In fact. titanium is a natural element found in the earth's crust. However. it usually undergoes a significant manufacturing process to extract it from the ore and make it usable.

Titanium dioxide. a frequently used additive for whitening and UV protection. is found in various products including food and cosmetics. While there is no significant evidence suggesting that consumption or application of titanium dioxide leads to cancer in humans. the International Agency for Research on Cancer IARC considers it a potential carcinogen when inhaled excessively in occupational environments. More thorough research is required to fully comprehend the impact of regular exposure. As a precaution. individuals should carefully and responsibly use products containing titanium dioxide to minimize potential risks.

Polypropylene (PP) is a type of plastic widely used in various applications due to its resilience and low cost. Being a hydrocarbon polymer, polypropylene can indeed burn. When exposed to flame, it typically melts at around 160°C (320°F) and then ignites, burning with a bright, clean flame, producing water and carbon dioxide as combustion products, along with potentially toxic gases if combustion is incomplete. To mitigate fire hazards, polypropylene can be mixed with flame retardants that increase its resistance to ignition. However, it's essential to implement fire safety practices when handling or storing polypropylene products, especially in environments where open flames or high temperatures are present.
