Testing Tactics--In Vitro Sensitization Models: Current Progress

Several interesting and promising approaches to in vitro skin sensitization testing are in development. Perhaps it will not be long before they are deemed valid and reliable alternatives to animal testing.

Enhancing, Measuring Skin Penetration

Skin penetration is of great interest to personal care formulators for many reasons. Following are a few recent findings.

Tech Edge--Optical Tools to Examine the Structure of Cosmetics Products

To monitor or anticipate what can happen in the creation of a cosmetic product when components are combined and as time passes is no trivial task especially when compounded with the psychophysical needs for the product to fit a specific concept and to spread, feel, pour and appear elegant.

A Dermatological View: Antioxidant Inhibits UV Erythema In Vivo in Humans

Described here was an in vivo model to determine antioxidative capacity of a topical skin care emulsion versus the emulsion’s vehicle on human skin that was exposed to UVR. Results suggest the test emulsion and its vehicle control inhibited the induction of erythema and reduced inflammation caused by the UV exposure.

India Looks to Reduce Animal Testing

Reducing animal use for testing drugs and cosmetics was the focus of a recent congress held in Chennai, India.

Testing Tactics: In Vitro Methods to Test Materials for UV Protective Capabilities

The methods described in this article highlight some of the markers that can be used to assess the UV protective effects of a test material. All of these markers represent either an index of UV-induced damage to the cell or the cell’s response to the damage.

EPAA Reports on a Year of Progress Towards Animal Testing Reduction

The EPAA recently presented a report covering the actions made toward the replacement, reduction and refinement of animal testing.

Expanded Parameters for Particle Analysis

Fluid Imaging Technologies has launched a particle analysis instrument that permits 23 measurement parameters.

Evaluating Droplet Size in Nanoemulsions from a Novel Emulsifier System

This article describes two sophisticated techniques to measure the diameter of emulsion droplets on the nanometer scale and uses those techniques to test a new emulsifying agent capable of spontaneously creating emulsions with droplet sizes smaller than 300 nm.

New Directions for Sensitive Skin Research

This brief review provides an insight into the current standing of sensitive skin research, including recent findings on the possible role of nerve growth factor as an underlying mechanism and predictive tool for sensitive skin.

BASF Establishes Enzyme Alliances

BASF has signed a cooperation agreement with the Center of Excellence in Biocatalysis, Biotransformation and Biomanufacturing (CoEBio3) in Manchester, UK.
