laboratory testing

TRI offers a broad variety of analytical techniques to access the functionality of raw materials and finished products on hair.

 

The test information can be used to aid in modifying material composition, enhance end product formulations  and execute research studies. Data from these techniques can be used by customers for claims substantiation. Study plans for testing are generated with the goal of best representing the material or product, on the best suited substrate, using the optimum equipment and method in order to achieve the desired outcome.
