I know which brands are the worst for me. However, for people who don't have allergic reactions, sometimes it's hard for them to believe that their laundry soap is highly toxic.
So here is a good resource that has an objective scoring system for laundry detergents, based on the known ingredients in them (not all products disclose all of their ingredients, which is also concerning). The scores are on an A - F scale (A being the best and F being the worst).
I wasn't surprised that many Tide products had an F score. And I was thankful to see that the Charlie's Soap had an A score. (That's the brand I've used for several years now.) I was surprised that there are so many laundry products and brands (hundreds).
Here is the link to the list of general laundry detergents. You can search for a specific brand, or view the products listed for each grade.
I hope this resource will be helpful for your own shopping choices, as well as for when you want to share facts with others about certain ingredients and the known dangers of toxins.
Laundry products are potentially so harmful because they get in and stay in our clothes that we wear 24/7, in our sheets, towels, etc. That's why it's very important to use products that are as non-toxic as possible.
By the way, out of 180 fabric softener products reviewed, only 13 had an A or B score. Here's the link to see the information about those:
Let's keep up the good work of making healthy choices and encouraging others to as well. =)
