Ultramarine blue has a long history of use as a bluing agent in detergent and laundry products. The principle is simple: a small amount of blue pigment offsets the yellow tint that naturally accumulates in white fabrics, making them appear brighter and whiter to the human eye.
This optical whitening effect works because the human eye perceives a near-neutral color as white when it has a slight blue tint. Ultramarine blue shifts the color balance of yellowish fabric to a neutral or slightly blue tone that appears pristine white.
Detergent-grade ultramarine blue is formulated to be water-dispersible for easy incorporation into liquid and powder detergent formulations. It must be compatible with detergent surfactants, builders, and other ingredients without affecting cleaning performance.
Shree Krishna Ultramarine Pigments (P) Limited produces ultramarine blue grades suitable for detergent applications. Our detergent-grade pigment meets purity and safety standards required for consumer products and disperses easily in both liquid and powder formulations.
As consumers continue to demand effective, safe, and eco-friendly laundry products, ultramarine blue’s non-toxic, biodegradable-friendly profile makes it a preferred whitening agent compared to some synthetic optical brighteners.
