On Tuesday, Nov. 8th, 4 P.M. (Berlin time), Dr. Arnold Uhl, Sales & Marketing Manager at LUM GmbH, Berlin, talked about "STEP-Technology for Particle Sizing of Raw Material for Cosmetic Products “ in his COSSMA Webinar. This webinar was sponsored by LUM GmbH.
The webinar was targeted at formulators and product developers, product and quality control managers in cosmetics, home and personal care industries. R&D people in cosmetic and related industries are under pressure to develop, test and market new formulations in periods, much shorter than the product shelf life itself.
The composition of cosmetics, home and personal care products is often characterized by many ingredients of manifold nature. In sun care products for example a moisturizing lotion with Titanium dioxide (o/w) contains 14 ingredients.
The determination of particle size distributions of individual ingredients allows for the early detection of deviations in the raw material, prior to their subsequent use in formulation.
The advantages of the innovative STEP-technology for the characterization of physical separation stability of complex final cosmetic products and the concept of comparative shelf life prediction (ISO/TR 13097) were discussed in a previous webinar. STEP = Space and Time resolved measurement of Extinction Profiles simultaneously for the whole sample, for the entire height of a sample from top to bottom.
Now, the parallel use of this technology for the determination of droplet size distributions and particle size distributions according to ISO 13318 is in the focus of the present webinar. Based on a direct physical measurement true raw data are obtained, the same principle is applied for nanometers up to micrometers. Examples illustrate the easy use.
