There is an increased pressure towards incorporating biosustainable and biodegradable components in consumer products such as home and personal care products, cosmetics and...

This proposal is aimed at understanding the surface activity of the antibacterial agent, Triclosan, in the presence of surfactants. We request NR beam time on SURF to...

Zwitterionics (here, alkyldimethylammonium carboxybetaines) are widely used in applications which require "mildness", e g cosmetics and isolation of membrane proteins, although...

Tolaasin is a lipodepsipeptide (lipo = hydrophobic side chain, depsipeptide is an amino acid ring closed in a particular way) produced by strains of Pseudomonas tolaasii, and it...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is now emerging as an important structural signature associated with a wide range...

We request NR beam time on SURF to study the impact of multivalent counterions on the surface adsorption of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

Hydrophobins, hfb2, are secreted fungal proteins, which are strongly surface active and possess powerful emulsion and foam stabilising properties. Understanding their...

Many proteins exhibit a lag in lowering the surface tension at the air-water interface. The origin of this lag is not well understood either experimentally or theoretically. The...

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...

This proposal is about the development of sustainable detergency based formulations, based on the blending of biosurfactants and conventional surfactants, and is part of a CASE...

Hydrophobins, hfb2, are secreted fungal proteins in the form of a small lipopeptide. They are strongly surface active and self-assemble in solution and at interfaces. They have...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

The balance of different influences on adsorption such as electrostatic attaction to an interface, repulsion between charged adsorbates and solven interactions provides the rich...

Polymer-surfactant mixtures are extensively used in a wide range of domestic, industrial and technological applications. This proposal is part of a collaboration between Oxford...

Increased environmental pressures and awareness is promoting a major drive towards an increased use of biosurfactants to produce more biosustainable and biodegradable consumer...

In the context of home and personal care products, studying surfactant and mixed surfactant adsorption on model solid surfaces, which mimic real surfaces such as fabrics, hair...

Anti-freeze proteins (AFP¿s) inhibit ice growth through the binding of a predominantly hydrophobic surface on the globular protein to particular crystal planes of ice. AFP¿s are...

The overall objective is to model the amount and composition of adsorbed mixtures of three types of zwitterionic surfactant and two charged surfactants at the silica/water...

Studying surfactant and mixed surfactant adsorption on model solid surfaces, which mimic real surfaces such as fabrics, hair and skin, is starting to provide a real insight into...

This is a new programme of work and a collaboration between CCLRC, Oxford, Unilever and Manchester. It is concerned with polymer aided deposition to solid substrates, using...
