New Capability Inverse Liquid Chromatography for Studying Complex Fibre-Liquid Interactions

Lead Research Organisation: Imperial College London
Department Name: Department of Chemical Engineering

Abstract

The interaction between multi-component liquid systems and complex semi-amorphous solids is an industrially important but poorly understood research area. This problem is relevant to how hair,
diapers and clothing products interact with complex aqueous liquid formulations, which usually contain
multiple active species including surfactants, stabilizers, thickeners, fragrance molecules, malodor
species, dyes, preservatives, biological agents and processing aids. This project will use a novel
chromatographic method by which the solid materials of interest (e.g., hair, diaper materials or
consumer fabrics) are packed into a liquid chromatography (LC) column, through which are eluted
complex aqueous based liquid mixtures of relevance. This technique is known as Inverse Liquid
Chromatography and is related to a popular research technique, Inverse Gas Chromatography. Using
appropriate detectors in the LC systems, the extent of selective sorption of the liquid mixture
components can be quantified as well as the kinetics associated with these multi-component sorption
processes. Such novel experimental methods offer unrivalled understanding of these complex solidliquid
interactions under what can described as real world interaction conditions. We would like to
collaborate with Dr. Daryl Williams, the world lead expert in the specific research area to fully leverage
his expertise to develop this leading edge capability for P&G applications. We are expecting to leverage
this project to build more insights into the mechanism of liquid-solid interaction and bring the benefits
of next-generation product innovation to the widest possible community.
