Formulating polymer solutions to stabilise polymeric foams
Polyurethane foams (PUFs) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agent... -
Competitive interactions in polymer-particle-surfactant blends
Many formulations comprise distinct chemical species that exhibit antagonistic or synergistic interactions that result in unpredictable behaviour. Previous work from our group... -
Effect of drug on the micelles formed by ionic surfactants
The aim of the study is to use SANS in combination with contrast variation to determine the effect of solubilising the lipophilic drug, testosterone propionate, in micelles... -
Extreme Synergistic mixing in Biosurfactant ionic surfactant mixtures
The biobased economy growing substantially and pressure to reduce reliance on palm and crude oil derived materials, demand that Home and Personal Care industries develops... -
Interfacial Adsorption of Soluble Amino-Acid Based Surfactants in Mixtures wi...
Amino acid based surfactants have been known for many years, but so far few detailed studies have been carried out on their properties. We are using amino acids extracted from... -
Multilayer formation at the air-water interface in polyamine / surfactant mix...
The spontaneous formation of multilayer structures at interfaces by surfactant self-assembly is emerging as an important and more common structural signature associated with a... -
Structure of Cellulose Nanofibril Gels with Alcohols
Our group has been working partially oxidized cellulose nanofibrils which form gels in aqueous formulations. Recently we have observed that these fibrils also gel when dialysed... -
Molecular architecture of vesicles formed by novel sterol-modified phospholipids
A family of sterol-modified glycerophospholipids (SML) have been synthesized in which the sn-1 or sn-2 position is covalently attached to cholesterol and the alternative... -
Ibuprofen containing surfactant monolayers: location and stiochiometry of ibu...
An increasing number of potential drug molecules are extremely water insoluble, limiting their commercialisation as medicines. Solubilisation of drug in surfactant micelles is a... -
Interfacial conformation of antibody and antigen binding capacity
Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element... -
Determination of the absorbed amount and location of a hydrophobic drug in su...
Many drugs are both poorly water-soluble (hydrophobic) and lipophilic in nature and are therefore incorporated into surfactant micelles and monolayers. As the incorporation of... -
How perfume structure affects surface coadsorption with anionic surfactants
In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular... -
Ion mediated surfactant adsorption on cellulose films
In recent work with Unilever we have been investigating the structure of gels formed by partially oxidised cellulose nanofibrils for use in sustainable personal care products.... -
Understanding the nature of perfume / surfactant interactions at interfaces
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
Structure of Cellulose Nanofibril Gels
This proposal is part of a new project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils with small amounts of salt or... -
Effect of surfactant head group on micelle structure of drug containing micelles
The aim of the current project is to probe (at the nanometer length scale) the relationship between the solution structures of a surfactant molecule, the aggregate(s) it forms... -
Probing the structure of polymer stabilised foams
Polyurethane foams (PUFs) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agent... -
On the peculiarities of the structure of particle stabilised foam
Many formulated products pass through or end up as foams, comprising immiscible millimeter sized bubbles dispersed into an aqueous continuous phase. Frequently, surfactants or... -
Resolving the enigma of self-assembled meso-structures in an H-bonding rich m...
In a recent successful LOQ experiment (RB 1810629), we have unexpectedly observed possible multilayer stacking of sodium dodecyl sulfate (SDS; ~2wt%) bilayers in glycerol... -
Using polymer / surfactant mixtures to optimise / enhance perfume delivery to...
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled...
