【 摘 要 】

The development of green surfactants produced from renewable raw materials at the expense of petrochemical-based surfactants took into account the increasing requirements for environmental protection and the demand of the society for sustainable development. A variety of renewable raw materials such as triglycerides, carbohydrates or amino acids are used in green surfactant synthesis. The natural structure of green surfactants induces low toxicity and high biodegradability. In this work was investigated the behaviour of surfactant systems containing synthesized amino acid-based surfactants (sodium lauroy lglycinate and sodium lauroyl sarcosinate) and amphoteric or nonionic surfactants, highlighting the differences between surfactant systems containing sodium lauroyl glycinate or sodium lauroyl sarcosinate due to nitrogen methylation of the amide nitrogen in the latter. Synergetic behaviour of aqueous surfactant systems were found, leading to improved properties in terms of surface tension and foaming power.
