The ultramarin name refers to the term "overseas". At the time, the blue ultramarin came from the Lapiz Lazuli stone (very expensive pigment). Today it is of synthetic origin, like all the ultramarines offered on this page (one of the rare exceptions in our shop). Synthetic ultramarine powders are identical to 100% natural powders. They have the advantage of costing much cheaper and not containing any heavy metals (unfortunately present in 100% natural ultramarine powders, absent from the market given their astronomical cost).
Origin : United States
Properties : Dye.
Use : This product can be added as such to makeup. To color the soaps, we first recommend that you dilute the ultramarines in a little oil or vegetable glycerin. Start with very small quantities, because the ultramarines color a lot and can color the water (which does not matter in itself, but can be surprising). We recommend wearing the mask and gloves for handling these powders. For external use only. Concentration: 0.1 to 20%.
* Note that the ultramarines are unstable in an acid environment. They can free up hydrogen sulfide, suffering, and give a very unpleasant odor to the product (rotten egg smell). This is why it is best to use them in pH 9 and more soaps and avoid them in bath bombs.
Applications: Makeup, soaps.
