In ancient costume dramas, hairpins were used to test and hide poison. How come modern hairpins are really poisonous? !

It is said on the Internet that the hairpin-making liquid is acetone, which is poisonous. Therefore, many netizens believe that hairpins are poison and wearing and making hairpins will cause harm to health. In fact, this statement is too exaggerated.

First of all, acetone is indeed a toxic liquid. It is highly volatile and smells like mint at room temperature. Long-term inhalation may cause headaches and bronchitis symptoms, and large amounts of inhalation in a short period of time may cause coma. However, acetone is not highly toxic and is a low-toxic substance. Acetone is not the main ingredient in the crystal flower liquid, and acetone evaporates quickly and evaporates completely after use. Therefore, the rumor that talks about the toxicity of acetone without considering the dosage is misleading.

If the dosage is appropriate, it is even listed as one of the "extraction solvents allowed for natural flavorings used in food" in the Food Additives Use Standard (GB2760-2014), so there is no need to be afraid of acetone.

Of course, when using crystal flower liquid, it is recommended to operate in a ventilated environment. When drying crystal flowers, it is also best to place the flowers in a ventilated place.
