PRODUCT INTRODUCTION
description
Cobalt bis(2-ethylhexanoate) is a chemical compound of cobalt. Cobalt is a metallic element with the atomic number 27. It is found naturally in rocks, soil, water, plants, and animals. In small amounts cobalt is an essential element for life, as it is part of vitamin B12. However, excess exposure is known to exhibit toxic effects. (L29, L30)
