Description

Calcium Aluminium Lacquer With Carminic Acid CAS NO 93062-68-1 is a specialized pigment preparation, also known as a lake, where the natural colorant carminic acid is precipitated onto an inorganic substrate of calcium and aluminium. This product is engineered to provide superior color stability and opacity compared to the dye alone, making it a critical component for achieving vibrant, light-fast hues. It is primarily required by manufacturers in the food, cosmetic, and pharmaceutical industries seeking natural, compliant colorants for coatings, tablets, and decorative applications.

Application

• Coloring agent for pharmaceutical tablet coatings and sugar-shelled confectionery.
• Pigment for cosmetic products including lipsticks, blushes, and eye shadows.
• Natural colorant in food-grade decorative inks and edible printing.
• Ingredient in artists' paints and specialty industrial coatings requiring organic pigments.
• Color additive for plastic masterbatch formulations for food packaging.
• Used in the coloration of soaps and personal care bar products.
