Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part II, Nanoparticle Characterization
By: Johann W. Wiechers, PhD, JW Solutions; and Eli…
Part I of this review on Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs) as delivery systems for cosmetic actives appeared in the October 2010 issue of Cosmetics & Toiletries magazine. Part II, presented here, describes how to characterize SLNs and NLCs; part III, in March 2012, will discuss the stability and occlusion properties of actives and liquids in SLNs and NLCs, and examine their efficacy. Finally, part IV, in May 2012, will discuss the use of SLNs and NLCs in cosmetic products.

Improving Deposition From High-water Formulas Using Amphiphilic Polymers
By: Mussarat Noor; Richard Goddard, PhD; and Arnol…
Effective high-water skin care systems may play an important role in addressing emerging market consumer needs. The present study considers the challenges of such systems, particularly regarding the deposition of ingredients across water solubilities, and proposes an amphiphilic cationic polymer as one possible solution.

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.

Protection of Retinol in Organosilica Microparticles
By: Kim S. Finnie, PhD; and Chris Barbé, PhD, Cera…
In this article, retinol encapsulated in organosilica microparticles (12–14% w/w) having an average particle size of 0.3 micron are shown in a 40-day test period to exhibit enhanced stability to oxidation when compared with similar commercial stabilized retinol products.

Formulating for Delivery From Elastomeric Nonwoven Substrates
By: Stacy A. Mundschau, Scott W. Wenzel and Barbar…
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.

Nanoemulsions vs. Emulsions in the Delivery of Coenzyme Q10 and Tocopheryl Acetate
By: Thanaporn Amnuaikit, Wiwat Pichayakorn and Pra…
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.

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.
