The obvious place for First Aid

How Does an Instant Ice Pack Work?

Instant Ice Packs are a convenient and easy to use device used to reduce swelling to injuries often received in sporting activities.

“HypaCool” Instant Ice Packs consist of a sealed plastic outer bag containing a small inner pouch of water and loose Urea crystals.

To activate these components the inner water pouch is squeezed so the Urea crystals are saturated causing an endothermic reaction which allows the pouch to cool to use in first aid to reduce swelling to the traumatised area.

Urea, also known as Carbamide is an organic chemical compound and is essentially the waste produced by the body after metabolizing protein. Naturally, the compound is produced when the liver breaks down protein or amino acids, and ammonia; the kidneys then transfer the urea from the blood to the urine. Extra nitrogen is expelled from the body through urea and because it is extremely soluble.

Synthetic versions of the chemical compound can be created in liquid or solid form, and is often an ingredient found in fertilisers and animal feed.
