Embodiment

[0128] E.1 Operation of the contamination test chamber

[0129] In order to evaluate the effect of pollution on hair 09, an urban pollution environment simulation device for simulating urban pollution environment was established and operated.

[0130] figure 1 The shown urban pollution environment simulation device of the present invention comprises:

[0131] Diesel engine (1);

[0132] Pollution test chamber (2), its width is 40cm, length (or depth) is 65cm, and height is 140cm, and the chassis of wherein chamber is made of aluminum alloy, and it has four UVA that are installed on each inner side wall of pollution test chamber lamp (3), and wherein placed between the UV lamp and the exhaust gas filling space consists of The UV transparent isolation film (4) that FEP is made avoids waste gas pollution;

[0133] Three rows of hangers (5) made of stainless steel for hair strands are installed horizontally in the middle of the test chamber from the rear wall to the front of...

Abstract

The present invention relates to a city pollution environment simulation apparatus, combining air pollution and UV irradiation in the same test environment. The apparatus comprises an engine (1), a cooling tank (12) and a pollution test chamber (2) that comprises one or more UV lights (3), a temperature / humidity sensor (7), an online gas concentration analyzer (8), a PM2.5 / PM10 analyzer system (9), a gas inlet (17) and a gas outlet (11).

Description

technical field [0001] The present invention relates to a device for testing the effects of environmental pollution and the efficacy of personal care compositions for cosmetic or pharmaceutical use against this effect. In particular, the present invention relates to a device for testing the anti-pollution efficacy of personal care compositions by simulating an urban atmospheric environment, and for studying the damage caused by urban pollution to hair, skin and / or other substrates before and after application of such compositions . Therefore, the effects of such compositions or their individual components on hair and / or skin, or the direct effects of urban air pollution on the compounds themselves are studied. More particularly, the present invention relates to an experimental device for simulating in a laboratory the atmospheric conditions in a city and a method for operating said device to achieve the above-mentioned purpose. Background technique [0002] The rapid urban...
