Practical Aspects of Cosmetic Emulsions under the New Lamellar Gel Network Model

When: May 25, 2021, from 10–11 a.m. CDT (Chicago, USA; UTC-5)
Presenter: Ricardo Diez, adjunct professor at Rutgers, the State University of New Jersey, USA

This webinar is co-sponsored by the Society of Cosmetic Chemists (SCC).

The Lamellar Gel Network (LGN) model can predict and explain key aspects of cosmetic emulsions, from rheology to sensorial attributes and long-term stability. It also offers insights into the delivery of actives from emulsions.

The LGN approach focuses on the physical nature of the network as a whole, as identified by techniques such as XRD, DSC, TGA, and microscopy, rather than on its individual components. It is the result of four decades of developmental effort and represents a significant departure from the Griffin’s HLB model of 1949.

In this webinar Dr. Diez will provide an overview of the LGN model and demonstrate its utility by explaining the properties of several commercial cosmetic products.

High Throughput Formulation of Sustainable Cosmetic and Consumer Products

When: May 27, 2021, from 12–1 p.m. CDT (Chicago, USA; UTC-5)
Presenter: Dr. Samiul Amin, associate professor, Chemical Engineering, Manhattan College

Microbially produced biosurfactants, biodegradable polymers and sustainable ingredients like chitosan and silk proteins are gaining the interest of the home and personal care industry as alternatives to petroleum-derived materials. However, a move to fully sustainable materials will only be successful if performance criteria such as rheology and surface activity match or surpasses that obtained from traditional surfactants and polymers. High throughput formulation automation and advanced characterization techniques provide a route into fast engineering of microstructures and interactions for effective product formulation design. The utility and benefits of this approach will be illustrated for a range of sustainable and biodegradable alternatives and their combinations.

Process Safety Standards are defined as Performance Standards. Performance Standards are written in terms of what is expected to be accomplished or performed.
