Ectoine is derived from Halomonas Elongata, so it is also called "salt-resistant bacteria extract". Under extreme conditions of high salt, high temperature, and high UV radiation, ectoin protects halophiles from harm. Studies have shown that ectoine has a good repair and protection effect on the skin and is one of the bioengineered preparations used in high-grade cosmetics.

Function

Ectoine is a natural compound found in several species of bacteria. It is a compatible solute which serves as a protective substance by acting as an osmolyte and thus helps organisms survive extreme osmotic stress. Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism Ectothiorhodospira halochloris, but has since been found in a wide range of Gram-negative and Gram-positive bacteria. 
Ectoine is used as an active ingredient in skin care and sun protection products. It stabilizes proteins and other cellular structures and protects the skin from stresses like UV irradiation and dryness.
