Optical brightener - Wikipedia

Properties. The most common classes of compounds with this property are the stilbenes, e.g., 4,4′-diamino-2,2′-stilbenedisulfonic acid.Older, non-commercial fluorescent compounds include umbelliferone, which absorbs in the UV portion of the spectrum and re-emit it in the blue portion of the visible spectrum. A white surface treated with an optical brightener can emit more visible light ...

Why Brightening Chemicals Aren't in Green Detergents

Optical brighteners are synthetic chemicals added to liquid and powder laundry detergents to make clothing appear whiter and brighter, and thus cleaner. They are the modern-day replacement for the decades-old practice of bluing—adding small amounts of blue dye to fabric to make it appear whiter.

Daz washing powder; Schweppes tonic water; Brown egg shells. Procedure. If this demonstration is to be successful, you will need to have a word with your technical staff to see whether they can make an ultraviolet light source. Our box is made from mdf and a uv strip light borrowed from the physics department. Prepare the following solutions:

What is fluorescent lighting?

Every fluorescent tube is coated with phosphor powder. If you stuck your finger in the tube and rubbed the inside, it would look like you just enjoyed a powdered doughnut. This phosphor coating glows when it is excited by the invisible UV light, and that is what we see with our eyes – glowing phosphor powder which creates a “white light.”

Colours that glow under black light

Jul 14, 2020·White paper, paint and fabrics are treated with fluorescent additives to make them brighter. These compounds react to the ultraviolet of the black light, casting them back quickly which emits that glow. Washing powder whiteners make clothing a bit fluorescent. White toothpaste with tooth brighteners glows incredibly strong.
