OzokeriteBarrier
A natural mineral wax that hardens balms and sticks — keeps oils from separating and raises the melting point.
What it does
A natural mineral wax. It also leaves a smooth film that seals moisture in.
The EU’s ingredient database lists it as a thickener (controls how thick the product is), an opacifier (makes the product less see-through) and a stabilizer (helps oil and water stay mixed).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
