Organic Pigments

Description

Organic pigments are colored, insoluble compounds made from carbon-based molecules that are used to impart color to a wide range of materials, including paints, inks, plastics, textiles, coatings, and cosmetics. Unlike dyes, organic pigments do not dissolve in their application medium but remain as finely dispersed particles.
They are called "organic" because their molecular structure is based on carbon, often derived from petrochemical or natural sources.

Key Characteristics

• Carbon-Based Structure: Comprised mainly of carbon atoms arranged in conjugated systems.
• Water Insolubility: Do not dissolve in water, which prevents bleeding and ensures color permanence.
• Low Toxicity: Generally safer and more environmentally friendly than many inorganic pigments.
• Chemical Stability: Resistant to acids and alkalis under typical conditions.
• Good Compatibility Suitable for use in paints, inks, plastics, textiles, and cosmetics.
• Moderate Thermal Stability:Can degrade at high temperatures.
• Strong Tinting PowerEffective in small quantities.
• Cost-EffectiveUsually less expensive than some inorganic pigments, though prices vary by type.
