Dichlorophenoxychlorophen, commonly known as "triclosan", is normally white or off-white crystalline powder with a slight ph-enol odor. Insoluble in water, soluble in lye and organic solvents. Dichlorophenoxychlorophen is a broad-spectrum antibacterial agent, which is widely used in daily chemicals such as soap and toothpaste. According to current research and guidelines, diclofenac is still considered safe, but many studies on animals and bacteria have shown potential harm to humans. The U.S. Food and Drug Administration and the Canadian government are stepping up their efforts. Scientific research, hope to further understand the impact of diclofenac on the human body. It is widely used as a bactericide against general bacteria, especially against Staphylococcus Streptococcus and Gram-staining bacteria, which has strong bactericidal power, but is relatively weak against fungi. It is usually used in soaps, shampoos, toothpastes, and quasi-drugs.
