What is the difference between pigments and colorants?
Colorants are either dyes or pigments. Technically speaking, the difference is that dyes are soluble in the host material—typically water—while pigments are not. With a suitable chemical treatment, a soluble dye can be converted into an insoluble pigment.
Are pigments colorants?
These terms are often used interchangeably, but they have different meanings. Colorants are compounds that impart color to a substance. A colorant may be a pigment, a dye, or an ionized solution. Only insoluble materials such as minerals are pigments.
What are the types of colorants?
The five colorant categories include dry color, liquid color, paste dispersion, masterbatch, and compounded color. These colorants almost always contain dispersants and other additives. Masterbatches also contain resins or polymers.
What are colorants made of?
Plastic colorants are chemical compounds used to color plastic. Those compounds come in a form of dyes and pigments. The type of a colorant is chosen based on the type of a polymeric resin, that needs to be colored. Dyes are usually used with polycarbonates, polystyrene and acrylic polymers.
What is example of pigment?
A substance, such as chlorophyll or melanin, that produces a characteristic color in plant or animal tissue. Chlorophyll, which gives a green color to plants, and hemoglobin, which gives blood its red color, are examples of pigments.

What are plastic pigments?
Pigments are insoluble organic or inorganic particles added to the polymer base to give a specific color to the plastic. Pigments that are organic in nature are hard to disperse and tend to form agglomerates (clumps of pigment particles). These agglomerates can cause spots and specks in the final product.
