Properties studies of different amino acid surfactant and Sodium laureth sulfate.The results show that,The foam volume was tested by the Ross-Miles foam analyzer refer to the national standard shampoo GBT29679-2013,the overall foam height of amino acid surfactant is similar to that of Sodium laureth sulfate.The compatibility was tested using the MTT method.Amino acid Surfactant are milder than sodium laureth sulfate,Sodium lauroyl sarcosinate milder than sodium laureth sulfate 1.8Times.Disodium cocoyl glutamate milder than sodium laureth sulfate 7.5Times.The thickening effect was tested.When the ratio of amino acid surfactant and Cocamidopropyl betaine is 1∶1,it is still difficult to thicken.
