The Muslim community was shocked by the news about toothbrushes made from pig bristles. One of the markers is the content of the toothbrush, bristle, which is listed on the packaging. The word bristle is then interpreted as a sea urchin. As a result, many Muslims are worried about using a toothbrush on the market. Quoted from the halalmui.org page, LPPOM MUI explains the term bristle means stiff hair or fiber. This definition refers to the Websters Dictionary, so all stiff hair, including stiff beards, palm fibers, pine leaves fall into the bristle category. In the industrial world, bristle is often used as a material for making brushes and brushes, including toothbrushes. Bristle materials can come from animals such as pigs, horses, goats, or synthetic fibers such as nylon and silicone. To emphasize what bristles are used on a toothbrush, usually the term bristle will be written in the product name. For example, Boar Bristle Brush which means Pig Bristle Brush. Boar means wild boar or wild boar. If you find a toothbrush with the above sentence on the packaging, then the toothbrush is declared forbidden to use. This means that the product is a brush that uses wild boar bristles. Toothbrushes can also use boar bristles, wrote LPPOM MUI, quoted from halalmui.org, Wednesday, November 2, 2016. However, not all toothbrushes that contain the term bristle in their packaging must be made from pig bristles. There are already many manufacturers that use horse, goat, camel hair, as well as nylon and silicone fibers in their toothbrush products. When there is no information on the source of the material, at least a simple method can be used. To determine whether it is made from animal hair or not, the method in question is to burn the material. If it smells like burning hair or horns, better leave it alone. Materials from plastic or coconut fiber do not emit such a distinctive odor when burned. wrote LPPOM MUI.
