The study looked at data from 1,848 women between 2005 and 2010 and found that women had higher levels of triclosan in the Urine was more likely to develop osteoporosis later in life. Osteoporosis is a metabolic bone disease in which a person loses bone mineral density. When the bones are weakened, there is an increased risk of fractures, back pain and loss of height.
This is the first study to uncover this relationship, researchers said.
Researchers believe that there is a negative association between bone health and triclosan, in part because of its Impaired thyroid function. Previous studies have shown that imbalance of the thyroid gland can lead to bone loss and an increased risk of fractures.
Triclosan is an ingredient that has been used in some hand sanitizers, toothpastes and cosmetics as well as in kitchenware, toys, furniture and medicines clothing. Products have been added to prevent bacterial contamination.
In 2016, the FDA began restricting the use of triclosan and other chemicals in some consumer products, as it turned out they are not safe and effective for long-term daily use. In April, the FDA issued a final ruling banning its use in over-the-counter hand sanitizers in the US. However, it is still included in some products.
Some previous studies on toothpaste use seemed to indicate that it was safe, but said further investigation was needed.
Some studies on animals showed that long-term exposure to the chemical increased the risk of the animal for skin cancer. Another study suggested that exposure to triclosan may interfere with some infant reproductive and developmental processes. Another study suggested a link with the spread of antibiotic resistance.
