This webinar was 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 provided an overview of the LGN model and demonstrated its utility by explaining the properties of several commercial cosmetic products.
