That Stick
As the cliché goes, oil and water do not mix. Research in
Nature Communications
may have found a way around this, forming emulsions from the bottom up using condensation and cooled oil.

Patent Pick: Emulsion Stability with Amphiphilic Anisotropic Powder
Patent Picks are chosen by the editors from publicly available sources. Today's technology, from AMOREPACIFIC Corp., relates to an amphiphilic anisotropic powder-containing emulsion with excellent stability.
Methods/Tools
Enabling Advanced Emulsions in Microchannel Architecture
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.

Uniquely Stable Emulsions Revealed Through Freeze-fracture Transmission Electron Microscopy
Researchers investigated the structures and features of emulsions made with different emulsifiers via freeze-fracture transmission electron microscopy. Potassium cetyl phosphate formed more multi-lamellar spheres than other emulsifiers, and aggregated homo-domains on top of lamellar sheet surfaces and multi-lamellar spheres. These homo-domains are likely to be responsible for the excellent emulsion stability achieved.

Clean and Green: A Review of Modern Day Surfactants and Emulsifiers
Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.
