sodium lauroamphoacetate sodium lauroamphoacetate sodium lauroamphoacetate is a zwitterionic surfactant of the amphoacetate class. it is used as a very mild cleaning agent originally used in shampoos and body washes for infants but it now sees broader use in other personal care products. sodium lauroamphoacetate names iupac name sodium 2-acetate other names sodium lauroamphocetate; lauroamphoacetate; sodium lauramphoacetate; sodium lauromphoacetate; sodium lauraamphoacetate; sodium lauroamphoacetate; lauroamphoglycinate; lauroamphoglycinate; sodium lauroamphoacetate identifiers cas number 66161-62-4 y 3d model (jsmol) interactive image chemspider 57539164 pubchem cid 71308272 unii slk428451l y comptox dashboard (epa) dtxsid40745448 inchi inchi=1s/c18h34n2o3.na/c1-2-3-4-5-6-7-8-9-10-11-17-19-12-13-20(17,14-15-21)16-18(22)23;/h21h,2-16h2,1h3;/q;+1key: hfqbfcsvhwjvnk-uhfffaoysa-n smiles cccccccccccc1=ncc1(cc()=o)cco. properties chemical formula c18h34n2nao3 molar mass 349.471 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). y verify (what is yn ?) infobox references synthesis sodium lauroamphoacetate is produced in a 2 step process. firstly lauric acid reacts with aminoethylethanolamine (aeea); this initially produces the amide however heating causes this to cyclize to give the imidazoline group. this reacts with 1 equivalent of sodium chloroacetate to give the final product. a reaction with 2 equivalents gives the di-acetate, which is also marketed as di-sodium lauroamphoacetate. safety sodium lauroamphoacetate is exceedingly mild, and cases of skin irritation are rare but not unheard of. it has been proposed that these instances are caused not by sodium lauroamphoacetate itself but rather by failures in quality control which result in it being contaminated with aeea.
