Lakes

Lakes

Alimentary lakes offer an alternative to water soluble colours. Lakes are used when the product to be treated is a powder, or is made up of an fat matrix or has a heteregenous form. The colour does not become soluble, but "disperses" within the medium.

A lake is a pigment which is prepared from a primary water soluble colorant.
Aluminium pigments are prepared creating a reaction between coloring materials and aluminium in an aqueous environment; these colouring materials meet purity requirements defined in the relevant specifications.
After the formation of the pigment, the product is filtered, washed with water, dried and milled. For the related colours specific purity criteria apply(95/45/EC).

Concentration:

Lakes are available in different colour concentrations which affect the shades.
Colour intensity is not directly proportional to the concentration of pure colour.
There are no legal provisions defining minimum concentrations; usually pure colour content is not greater than 40%.
As the concentration increases, colour intensity increases, and powder colour matches the shade of the dispersed product.

Quality

Lake quality is closely related to:
1) Particle size: the finer the particles the greater the staining strength.
2) Bleeding: the percentage of non "pigmented" colour, which remains water soluble. This percentage must be low.

Lakes maintain specific characteristics at a ph level which is between 3.5 and 7.0. outside this range bleeding becomes significant.

How they are used

We recommend dispersing the lake in the matrix to be treated beforehand. This causes the colour to be distributed evenly in the product and shortens the subsequent mixing and conging phase.
