| Résumé : |
We report results on the physical phase behavior of sulphonated methyl esters in different water hardness conditions. We also compare its foam performance against a number of other surfactants in correlation with their Krafft points at different levels of water hardness. Whilst SME is slightly behind in terms of solubility in deionized water, it gains ground as the level of water hardness goes up and is significantly better, when certain mixtures are used. The best results are observed at 1:1 ratio for Krafft point as well as for foam performance. The results suggest potential applications for these relatively new palm oil-derived surfactants, namely in regions with high levels of water hardness. |
