Ultramarines ●
TL;DR. This ingredient is an inorganic colorant used to give formulas blue, violet, pink, or green tones. It is common in makeup, soaps, bath products, and some personal care formulas where stable, non-bleeding color is needed.
What does Ultramarines do in a cosmetic formula?
This ingredient is an inorganic colorant used to give formulas blue, violet, pink, or green tones. It is common in makeup, soaps, bath products, and some personal care formulas where stable, non-bleeding color is needed.
Is Ultramarines clean?
Clean-beauty frameworks generally treat this ingredient as acceptable when cosmetic-grade purity specifications are met. The main watchpoints are trace-metal limits and dust control during manufacturing, rather than typical leave-on skin irritation.
Is Ultramarines sustainable?
This material is mineral-derived or synthetically made from inorganic feedstocks, so it is not renewable and does not biodegrade in the usual organic-material sense. It is insoluble, environmentally persistent as a mineral particle, and not expected to bioaccumulate, but production can involve high-temperature processing.
Is Ultramarines COSMOS-approved?
It is generally permitted as a mineral colorant under COSMOS natural and organic standards when purity and heavy-metal limits are met. Its Green Chemistry fit is mixed because it is inert and low in bioaccumulation concern, but it relies on mined inorganic inputs and energy-intensive processing rather than renewable feedstocks.
How does Ultramarines work chemically?
The molecule is an insoluble inorganic aluminosilicate lattice containing sodium and trapped sulfur species, which create the characteristic color by electronic charge-transfer effects. It is highly stable to light and heat, used at pigment-level additions depending on shade intensity, and can be sensitive to strong acids, which may dull or release the color center.
