Cytotoxicity tests suggested no toxicity for BDO up to 500 μg/mL, and BDO significantly enhanced skin cell migration, indicating potential for skin repair.

The micellization and adsorption properties of TMB were investigated by conductometry, tensiometry, and spectrofluorimetry. A confirmation of the <i>cmc</i> estimated by these techniques has also been obtained by a method suggested by the Moulik group (Basu Ray et al. 2006), which remained almost overlooked, based on the UV absorption of pyrene.

Results demonstrate distinctive features of the two hydrocarbon chains of TMB in contrast to the previous report.
