Our products are non-toxic. The outer layer, as well as the lining (in contact with the skin) of our panties are OEKO-TEX certified. This ecological certification, recognized internationally, aims to guarantee that textiles have been manufactured without substances harmful to human health or the environment. The other layers of materials we use are made without silver nanoparticles, without BPA and without PFOS/PFOA. Our supplier also holds CPSIA certification, which ensures that materials do not contain hazardous substances such as lead, cadmium, mercury, bisphenol A and phthalates.
