Diatomaceous Earth

Diatomaceous Earth (DE) is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It is primarily composed of the fossilized remains of tiny, aquatic organisms called diatoms.

Clinical Applications

Enhanced Permeation and Stability

A study titled Diatomaceous Earth-Enabled Resveratrol Microemulsion for Enhanced Permeation and Stability developed a microemulsion system using DE for the topical delivery of resveratrol. The findings indicated that DE significantly enhanced the permeation and stability of resveratrol, making it a promising candidate for topical drug delivery applications.

Passive Cooling in Construction

Another research titled Elephant-Skin-Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling explored the use of DE in cement composites for passive cooling. The study demonstrated that DE's micro/nanoporosity allows for efficient water management, reducing energy demand for cooling in buildings.

Mechanical Properties in Composites

The article Effect of Fabrication Route on the Mechanical Properties of Polylactic Acid (PLA) Composites with Diatom Earth (DE) examined the mechanical properties of PLA composites reinforced with DE. The results showed that increasing DE content improved stiffness while affecting tensile strength, indicating its potential in eco-friendly material applications.
