Why Use Natural Dish Soap?
Switching to more natural, eco-friendly dish soaps is an excellent choice. Conventional dish soaps, especially liquid ones, contain a host of chemicals that are not only bad for our health, but the environment too.
From solvents and surfactants to synthetic fragrances, preservatives, and caustic ingredients, they’re laden with substances that harm everything from how our hormones and immune systems function, to aquatic life and water quality.
Take a look at this video by EcoMastery Project for a snapshot of what is the dish soaps and detergents we use every day:
Conventional liquid dish soaps and detergents are also mass-manufactured in ways that harm the environment and come packaged in tons of unnecessary plastic!
Thankfully, there are some great solid dish soap bars that are thoughtfully made with natural, non-toxic ingredients and come in plastic-free, zero-waste packaging!
They’re also super effective and work just as well as conventional liquid dish soaps – without any of the harmful chemicals, and no waste. What’s not to love?!
