The influence of hydrophobic-block length on solubilisation capacity was examined for micelles of E(m)B(n) copolymers (E=oxyethylene, B=oxybutylene, subscripts denote number-average block lengths in repeat units) with B-block lengths in the range of 30-76 and with E-blocks of sufficient length to

Prevention of Pseudomonas aeruginosa binding to soft-contact lenses (SCLs) may curtail sight-threatening microbial keratitis. Substrate surface wettability is known to modulate adhesion of P. aeruginosa. This study investigates the use of aqueous alkoxylate block co-polymer surfactants for enhanced wettability and

10 aryl propylene oxides and 6 aryl butylene oxides were synthesized. Dose-mutagenicity relationships were studied for these compounds and for 1,2-epoxybutane, using both the preincubation and plate incorporation Ames tests with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were
