Sammanfattning : This research project concerns investigations of ester-containing cationic gemini surfactants (esterquat and betaine ester types). These dimeric surfactants are compared with their monomeric counterparts. LÄS MER
Sammanfattning : Double tailed cationic surfactants are the active component in softeners. In the beginning of the 90s the active component in softener formulations was changed from a hydrolytically stable dialkyl dimethyl ammonium chloride (dialkyl quat) to a cleavable and biodegradable product containing ester groups in the alkyl chains (dialkyl ester quat).

4. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates
Sammanfattning : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. LÄS MER
5. NMR Diffusion Studies of Association in Surfactant Systems Inclusion Complexes, Micellar Solutions and Microemulsions
Sammanfattning : The aim of this thesis has been to investigate self-diffusion behavior of host-guest complex, microemulsion and polymer solution. Pulsed Field Gradient NMR (PFG-NMR) was shown to provide detailed molecular information in all system studied. LÄS MER
