1. Surfactants based on natural products - enzymatic synthesis and functional characterization
Sammanfattning : Surfactants are molecules that contain a water-soluble and afat-soluble part. They have important functions in productssuch as detergents, cosmetics, pharmaceuticals and foods aswell as in many industrial processes. Surfactants are used onvery large scale, which makes it important to decrease theirimpact on the environment. LÄS MER
2. Nanoconfined imidazolium ionic liquids
Sammanfattning : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. LÄS MER
3. Polyelectrolyte induced assembly of ionic surfactants
Sammanfattning : .... LÄS MER
4. Allergenic oxidation products in ethoxylated non-ionic surfactants : Chemical characterization and studies on allergenic activity
Sammanfattning : The susceptibility of ethoxylated non-ionic surfactants to oxidation on exposure to air was investigated. Surfactants have a complex chemical composition and are widely used in a variety of applications for to their amphiphilic properties. Ethoxylated non-ionic surfactants are regarded by the producers to be stable at normal handling. LÄS MER
5. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution
Sammanfattning : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. LÄS MER
