I make sure I use septic-safe toilet paper, and items that don't have nasty toxic fumes for cleaning products.

Am a label reader and some things that seem okay are destructive to our life support system (like palm oil; if it's not grown in a certified area then more trees are lost than what is being destroyed in the Amazon for beef production). That said a lot of things I use are locally made. Having a septic wouldn't seem like a problem but it is. Any chemicals in the tank can destroy the bacteria needed to break things down. Fabric softeners are the worst. White, distilled vinegar is the main thing I use for lots of things. It goes in the washing machine instead of fabric softener and I make dryer sheets with a vinegar soaked cloth with some aroma extracts. Absolutely nothing goes into the septic that is not natural. For those living on the land that is the most important appliance. Here, we are allowed to inspect our own tanks but one must take a course first.

I have eczema and the list gets bigger every year

Vodka is great!

no

I try to avoid anything with fragrance. Especially make-up, soaps, and personal care products. I don't understand why they would put those things in anything you have to put on your skin or near your nose or mouth.

I developed severe eczema because my body developed an allergy to the chemicals I work with so on the hunt for a new job and working hard to heal my skin. I was using a commercially available liquid soap but have since returned to my handmade soaps made in my kitchen. I was selling them but have been too mbusy as of late to make them but I think I will start back making and selling them. I make goats milk and mares milk soaps.
The reason these are better than commercially made soaps is very simple: Mass produced soaps have had the naturally occuring glycerin removed so they can use it in moisturizers that you will need to counter the drying effects of their soaps. Glycerin does not moisturize but rather creates a se al that prevents your skin from drying out.
