TFS favourite’s science paper this month!



Dr. Roger L McMullen and his team at Ashland explored how different types of cationic guar interacts with hair. Several cationic guar variants with different Molecular Weights (MW) and Charge Densities (CD) were studied.

Dr. McMullen collected enterokinetic permeability data using streaming potential and studied conditioning on hair by combing analysis. The results indicate that MW influences the thickness of the deposited guar layer while higher CD determines conditioning by reducing the combing force. The study additionally took on another layer and investigated cationic guar behaviour on different types of hair.

Congrats Roger and the team for such educational and insightful study! We enjoy working with Ashland’s cationic guars at TFS.
