- the present invention relates to a system for analyzing fine dust blocking ability of cosmetics using an environmental composition device.
- Fine dust is a very small substance that is invisible to us, and refers to a substance with a diameter of 10 ⁇ m (1 millionth of a million) or less that floats or scatters in the air for a long time. Fine dust having a diameter of 10 ⁇ m or less is further divided into ultra fine dust having a diameter of 2.5 ⁇ m or less (1/30 of the hair diameter). Fine dust is most often filtered out of the nose, but ultrafine dust is not filtered out of the nose or airway when breathing, but can be adsorbed through the bronchus into the lungs or deeply penetrated into the pores of the skin.
- Such fine dust is a combination of fine dust (30-50%) from China caused by fossil fuel used in industry and pollutants (50-70%) generated from automobiles, factories and homes. It contains heavy metals such as lead, which not only causes lung disease, but when exposed to ultra-fine dust, immunity decreases rapidly, and various diseases such as cardiovascular, skin, and eye diseases, as well as respiratory diseases such as colds, asthma, and bronchitis. It is easy to get caught.
- ultra fine dust or high concentration of fine dust adheres well to the skin and penetrates into the pores, causing trouble or harmful substances may cause severe skin irritation. Therefore, in order to lead a healthy life in a comfortable living environment, there is a need for a method for protecting the skin from fine dust such as pollutants floating in the air.
