Using Texture Analysis to Substantiate Hair Care Claims

Texture analysis provides quantitative information about a material’s response when deformed by a controlled force. When texture analysis is applied to hair treated with various conditioners and styling fixatives, the results can help substantiate claims made about the effectiveness of these hair care products.

A Screen for Microbial Contamination

Celsis International introduces the next generation in bioluminescence technology that screens for microbial contamination of personal care products.

BioScreen Offers Asian Panels

Beginning fall 2006, BioScreen will begin offering Asian subject panels.

API Campaigns Against Animal Testing for Cosmetics

The Animal Protection Institute (API), a US national non-profit animal advocacy organization, announced the launch of a campaign to combat misleading animal testing labeling practices...

A Screening Technique for Antiperspirant Testing

A standardized in vivo test design for screening up to eight antiperspirant formulations in one panel is described. Dose-response curves for new raw materials or formulations can be performed in the same panel.

Determination of the In Vitro SPF

A ring test at six European test centers showed that SPF evaluations with good reproducibility and comparability could be obtained by an in vitro protocol measuring either transmittance or erythema-effective irradiance of product samples applied on PMMA plates.

Subjective Skin Condition And Its Association With Objective Skin Measurements

From a group of 302 volunteers, the authors obtained both selfreported Subjective evaluations of skin condition and objective measurements of skin conditions, and then looked for correlations between the subjective and objective skin measures.

AMS Revolutionizes Absorption and Metabolism Studies

Quantification of percutaneous penetration and metabolism of skin care ingredients has seemed daunting; however, new technology provides a ready solution for the problematic arena. Accelerator mass spectrometry (AMS) is a new analytical method that measures a biological response better than the existing technique.

In Sight--Extrasensory Perception in Product Development

Through his experience of working with consumers, Avery N. Gilbert, president of Synesthetics Inc., has discovered that the challenge is not so much discovering what consumers want as interpreting what they think they want.

Oxford Neurosurgeon Supports Animal Testing for Cosmetics

An Oxford, UK-based neurosurgeon who was one of the first scientists to publicly support the use of animals in medical research also condones their use to test cosmetics.

A Dermatologic View--Bioengineering Analysis of Water Hydration

The water content of the stratum corneum (SC) influences almost every biophysical property measurable at the skin surface. Water hydration can be measured using the plastic occlusion stress test (POST) or the water sorption-desorption test (WSDT).

ISPE Presents Complete Immersion SPF Testing

ISPE Laboratories presents a new method to evaluate the solar protection factor of water-resistant products.
