N-Lauroylsarcosine, Na-salt (30 % solution)

Sarcosyl surfactants can be considered as modified fatty acids, where the hydrocarbon chain is interrupted by an amidomethyl (-CONCH3-) group. The structure is similar to soaps, but due to the sarcosyl group, they show a better solubility in water and no sensitivity to calcium ions. The lauric acid in our product is of plant origin.

In biotechnology, N-Lauroylsarcosinate is mainly used for the isolation and characterization of DNA, proteins and enzymes, and for tissue homogenization. Diluted solutions of N-lauroylsarcosinate show at acid pH bacteriostatic properties.
