What is Natural Blue Indigo?
Indigo is an ancient dye derived from the leaves and stems of the Indigo tinctorial plant and its global use can be traced back for 1000s of years. Blue is one of nature’s rarest and prized colours. We supply cosmetic quality indigo in block or powdered form.
Uses of Indigo in Natural Cosmetics
For any cosmetic ‘leave-on’ applications, do a skin patch test first and use the milder ‘cosmetic indigo’
Use indigo block or powder in recipes for homemade eye shadow, eye liner, mascara etc.
Use indigo powder as an ingredient in natural sunscreens.
Skin Whitening / Lightening
Use powder in recipes to combat melasma, hyperpigmentation and dark spots.
Use indigo powder for recipes for dyeing blonde or white hair blue or for dyeing brown hair dark brown or black – Please note we sell less valuable ‘green’ Indian Indigo for use as hair dye too which works out much more economical for hair dyeing. Our Indian indigo is the dried leaf and unlike out blue indigo power, it has not been cured and fermented.
Use indigo powder to promotes hair growth and strength, helps to reduce hair loss and greying.
Blue Rinse for Hair
Use indigo powder to improve the appearance of grey hair – a blue rinse counters the yellow tones and makes the hair look blue-grey.
Use indigo cosmetic powder to create temporary tattoos and body art with blue indigo (we have pure henna too)
Whiten your whites with cosmetic indigo. Indigo is the original laundry bluing. Over time bleached white textile take on a yellow tinge, especially when washed with hard water. Use indigo as a natural optical enhancer to whiten whites. Bluing can be achieved with either cosmetic indigo powder or cosmetic indigo blocks.
For whitening in the washing machine
With powder – place 1/4 teaspoon of powder in a jar or water and shake or stir to mix. Add 1/5 to 1/4 of the blue mixture into the fabric conditioner compartment of your washing machine.
Next time you use the laundry blue you have made in a jar, shake it or stir it to disperse the indigo again in the bluing concentrate.
For whitening hand washed items
Or if washing by hand, add less of the blue mixture into the final rinse water (because the load size is smaller). Agitate the clothing well or soak for a few minutes.
You can also use an indigo block when hand washing – place the block in a cotton bag or old sock and dip in and out of the warm rinse water until the desired shade is reached. Then add the clothing to the rinse water as before. Keep agitating the clothes and draw them in and out of the blue rinse water until the optimal white hue is achieved. Wring the clothes out and dry them. Allow the indigo laundry blue block to dry and store carefully.

How Natural Spa Supplies Blue Indigo is Made
Indigo harvesting takes place through the summer from June until September as individual ripened leaves are collected. After harvesting, the plant is washed to remove soil, at this stage already, the purity of the indigo is notably increased. The leaves are crushed into a pulp with a stone mill, and the paste is then gradually dried in a barn until it is judged ready to roll by hand into fist sized balls, known as ‘cocagnes’. The cocagnes are placed on racks in the curing barn to cure again and to continue drying for between one and two months. At the end of this curing process, the cocagnes are known as ‘pastel de Cocagne’
Finally, to prepare the dye, the balls are crushed into a powder which is mixed with water and goat and camel urine for the main fermentation in which the purity of the dye will be enhanced further! The mixture is agitated to control the temperature and to bring about a permanent change. The pigmented sediment is allowed to form a sediment and dry again before being broken into blocks or cubes. By using these ‘slow’ and traditional methods, it means that no caustic chemicals are used in the production of our indigo and that it is safe for use on the skin and hair.
In many of the cosmetic applications, the indigo is used in its insoluble form such as when it is used as eye shadow, the pigment stays on the skin surface, in laundry bluing, particles of indigo are trapped in the fibres, likewise with a blue hair rinse. However when using indigo for dyeing textiles, as the indigotin is insolubale in water, an alkaline agent and a reducing agent is added to the dye vat containing the blue indigo powder to reduce the indigotin (removing 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.

Our indigo is made for Natural Spa Supplies in Morocco using time honoured methods. This is the genuine Indigo – which has been fermented in goat and camel urine! We have carried on this method not just to preserve human heritage but because in this way, we can obtain the purest indigo powder without the use of industrial chemicals.
While the production level is too small to gain organic status and the indigo plant does not need fertilizers or chemical treatments, in fact indigo plants are leguminous and use soil bacteria to fix nitrogen from the air. In that way indigo planting leaves the soil enriched with nutrients to help other crops to grow well. Indigo plants are used in interplanting and intercropping schemes as well as a cover crop to enrich the soil.
