5990 Reliwash Redcap Phosphate Buffer Solution acid and alkali eye wash skin wash

Redcap vs Water: Independent test data results confirm 500ml Redcap is more effective than water…

Until now, there has not been a cost-effective medical solution to treat acid and alkali related contamination, so current protocols still recommend the sole use of water. However, independent test data has now confirmed that one bottle of Redcap 500ml is significantly more effective at neutralising acid and alkali splashes than comparable water treatment and is available at a fraction of the cost of other pH neutralising eye washes on the market.

Redcap continues to neutralise acid & alkali pH levels
long after water slows:

In vitro titration studies were independently conducted to assess the effectiveness of Redcap. Reliance Medical identified sulphuric acid (96%), and sodium hydroxide (40%), as the most commonly treated acid and alkali related injuries. 10ml of each substance were pipetted into a conical flask and placed in a magnetic stirrer. Initial pH values were recorded. Redcap was added in progressive increments, with the pH value recorded after each increment. Further test reports on the effectiveness of Redcap are available upon request.



Rinsing with Redcap will help stop and neutralise the harmful pH values of both acids and alkali.  Special care should be taken when treating incidents involving the eyes to ensure all fluids run off the face and do not pool in the ears, nose, or mouth. Redcap is available with either standard caps or eye bath tops to ensure the flow of the solution can be easily controlled and reduce the ‘waterboarding’ effect for patients. It is recommended to use up to 2 litres of Redcap solution, after which you should continue to rinse with standard Reliwash eye wash until the emergency services arrive.

NOTE: All eye related injuries require medical attention.


Redcap is not recommended for the treatment of hydrofluoric acid incidents. Hydrofluoric acid is toxic and highly corrosive to skin and bones. Redcap may have a neutralising effect and help to rinse but will not limit the acids toxic effect. Dedicated hydrofluoric acid treatment kits are available for customers who have a first aid requirement for hydrofluoric acid incidents.
