摘　　要：7毒性传统表面活性剂,特别是阳离子表面活性剂对水生生物具有很强的毒性。其急性毒性是由于表面活性剂在细胞-水界面处的吸附-离子相互作用现象。降低表面活性剂的cmc通常导致表面活性剂更强的界面吸附,通常导致其急性毒性升高。表面活性剂疏水链的长度增加也导致表面活性剂急性毒性增大。大部分AAS为对人体和环境(特别是对海洋生物)低毒或无毒,使其适合做为食品成分、药物和化妆品[107-113]。很多研究者证明氨基酸表面活性剂对皮肤温和且无刺激[110]。Surfactant use throughout mankind is extensive,from their initial applications as detergents extending to use in medicine,lubricant,cosmetics and even enhanced oil recovery.However,the image of surfactant use has in the past been tarnished by issues with low biodegradability and their synthesis from nonsustainable resources.Amino acidebased surfactants are a class of surfactants derived from a hydrophobe source coupled with simple amino acids,mixed amino acids from synthesis or from protein hydrolysates,and as such can be derived solely from renewable resources.There are several pathways for their synthesis and this allows for extensive structural diversity in this class of surfactants,resulting in widespread tuneable functionality in their physiochemical properties.This review includes the details of most of the available routes of synthesis for amino acid surfactants(AASs) and the impact of the diverse routes on their final physiochemical properties,including solubility,dispersability,toxicity and biodegradability.The diversity offered by the structural variation in AASs offers many exciting commercial opportunities for this ever-growing class of surfactants.It also includes a discussion on current and future potential uses of AASs.
