TitleTitle:- Making “light” work of Cosmetics Testing
Abstract
I will present the latest developments in the use of near-infrared light to measure the stability of emulsions, suspensions, dispersions, and foams with NO sample preparation. Reducing testing times by 50 – 200x ensures that formulation work can be significantly reduced, whilst ensuring an excellent shelf-life. The new TSi (Turbiscan® Stability Index) provides instant one-click comparisons between samples, allowing the rapid screening of new raw materials.Real world examples will be given including product / packaging interactions, as well as the determination of the foamability of different products.
Biography:
I studied Chemistry at Nottingham University and worked in research and development for 7 years, before moving to technical sales. I have an expertise in using light to measure concentrated systems in both the laboratory and process environments.
ment of the stability of cosmetic products, but it does not aim to specify conditions, parameters of criteria of stability testing [1]. This talk discusses the use of analytical instruments based on the patented optical STEP-Technology® for the direct in-situ characterization of the physical destabilization of cosmetic products. A recently introduced new instrument determines phase separation in emulsions, suspensions, supoemulsions at gravity in real-time, in the very large temperature range from +4 to +80 °C.
Temperature ramps from hot air oven storage tests can directly be copied. The changes in the sample are characterized earlier cp. faster by the instrument than by naked eye. ISO/TR 13097:2013 (Guidelines for the characterization of dispersion stability) suggest instrumental methods for accelerated stability testing to solve the challenge of detecting rather very slow realtime changes in cosmetic products in a short analysis time to allow for fast development cycles.
Another instrument line combines the selected constant temperature (or a ramp) and the physical acceleration. Here, the comparative shelf-life analysis of formulations in original concentration
according t o ISO/TR 13097 is permitted within a short time.

Biography
Arnold Uhl studied chemistry at Humboldt-University in Berlin from 1989-1994, being particularly interested in organic photochemistry. After the diploma he worked for few years in the field of
semiconductor research. He received his PhD in chemistry from Humboldt-University in 2001. From 1999-2004 he worked in a company producing instruments for industrial process control and
scientific research. In 2004 Dr. Arnold Uhl joined the marketing and sales department of LUM GmbH and was appointed Sales & Marketing Manager in 2009. The comprehensive understanding of
complex industrial formulations and processes in an easy way, by using analytical instruments, inspires him during his daily work with customers around the world. In December 2015 he was
appointed member of the board of directors of LUM (Changzhou) Instruments Co., Ltd. and in 2019 member of the board of directors of LUM (Jiangsu) Instruments Co., Ltd.
