Comparatively Speaking—Entanglement vs. Overlap

By: Anthony J. O'Lenick Jr., Siltech LLC, and Thom…

This edition of "Comparatively Speaking" describes the difference between the critical molecular weight of entanglement and critical concentration of overlap. These concepts are important for formulators to grasp since they deal with altering the physical properties of a finished product.

Dispelling the 'Law of Wiechers' and Maximizing Actives Delivery

By: Johann W. Wiechers, PhD, JW Solutions

Jonathan Hadgraft, PhD, named "The Law of Wiechers in Cosmetics" after his friend and colleague. This law argues that all actives should be formulated at 3% for maximum delivery, which Wiechers recently discussed in honor of Hadgrafts's 60th birthday.

NY Chemists Develop Nature-inspired Responsive Molecule

An amphiphilic molecule designed by chemists at The City College of New York is said to respond to stimuli in a similar manner to the Venus fly trap by changing its structure when heated slightly, then reverting to its original form when cooled.

Comparatively Speaking: Simple Salt vs. Ionic Liquid

By: Anthony J. O'Lenick Jr., Siltech LLC

Unlike common salts, ionic liquids are salts in which the ions are poorly coordinated, resulting in molecules that are liquid below 100°C. The use of ionic liquids will aid the formulator in improving delivery efficiency.

Electrifying Skin Delivery

By: Katie Schaefer, Cosmetics & Toiletries…

Iontophoresis is a well-known, noninvasive method that uses a small electric charge to deliver chemicals through the skin. However, according to Gregory Schultz, PhD, and Daniel Gibson, a professor and doctoral candidate, respectively, at the University of Florida, this method of delivery can have its drawbacks. Together with co-inventor, Sonal Sanjeev Tuli, MD, the team developed a method to iontophorese macromolecules into tissue such as the skin without causing damage; however, initial research focused on the eye.
