Iron oxides, similar to ultramarines, are pigments that have been extracted and filtered of harmful impurities. This pigment can be used by itself in bodycare applications or to deepen the tone of other colours in various applications.

It can be used for tinting cosmetics such as foundations, blushes, eyeshadows, eye liners as well as to colour soaps. It has been proven to be stable in soaps and will not change shape or colour in cold process or melt and pour soaps. One of its drawbacks though is that it tends to clump and you will need to be especially careful to de-clump first before adding to your recipe. To de-clump beforehand, use a hand mixer to pre-mix your pigment in with a deodorised fixed oil, such as sweet almond oil or olive oil, before adding to your soap. This will help disperse and break up any clumps. The coloured oil can then be added to the soap batter at trace when making cold process soap.

For melt and pour soap, the pigment should first ideally be mixed thoroughly with glycerine to get rid of speckling and can then simply be added to the melt and pour soap.

The 15g option is packaged in a clear vial whilst larger options come packaged in resealable ziplock standup pouches.
