Vitamin K2 ●
TL;DR. This ingredient is primarily used as a skin-conditioning active and antioxidant-support ingredient, most often in targeted face or eye products. It is included for tone, visible redness, and under-eye care claims rather than as a structural emulsifier or preservative.
What does Vitamin K2 do in a cosmetic formula?
This ingredient is primarily used as a skin-conditioning active and antioxidant-support ingredient, most often in targeted face or eye products. It is included for tone, visible redness, and under-eye care claims rather than as a structural emulsifier or preservative.
Is Vitamin K2 clean?
This ingredient is not a common allergen flag and is typically used at low levels, which keeps irritation concerns modest for most formulas. Clean-standard review usually centers on purity, solvent carriers, and whether the grade is fermentation-derived or synthetic.
Is Vitamin K2 sustainable?
This material may be produced by fermentation or chemical synthesis, so its sustainability profile depends heavily on the supplier route. It is used in very small amounts, but it is lipophilic and less straightforward from a biodegradability standpoint than simple plant oils or sugars.
Is Vitamin K2 COSMOS-approved?
This ingredient has partial COSMOS alignment, with acceptance depending on origin, manufacturing route, and documentation for the specific grade. Fermentation-derived material fits Green Chemistry principles better than fully synthetic material, especially when renewable inputs and responsible solvents are used.
How does Vitamin K2 work chemically?
The molecule is a fat-soluble quinone with an isoprenoid side chain, which makes it oil-compatible and poorly suited to water-only systems without solubilization. It is light-sensitive and oxidation-sensitive, so formulators usually pair it with antioxidants, opaque packaging, and oil-phase or encapsulated delivery systems.
