With the continuous improvement of environmental awareness, the environmental risks of D4 have received increasing attention. Studies have shown that D4 is persistent, bioaccumulative and toxic, and can easily cause adverse effects on aquatic organisms. These cyclosilicone oil components will enter environmental water bodies with domestic wastewater and continue to accumulate in the environment. In addition, D4 is also reproductively toxic. In experiments with mice, it interferes with estrogen receptors and reduces the number of ovulations and the probability of pregnancy in female organisms. Therefore, restricting the use of D4 has become an important part of global environmental protection actions.
