EPSRC supported EngD: Methods to Study Hydration of Gums in Toothpaste


School of Chemical Engineering

, Friday, October 30, 2020 Competition Funded PhD Project (European/UK Students Only)

About the Project

Hydrocolloids are a critical component in the formation of toothpaste structure. Variations in hydrocolloid raw materials, processing, and interaction with other ingredients in a toothpaste formulation will impact subsequent macro factors including rheology, appearance, mouthfeel, active, flavor delivery and shelf life stability of the product.

Colgate would like to increase our knowledge of how hydrocolloid identity, raw material variation, excipient identity and processing can impact the macro factors of novel formulations. We would like to work with an EngD student to develop a deep understanding of the factors which drive formula robustness in these unique toothpastes. At the end of their EngD they should deliver generalizable conclusions to Colgate which will serve as a toolkit for our formulation scientists going forward, as well as contribute solutions to any on-going challenges. Development of new methods to study these effects will be encouraged as part of the student’s research and is an area for publication

The student will need to work on chemical reactions and also carry this to product scale up on a production scale. The student will gain product development and plant scale engineering experience. While hydrocolloid research has been conducted for toothpaste, these new systems are unique to Colgate.

To be eligible for EPSRC funding candidates must have at least a 2(1) in an Engineering or Scientific discipline or a 2(2) plus MSc. Please email your c.v. to . For details on the Engineering Doctorate scheme visit the homepage. Deadline October 30th
