Do it yourself!
Making your own laundry detergent is better for the environment and can save you money.
There are dangerous chemicals found in your average laundry detergent like phenols and synthetic surfactants.
Phenols are toxic chemicals that can cause damage to your lungs, heart, and kidneys and liver. I don’t mean to be a downer, and I’m not saying that if you use commercial detergents you’re going to cause serious harm to yourself. BUT, phenols are easily absorbed into the skin and can be harmful to those with highly sensitive skin.
Surfactants are substances that bind oils and wash away in your washing water. Natural surfactants are safe for people and the groundwater, but synthetic surfactants are not. Synthetic surfactants are found in a lot of commercial detergents.
All in all, making your own detergent is better for the environment , cheaper, and better for your health.
