Zeaxanthin ●
TL;DR. This ingredient is used mainly as a colorant and antioxidant skin-conditioning additive, adding a yellow to orange tone while helping slow visible oxidation in oil phases. It is a minor active or pigment, not an emulsifier, surfactant, or preservative.
What does Zeaxanthin do in a cosmetic formula?
This ingredient is used mainly as a colorant and antioxidant skin-conditioning additive, adding a yellow to orange tone while helping slow visible oxidation in oil phases. It is a minor active or pigment, not an emulsifier, surfactant, or preservative.
Is Zeaxanthin clean?
Clean-beauty frameworks generally view it as low-concern when purity and residual solvent controls are documented. Sensitization reports are uncommon, but its strong color and oxidation sensitivity make dosage and packaging relevant.
Is Zeaxanthin sustainable?
This material can be obtained from plant, algal, or microbial sources, which can support renewable sourcing when documented. It is not associated with the persistence concerns linked to silicone or fluorinated materials, although extraction method and solvent choice matter.
Is Zeaxanthin COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic when derived from approved natural sources with compliant extraction and processing, while synthetic or non-compliant solvent-derived grades may not qualify. From a Green Chemistry view, renewable feedstocks, solvent choice, and protection from oxidation are the main alignment points.
How does Zeaxanthin work chemically?
The molecule is a polar C40 tetraterpenoid with an extended conjugated double-bond system and two hydroxyl groups, which explains its strong color, lipophilicity, and singlet-oxygen quenching behavior. It is oil-dispersible, sensitive to light, oxygen, and heat, and is commonly used at very low ppm to 0.1% levels with opaque or air-limited packaging and compatible oils.
