Chemistry Class: Pigments, Mica and Colours for Soap and Cosmetic Making


Hi All,
today ill be talking about the colours that we carry in Soap Lab.
Many have enquired about colours and don't really know how to differentiate them and how to use it therefore I've decided to write the information here for future reference.



What type of Colour do Soap Lab Malaysia carry?
In Soap Lab we have Pigments, Micas, Oxides, and Rainbow by Soap Lab (an in house production colour).

Does Soap Lab carry natural colours?
Pigments and oxides are considered as natural identical colour where it has the exact same composition as the ones found in the earth. However they are created in lab to ensure high purity and less chemically destructible. These colours are usually labelled as natural in the cosmetic industry as they look and have the same chemical structure as the ones found in the earth. The reason why they are manufactured in lab is because there are lead and arsenic found in earth which can be harmful if used in makeup therefore these pigments and oxides are lab produced to ensure those items are not in these colours. These colours also don't contain synthetic dyes like other colorant does. Oxides and pigments are mostly used in mineral make up as they have gorgeous array of colours as compared to micas.

Mica on the other hand can be natural and can also be not natural. The ones we have in Soap Lab Malaysia are all natural source. We do not carry any colorant that contains carmine. Carmine although natural, is derived from crushed cells of beetle and since Soap Lab is a vegan store, we do not have any product with carmine red in store.

What is the INCI for each colour in Soaplab?
INCI stands for International Nomenclature of Cosmetic Ingredients, usually needed for labelling. Attached is the INCI for each colorant in Soap Lab:
Can i use Vegetable Natural Colourant in my Soap?
If you want a 100% natural colorant and don't want to use any of these additives, you can always get it from your natural vege colourant at home. For red: Beetroot Powder, Yellow: turmeric, Purple: Purple cabbage (powdered). Although it is doable, i suggest you do not use these natural vege colorant if you want to sell your soaps as they fade easily and are not pH stable so you might get spots where the colour would fade making it aesthetically horrible looking:(

Rainbow by Soap Lab? What is that and why is it different from the powder colorant.?
The colours from Rainbow are actually also pigments and oxides that are diluted for you. therefore its ready made liquid pigment and you do not need to dilute it when you get them.

  4. Hi Jue. for lips kindly get the set for lips mica.
    as for eyes you can use any but its advisable to get a coffee grinder and grind the mica and sieve it after that to make it into finer particles so it doesn't irritate the eyes. the current mica pigments we have now is slightly larger particles.

  7. Dear Nisha,

    1. Should I use the POWDER or LIQUID colorant if I'm making body scrub?

    2. Can I use LIQUID pigment (the Rainbow range) if my body scrub is gonna contain shea / mango butter?

    3. While I understand that the colors from Rainbow are actually diluted pigments and oxides, does this mean I can still label my body scrub as NATURAL & VEGAN? Since you said Soaplab carries natural & vegan colorants be it pigments/ oxide/ mica?

    Looking forward to your reply.

    Much love,
    Sarah
