What is Sodium Polyacrylate?
Sodium Polyacrylate is a synthetic polymer made from acrylic acid. It is a white, odorless powder known for its high absorbency, capable of soaking up many times its weight in liquid.

You’ll find it in items like diapers and wipes to keep them dry, as well as in skincare products for its water-retaining properties. Health studies are generally focused on skin exposure, with mixed evidence on irritation risks.
While Sodium Polyacrylate is widely used, it is not without controversy. Some discussions center around its potential environmental impact upon disposal, given its synthetic nature.
