Ingredients in Homemade Soap vs Store Bought
Making the switch to homemade laundry detergent has been a game-changer for my family. We can actually see the difference in the ingredients we're using.
The first thing that stood out to us was the lack of fragrance in our homemade detergent. Unlike commercial detergents, which can contain over 3,500 different ingredients to create their signature scent, our homemade recipe uses natural alternatives to leave our clothes smelling fresh.
Dyes are another area where commercial detergents often fall short. We've found that many store-bought detergents contain dyes that can cause skin irritations and even carcinogens. By making our own detergent, we can avoid these potentially hazardous chemicals altogether.
Phosphates are also a concern in commercial detergents. These additives can pollute natural bodies of water, which is a major environmental issue. Our homemade detergent recipe avoids phosphates altogether, making it a more eco-friendly choice.
Here are some of the questionable ingredients found in commercial detergents, along with their potential risks:
- Fragrance: can contain hazardous chemicals, including carcinogens
- Dyes: can cause skin irritations and potentially carcinogenic effects
- Phosphates: can pollute natural bodies of water
By making our own laundry detergent, we have complete control over what goes into our clothes and the environment. It's a simple change that's made a big difference for our family.
