The goal of the project is to curate and disseminate information about excipients, the assumed-inactive substances found in food and drugs. This includes: colors, flavors, stabilizers, bulking and delivery agents, fillers, packaging, and other purposes. The excipients browser and the database behind it are free for everyone to use, but you may not copy or redistribute major portions of the database or its user interface without the express written permission of John Irwin, chemistry4biology at gmail.com.
