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.

When developing moisturizers intended for application via nonwoven substrates, formulators must consider the hydrophobic oils, the affinity of those oils to the substrate, the add-on to the substrate and the stability of the compositions on the substrate. With these considerations, moisturizing formulations were developed and coated onto laminated substrates whose moisturization efficacies were evaluated as described here.

This article compares the ability of mixed emulsifier nanoemulsions and polysorbate 60 emulsions to deliver coenzyme Q10 and tocopheryl acetate into the skin. In vitro skin penetration data shows that in newborn pig skin, nanoemulsions can deliver higher amounts of both actives than emulsions.

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.

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.

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.
