Today, optical brighteners are an indispensable part of all washing powders. They are dyes that are absorbed by textile fibers from the solution but are not removed during the washing process. Optical brightener CBS-X convert invisible ultraviolet light into visible light on the blue side of the spectrum, making the fiber reflect more visible light and making it appear brighter. In addition, since the tone of the extra reflected light is on the blue side of the spectrum, this blue-violet hue will complement any yellow on the fiber, making the fiber look whiter and brighter.

Pigment Violet 23 is a transparent purple pigment with high saturation and high tinting strength. C.I. Pigment Violet 23 has better tinting strength in soft PVC, but poor migration resistance. P.V.23 heat resistance above 230℃ in polyolefins. When used in transparent polystyrene, the temperature should be lower than 220°c, above which PV 23 should decompose. When processed in polyester, the temperature is 280℃, stable within 5 hours, and the concentration is above 0.05%. Pigment Violet 23 Purity 99%min with CAS No 6358-30-1

Ultramarine Blue is a saturated, semitransparent, dark, violet-leaning blue.Ultramarine is a complex sodium silicate containing sulfur and aluminum with the chemical formula Na7Al6Si6O24S3. The intense and distinctive blue color is caused by the unpaired electrons in the sulfur radical anion s3-. Ultramarine has heat and alkali resistant properties. It is chemically stable under normal conditions and resistant to high temperatures.The pigment is also resistant to alkaline solutions and can therefore be used in frescoes. It is usually be used as a colourant and optical brightener for plastics, rubber, inks, color painting, textiles, paper, cosmetics, detergents, cement and architecture.Ultramarine's unique property of flocculation—the tendency of its particles to clump up together—give it a lively granulating texture in washes.
