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.

    I have recently been trying the Argan Oil / Blue Indigo combination as a sunscreen. Usually I burn very easly – I have very fair skin – and I don’t usually tan unless much further south.
    I gave the sun a very good chance – sitting with face full on to the sun on a couple of the very hot and sunny days, inviting the sun to do its best – and no burn! Even a bit of a tan!
    A few days afterwards I was out in hot sun all day and had the oil on my face – just one application. Again my face didn’t burn but my exposed shoulders were red and sore. Next time I’ll remember to oil the shoulders too!
    I will definitely recommend this; it’s so good to find a sunscreen which is effective and doesn’t contain any dubious ingredients.

    This stuff is amazing!
    I used the argan oil and indigo combination for sun protection and found that it really does work. I am an organic market gardener, so I’m out in all weathers. I thought that I would try out this natural combination and it’s been great. I wasn’t sure if it was working or not (I have been out in strong sunshine, but maybe my skin is a bit used to the sun…) & then I realised that I had missed a bit, and that skin burnt. I can’t believe that something so simple is so effective. I am fair skinned and it feels great to find such an easy solution.

    Just wanted to let you know that your little bag of blue powder is magic! I hoped it would work but didn’t really have high hopes to be honest. I had some cotton bedding that had yellowed and it’s now back to a lovely blue white. Thank you so much.

    Super impressed with its whitening ability. My bedding and linen napkins looks so much brighter. Never be without it. Highly impressed!!

    Bought this to use with the soap nuts to brighten my white laundry items. Wow, it works! I have to say that after washing with soap nuts and using this as a brightener, my whites look better than they did when I used commercial washing liquid. Very impressed!
