Optical Brighteners are a type of fluorescent dye, or a compound such as white dye. Optical Brighteners can excite incident light and produce fluorescence, and finally the object will be sparkling, and the whole object will look very white. Optical Brighteners can also be used in many places, such as textiles, plastics, paints and other industries. In daily life, it can also be used in products that need to be increased and brighter.
In life, we will also come into contact with Optical Brighteners, such as clothes, we will directly come into contact with Optical Brighteners, or we will indirectly come into contact with Optical Brighteners when washing clothes with laundry detergent.
In life, Optical Brighteners can be divided into portable Optical Brighteners and non-portable Optical Brighteners. Only portable Optical Brighteners will be transferred to the human body. Of course, using a large amount of Optical Brighteners will cause harm to the body.
Some people use fluorescent pens to test fluorescence. Is this method accurate? The answer is not necessarily accurate. First of all, some fruits or other things will also have weak fluorescence, because these widely existing substances in nature contain natural fluorescent substances, which are harmless to the human body. And only some optical brighteners are harmful, so using a fluorescent pen can only prove that the item contains optical brighteners, but it cannot distinguish whether it is natural fluorescence or chemical fluorescence, and it cannot detect which optical brighteners it is or whether it is a standard dosage.
