MEL (Mannosylerthritol Liquid)

MEL (Mannosylerthritol liquid) Characteristics A biosulfactant, one of glycolipids, produced from plant oil by yeast (Pseudozyma sp.) Hydrophilic part : mannose and erythritol Hydrophobic part : fatty acid An eco-friendly and human-suitable material Non-toxicity High biodegradability High surface activity High emulsification activity High thermal stability Low CMC value Properties of MEL(SY16) Surface activity Minimum surface tension(dyne/cm) : 29 CMC1 : 10mg/l HLB : 6~7 Emulsification activity(unit)2 : 70 Stability pH stability3 : 4-10 Thermal stability3 : Up to 100°C Salt(NaCl) resistance4 : Up to 100mM(0.6%) Other properties Toxicity(g/l, w/w)5 : 5 1. CMC value was measured with purified biosurfactant2. Emulsification activity was measured against hydrocarbons with crude biosurfactant at a concentration of 0.1g/l3. Stabilities were determined by measuring the surface tension of biosurfactant solution4. Salt resistance were determined by measuring emulsification activity5. Toxicity was determined as the concentration to inhibit the 50% of mouse fibroblast cell L929
