Abstract

The invention discloses a composition with a function of adsorbing heavy metal. The composition contains hydrogel microspheres with the function of adsorbing the heavy metal. The hydrogel microsphereshave the ability of bonding to the heavy metal on the surface of skin. For the hydrogel microspheres with the function of adsorbing the heavy metal, by mainly combining a hydrogel microsphere material with a metal chelating agent and utilizing dopamine as a bridging substance, hydrogel is bonded to the metal chelating agent through a chemical bond; and by utilizing the heavy metal bonding performance of a larger pore structure of the hydrogel and the chelating agent, the hydrogel microsphere material with the function of adsorbing the heavy metal with good heavy metal removal function is obtained. The cosmetic composition adsorbing the heavy metal is quickly and selectively bonded to the surface of the skin and remove the toxic heavy metal on the surface of the skin when be applied to skin-care cosmetics or drugs, has high selectivity, large adsorption capacity and high adsorption rate and avoids the adverse reaction which occurs by orally taking a toxin expelling drug.

Description

technical field [0001] The invention relates to a composition with the function of adsorbing heavy metals and its application, in particular to a heavy metal adsorption composition containing hydrogel microspheres and its application in cosmetics and skin care products. Background technique [0002] With the rapid development of industrialization, heavy metal pollution has become a social concern. Generally speaking, heavy metal pollution refers to the pollution of heavy metal ions such as lead, mercury, cadmium, and arsenic. Due to the random discharge of industrial wastewater, waste gas, and waste residues, as well as the abuse of agricultural pesticides and fertilizers, a large number of toxic heavy metal ions pollute through water, air, soil, and biological chains to animal and plant products and water sources that human beings rely on for survival. cause potential harm. In addition, in daily life, some daily necessities (glasses, cosmetics, clothing, toys, etc.), mobi...
