DMSO 70/30 4 oz. Gel 4 pack Jar -70/30 w/Aloe Vera Super Biologic Non-diluted 99.995% Low Odor Pharma Grade in BPA Free Plastic
Pharma Grade DMSO (Dimethyl Sulfoxide) is a very distinctive dipolar highly aprotic organic solvent with a freezing point of 64 Deg F. DMSO by itself is actually odorless, what makes Dimethyl Sulfoxide smell and taste like onions or garlic is DMS (Dimethyl Sulfide).
Industrial grades of DMSO will contain DMS and therefore give off an offensive odor. Pure Pharma Grade Dimethyl Sulfoxide is distilled and purified to remove DMS and any other contaminants leaving it odorless.
One of the highest concerns surrounding DMSO is that it can take everything through the skin. While DMSO by itself can penetrate fairly easily through the skin and does enhance the adsorption rates of some chemical compounds, it does not have a universal ability to take just anything through the barrier properties of human skin. Despite the past history, Dimethyl Sulfoxide is proven to be a safe versatile material. It should also be understood that when water is present as a cosolvent in DMSO the penetration kinetics are much lower.
DMSO freezes around 64 degrees, this is normal. Place in warm water to thaw, do not use boiling water or put in a microwave. When frozen, the DMSO can look like glass crystals.
