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.

New Perspectives in Emulsion Formation

Previously, the theory explaining emulsion behavior was based on the equilibrium contact angle of the particle at the interface; however, Vinothan N. Manoharan, PhD, and his team at Harvard believe the time allowed for the system to reach equilibrium and the force pushing the particle to the interface are equally as important.

Preparing PIC Emulsions with Very Fine Particle Size

A new technology has been developed for the production of o/w phase inversion concentration (PIC) emulsions with a very fine particle size and excellent storage stability. The concept is based on non-ethoxylated emulsifiers and can be easily used for the preparation of impregnating lotions for cosmetic wet wipes.

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.

Formulators Forum--Optimizing Your Emulsion to Meet Marketing Requirements

Cosmetic formulators are given product briefs from our marketing friends and then we go off to the bench to create our masterpiece. After we submit our idea of what we think the brief really meant, someone from marketing gets back to us and tells us that it doesn’t feel right.

Water-based Plant Extract Emulsion Technology

Analyses Recherches Innovation Instrumentale (AR2i) has introduced a water plant emulsion processing technology to enable the production of ultra fine fluid emulsions with extracts of plants.

New Emulsion Technology Makes Formulation Easy

This article describes the use of a novel process technology to prepare high internal phase (HIP) emulsions, which can provide solutions to a number of formulating issues.

Using Nonaqueous Emulsions to Avoid Discoloration Reactions

This article focuses on the physical principles of nonaqueous emulsions and their practical applications in preventing discoloration from ascorbic acid, hydroquinone and dihydroxyacetone.

Microchannel Processing: A Novel Approach to Making Emulsions

In the present article, microchannel emulsification is explored as a process method that precisely adds a dispersed phase into a continuous phase through an engineered dispersion plate. This approach is shown to produce emulsions with smaller droplets having tighter size distributions than conventional means, which leads to stable products with the limited need, if any, for surfactants.

Researchers Suggest New Way to Look at Manufacturing Emulsions

Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) have discovered that stabilized emulsions may take months to years to reach equilibrium. This research has important implications for the manufacturing processes used in pharmaceuticals, cosmetics and foods, among other chemical industries.

GSK Sells Off Part of UK R&D Site, Reinvests in Biotech and Life Sciences

In mid-July, GlaxoSmithKline (GSK) announced plans to sell off part of its UK R&D site to unlock US $554 million in funding to build a campus for biotechnology and other early stage life science companies.

[podcast] The Sound and Scent of Efficacy

"While the consumer will think of ... feeling the softness of hair or smoothness of skin, our research has shown that none of our experiences is just unisensory. ...If we know that perception is multisensory, we start thinking about the role [of other senses]." Learn more from Charles Spence, Ph.D., in this seven-part podcast series, sponsored by Berjé.

Testing the Fate (and Exposure) of Cosmetic Ingredients

Risk and exposure go hand-in-hand. So when researchers dared to publish a new method to assess the exposure and fate of cosmetic ingredients, we couldn't help but give them exposure, in this review.

Consumer Perception of Fine Lines and Wrinkles: Qualitative Assessment

There are varying definitions, associations and overall impressions of fine lines and wrinkles among different consumer segments. The findings of this study offer invaluable insight into consumers’ opinions, and by qualitative in-depth interviews, they provide a well-defined vernacular for aging descriptors. This language is critical for developmental research, consumer evaluation and marketing within the cosmetic industry.
