Properties of a Pseudoceramide Multi-Lamellar Emulsion In Vitro and In Vivo
Tests of a pseudoceramide multi-lamellar emulsion formulation for its stability and its assistance to barrier recovery in vivo on damaged skin suggest dermatologic and cosmetic possibilities.

Assessing the Impact of Hair Damage Types on Color Retention
This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.

The Perplexing Topic of Hair 'Type': How Do We Classify Hair?
Most hair-related properties and issues can be rationalized by fiber size and shape, and/or the consequences of extreme conditions. However, the varying reactivity of different hair types with chemical treatments suggests potential differences in structure.

Quantifying Benzophenone-3 and Octyl Methoxycinnamate in Sunscreen Emulsions
The authors have validated a high performance liquid chromatographic (HPLC) method for the quantitative determination of benzophenone- 3 and octyl methoxycinnamate present in sunscreen emulsions.

Correlation of Long-term Physical Stability of Emulsions with the Short-term Rheological Measurements
Three short-term rheological measurements on some model personal care emulsions showed good correlation with long-term physical instability of the emulsions. Use of these rheological measurements can shorten the time to test the stability of new formulations.

[video] Student Poster: Texture Analyzer vs. Panelist Perception of Emulsions
Texture analyzer vs. panelist ratings of emulsions: How do they compare? This student sought to find out, as her poster presentation and the Midwest SCC TeamWorks event describes.

Zeta Potential and Particle Size to Predict Emulsion Stability
Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.

Liquid Crystals in O/W Emulsions with Urea: Development and Testing
Using a ternary phase diagram, the authors developed systems based on nonionic surfactants, light paraffin oil, water, and (optionally) urea. Systems in which lamellar liquid crystals formed and in which urea was an ingredient showed higher occlusive power and lower TEWL in in vitro tests.

Patent Picks—Microbe Separation, Emulsion Arrays and Salicylic Acid Delivery From Powder
Patent Picks are compiled by the editors from publicly available sources. This edition features processes for identifying microorganisms, forming emulsion arrays and delivering salicylic acid from powder.
Method/Process
Using Skin Models to Assess the Effects of a Skin Care Emulsion on Skin Barrier Function
This study utilizes a 3D skin model to investigate barrier repair after damage with SDS and application of a skin care emulsion; it also demonstrates the suitability of using 3D skin models to study barrier repair.

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.
Method/Process
Testing A New Platform for Skin Care Emulsions
The authors describe how to test an ingredient for its potential as a skin care emulsion platform using, as an example, a new starch-based ingredient called hydroxypropyl starch phosphate.

Study Reveals Factorial Model to Predict O/W Emulsion Stability
A study published in the
Journal of Pharmacy & Pharmacognosy Research
confirmed an approach to predict the physical stability and quality of o/w cosmetic emulsions using full factorial design.

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.

Anti-aging Effects of Massage and Electricity
Recent research reported in
Health Sciences
shows skin moisture, facial fat and wrinkle depth improvements by classic facial massage, and increased oxygen uptake by electrical stimulation.

Mechanisms of Tape Stripping and Protein Quantification
In this article, several methods to quantify the protein collected by tape stripping are described, including traditional gravimetric methods as well as novel colorimetric and visible spectroscopic techniques. Further, one colorimetric method is described to effectively determine the keratolytic efficacy of various materials in vivo, suggesting additional roles for this method.

[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.
