An Herbal Blend for Antiaging Effects: TCM in Personal Care
Jun 19, 2013 | Daniel Schmid, Esther Belser and Fred Zülli, Mibelle Biochemistry
A combination of Chinese herbs is shown here, by gene array analysis, to stimulate the skin’s resistance against free radicals, oxidative stress and toxic molecules, while also reducing extracellular matrix degradation. The extract also is shown to help against skin irritation in vivo.
Clinical Relevance of Topical Active Delivery Systems in Cosmetics
Jun 19, 2013 | Haw-Yueh Thong, MD, MS, Dnational Taiwan University Hospital and Howard I. Maibach, MD, University of California
Depending on a drug or cosmetic ingredient’s intended target, topical delivery systems are broadly categorized as either transdermal drug or dermal drug/cosmetic. Transdermal drug delivery (TDD) is the controlled release of drugs through intact skin to obtain therapeutic levels systematically and to affect specified targets for specific purposes such as contraception, among others.
Nanotechnology and Skin Delivery: Infinitely Small or Infinite Possibilities?
Jun 19, 2013 | Johann W. Wiechers, PhD, JW Solutions
Nanoparticles have been defined as single particles with a diameter less than 100 nm,4 which includes titanium dioxide in transparent, inorganic sun care products, and is usually extended to 200 nm to include the zinc oxide in those products. But nanoparticles are only a subset of nanomaterials, which can also include cyclodextrins and liposomes.

Nanoemulsions vs. Emulsions in the Delivery of Coenzyme Q10 and Tocopheryl Acetate
Jun 14, 2013 | Thanaporn Amnuaikit, Wiwat Pichayakorn and Prapaporn Boonme, Prince of Songkla University
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.
Sodium Laurylglucosides Hydroxypropyl Sulfonate for Sulfate-free Formulations
Jun 14, 2013 | Robert J. Coots, PhD, Colonial Chemical Inc.
The use of sulfonated alkyl polyglucosides (SAPG) to replace lauryl sulfates and lauryl ether sulfates in sulfate-free formulations has previously been discussed. These primary surfactants were created with environmental and human safety in mind. The current paper describes more recent work with this material, specifically focusing on the lauryl version of SAPG.
