DMSO 99.9% (Ph.Eur.) 250ml

1. Skin reactions : DMSO may cause irritation or allergic reactions upon direct skin contact. It is recommended to do a skin test before use.
2. Odor : DMSO has a characteristic garlic-like smell. This smell can also be detected in the breath when applied to the skin.
3. Interactions : DMSO can affect the properties of other substances it is mixed with. Therefore, you should find out about possible interactions before combining it with other substances.
4. Advice : Before using DMSO therapeutically, you should always consult a health professional and discuss the intended use in detail.
5. Freezing point : DMSO has a relatively high freezing point of around 18.5°C, meaning that it solidifies at temperatures below this value. So it is possible that DMSO solidifies at cooler room temperatures or in a cool basement. If your DMSO crystallizes or freezes, heating it to a temperature above 18.5°C can return it to its liquid state without changing its properties.

The fact that DMSO arrives frozen and thus solid, especially in colder months, is completely normal and no cause for concern. So please don't be surprised if you buy DMSO from us: The fact that the substance freezes is due to its characteristic melting point of +18 °C. Below this temperature, dimethyl sulfoxide crystallizes. For comparison: Water freezes at 0 degrees, so it is still liquid in a cold environment just above that, DMSO, on the other hand, becomes solid before that. In this case, simply place the bottle next to a heater, after a certain time you can already observe how the DMSO slowly becomes liquid again. If DMSO is mixed with water (it can be mixed in any ratio), the freezing point drops.

You buy DMSO from us exclusively in amber glass bottles. There is a reason for this: dimethyl sulfoxide is a polar solvent that can dissolve various plastics and extract substances from them. There are only a few plastics that are compatible with DMSO. These include polyethylene (PE for short), polypropylene (PP for short), polyoxymethylene (POM for short) and rubber/caoutchouc. Our spray attachments are also made of HDPE, a special variant of polyethylene, and POM. The pipettes have an HDPE cap with a rubber cap. All of those plastics are compatible with DMSO and are therefore suitable as sealing material. In general, you can also purchase empty replacement bottles and accessories from us.
