Water Soluble Synthetic colours are permitted for the food, pharmaceutical and personal care applications, colours are suplied in powder form delivering exceptionally high purity levels allowing for a infinite spectrum of powder shades, EDCOL's synthetic colours impart vibrant, stable colours to a product in a cost effective manner across the spectrum of the colours required by the food industry.
Over time EDCOL has developed a substantial range of blended colours which can be matched accrording to your spesifications using our colour mathching laboratory.
All EDCOL's colours comply with the FD&C Act 54 of 1972 - EDCOL takes colour blending very seriously, always taking the time to assure the highest quality in all our products with quality control and testing across our entire process, providing a great product and of course very importantly, a consistent product.
Lake Pigments are used where dyes are unsuitable due to their solubility in water. Some of the most common applications of Lake Pigments are coating application, icing application where the colour must not bleed, baked treats where colour migration is an issue and so on.
In general lakes are more stable than the corresponding water-soluble Colours, producing brighter more vivid colours and are most suitable for products containing oils and fats, or products lacking sufficient moisture to dissolve Colours.
Advantages & Limitations: (lakes v/s Colours)
- Stability to light - It is better than water soluble Colours.
- Stability to Acids and Alkalies - Satisfactory between pH 6-8.
- Solubility - Virtually insoluble in solvents and should have "minimum bleed" in water.
- Provided bright and vivid colours.
- Lakes are suitable for products containing oils and fats as well as those lacking sufficient moisture to dissolve Colours.
- Lack of interchangeability between colour suppliers, as minor batch to batch variation is common in pigments.
Beware that pure dye in Lakes in no way co-relates to the color value or colouring property/ability of the Lake. Since Lakes are pigments, their colouring is achieved through dispersion of tiny colour particles. The more finely ground the colour particles; the more effective a colour will be.
