Abstract

Abstractw The extract of an Acacia Concinna pericarp is rich with surfactant properties. At a concentration of 4.4 × 10−4 M its monomer aggregates to form micelles, which are far below the CMC point of most of the synthetic surfactants. The surfactant contains one replaceable proton in its structure. Its dual nature, make it compatible to interact with cationic and anionic dyes. The ion pair formation is prominent from the shift of λmax of Eosin Yellow (EY) from 517 to 535 nm. Whereas, the hyperchromic shift was observed with Methylene Blue (MB). The self-degradation was observed in ambient temperature and in the dark both in aerobic and anaerobic conditions. Based on its behavior and degradation properties, the proposed natural surfactant is a cheap and good alternative to the synthetic surfactants.
