High-polarity solvents:
Our dimethyl sulfoxides (DMSO)
Dimethyl sulfoxide (shortened to DMSO) is an organic compound with the chemical formula of (CH3)2SO. It is a high-polarity industrial solvent that completely dissolves in water and has a high solubility for many organic and non-organic compounds.
Used in agricultural chemicals
DMSO serves as a synthetic solvent for pesticides and herbicides and is also used in water-soluble formulations. It helps active substances penetrate the plant membrane while, at the same time, doing very well in eco-toxicology terms.
Used in the plastics industry
In the plastics industry, dimethyl sulfoxide is used to harden and compact plastics. It can also help improve the colour and clarity of plastics.
Used in the electronics industry
Since dimethyl sulfoxides (DMSO) reduce electrostatic charges, they are also used in production processes, be it for the manufacturing of micro-electronic devices, the production of flat screens or the cleaning of circuit boards, etc.
Used in coating
Our dimethyl sulfoxides are also used for coatings. Here, it is in particular their great dissolution power when it comes to polymers and their low level of toxicity that customers are interested in.
Used in the pharmaceutical industry
In the pharmaceutical industry, dimethyl sulfoxides are used as auxiliary agents: they help to transport active substances via the skin to their site of action. Its use in that industry is based on the very low toxicity of DMSOs.
Used in the paints and varnish industry
In the paints and varnish industry it is above all the degreasing effect of dimethyl sulfoxides (DMSO) that matters. In addition, the substance also improves the clarity of paints and varnishes. Besides, and contrary to nitromethane and dichloromethane, DMSO is also a safe paint stripper.
Used in the production of aromas and fragrances
Dimethyl sulfoxides (DMSO) clean aromatic and fragrant oils by removing low-molecular sulphur compounds and hereby ensure that these oils smell good for a long time without developing unpleasant odours.
Used as versatile cleaning agent and solvent
Dimethyl sulfoxide (DMSO) is a solvent that is commonly used in laboratories and for technical purposes as it can be mixed with water in any ratio. Since it belongs to the group of nucleophile, aprotic, dipolar solvents it can also be mixed with various organic solvents such as alcohols, ketones, carbon acid esters and chlorinated hydrocarbons.
Used in microbiology
In the context of the development of cell cultures, dimethyl sulfoxide (DMSO) is used for cryo-preservation purposes: The substance is slightly more effective than glycerine when it comes to preventing the formation of ice crystals during the freezing process. Ice crystals inside the freezing media can destroy cell organelles and result in cell death.
