One 25ml bottle of optical brightener. This is the "blue whitener" which enables fabrics to look whiter and also causes the well know blue fluorescent effect (where white clothing glows in disco lights). It absorbs ultraviolet light and re-emits it as an intense and stunning blue. Optical brightener is applied to textiles by soaking and it is suitable for use on cotton and synthetics.

Our optical brightener is a stilbene / triazine type brightening agent, CI name is FBA 28. Fluorescent brighteners of this type make excellent laser dyes and although our optical brightener is a commercial grade and not specifically offered for laser work, users have reported it to be an excellent laser medium. In the picture you can see the bottle in a dark room illuminated by a UV lamp. To give you an idea of the background light levels, the bottle cap is white in daylight.
