The process of history can be interpreted from different angles. One important angle is the application of minerals. Human transformation of the natural environment begins with the domestication of animals and plants. However, as civilization moves from the natural economy to the stage of urbanization and commodity production and trade, the focus of human transformation has also shifted to the application of minerals, while talc, a soft ore, can be used for care, beauty, and even medicines or food. The book "The 50 Minerals of Changing Historical Processes" by the famous British science writer Eric Charing lists talcum powder as one of the 50 minerals that changed the course of history. In reviewing this period of history, the book mentions: "At the end of the 19th century, the fate of the children of the working class was mostly tragic. The poor sanitation, crowded living environment and infectious diseases caused by unclean drinking water were the majority of children. The cause of death, diaper rash is a specific manifestation of low infant hygiene standards, and skin infections caused by diaper rash can cause serious complications, but there is no effective treatment." In 1894, a pharmaceutical company in the United States researched and developed the world's first baby-specific product, a talcum powder containing talcum powder as the main ingredient. This innovation changed the above situation and effectively reduced the incidence of diaper rash in infants. rate. Eckley Charing commented on the advent of this product, "The emergence of baby-specific products shows that the attitude of the society to take care of babies has changed dramatically." The advent of talcum powder with talcum powder as the main ingredient has not only become a force to reduce the high mortality rate of infants, but more importantly, it has turned the care of babies into a social group to think and solve problems for the first time. Looking back over the past 100 years of history, due to the transformation of society, the impact of the new and old economic civilization, baby care products are also upgraded according to the needs of mothers, good baby care products can help parents better care for babies. Talc is such a representative ingredient that is stable, mild, non-irritating and soft, helping new parents care for baby's skin. If you ask a mother at random, have you used talcum powder for your child? I believe that the majority of mothers' answers are yes. The main ingredient of talcum powder is talcum powder, which not only absorbs sweat and oil, but also refreshes the skin. It also helps to relieve itching, reduce the incidence of lice and keep the skin comfortable. The talcum powder is widely used, in addition to being a main ingredient of children's talcum powder, it provides soft and comfortable care for the baby, and is also used in cosmetics and daily necessities, such as foundation, eye shadow, chewing gum, etc., which has become indispensable for people's lives. portion. Its softness stems from its unique sheet-like crystal structure, which reduces the frictional resistance between particles. The surface of this flaky crystal structure of talc is hydrophobic, but the edges of the structure are hydrophilic. Due to the close correlation between talcum powder and life, the relevant misunderstanding needs to be clarified. 1. How is the safety of talcum powder questioned? This is because in the natural environment, some talc mines and asbestos mines are mostly associated or symbiotic. Some industrial talcum powder materials with insufficient purity are easily mixed into asbestos. Asbestos is a known carcinogen, which leads to two People are often compared. This may sound dangerous, is our daily necessities safe? This is the second question we have to answer. 2. What is a safe cosmetic grade talcum powder? Asbestos-free talcum powder is a good talcum powder. In the 1960s, regulators including the United States and the United Kingdom have recognized and successively introduced corresponding strict testing standards. For talcum powder for cosmetics, there is an important indicator that “no asbestos can be detectedâ€. Than medicinal talcum powder. For example, in China's cosmetics testing standards, it is clearly stipulated that asbestos should not be detected in cosmetic ingredients. In order to make consumers more reassured, multi-national regulatory agencies and third-party testing agencies have long observed the safety of talcum powder application. The long-term record of talcum powder for cosmetics is used to confirm the safety of talcum powder, and dozens of medical experts around the world Scientific research and clinical evidence from the past have also supported the safety of talc for cosmetics. For example, publicly available information indicates that the US Food and Drug Administration (FDA), the National Cancer Institute (NCI), and the Cosmetics Review Board (CIR) of the United States have concluded that there is insufficient evidence to prove that talc is Related to ovarian cancer. The responsibility of the US Centers for Disease Control and Prevention is to identify potential risk factors for the disease. The center has never identified talc as a potential risk factor for ovarian cancer. The Harvard School of Public Health's longest observation period of 20 years included 221,866 prospective cohort studies, with authoritative scientific data demonstrating no association between talc and ovarian cancer. With more than 100 years of extensive application, the rigorous testing and monitoring of national regulatory agencies has fully proved the safety of talcum powder, while cosmetic grade talcum powder is a high-quality, high-purity cosmetic raw material that is strictly tested, so as long as it is purchased from regular channels. The qualified products produced by regular manufacturers can be used with peace of mind. The talcum powder, which has changed the course of history, should continue to play its irreplaceable role in life. Source : Network, if there is any infringement, please contact
