title: [Toxicological characteristics of disodium salt of N-lauroyl-L-glutamic acid--a surface-active agent used in the food processing industry].
abstract: To synthesize the disodium salt of N-lauroyl-L-glutamic acid (LG-Na2), use was made of the chloranhydride method with some modifications. The yield of the product was 85%. LG-Na2 possesses good surface-active properties and an emulsifying effect. The critical concentration of micelloformation of LG-Na2 is 6 10(-3) mol/l. LG-Na2 is a non-toxic compound. It is not cumulated in the animals' body. The LD50 for albino rats per os exceeds 10 000 mg/kg, that for mice 6500 mg/kg. It was shown in subacute experiments in rats that LG-Na2 did not produce any substantial influence on the animals' status or on some biochemical and morphological indicators of blood and organs. The authors suggest a tentative level of a safe oral action of LG-Na2 on man (10 mg per kg bw/day). LG-Na2 is likely to be widely used in food industry.
