In modern life, titanium dioxide powder, TiO₂), as an important chemical component, is widely used in many daily products. It is not only the basic raw material for making paints, plastics, cosmetics and other commodities, but also exists in many common products in our daily life, such as skin care products, food, medicines and so on. With the continuous improvement of people's health awareness, the safety of titanium dioxide powder has gradually attracted public attention. So, is titanium dioxide powder safe for human body? Will its use pose a potential threat to our health?
According to the standards of the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC), titanium dioxide powder itself is non-toxic. It is generally considered as a low-toxic substance, which will not cause harm to human body under normal circumstances. Although some studies show that titanium dioxide powder dust may have certain effects on the lungs if inhaled, this effect usually occurs under long-term and high-concentration exposure. For ordinary consumers, there is basically no need to worry about the threat to health when using cosmetics, foods, paints and other products containing titanium dioxide powder in daily life.
At present, the International Agency for Research on Cancer (IARC) lists titanium dioxide powder as a "Class 2B possible carcinogen", which means it may cause cancer to human body, but this risk will only appear under long-term and high-concentration exposure. For ordinary consumers, the content of titanium dioxide powder used in daily life is far below the dangerous level, so it can be considered safe to use in daily life.
For people who have been exposed to titanium dioxide powder for a long time in industrial environment (such as titania tio2 production workers), inhaling too much titanium dioxide powder dust may cause irritation to the lungs, leading to pneumoconiosis or other respiratory diseases. Therefore, it is very important to take strict safety protection measures in the production of titanium dioxide powder.
However, for ordinary consumers, the concentration of titania tio2 exposed in daily life is far below the level of these occupational exposures, so there is no need to worry about the negative impact on health.
For individuals with sensitive skin, cosmetics containing ti02 powder may cause mild allergic reactions, especially if the skin is damaged or used excessively. However, this situation is relatively rare, and most people will not feel any discomfort when using cosmetics and skin care products containing titanium dioxide powder. As an insoluble substance, titanium dioxide powder is usually not absorbed by the skin, so it has no obvious harm to the skin under normal use.
In the field of food, tinox tio2 as a food additive, has been approved by many food safety agencies. For example, both the US Food and Drug Administration (FDA) and the European Food Safety Agency (EFSA) believe that moderate intake of titanium dioxide powder is safe. Nevertheless, in recent years, there have been some discussions about the potential health effects of titanium dioxide powder in food. Some studies have pointed out that long-term large intake may have an impact on intestinal health, but most of these studies are based on laboratory animal research, and there is not enough evidence to show that tinox tio2 poses a threat to human health at normal intake.
The impact of titanium dioxide powder on the environment is relatively small, because it usually does not accumulate in the natural environment in a harmful form for a long time. Its stability makes it difficult to decompose in soil and water, but its toxicity is low and its influence on aquatic organisms, animals and plants is limited.
