Why Switch to Homemade Laundry Detergent
Before I started using soap nuts to do laundry and homemade soap nut liquid laundry detergent, I made my own homemade laundry detergent after learning about the toxic chemicals found in many store-bought detergents.
In fact, a study done at the University of Washington found that the top-selling laundry products emitted nearly 100 volatile organic compounds (VOCs). VOCs are known to have a variety of short- and long-term adverse health effects, including headaches; damage to the liver and kidneys; eye, nose, and throat irritation; and even some types of cancers.

Additionally, every product gave off at least one chemical regulated as hazardous or toxic under federal laws. Yet none of these products had the chemicals listed on their labels.
That’s because manufacturers aren’t required to list ingredients in cleaning products, including laundry detergents and fabric softeners.
To protect your health, the health of your family, and the environment, your safest option is to make your own laundry detergent. Fortunately, it’s incredibly easy to do so with this recipe.

Fabric softeners and dryer sheets can have some of the same health concerns as store-bought laundry detergents. If you want to enjoy soft clothes without using fabric softener, add a cup of white vinegar to the rinse cycle and use wool dryer balls in the dryer.

Great recipe, could I use a natural homemade soap instead of castille soap? I live in Italy and not sure if it's available here. Thanks
