Natrlquest E30 is a biodegradable chelating agent that is special in the fact that it is very selective towards problematic transition metals such as Cu and Fe compared to Ca and Mg.

This makes it ideal in personal care formulations as it is tackling these problematic transition metals first while in the formulation, but still giving hard water control when released into water. This gives Natrlquest the benefit of excellent anti-oxidant properties and foam preservation in shampoos and conditioners.
