Aluminium Lake

Aluminum lakes are pigments created by combining water-soluble dyes with aluminum salts, which makes them insoluble in water but dispersible in oil-based formulations. This unique property makes aluminum lakes ideal for coloring products where water exposure would affect stability, such as in tablets, capsules, and certain cosmetic products. Their vibrant, stable colors hold up well under light, heat, and acidic conditions, making them a popular choice for long-lasting color in pharmaceuticals.

Fun Fact:
Aluminum lakes can be custom-formulated to achieve a wide range of colors, but they’re particularly valued for shades that are hard to achieve with water-soluble dyes, like certain reds and blues!
