DMSO 500ml of Super Pure synthesis grade DMSO ( Dimethyl Sulfoxide )
DMSO is generally given a expiry or retest date of 2 years from opening.
Pure DMSO has a freezing point of 18.5 degrees Celcius so in the winter and on cool days in the summer it tends to be solid. This is perfectly normal and one of the ways you can tell it is pure.
If you leave somewhere warm it will slowly melt and return to liquid. If you intend to dilute it with water it will remain liquid at temperatures above o degree Celcius. When it freezes in plastic, you may get some contraction of the bottle it is in. This is normal.
Supplied in a glass bottle.
This has a purity of above 99.9% and is manufactured to an exacting quality standard for the synthesis of Active Pharmaceutical Ingredients ( API ) It is one of the purest forms of DMSO available and should not to be confused with cheaper Industrial grades.

Customer reviews
DMSO is not an instant miracle cure Verified Purchase
I like that I'm still hopeful that dmso will help some of my ailments given time.
I like the Value 500ml Size.
I like that it "freezes" completely, so is probably pure dmso and free of water and contaminants.
I like the simple usage Instructions and Warnings available on the drmyhill site.
I liked the eco-friendly pre-used packaging.
I liked it was exceedingly well wrapped against accidental damage.
My own personal advisory:
DMSO is a strong solvent which will rapidly Strip the Lacquer or Varnish off you Furniture if a Drop is spilled inadvertently.
Therefore Don't lean the Bottle on a Table or Dresser, you will get a Ring. Protect with Cling Film seems impervious.

High quality DMSO Verified Purchase
Excellent purity and appropriately supplied in a glass bottle. It crystallises in cold weather, which is characteristic of high-grade DMSO. The service from Dr Myhill’s shop was superb. I’ve purchased before and will happily do so again. Highly recommended.

Excellent quality DMSO Verified Purchase
This is high quality DMSO. It arrived crystalized which is a good sign of its purity. It became liquid after being left at room temperature. Product has many uses and is a good addition to my medicine cupboard.
