It is also a widespread myth that glowstick chemicals cause cancer. Also it is wise to avoid all contact with thin membranes such as the eye or nasal area. Despite reports to the contrary, it is not safe to smoke or ingest glowing phenol, and it will not produce any drug-like effects. The fluid contained in glowsticks can also dissolve some types of plastic. Newer glowsticks in production are non-toxic. Flush eyes immediately with cool water if liquid comes in contact with the eyes.
Some of the chemicals in glow sticks are flammable. The glowstick contains two chemicals and a suitable fluorescent dye sensitizer, or fluorophor. The chemicals in the plastic tube are a mixture of the dye and a derivate of phenyl oxalate ester also called Cyalume. The chemical inside the glass vial is hydrogen peroxide.
By mixing the peroxide with the phenyl oxalate ester, a chemical reaction takes place; the ester is oxidized, yielding two molecules of phenol and one molecule of peroxyacid ester. The peroxyacid decomposes spontaneously to carbon dioxide , releasing energy that excites the dye, which then deexcites by releasing a photon. The wavelength of the photon—the color of the emitted light—depends on the structure of the dye. The dyes used in glowsticks usually exhibit fluorescence when exposed to ultraviolet radiation.
Therefore even a spent glowstick will shine under a black light. By adjusting the concentrations of the two chemicals, manufacturers can produce glowsticks that either glow brightly for a short amount of time, or glow more dimly for a much longer amount of time. At maximum concentration typically only found in laboratory settings , mixing the chemicals results in a furious reaction, producing large amounts of light for only a few seconds. If you come into contact with the contents of a glowstick simply wash the affected area with clean water.
Please do bear in mind that with correct use and under normal circumstances you are very unlikely to come into contact with the contents of a glowstick.
OK so glowsticks are pretty simple products so are they all the same? The simple answer is no. The materials used to make the glowsticks can be made cheaply with a focus on minimal cost or they can be made with the intention of making a good product.
To activate your glowstick regardless of size, you simply need to apply gentle pressure to the centre of the glowstick in a similar motion as if you were to break a pencil in half. This will then break the vial and allow the chemicals to mix creating the glow. Simply give it a shake to complete and enjoy your glowstick for a minimum of 8 hours! However they are also useful to us with a wide range of uses such as fishing, caving, diving, camping, night golf, night sports, high visibility, table decorations, flower arranging and of course fundraising and parties.
Night sports are a relatively new phenomenon and are becoming increasingly popular with sports such as night golf and night football leading the way. Glowsticks are as crucial to these games as the ball itself as they allow players to be seen and highlight key areas such as golf fairways, holes to aim for and goal mouths. Glow necklaces and glow bracelets are used to identify players and distinguish between teams, whilst in the case of night golf; glowsticks are applied to golf buggies, flags and to mark out hazards.
Glowsticks are really a one use only product; however it is true that the effect can be stalled by placing the glowstick in the freezer. As the extreme cold will slow down the chemical reaction in a glowstick thus preserving the glow, the opposite effect occurs when you place a glowstick in warmer temperatures. Whilst doing this the glowstick will burn much brighter, but the life of the glowstick will be greatly diminished as the chemical reaction ends much quicker. A glow product cannot be reactivated or turned on or off, however the freezer trick will mean that you can prolong the life of your glow products if desired.
As well as the hydrogen peroxide contained within the glass cylinder inside the glow stick, the reaction of the diphenyl oxalate with the hydrogen peroxide can also produce small amounts of phenol as a byproduct. Skin contact with the solution contained within glow sticks can therefore cause some unwanted effects, including irritation and dermatitis.
On a final note, glow stick reactions, like many chemical processes, can be influenced by temperature. Warmer temperatures will accelerate the rate of reaction, whilst cooler temperatures will decrease it. Want to make your glow sticks last longer? Stick them in the freezer!

The substance inside these glowing items is usually dibutyl phthalate - a clear, oily, colorless liquid. It is low in toxicity but can cause irritation to any part of the body that it comes in contact with, including the eyes, skin and mouth.
