Most people use around 10 personal care products every day with an average of 126 unique ingredients. We'd like to believe that the government is policing the safety of all of these mixtures we're putting on our bodies, but they're not. Instead, these under-regulated chemicals are causing concerns for human health and the environment - whether they seep through your skin or wash down your drain.
How to read a label
Every personal care product on the market must list the ingredients on the label. Label reading can be confusing - here are some tips to help you wade through the chemical names. You can approach ingredient lists in 3 parts:

1. Start at the end where preservatives are listed. Try to avoid:
   
• Words ending in “paraben”
• DMDM hydantoin
• Imidsazolidinyl urea
• Methylchloroisothiazolinone
• Methylisothiazolinone
• Triclosan
• Triclocarban
• Triethanolamine (or “TEA”)
2. Next, check the beginning of the ingredients list. Here you’ll find the soap, surfactant, or lubricant that has been added to make the product work. Try to avoid ingredients that start with “PEG” or have an “-eth” in the middle (e.g., sodium laureth sulfate).
3. Finally, read the middle ingredients. Here you’ll look for some common – but not essential - additives that may bring excess hazard: fragrance and dyes. On the label look for “FRAGRANCE,” “FD&C,” or “D&C.”
