This toothbrush has got medium-soft bristles. It is BPA free, Fair traded and vegan.
The handles are biodegradable, environmentally sustainable, and do not pollute the environment. They are made of MOSO bamboo, which is heat-treated to prolong its life. Bamboo is a natural cellulose fibre, it is the fastest growing plant on earth, and incredibly abundant. This bamboo is cultivated for between three to five years, and then harvested. It re-generates itself naturally, with minimal rain and without the need for harmful pesticides. It is grown by many local farmers (NOT PLANTATION).
The bristles are made from a BPA FREE polymer resistant to microbial growth during normal use, to ensure safety and durability. The Environmental Toothbrush company tried to find a biodegradable bristle, but, as of this time, there is nothing available – apart from boars hair (don’t want to go there).
They are not Nylon 4 (as far as we know there are no bristles made from Nylon 4 on the market today). This company have tried to bring you a toothbrush that is better for the environment- over the years everyone had been misled by manufactures about bristles being made of Nylon 4 (this is not true). This toothbrush is a better alternative to a full Plastic toothbrush. Better to be 99% Bamboo than 100% PLASTIC.
Many companies claim that their bristles are made from castor beans. That is basically true, but there is a great deal of chemical processing involved. The bristles are made of Nylon-11 that in turn is made from 11-aminoundecanoic acid that in turn is made from castor oil by a complex process. First castor oil is converted to methyl ricinoleate by treatment with methanol, then is pyrolysed at high temperature to heptaldehyde and methyl undecylenate that is then hydrolysed to undecylenic acid. And then just three more reactions yield gamma-aminodecanoic acid that can be polymerized to Nylon-11.
HOW TO USE
Always rinse and dry your toothbrush after use to keep it clean. DO NOT chew on the toothbrushes or use excessive force in brushing as this may result in bristles being pulled out.
For best results, most dentist’s recommend you replace your toothbrush either monthly or at least every quarter.
HOW TO DISPOSE
The Environmental Toothbrush handle can be disposed of safely by returning it to earth in compost or landfill. The bamboo handle will biodegrade into the soil without pollution. Remove the bristles and place them into the bin.
