Before 1940, white-pigmented paints typically used lead-based white pigments, such as lead carbonate (white lead), which provided excellent coverage and durability but posed significant health risks. After 1940, the use of lead was largely phased out due to safety concerns, leading to the adoption of safer alternatives like titanium dioxide, which offered similar opacity and brightness without the toxicity. This shift not only improved public health but also influenced paint formulations to be more environmentally friendly. The change marked a significant evolution in paint technology and safety standards.
