Micellar structure and micellar inner polarity of octaethylene glycol n-alkyl ethers

Abstract
The effects of the alkyl chain length of non-ionic surfactants on micellar structure and micellar inner polarity have been investigated. The aggregation number increases while the degree of hydration decreases with increased alkyl chain length. Also, a decrease in micellar inner polarity is found to occur as the alkyl chain length increases. An interpretation of these results is given.
