   Sammanfattning : Currently, over 100 high-volume chemicals have been classified as endocrine disrupters. One of these is nonylphenol, which was used as the model compound in this study. This substance originates mainly from the degradation of non-ionic surfactants (nonylphenol ethoxylates) which are widely used in industrial and domestic applications. LÄS MER

3. 2. Properties of stabilizers in colloidal dispersions

   Författare :Catherine Boissier; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surfactants; conformation; polymers; NMR relaxometry; exchange dynamics; residence times; adsorption; polymer-surfactant interaction; NMR diffusometry;

   Sammanfattning : Surfactants and polymers are frequently used as stabilizers in colloidal dispersions. Depending on their solubility and the interactions in their local environment, their tendency to remain adsorbed on a surface will differ. LÄS MER
