1.Product Description
Phthalocyanine Blue 15:4 (P.B. 15:4) is an innovative high-performance water-soluble copper phthalocyanine organic pigment, redefining aqueous-based coloration with its unique tetrasulfonated molecular structure—setting it apart from non-soluble phthalocyanine blue variants (e.g., P.B. 15:1, 15:3). Unlike ordinary water-soluble blue pigments that suffer from poor color saturation, low dispersion, or rapid fading, our P.B. 15:4 features a proprietary sulfonation modification process, delivering three client-centric advantages: exceptional water solubility, vivid true blue hue with subtle green undertones, and seamless integration into all aqueous formulations—solving manufacturers’ pain points of uneven color, sedimentation, and limited application scope in water-based systems.
Crafted with advanced low-temperature sulfonation and purification technology, Phthalocyanine Blue 15:4 boasts a uniform fine particle size (0.10–0.16 μm) that ensures instant dispersion in water and aqueous formulations, eliminating clumping and production waste. Its 100% compliance with REACH, RoHS, and FDA standards (safe for cosmetics, food-contact paper, and children’s products) adds an extra layer of value, making it suitable for high-end and consumer-facing aqueous-based products. What truly differentiates it is its versatility in aqueous systems—performing flawlessly in water-based inks, coatings, and textiles, while maintaining compatibility with partial solvent-aqueous hybrids.
Engineered for long-term reliability, P.B. 15:4 boasts Grade 7–8 lightfastness (among the highest for water-soluble organic pigments) and thermal stability up to 200°C (short-term processing), retaining its vivid true blue hue even under UV exposure and high-temperature aqueous curing. Its excellent chemical resistance (resistant to weak acids, alkalis, and common organic solvents) prevents color bleeding and fading, ensuring consistent performance in diverse aqueous applications. It’s not just a water-soluble blue pigment—it’s a cost-effective, safety-compliant solution to elevate the aesthetics and performance of your aqueous-based products, standing out in a market saturated with ordinary blue pigments.

The vivid true blue hue with subtle green undertones delivers sharp, clear prints with excellent color clarity, making it ideal for luxury packaging, food labels, and promotional materials. Its Grade 7–8 lightfastness ensures prints retain their vibrancy for years, even under outdoor exposure or frequent handling.
3.2 Water-Based Coatings
Perfect for water-based architectural coatings, wood coatings, and industrial coatings, Phthalocyanine Blue 15:4 offers excellent compatibility with acrylic, latex, and water-based resin systems. Its uniform dispersion ensures even color distribution, creating a smooth, flawless finish without visible pigment particles. Its thermal stability up to 200°C ensures consistent color during coating curing, while its chemical resistance prevents fading or discoloration from weak acids, alkalis, and environmental pollutants. It is ideal for interior/exterior wall paints, furniture coatings, and metal protective coatings, delivering a premium blue finish that combines aesthetics and durability.
3.3 Textiles & Paper Coloring
Applicable to water-based textile dyes for cotton, polyester, and blended fabrics, Phthalocyanine Blue 15:4 delivers excellent color fastness (wash fastness up to Grade 5, rub fastness up to Grade 4–5), retaining its vivid hue even after repeated laundering and exposure to sunlight. It is also suitable for paper coloring, including high-end printing paper, packaging paper, and decorative paper, adding a bright, consistent blue tone that enhances paper aesthetics. Its non-toxic, FDA-compliant formulation makes it safe for food-contact paper and children’s textile products, expanding its application scope.
3.4 Cosmetics & Other Aqueous Applications
Phthalocyanine Blue 15:4 is EU-approved for cosmetic use, making it suitable for water-based cosmetics such as lotions, creams, and lipsticks. Its high water solubility ensures uniform color distribution, while its non-toxic, heavy metal-free formulation meets strict cosmetic safety standards. Additionally, it is used in water-based plastic formulations, aqueous adhesives, and water-based inks for toys, offering a safe, cost-effective solution for diverse aqueous-based products. Its versatility and performance make it a one-stop choice for all your water-soluble blue pigment needs.
