Particulate Pollution Test Apparatus
If you want to show how well your product protects hair from particulate pollution, then you may consider performing an anti-pollution test.
Our anti-pollution test for UV and gaseous pollution uses a custom-built chamber that is able to pass a fixed amount of ozone pollution over the surface of the hair. The chamber has a UV-transparent lid, and is placed inside a solar simulator (Q-Sun), to test the combined effects of gaseous pollution and sunlight. In a typical test pollution levels and sunlight levels are exaggerated. The effects of pollution damage can be measured using differential scanning calorimetry and dry combing.
