It cant discolor potassium permanganate at normal temperature. Strong oxidizer can oxidize methyl sulfonyl methane into methylsulfonic acid. Methyl sulfonyl methane solution presents neutral. Microsublimation occurs at 25 c, and speeds up at 60c. It should be store in a tightly sealed container away from heat and direct light, and in a cool dry place. application: msm is a nutriceutical that has proven to be excellent for the skin and for pain relief. Msm speeds the recovery from exhaustion and over-training, and facilitates the repair of protein tissue through its bioavailable sulfur.materials for organic synthesis, high temperature flux, analytical reagent, chromatogram fixing agent, food additive and health care products & medicine, which are used for keep the balance of sulfur element in human body. Msm can be founded in our skin, hair & nail. It can strengthen blood circulation, help hair and nail grow, remove toxin in the stomach and intestine and prevent ulcer etc.also used in curing arthritis and stomachache etc.it is named as minerals of natural beautification. methylsulfonylmethane, %: 99.9 minimumdmso, %: 0.01maxmumappearance: white, crystallineodor: odorlessmesh size (u.s.

It is colorless, odorless and transparent liquid at room temperature. It is a kind of moisture absorption combustible liquid. It has characteristics of high polarity, high boiling point, non-proton, mixed with water, low toxicity and good heat stability. It is soluble in ethanol, propanol, benzol, chloroform and many organic matters. It was known as omnipotent solventdimethyl sulfoxide (dmso) can be widely used as solvent and reaction reagent, especially as processing solvent and laddering solvent in the acrylonitrile polymerization reaction, and synthetic solvent and laddering solvent for polyurethane, also for polyamide, polyimide, polysulfone resin, aromatic hydrocarbon, butadiene and chlorofluoroaniline etc. moreover, dimethyl sulfoxide (dmso) has the functions of anti-inflammatory analgesic, diuresis and mitigation. It is added in dugs as analgesia ingredient. It also known as omnipotent drugii.
