A highly sensitive method to determine the washing resistance of artificial hair colors / Erik Schulze zur Wiesche in IFSCC MAGAZINE, Vol. 11, N° 2 (04-05/2008)
[article]
Titre : A highly sensitive method to determine the washing resistance of artificial hair colors Type de document : texte imprimé Auteurs : Erik Schulze zur Wiesche, Auteur ; Siglinde Erpenbach, Auteur Année de publication : 2008 Article en page(s) : p. 139-142 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Color fading' protection' retention' 'Hair color resistance' wash simulation' Résumé : Due to the improved performance of modern hair colorants, the high natural variability in hair qualities and the individual influences of manual product applications, colour care effects of cosmetic treatments are very difficult to detect. A new, highly sensitive test method to study the colour fading behaviour of human hair was established for a large variety of cosmetic treatments. This method is based on an automatic multistage application of standard wool tissues combined with automatic colour evaluation by means of CIE L × a × b × measurements (DIN 5033). The delta E values are the main interest because they include all information regarding the L (black vs. white), a (red-green) and b (blue-yellow) axes defined in the Hunter Lab colour space. For validation of this new method, different permanent and non-permanent hair colour shades were applied to undamaged light brown Caucasian hair strands. The hair strands were washed manually stepwise 30 times and the colour loss compared with the results obtained on wool tissues using an automatic application system. For most of the investigated hair colours, a coefficient of determination of r2 > 0.99 was achieved. Modern permanent hair colours show a high resistance to cosmetic treatments. Over 90% of the initial colour result was retained after 30 product applications. Shampoo and conditioner formulations induce different degrees of colour loss in hair. In basic formulas significant influences of single surfactants could be detected. The new method using wool tissues correlates very well with that using manually washed Caucasian hair strands. This automatic method is very time-effective and offers an excellent reproducibility with a high sensitivity for assessing product influences on artificial hair colours.

Titre : Bring back the steel ? The growth of plastics in automotive applications Type de document : texte imprimé Auteurs : Rose Ann Ryntz, Auteur Année de publication : 2006 Article en page(s) : p. 3-14 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Flow agents' 'Dynamic mechanical properties' Fluorescence Hardness 'Scratch resistance' 'UV spectroscopy' Photodegradation Polyacrylics Isocyanates 'Melamine-formaldehyde resins' Photostabilizers Polyurethanes Solventborne 'UV, EB radiation cure' Waterborne 'Service life prediction' Weatherability Automotive-OEM High-solids Latex PARP Index. décimale : 667.9 Revêtements et enduits Résumé : The development of plastics has evolved from the use of natural materials to the use of chemically modified natural materials and, finally, to completely man-made molecules. Plastics continue to improve, to afford flexibility, high-impact, and strength. In automotive applications, plastics have increased in utilization to comprise approximately 10% of the total vehicle weight. They offer increased ductility, freedom from corrosion, and increased styling capability. Although plastics have had a remarkable impact on our culture, it is obvious that there is a price to be paid for their use. Plastics are almost too good, as they are durable when processed correctly, but easily damaged when utilized in the incorrect application. Plastics also degrade very slowly, making recycling mandatory. And finally, while plastics consume only 4% of the world's oil production (petroleum is the raw material that is chemically altered to form commercial plastics), their cost hinges on the cost of petroleum. As petroleum prices increase, so too will the cost of plastic. In 2004, the higher price of plastic forced many plastic manufacturers out of business, and forced many automotive suppliers to look into alternative replacements. With publications such as USA Today reporting that current oil reserves will only last 40 years, scientists continue to seek cheaper alternatives to plastic. This article summarizes the history of commercial plastic development, with a focus on utilization of the materials in automotive applications. Damage criteria of plastic components, namely scratch, oxidative degradation, and impact, are discussed in relation to coatings and processing robustness. Environmental regulations, particularly in relation to recycling mandates, are explained. And finally, trends in alternative material development, including bioplastics, films, ceramic coatings, and nano-composites, are formulated.
