Oolitic aragonite beads and methods therefor
Disclosed herein are personal care and/or cosmetic compositions, comprising a carrier and oolitic aragonite beads having an average diameter between 10 nm to 10 mm. Also disclosed herein are methods of reducing plastic contamination and/or pollution comprising making a cosmetic or personal care composition, wherein at least a portion to all (100%) of the plastic microbeads in the cosmetic or personal care composition are replaced with oolitic aragonite. Also disclosed herein are a milling system and milling methods for producing oolitic aragonite particles having a clean top size in which the particles are screened to remove any oversized particles. Additional uses include drug-loaded aragonite particles for therapeutic drug delivery and chromatography media.

2. The composition of claim 1 , wherein the oolitic aragonite particles have a D50 PSD of between 2.5 to 3.5 μm.
3. The composition of claim 1 , wherein the oolitic aragonite particles are loaded with a molecule.
4. The composition of claim 1 , wherein the oolitic aragonite particles are surface treated.
5. The composition of claim 3 , wherein the molecule is a chemotherapeutic.
6. The composition of claim 3 , wherein the molecule is a protein and the oolitic aragonite particles are functionalized to bind the protein.
