Researchers Mimic the Lymphatic System in Animal Alternative Chip
A chip created by L'Oréal and Hurel Corp. is designed to replace the local lymph node assay, a test often performed on cosmetic raw materials. In addition to saving animals, the chip is also said to be less expensive than animal testing. Hurel developed the working microfluidic portion of the chip.

Evaluating Water Permeability and Occlusion in Wound Dressings and Topical Cosmetics
By: Hongbo Zhai, MD, and Howard I. Maibach, MD, Un…
The present study uses an evaporimeter to measure the degree of water loss from in vitro skin samples covered by occlusive and semi-occlusive wound dressings to serve as a model for determining the effectiveness of occlusive cosmetic formulations. The purpose of this work was to develop a model for determining the effectiveness of occlusive cosmetic formulations.

Researchers Initiate Automation of Skin Model Production
Instead of just a single layer skin model of a single cell type, the researchers have access to a patent-protected skin model that consists of two layers with different cell types. The researchers liken this model to a perfect copy of human skin and are in the process of developing the first fully-automated process chain for manufacturing two-layer skin models.

In Vitro Model for Decontamination of Human Skin
By: Hongbo Zhai, MD, University of California; and…
The present study utilized an in vitro model to compare the decontamination capacity of three model decontaminant solutions: tap water, isotonic saline and hypertonic saline. Human cadaver skin samples were dosed with radio-labeled [14C]-formaldehyde and the surface skin of each sample was washed after each exposure with one of the three model decontaminant solutions.
