Beauty is in the eye of the beholder

The bright effect of cleaners is usually claimed by the surfactants.

Completely unfair!

A stunning bright white result is initially obtained with the correct photo-chemistry, which is sheer magic.

Even the best quality detergents leave behind a grey haze on the clean surface. In addition, yellowing appears after repeated washing cycles. Too much grey and yellow is showing, too little blue wavelength is reflecting. Chemical producers such as Ciba, Eastman and others came to the idea years ago, to use photo chemicals to mask the yellow and grey. Photo chemicals are complex molecules which can be "activated" by radiation of certain wavelengths, as a result of which they will emit other wavelengths. This effect is known as fluorescence. Photochemical brighteners absorb UV and radiation in the yellow/grey part of the visible light spectre. They thus upgrade to an activated state and subsequently emit radiation in the blue part of the spectre. White light is a combination of red, yellow and blue. Abundances of grey and yellow can be compensated by extra blue. We experience the combination of colours as a whiter appearance.

Does this make the surface cleaner? No, it doesn't. But it looks brighter compared to "just clean"!

In addition: an optical brightener creates a higher light reflection anyway; the whiter mix of colours also becomes brighter.

The most logical application of optical brighteners is in washing powders. But there is more. There are special optical brighteners for synthetic fibres and plastics (which often yellow), paper and coatings. The paper on which you fax us your orders is really not that white by nature.

Only a little whitener is needed for an optically clean effect. The usual concentrations lie between 0,015 and 0,5% per weight of cleaner, plastic, paper and coating.

The inventors of this photochemistry for a long time marketed optical brighteners as high priced specialties. For the same long period the price has been an obstacle for other applications than the above mentioned. But as it goes with specialties: patents expire, copies appear and prices decrease. We would not present this information to you if we were not certain that we could offer optical brighteners competitively in price and quality. We have audited several Asian producers of optical brighteners.

Our Britemax® CBS-X now has the highest quality against a competitive price. The product is spray dried and has a monodisperse spherical particle size which results in easy dosing.

We keep stocks of Britemax® CBS-X, which can be ordered even per 20 kg or up to full containers.
