What Is The Main Difference Between Organic And Inorganic Pigments?

The main differences between organic pigments and inorganic pigments are as follows:

Ingredients and sources:
Organic pigments: mainly derived from plants or synthetic organic matter, made of carbon-containing organic matter as the main component.

Inorganic pigments: based on metal ions, oxides or other inorganic substances, most of them are made of inorganic compounds.

Color characteristics:
Organic pigments: bright, rich, bright colors, with a wide variety of colors and high tinting power.

Inorganic pigments: relatively dull colors, incomplete color spectrum, poor color brightness.

Stability:
Organic pigments: poor stability, easily affected by light and heat, causing color fading. Most organic pigments have a temperature resistance of no more than 300 degrees.
Inorganic pigments: good stability, good resistance to sunlight, heat, weathering, solvents, strong hiding power.
Mixability:
Organic pigments: Due to poor stability, they are easy to mix with other pigments to make more colors.
Inorganic pigments: good stability, difficult to mix with other pigments.
Uses:
Organic pigments: are more commonly used in plastics, rubber, inks, color pastes, paints, coatings and other related uses.
Inorganic pigments: are widely used in building materials, enamel, ceramics, glass, outdoor coatings, etc.
Price:
Organic pigments: relatively high prices.
Inorganic pigments: relatively cheap prices because they are made of minerals.
Toxicity:
Organic pigments: generally less toxic, but some synthetic organic pigments may contain compounds that are harmful to the human body.
Inorganic pigments: some metal salts and oxides are highly toxic, but with increasingly stringent environmental regulations, non-toxic, environmentally friendly inorganic pigments that can replace traditional lead and cadmium pigments are becoming popular.
Particle size:
Organic pigments: smaller particle size.
Inorganic pigments: relatively large particle size.

There are significant differences between organic pigments and inorganic pigments in terms of composition, color characteristics, stability, miscibility, use, price, toxicity and particle size. In practical applications, the choice of which pigment to use should be based on specific needs.
