Patch Testing

One of the final steps in the safety evaluation of new products is to perform a Patch Test on human subjects.  We offer a range of patch tests, expert assessment and certification to ensure your product meets the highest safety specifications before its release onto the market.   

Materials such as toiletries, detergents and other consumer products are tested for their irritancy and/or sensitisation (allergic) potential.


Irritancy responses typically occur immediately and only at the site of exposure. The response tends to be universal (produces a reaction in most individuals) and depends on the strength and duration of exposure.

Sensitisation (allergic)

Sensitisation is the process by which a person becomes, over time, increasingly allergic to a substance through repeated exposure to that substance. It is very different from irritation because it involves immune response, the reaction becomes worse with repeated exposure, and it is usually specific to individuals.
