Shandong Raytop Chemical is a professional soap and detergent optical brightener manufacturer from the year 2006.
Although the action of optical brighteners resembles old-style laundry blueing in some ways, the two methods must not be confused. In the old method, a blue dye or pigment is adsorbed onto the fibre; this blue tends to absorb yellow light falling on it, reflecting light richer in blue. With blueing, however, the fabric absorbs some of the light falling on it and hence reflects less light than it receives. Thus, the fabric looks whiter, not brighter.
We Raytop Chemical would like to introduce our soap and detergent optical brightener CBS-X 351,CXT 71,DMS 71,and also can design new products as per customers’ request.
