Blue Lake Environmental Protection Blue Powder - Eco-Friendly Pigment for Coatings
Product Overview
Blue Lake Environmental Protection Blue Powder is an eco-engineered pigment derived from natural indigo derivatives and mineral complexes, designed to deliver intense blue coloration while adhering to stringent environmental standards. As a heavy metal-free, non-toxic alternative to conventional phthalocyanine blues, this pigment achieves CIE Lab* coordinates of L=40–45, a=–15 to –20, b=–45 to –50, producing deep oceanic tones ideal for architectural paints, toy coatings, and biodegradable packaging inks. Certified USDA BioPreferred (75% bio-based content) and compliant with EU Ecolabel, it combines exceptional lightfastness (ISO Grade 7–8) with full aquatic toxicity compliance (OECD 201/202/203).
Molecular Architecture & Synthesis
1. Chemical Composition
- Core structure: Indigotin-mineral complex (calcium phosphate/alumina matrix).
- Functional modifiers:
- Carboxylate ligands (-COO⁻): Enhance dispersion stability in waterborne systems.
- Plant-derived surfactants (saponin glycosides): Improve wettability in low-VOC formulations.
2. Manufacturing Process
- Fermentation Extraction:
- Hydrolysis of indigo plant (Indigofera tinctoria) leaves via enzymatic fermentation.
- Mineral Co-Precipitation:
- React with calcium phosphate at pH 8.5–9.0 to form lake complexes.
- Surface Optimization:
- 10–15% starch-based encapsulation for humidity resistance.
