Tools and Tips

Researching a chemical in the news? Use the Hazardous Substances Data Bank and/or Household Products Database to learn more about the potential health effects, chemical ingredients in products and more. Check out this issue’s case study for search tips.

Case Study

In recent news, the U.S. Food and Drug Administration (FDA) issued a final rule which requires manufacturers to stop marketing antibacterial hand and body washes with certain ingredients such as triclosan and triclocarban.


You can use the Hazardous Substance Data Bank (HSDB) to learn more about triclosan. HSDB has a broad scope in human and animal toxicity, safety and handling, environmental fate, and more for over 5,000 hazardous chemicals. Here's a quick overview on how to search HSDB.


1. Type Triclosan in search Box Click on Search

2. See list of chemical records with information on Triclosan, Click on primary record Triclosan

3. Chemical Data

A. Table of Contents allows you to choose categories and fields for display

B. Chemical data is displayed (see human health effects)

C. View recent articles in PubMed

You can use the Household Products Database (HPD) to learn about other types of products that contain the ingredient triclosan. Here is a quick overview on how to search HPD.
