Description

Fine dust dustproof composition {COMPOSITION FOR ANTI-FINE DUST}

The present disclosure relates to a fine dust dustproof composition.

When dust builds up in your body, your body's immunity is compromised and can cause a variety of conditions, such as heart disease and respiratory problems. Even bronchial stenosis and prolonged inhalation increase the prevalence of asthma and lung disease and early mortality.

The skin acts as a barrier between the organism and the environment in the outermost part of our body, which is in direct contact with dust, which often degrades when directly exposed to pollution. In particular, the fine dust is 20 times smaller than the pores, so it can easily penetrate the skin. In fact, air pollutants such as fine dust have been known to seriously affect skin health. In the short term, premature aging, lack of moisture, fine lines and wrinkles, and irreversible skin damage in the long run can lead to serious illnesses such as skin cancer, as the skin loses its ability to protect itself from environmental factors. .

Therefore, there is a need for a study on cosmetics for isolating dust, which is a harmful substance that is harmful to skin and sometimes fatal to the human body, from dust.

Since fine dust is generally composed of 22% of organic carbon compounds, 8% of carbon elements, 22% of nitrates, 15% of sulfates, 15% of soil crust components, and other 18% (National Institute of Science), It occupies about 30% (organic carbon compound and carbon element), and carbon black having a zeta potential similar to fine dust was selected as a substitute for fine material.

Evaluation: Measure Dust Effect

After the carbon black 1% aqueous solution was evenly applied to the hair tress, the hair tress was completely dried. Thereafter, the dried hair tress was placed in a Petri dish containing 30 g of a commercially available 20% aqueous shampoo of shampoo, rubbed with the same force for 90 seconds, washed in running water, and completely dried to remove carbon black. Compared. The degree of carbon black removal was compared with brightness (L *) (SPECTROPHOTOMETER instrument measurement, CM-2600d, KONICA MINOLTA, INC.).
