For me Biz was SUDS, SUDS, SUDS!! Insane amount and long lasting. 3 rinses and the water was still full of suds! :(

I think sodium carbonate works with whatever detergent you use to make it "better". I guess the result is lots of suds.

Sodium carbonate is great in small amounts, but its in powdered detergent already, and when additives are used with it in their ingredients, it can be very hard to rinse out causing scratchy, stiff clothes. Maylingsmom, thank you for listing the Biz ingredients % ...40% sodium carb doesn't please me, all the more reason I need to order sodium percarb online...but actually that 40% is about average for sodium carb in store bought additives. Lol..is there sodium carb in liquid detergent? ? Seems to me its just in powders, I'll have to look.

I think sodium carb is in powders and borax is in liquids

I don't know about the liquids you can buy but the recipes for homemade liquid detergents often have sodium carb in it.

Ya I tried that homemade once upon a time lol...but I don't think sodium carb can be used in manufactored detergent. ..I think it loses its effectiveness .

I ment sodium carbonate isn't used in LIQUID detergent, I think it dies in liquid . Lol

Are you sure sodium carb dies in liquids? So how does it work when you add powder to water? I don't think I am following your line of thought.

Maylingsmom, I'm trying to remember where I read this and I guess I tended to believe it as I don't think liquid detergent has sodium carbonate, I actually think that's why liquid tends to make clothes feel softer, not scientific but my thoughts since sodium carb can make fabric feel rough if too much is used. As for your question, no I'm not sure, just something I read. I'll have to check ingredients in liquids to see if any have sodium carb. ..hmm now I'm curious. Do you know of any liquid detergent with sodium carb?

I was just wondering why the water in the washer wouldn't make sodium carb in powder die since you said that it dies in liquids.

This is driving me insane where I read this, but I don't see sodium carbonate in p&g liquids or wisk. I could of course be wrong about sodium carb and liquids dying however there must be some reason its not in liquid detergent, and i'd like to know why lol

Maybe someone over on aw knows why.

Maybe..I'm gonna ask lol

Ok maylingsmom, sodium carb doesn't die in liquid detergent. Closest I can tell from over on AW its not in liquid detergent because it isn't needed in it. But interestingly it is in some of the cheap liquids that don't contain enzymes. I do know sodium carb is in powder detergent I'm not against that and powders are my choice. I just hate adding more. I read where A&H powders have up to 85% washing soda that's a lot.

Sodium carbonate is a "builder". I have been reading tons of stuff about it and they all say pretty much the same thing. It is used to make all the other ingredients in detergent work better.

Sodium carb raises the PH enzymes in liquid detergent are designed to work at a ph of 8.5 anything higher will render the enzymes ineffective. Thats why washing soda isn't in liquid detergent with enzymes. Nothing wrong with washing soda, its when its used in excess that it becomes a problem. Heck there's tons of it in powder detergent and that's my go to. I hope you haven't misunderstood my view on sodium carb..it is a builder and powders definitly need it.

Maylingsmom..are the ingredients listing 40% sodium carbonate by weight..lol

Yes, but it said < 40% so who knows exactly how much that is.

Stan over on AW said biz is 19 percent sodium carbonate last he checked..but the <40% by weight could =19% since its going by weight and sodium carbonate weighs more than sodium percarb. If that's the case than that's perfectly acceptable to me. Ya know I use Biz because of the sodium percarb I keep saying I'm going to order a more pure form online which I should just do.lol..I bought a small tin last week of Nellies oxygen booster, I found it on clearence at TJMaxx for 3 $ it whitens like you would not believe, but leaves everything so stiff requiring a 2nd rinse...decided I'm going to bag it up and donate it to the animal shelter, but they can not have the tin lol.

I guess what Stan is saying might be by volume. But I'm no mathematician so don't go by what I say. :)

Biz must be pretty good because it has tremendous sales.

Have you never tried Biz?? It is very good, IMO way way better than oxiwash additive. I'm no mathematician either lol..
