5. Manufacturing Process
Identifying and source natural ingredients rich in pigments
raw materials are cleaned, crushed, or ground to extract the pigments
The extracted pigments are filtered to remove impurities
The extracted pigments are concentrated to increase color intensity
Evaporation and drying methods may be used

6. Manufacturing Process
For Liquid Colors:
The concentrated pigments are mixed with water, glycerin, or other suitable
solvents and stabilizers to create a liquid solution
The formulation is carefully adjusted to achieve the desired color strength and
stability
The liquid color solution is sterilized to ensure safety and extend shelf life
It is then packaged in appropriate containers

7. Manufacturing Process
For Dry Colors:
concentrated pigments can be dried using methods like spray drying,
freeze drying, or vacuum drying
Blending And grinding
quality control measures are implemented to ensure color accuracy,
stability, and safety
The final dry color powder is packaged in airtight containers
