Rumors circulated in cyberspace that there were toothbrush products that used pig bristles. It is mentioned that Muslim consumers should be careful of brushes with the words 'bristle' written on the packaging because it means sea urchin. Is this news true? The Institute for the Study of Food, Drugs and Cosmetics, the Indonesian Ulema Council (LPPOM MUI) on its official website, tries to explain that bristle does not always mean sea urchin. The meaning of the word bristle in general can mean all hair or stiff fibers. "Hair, stiff beards, can be categorized as bristle. Another example is fibers or stiff pine leaves that can be called bristle," wrote LPPOM MUI quoted on Tuesday (1/11/2016). "One of the information that can be seen as a sign that a brush or brush comes from sea urchins is that it is written as a product name, for example 'Boar Bristle Brush'. Boar is an English term for wild boar or wild boar. This means that the product is a brush that uses wild boar bristles ," continued LPPOM MUI. drg Eva Fauziah from the Indonesian Pediatric Dentist Association (IDGAI) commented that the toothbrush in the market generally uses nylon bristles. Nylon as it is known is a synthetic fiber made from plastic. "Toothbrush bristles are usually made of nylon," said drg Eva when detikHealth met. If someone is suspicious of a toothbrush product, there are ways that can be done to determine whether the brush is made of animal hair or other materials. Simply burn the tip of the brush and smell if it smells like burning hair or horns. "If it smells like burning hair or horns, it's better to leave it alone. Materials from plastic or coconut fiber don't give off a distinctive smell like that when burned," closed LPPOM MUI. In the broadcast circulating through WhatsApp groups and social media, a picture of the back of the toothbrush product packaging is included. However, it seems that the product is not marketed for the Indonesian market. The broadcaster circled the word bristles in the toothbrush packaging while explaining its meaning.
