Abstract
The present invention relates, in general terms, to a face mask. The present invention also relates, in general terms, to composite material, iron-iron oxide compositions and their methods of fabrication thereof. In particular, the iron-iron oxide composition comprises a cashew testa extract and iron particles and/or oxide core-shell particles. The iron-iron oxide composition can be used as an anti-microbial composition.
Claims19
An iron-iron oxide composition, comprising:
- a) a cashew testa extract;
- and
- b) iron-iron oxide core-shell particles, the core is an elemental iron core or an iron alloy core, and the shell is an iron oxide shell;
- wherein the cashew testa extract comprises a component selected from protein, amino acid, sugar, phenolic compounds or a combination thereof, the phenolic compounds selected from tannins, catechin, epicatechin, epigallocatechin, p-coumaric, gallic acid, or a combination thereof;
- and
- wherein the iron-iron oxide particles are at least partially passivated by the protein, amino acid, sugar, phenolic compounds, or a combination there of,
- wherein the shell further comprises a component from cashew testa extract.
