Lipids in Personal Care and Cosmetics
Instructor: Benjamin Schwartz, Customer Innovation Manager, AAK USA Inc.
This course provides a detailed look into plant-based lipids' roles in personal care and cosmetic formulations. Benjamin Schwartz, Customer Innovation Manager at AAK USA Inc., highlights how the structure of fatty acids found in plant-based lipids, and more importantly, the triglycerides and wax esters that contain them, determine the interdependent properties of oxidative stability, compatibility, solid fat content, and crystallization types of various oils, fats, and waxes. You will learn how these properties can inform choices of oils, fats, waxes, and their derivatives within different personal care and cosmetic products, including anhydrous and emulsion-based products.
Beyond Triglycerides: Applications for Unique Plant-based Lipids in Personal Care
Instructor: Benjamin Schwartz, Customer Innovation Manager, AAK USA Inc.
This course provides a deeper look at lesser-known, non-triglyceride lipids and how their unique properties can be used for personal care applications. Benjamin Schwartz, Customer Innovation Manager at AAK USA, explores the chemical properties of tocopherols, sterols, triterpenes, phenols, phospholipids, ceramides, sphingolipids, galactolipids, and waxes. You will learn how the different functional groups of these components produce their chemical properties and, in turn, how those chemical properties can be used to produce specific product performance characteristics.
Design of Lamellar Gel Network Emulsions for Personal Care and Cos¬metics Applications
Instructor: Ricardo Diez, Adjunct Professor, Rutgers University, USA
Lamellar gel network (LGN) emulsions have a unique bilayer microstructure and viscoelastic properties that find broad application in skin care products, cosmetics, hair conditioners, hair dyes, and relaxers.
This course provides a detailed overview of the science and technology of these commercially important materials. You will learn about the LGN model developed by the course instructor, Ricardo Diez, and its use to design key aspects of cosmetic and personal care emulsions, from sensorial properties to stability and scale-up, as well as delivery of actives.
Bonus Presentation: The Use of Plant Proteins in Personal Care Products
Presenter: Dr. Karl Lintner, CEO, KAL'IDEES S.A.S., France
Personal care product manufacturers have a choice of approximately 2,000 substances for product formulation. Plant proteins have gained traction by replacing animal-derived proteins.
This presentation covers best practices for selecting optimal proteinaceous raw materials for various functions and activities (from shampoos and conditioners to facial and body care applications). Dr. Karl Lintner discusses the differences in use and function of native proteins, hydrolyzed proteins, and synthetic peptides. Finally, the complexities of claim substantiation, measuring functions, safety evaluation, and regulatory space are addressed, along with the differences between cosmetic and pharmaceutical practices and domains.
Bonus Presentation: Practical Aspects of Cosmetic Emulsions under the New Lamellar Gel Network Model
Presenter: Ricardo Diez, Adjunct Professor, Rutgers University, USA
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 presentation, Dr. Diez provides an overview of the LGN model and demonstrates its utility by explaining the properties of several commercial cosmetic products.
