What is Natural Blue Indigo?
Indigo is an ancient dye derived from the leaves and stems of the Indigo Tinctoria plant and its global use can be traced back thousands of years. Blue is one of nature’s rarest and most prized colours and indigo is considered to be the ultimate in natural blue dyes.
How Natural Spa Supplies Blue Indigo is Made
Our indigo is made for Natural Spa Supplies in Morocco using an ancient process with a vital fermentation in goat and camel urine. This ancient method produces a very pure indigo with no aroma. Using these 'slow' and traditional methods, means that no caustic chemicals are used in the production of our indigo making it safe for prolonged skin contact through textiles or in rinse off products such as soap. Our cosmetic and laundry indigos, with a shorter fermentation time are milder and can be used in products which are left on the skin.
Indigo Chemistry
When using indigo for dyeing textiles, as the indigotin is insoluble in water, an alkaline agent and a reducing agent is added to the dye vat containing the blue indigo powder. These reduce the indigotin (remove one oxygen molecule). The fibres can absorb the indigo while it is in the reduced state and when the dyed fibre is exposed to the air, the indigo white oxidizes and turns blue and insoluble again. The textile is now blue.
Shelf Life of Natural Blue Indigo Powder
If stored under optimal conditions, dry and dark, the shelf life is 10 years.
