USES: High temperature
solvent and feedstock for organic synthesis, analytical reagent, used in the
production of food additives and health-care products. With 33% sulfur by
weight, MSM is one of the richest sources of organic sulfur, an important
building block of proteins. MSM promotes hair and nail growth, softens the skin
and can help decrease the pain and inflammation associated with arthritis and
joint conditions. MSM is know as"Nature's Beautifying Mineral".
Storage: Sealed and protected form moisture, fire and sunshine.
