| Abstract | ||||
| TWO NONIONIC surfactants named sunflower and cotton seed oil ….. were prepared from sodium salt of sulphonated oils (Part I) by ethoxylation with ethylene oxide. The yield of nonionic surfactants obtained were 70% and 68%, respectively. The hydrophilic-lipophilic balance (HLB), surface tension, interfacial tension, microanalysis, wetting and foaming power were evaluated. Concerning the microanalysis of the prepared surfactants, the results are in a good agreement with theoretical values which confirm the proposed structures. High performance surface activity properties were achieved. The importance of these eco-friendly products are due to an environmental and economical points of view. The prepared surfactants showed more than 88% degradation after 21 days that can be considered agreat success for environment. | ||||
