Bulking agents are generally harmless to humans within normal use, but can be harmful if poor quality bulking agents are used or if they are used in excess. Expanding agents are generally used in modern agriculture, food industry production, often used in the cultivation of fruits and vegetables. Generally speaking, if the bulking agents produced by regular manufacturers are used in accordance with the prescribed dosage, they will not cause harm to the human body.
