AOAC 99120 Residual Solvent Testing in Waste Products
The AOAC Official Method 991.20 is a widely recognized standard for detecting and quantifying residual solvents in various products, including waste materials. This method ensures compliance with safety standards set by regulatory bodies like the U.S. Food and Drug Administration (FDA) and the European Union's New Approach to Chemicals Management (REACH).
The process involves the extraction of target compounds from a sample using solvents followed by analysis via gas chromatography. This technique is particularly crucial in industries such as pharmaceuticals, agrochemicals, and cosmetics where residual solvents can pose significant risks if not properly controlled.
Our laboratory adheres strictly to this procedure, providing accurate and reliable results. The methodology encompasses detailed steps for sample preparation, extraction techniques, and chromatographic analysis. Our team ensures that all tests are conducted under controlled conditions using calibrated instruments.
The importance of residual solvent testing extends beyond mere compliance—it also plays a vital role in protecting the environment by ensuring that waste products do not contain hazardous chemicals that could leach into soil or water during disposal processes. By identifying and quantifying these compounds, we contribute to safer recycling practices and more sustainable waste management strategies.
Our approach focuses on delivering consistent, repeatable results across multiple samples, allowing for effective monitoring of production processes or post-consumer waste streams. This consistency is achieved through rigorous quality control measures throughout the testing lifecycle—from initial sample receipt to final report generation.
Benefits
Implementing residual solvent testing in waste products brings numerous advantages, both for manufacturers and environmental stakeholders. Firstly, it enhances product safety by ensuring that residual solvents are within acceptable limits as per established guidelines.
Secondly, this testing supports compliance with stringent regulatory requirements, thereby reducing legal risks associated with non-compliance. Moreover, it promotes responsible waste management practices which are increasingly important in today’s sustainability-driven marketplaces.
Additionally, such tests enable companies to optimize their recycling processes by understanding the chemical composition of different types of waste streams. This knowledge can lead to improved resource recovery rates and reduced costs related to waste disposal.
For research and development teams, residual solvent testing provides valuable insights into how residual solvents behave under various conditions, informing future product formulations and process improvements.
In summary, implementing AOAC 99120 ensures safer products, compliant operations, optimized resource use, informed R&D decisions, and ultimately contributes positively towards sustainable practices.

Use Cases and Application Examples
In the pharmaceutical industry, AOAC 99120 is used to ensure that raw materials meet strict quality standards. For instance, when manufacturing synthetic cannabinoids or other novel psychoactive substances (NPS), it's essential to verify that any residual solvents are below permissible levels to avoid potential health risks.
In the agrochemical sector, this method helps in assessing the safety of pesticides and fungicides after they have been used on crops. By conducting periodic analyses, farmers can ensure that no harmful residues remain in the soil or plant tissue post-application.
For cosmetic companies, residual solvent testing ensures product integrity by preventing contamination from solvents used during formulation stages. This is especially critical when dealing with highly sensitive skin care formulations where even trace amounts of certain chemicals could cause adverse reactions.
