Biodegradable Detergent Information
The vast majority of detergents, particularly the brand name detergents, are not biodegrable. They contain chemicals such optical brighteners, dyes, artificial fragrances, and a number of other non-natural ingredients. You can read about this in more detail in our laundry detergent ingredients article. In general, if the ingredients contain words like "ionic and non-ionic surfactants" you can be sure it is not truly natural, eco-friendly detergent.
We can suggest several makers of biodegradable laundry detergent:
1. Seventh Generation, http://www.seventhgen.com
Not only do they carry several types of laundry detergent, they are also an excellent resource for learning more about laundry detergent ingredients and their effect on the environment.
2. Sun and Earth, http://www.sunandearth.com
Their price is quite reasonable and their products have a really nice citrus smell.
3. Ecover, http://www.ecover.com
4. Ecos, http://www.ecos.com
5. Charlies Soap, http://www.charliesoap.com
Their laundry detergent outperformed Tide in Clemson University tests.
