A chain message about vigilance against toothbrushes made from pig bristles is spreading in the community. because there is the word bristle on the packaging of a global toothbrush brand. The message is not really new. The message was spread a year ago, but now it's crowded again. Let's check the toothbrush, if it says Bristle on the packaging, it means that the toothbrush contains pig hair. Bristle means pig hair. As soon as the sound of the message fragments spread again through the chat application. Not only on toothbrushes, the message maker also suggested that people check the bread brushes. He said that the brush usually says Bristle, Pure Bristle, 100% China Bristle. As with other hoax messages, the appeal was accompanied by a request to share the message with family and friends in the group so that more people would be spared from non-halal products. It turned out that the informant had misunderstood. Maybe, when he wrote the message, he had not had coffee. This is because the term bristle is not only used for sea urchins. According to the official website of the Indonesian Ulema Council (MUI), the term bristle is lexically a short, stiff hair, and fiber. Thus, all stiff hair fibers can be called bristle. In the industrial world, bristle is indeed used for making brushes or brushes (including toothbrushes). However, not all of them come from sea urchins. Bristle for brushes and brushes can be sourced from animal hair. Both pigs, goats, horses, and camels. Apart from animal hair, for industrial purposes, bristle can also be made from synthetic materials, either nylon or silicone. Plant fiber has also been used as a brush or brush material. The fiber is commonly known as palm fiber. The MUI has firmly stated that if a brush or brush uses pork bristles, it is illegal. However, producers usually write down in detail the raw material used for fur. Usually, for brushes or brushes with boar bristle material, it is written boar bristle brush. Boar itself is an English term that refers to a wild boar. Recognizing the raw material for a brush or toothbrush is not easy. However, you can determine whether the fur comes from animal hair or synthetic material by slightly burning it. If you smell hair, you can be sure that the fur comes from an animal. If it is made of synthetic material or coconut coir, the smell will be different. Referring to a number of sources, the use of bristles on toothbrushes was first carried out by the Chinese in the 15th century. At that time, the feathers on the pig's neck were used. The brush was later brought to the European market. However, Europeans prefer horsehair because it is softer. The first modern toothbrush was introduced by William Addis in England around 1780. The handle was carved from cow bone. And, the fur is still made of sea urchin, only one big row. Furthermore, in 1844, a toothbrush with three rows of bristles was designed. Modern technology has finally found nylon can be used as bristles on brushes. The technology was introduced in 1938. Since 1950, the toothbrush industry has mostly used nylon bristles.
