The ingredients according to Procter & Gamble: bicomponent monofilament system, nylon, Peabax, microcrystalline wax, mineral oils, BHT, mint, saccharin.
BHT is considered carcinogenic substance, allergenic and potentially teratogenic. It may be critical in small quantities and will not be harmful to everyone, but when you consider how many products these and similar additives are included, then adds up the time.
I will not order this product, even though I am otherwise very happy with the band. It would be desirable if P & G would use alternative, non-critical additives that there certainly.
