Description

Kernechtrot-Aluminum Sulfate is a specialized aluminum lake pigment, also known as Carmine Aluminum Lake, primarily used as a vibrant colorant. This compound matters for its excellent stability and opacity, providing consistent, fade-resistant coloration in demanding applications. It is essential for manufacturers in the cosmetics, food, pharmaceutical, and industrial coatings sectors who require a high-quality, inorganic red pigment for their products.

Application

• Primary colorant in lipsticks, eye shadows, blushes, and other cosmetic powders.
• Pigment for pharmaceutical tablet coatings and gelatin capsules to provide color coding and branding.
• Food-grade color additive (where certified) for confectionery, dairy products, and beverages.
• Coloring agent in soaps, shampoos, and other personal care formulations.
• Industrial pigment for inks, plastics, and specialty coatings.
• Used in artist's paints and pigments due to its color fastness.

Quality Control

Our Kernechtrot-Aluminum Sulfate is produced under strict quality management systems. Each batch undergoes rigorous testing for color strength, purity, heavy metal content, and microbiological limits to ensure compliance with relevant standards such as FCC, USP/NF, EU, and JECFA for applicable grades. A Certificate of Analysis (COA) documenting all specifications is available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed after opening to prevent moisture absorption and color degradation.
