Lapachol ●
TL;DR. This ingredient is used mainly as a colorant or dye-type cosmetic material, especially in niche or experimental hair and skin-color applications. It is not a common moisturizer, emulsifier, preservative, or everyday skin-care active.
What does Lapachol do in a cosmetic formula?
This ingredient is used mainly as a colorant or dye-type cosmetic material, especially in niche or experimental hair and skin-color applications. It is not a common moisturizer, emulsifier, preservative, or everyday skin-care active.
Is Lapachol clean?
Clean-beauty programs tend to view this ingredient with friction because it is a reactive quinone-type molecule with irritation, sensitization, and broader safety questions in the literature. It is not a routine choice in clean-standard formulas.
Is Lapachol sustainable?
This material can be obtained from certain hardwoods or made synthetically, so sourcing depends heavily on supplier route. Wild or poorly documented botanical extraction raises traceability concerns, and the molecule is not a strong fit for simple, readily biodegradable ingredient profiles.
Is Lapachol COSMOS-approved?
This ingredient is not a clear fit for COSMOS-natural or COSMOS-organic use as an isolated dye-type molecule, and suppliers would need specific documentation for any compliant natural-source route. Its reactive quinone chemistry and uncertain biodegradation profile make it weakly aligned with Green Chemistry preferences.
How does Lapachol work chemically?
The molecule is a prenylated 1,4-naphthoquinone, combining an aromatic diketone system, a phenolic hydroxyl group, and a lipophilic isoprenyl side chain. It is poorly water-soluble, pH- and light-sensitive, and can participate in redox reactions, so formulation requires attention to solvent choice, color stability, oxygen exposure, and packaging.
