Dimethyl sulfoxide, better known as dimexid (DMSO), is a chemical substance with unusual physical properties. VITATEKA Dimexid 99% 100 ml is a concentrate for preparing a solution for external use. Let us stress the main point right away: this is a chemical, not a food supplement and not a cosmetic, so it must be handled carefully and strictly by the rules.

What this product is

Dimexid 99% is a highly concentrated dimethyl sulfoxide ((CH3)2SO), a clear, essentially colourless liquid. The substance has a curious physical feature: at around +19 °C it crystallises (thickens and forms crystals), and at room temperature of about +22 °C it turns back into a liquid. This is a normal property of DMSO, not a sign of spoilage.

The product is a concentrate: it is not used neat — it is diluted with water before use. It is a technical chemical product for external use only. It is not a medicine, a cosmetic or a food supplement.

Properties and composition

  • Composition: dimethyl sulfoxide 99% (Dimethyl sulfoxide).
  • Volume: 100 ml, a concentrate bottle.
  • Physical state: from a clear liquid to colourless crystals as the temperature drops (below ~+19 °C).

DMSO is known as a strong polar solvent that readily passes through skin. It is precisely because of this ability that the substance must be handled with care: it can carry through the skin whatever is dissolved in it or sits on the skin's surface. For that reason the skin and hands should be clean and the dilution ratios strictly observed. The substance may also have a characteristic sulphur-garlic smell or taste — this is a normal feature of DMSO.

How to handle and use

This is a chemical concentrate, so the handling rules matter more than any «effect». The basic principles of external use:

  • Never use it neat — dimexid must always be diluted.
  • The concentrate is diluted with water in the required ratio (usually 1:3 to 1:10 depending on skin sensitivity).
  • Before first use, do a sensitivity test: apply a little of the diluted solution to a small area of skin.
  • Apply only to clean, intact skin, avoiding open wounds, scratches and irritated areas.
  • Avoid contact with mucous membranes and eyes.
  • For a compress, moisten gauze or cloth with the solution, place it on the skin, cover with a dry cloth if desired; keep it on for about 20–30 minutes, then remove and rinse the skin with water.
  • Use only as intended and at the recommended concentrations, without exceeding them.

Who may find it interesting

Those who work deliberately with DMSO as a solvent for external preparations and home cosmetics and who understand the rules for handling chemicals safely. This is a niche product «for those in the know», not an everyday item. If you are considering dimexid for any medical purpose, that is a question for a doctor or pharmacist, not the subject of this article.

Important safety precautions

  • This is a chemical substance — handle it carefully and keep it away from food.
  • For external use only. Do not take internally.
  • Never use it undiluted.
  • Avoid contact with mucous membranes and eyes; if contact occurs, rinse with plenty of water.
  • A sensitivity test is mandatory; do not apply to damaged skin or open wounds.
  • Individual intolerance, irritation, a feeling of warmth or burning is possible — in that case rinse the solution off and stop using it.
  • Pregnant or breastfeeding women and children should not use it without consulting a specialist; keep out of the reach of children.
  • If medical help is needed, show the product packaging or label if possible.

Storage and disposal

Store in tightly closed original packaging, out of the reach of children, away from food. Below ~+19 °C the concentrate may crystallise — at room temperature it will turn back into a liquid, which does not affect its properties. Dispose of the contents and/or packaging through the separate-collection system in your town.
