In 2016, the US Food and Drug Administration limited the use of triclosan in some products as it was not proven to be safe for long-term use.
"We have detected that the highest levels of triclosan within the urine were related to a lower bone mineral density in the femur and the lumbar spine", lead researcher Yingjun Li from Hangzhou Medical College and School of Public health.
The research indicated that triclosan - used in a variety of consumer products - could have a negative impact on bone health as it interferes with the function of the thyroid.
The study, "Association Between Urinary Triclosan with Bone Mass Density and Osteoporosis in the US Adult Women, 2005-2010", will be published online, ahead of print.
Those with higher levels of triclosan in their urine were more likely to have bone issues, it was discovered.
The evaluation of over 1,800 adult U.S. women, published Tuesday in The Journal of Clinical Endocrinology & Metabolism, additionally unsurprisingly recommended older ladies with higher ranges of triclosan in their urine were more vulnerable to having weaker bones.
Triclosan is added to some antibacterial soaps and body washes, toothpastes, and some cosmetics.
The FDA declared antibacterial soaps containing triclosan are no more effective than hot water and regular cleansers at killing bugs. That's according to a study in Tuesday's Journal of Clinical Endocrinology & Metabolism. Consumer demand is slowly forcing certain manufacturers to phase out triclosan from their products.
Trace elements of it will also be present in clothes, kitchenware, cosmetics and toys with the intention of preventing germs.
When people use a product containing triclosan, they can absorb a small amount through their skin or mouth.
The study wasn't a controlled experiment created to prove whether or how triclosan might directly cause osteoporosis. Researchers have now linked the chemical to an increased risk of osteoporosis.
It is seen as a silent epidemic as many do not realise they have the disease until they break a bone.
The most common injuries in people with osteoporosis are wrist, hip and spinal bone fractures. The loss of bone occurs silently and progressively.
