It has often been mentioned that Dawn dish soap has formaldehyde in it and I often receive a response something like, “Surely not! Wildlife rescues use Dawn to wash wildlife after commercial oil tanker spills. I remember the commercials!”
Dawn Dish Soap is toxic because it contains harmful ingredients like Triclosan, 1,4-dioxane, synthetic dye, fragrance, and the dreaded methylisothiazolinone. These ingredients can cause mild to severe health conditions like nerve and liver damage, skin irritation, and allergic reactions.
You see, companies are not required to list all ingredients on personal use products, just industry level. Did you know formaldehyde has about 14 different names? If you research, you will see methylisothiazolinone and Methylchloroisothiazolinone are both forms of formaldehyde.
Many dish soap brands have labels that state the product is “biodegradable” with Methylisothiazlinone and Methylchloroisothiazolinone listed as ingredients. If you are, like me, are allergic to formaldehyde, you may want to make certain you are avoiding that these chemicals to prevent skin reactions.
Dawn soap is also toxic to wildlife, especially the aquatic community, because it poisons the water. This liquid cleaning agent contains 1,4-dioxane, a substance renowned for polluting or contaminating the water.
Methylisothiazolinone is highly toxic for freshwater and estuarine organisms. Dawn also contains plenty of other dangerous chemicals. Pei-14 PEG-24/Ppg-16 Copolymer has links to cancer, organ effects, skin irritation, and damage to your vision.
Even the company EWG, which allows companies to buy good ratings, give Dawn a D rating!
That’s why I threw away all my Dawn and switched to Lemon Brite, because I want to ensure my family’s health.
