Abstract
The interaction between methyl p-hydroxybenzoate and polysorbate 80 has been determined using a molecular sieve technique. At 25° and at surfactant concentrations of 2·86 and 1·43% respectively, the ratios of total to free preservative were 2·9 and 1·9. These results are comparable with published data.Keywords
