When rubber is exposed to acetone, several chemical reactions can occur. Acetone can act as a solvent for many types of rubber, leading to significant changes in the rubber's physical and mechanical properties. For instance, natural rubber, which is primarily composed of polyisoprene, can swell significantly when dipped or soaked in acetone. This phenomenon occurs because acetone molecules penetrate the rubber matrix, disrupting the intermolecular forces within the rubber. As a result, the rubber may lose some of its structural integrity, leading to deformation or even permanent damage.

One of the primary concerns surrounding residual solvents is their impact on drug safety. Many of these solvents have been linked to serious health risks, including carcinogenicity, reproductive toxicity, and organ damage. As such, regulatory agencies like the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have established stringent guidelines for the permissible levels of residual solvents in pharmaceutical products. Compliance with these guidelines is essential for manufacturers to ensure that their products meet safety standards and gain market approval.
