Extractables and leachables: An Introduction

conditions including extraction solvent, technique, stoichiometry, temperature and duration. Extractables themselves, and/or substances derived from extractables, have the potential to leach into a drug product formulation under normal conditions of storage and use.

Leaching (chemistry) Wikipedia

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size.

Decomposition Process, Factors Affecting Decomposition

This process provides essential nutrients for plants and also for the growth and development of new organisms. A complete process of decomposition takes place in five different steps or phases: Fragmentation. It is the initial stage of decomposition. Fragmentation means the breakdown of detritus into smaller pieces by the detritivores. Leaching
