Washing with eczema

[Tj20]

Hi can anybody advise how much persil non bio washing powder to use for each load say a half 5kg load and also a full 10kg load, light dirt in a soft water area. And how many extra rinses would be needed to still be fresh but no residue or strong detergent smell.

I’ve always found Persil, Ariel etc terrible for our skin - we’re all sensitive, psoriasis, eczema etc. Fairy is pretty good. Smol is great. Boots do a special sensitive powder. But I would avoid Persil.
Always use minimum amount and put an extra rinse on.

We can only tolerate fairy non bio and I use about a tablespoon per wash, maybe even a bit less.
Also DD can only use childs farm hand wash/shampoo or bio d hand wash at a push.

I find liquid better than powder and do use much less than the recommened amount.

Thank you for your replies, can anyone tell me extact amount as in Milliliters to use for 5kg load and say a 10kg load. I am really struggling at moment with ocd and paranoia of my clothes being soapy and smelling strongly and then being itchy. I don't want to go down the route of unperfumed as until now always used persil no problem until this ocd kicked in.
