When a player picks up a minor knock, sprain or muscle ache during training, applying something cold is a familiar first-aid response. However, carrying ice or preparing a cold pack is not always practical beside a court, pitch or treatment area.
MEDTEC Cool Max Spray 100ml provides a quick and portable way to produce an immediate cooling sensation on the skin.
For customers who previously used the discontinued Walter Ritter Ethylchloride Spray, Cool Max Spray serves the same immediate cooling purpose. It is a different formulation and should be used according to its own label and safety instructions.
Important: Cool Max provides temporary surface cooling. It does not diagnose an injury, repair damaged tissue or confirm that someone is ready to continue playing.
What is MEDTEC Cool Max Spray?

Cool Max Spray is a topical cold spray intended for sports and general first-aid settings.
It may be sprayed around minor sports injuries such as sprains and muscle aches to produce an immediate blast of coolness.
The compact 100ml can makes it convenient for:
- Sports first-aid kits
- Physiotherapy and rehabilitation clinics
- Football, rugby, netball and court-side medical bags
- Coaches and team support staff
- Gyms and training facilities
The ingredients are n-pentane, n-butane and isobutane.
These volatile ingredients evaporate rapidly after spraying, removing heat from the skin surface and creating the cooling sensation.
Cool Max should be described as a cold spray, not as a local anaesthetic.
Why consider MEDTEC Cool Max Spray?
Cool Max Spray offers a practical combination of:
- Immediate surface cooling
- Simple spray application
- Compact 100ml packaging
- Portability for sports and clinical first-aid kits
- No need to prepare ice before application
For clinics, sports teams and customers looking for a replacement after the discontinuation of Walter Ritter Ethylchloride Spray, Cool Max provides the same practical immediate cooling function in its own formulation.
Use it for what it is designed to do: provide brief, localised cooling while the injury is assessed and the appropriate next step is decided.
How to use it safely

Always read the instructions before use.
The current manufacturer information advises users to:
- Shake the can well.
- Hold it at the distance specified on the product label.
- Spray the intended area continuously for no longer than five seconds.
- Stop immediately if the skin becomes excessively cold, painful, numb or unusually discoloured.
- Do not spray on the face or an open wound.
- Follow the label if another application is required.
Do not assume that spraying for longer will provide a better result.
Spraying continuously for more than five seconds may cause frostbite.
Important precautions
Cool Max Spray is an extremely flammable, pressurised aerosol.
Keep it away from:
- Naked flames
- Sparks and ignition sources
- Lit cigarettes
- Hot surfaces
- Direct sunlight
- Temperatures above 50°C
Do not pierce or burn the container, including after it is empty.
Precautions:
- For external use only
- Avoid breathing in the spray
- Avoid direct contact with the eyes
- Do not use on children under 18 months
- Keep out of reach of children
- Stop using it and consult a doctor if a rash develops
Use it in a ventilated area and follow all warnings printed on the can.
Cooling is not an injury assessment
A cold spray may temporarily make an area feel more comfortable, but reduced discomfort does not mean the injury is minor.
Stop activity and arrange an assessment if there is:
- Severe or worsening pain
- Obvious deformity
- Inability to bear weight or use the limb normally
- Rapidly increasing swelling
- Numbness or loss of sensation
- Pain directly over a bone
- A significant collision, fall or twisting injury
- Repeated instability
- Symptoms that persist or worsen
Do not repeatedly spray an injury simply to mask pain and continue playing.
Modern soft-tissue-injury guidance also emphasises protection, education and appropriate progressive loading rather than relying on passive treatments alone.
Cooling may be used for short-term comfort, but it is not the rehabilitation programme.
