Cosmetotextiles - Skin care you can wear
Authors: Raymond Mathis, Annette Mehling
http://www.scf-online.com/english/46_e/cosmetotextiles46_e.html
Cosmetotextiles are textiles with cosmetic properties, but they can also be a vehicle for other active substances or functions. This article discusses microencapsulation as a key technology for cosmetotextiles, and treats the regulatory framework which in the past was based on various approaches. With regard to the cosmetic efficacy of cosmetotextiles, the safety of ingredients, quantity of the product used and synergies between type of textile and cosmetic finish are aspects which are of major importance.

The article treats a new concept for the effective transfer of substances to fabrics. The special technology of "Wet dryer sheets" makes clothes pleasant to wear, protects them from wear and tear, improves color maintenance and increases moisture uptake. They may contain skin care ingredients that provide protection for sensitive skin, thus enabling manufacturers to meet specific consumer needs.

Perception, measurement and visualization of cosmetic effects
Authors: Torsten Clarius, Olga Freis, Dominique Gauché, Marie-Danielle Vazquez-Duchêne, Marie-France Zambaux, Gilles Pauly, Andreas Rathjens

Modern visualization techniques not only help improve quantitative evaluations of test results but also lead to presentations which are more convincing for the consumer. Laboratoires Sérobiologiques are steadily increasing this competence to document the efficacy of skin and body care products. Three-dimensional animations of detailed dermal structures of individual cells are suited to present scientific topics in an easy way and may contribute to the cosmetic manufacturer's credibility.

Determination of the substantivity of emollients to human hair
Authors: Hans-Martin Haake, Hélène Lagrené, Angela Brands, Wolf Eisfeld, David Melchior
Link: http://www.scf-online.com/english/45_e/substantivity45_e.htm
This article focuses on the determination of silicones and hydrogenated didecenes deposited on human hair from shampoo applications. For silicones, ICP-OES (induced coupled plasma optical emission spectroscopy) of extracts and X-ray fluorescence analysis of hair strands without any further sample preparation were applied. Three shampoos from the European and Asian markets were investigated at repeated shampoo applications followed by the determination of the removability with sodium laureth sulfate. Hydrogenated didecenes were quantified by GC-MS of extracts. A transparent shampoo containing 1.8% of hydrogenated didecenes delivered via a nanoemulsion was examined in the same way as the commercial shampoos. The substantivity data were compared with performance data from combability determination and hair volume measurements. Good correlations of analytical data and performance profiles were obtained.
