Is Tamanu Seed Oil sustainable?
This material is plant-derived, renewable, and readily biodegradable as a fixed oil. Sustainability depends mainly on it sourcing, regional traceability, and whether harvesting supports rather than pressures tropical coastal ecosystems.
Is Tamanu Seed Oil COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard, especially through mechanical pressing or approved extraction methods. It aligns well with Green Chemistry principles through renewable feedstock, biodegradability, and relatively low-processing production.
How does Tamanu Seed Oil work chemically?
Chemically, it is a triglyceride-rich fixed oil dominated by oleic and linoleic acid residues, with smaller saturated fatty acid fractions and minor resinous botanical constituents. It is commonly used around 1% to 10% in emulsions and higher in anhydrous blends, and its unsaturated profile benefits from antioxidants and protection from heat, air, and light.
