what substance is in glow sticks
Then thereâs the two chemicals that react to give the dye its light. A common combination of chemicals is hydrogen peroxide and phenyl oxalate ester, plus the fluorescent dye. The chemicals in glow sticks can be combined in certain ways to have a brighter glow for a short period of time or a dim glow for a longer time.
Other glow products contain a small glass vial inside the plastic tube that contains a mixture of hydrogen peroxide in phthalic ester (a substance that is added to plastics to increase flexibility, durability and transparency). Outside of the glass vial is another chemical called phenyl oxalate ester.
