Paw..if yours disolved when stirred and is clear..well that's what it should do.

Sandy I think it has to do with density...ill post a response to this I ask on AW a good while ago..I'm actually going over later to talk about these issues

Now Sudsmaster is a pro on STPP he could write a book..he's also the one that wrote about STPP in our FAQ. whatever he says you can bet is accurate.

I'll go over later and try to ask him about these issues

I tested mine from ProSupply in warm water and it's crystal clear.

I have mine stored in one of those tall soup containers that seal fully.

I sniffed my STPP and it actually has a slight fresh scent.

My STPP went to the bottom of the wine glass and when I stirred it looked like fine powder swirling around and in minutes was fully dissolved.

And the water felt slippery.

well.... this makes me wonder if I actually got what I ordered, STPP?..... I got mine from Dafna about a month ago also. I have not been over the top impressed with it at all and found the loads of laundry I used it in came out feeling stiff and I'm only adding one TBS in a front loader. After reading everyone's posts here about amazing whites, old stains coming out etc... I just haven't found that to be true for me. I did make the mistake once of adding it in with liquid detergent and it made a big chunk of what looked like hard plastic. It does seem to be dissolving in the dishwasher and I'm not quite sure how other's add it to the dishwasher if you use liquid dishwashing detergent? I am off now to smell mine....

STPP should never make clothes stiff...it binds everything up and prevents it from redepositing onto clothing..its sure won't cause stiff clothing if enough is used to condition the water.

This is a mystery for sure.

Debbie can you drop a dpoonful in a glass of hot water..stir a few times and report back what happens? Thanks

Listen up folks...those of you that are getting a hard crust from your STPP stop using it until we know what's going on.

And I'm grateful to our Recordaras for bring this to our attention. Something is for sure wrong. I know I have always ordered from Dafna for several years and I play around with this stuff too much for it to have happened in the past to me. But my lastbag from a month or so ago wasn't yet opened or I may have caught this.

I posted a message to Sudsmaster on AW and I'm sure when he has the time he will give his advice. I'm also waiting a response back from the Dafna General Store. I Emailed them last night and called an hour ago..of course someone will return my call lol. Hang tight.

Sin...what's your take on this??

Mich???

NO response from Sudsmaster yet but I got this...Sin watcha think?

Just tried this myself in a glass. It doe not completely dissolve. The heavier particles sink to the bottom of the glass. ohhhh the poor drains collecting this crap.

I ordered some from them on November 2 . When I stuck my nose right inside the plastic container, I smelled a very very slight antiseptic smell, but I don't think you would notice any smell if you didn't do that. I put one tsp. in a coffee cup of just boiled water and it immediately dissolved. 10 minutes later it is still crystal clear.

Grapeleaves, long time since you've posted here..good to see you. I wonder if yours would still disolve if it wasn't boiling water. Yes I huffed mine good and there is a very slight not unpleasent scent.

Interesting, I just had an STPP issue/question also. I opened a factory-sealed container that I bought from Chemistry Store in 2014. It looked different from what I've gotten from them before (finer, with some clumps), and also smelled different. I emailed Chemistry Store and didn't get an answer. Then I bought 5 lbs. from Dafna on Amazon, and received something that's similar to the 2014 Chemistry Store order I just opened. So it probably is STPP, but different from what I've used in the past. The Chemistry Store containers give me a bit more confidence than plastic bags from Dafna, but I think rpsinfoman is right either way. I haven't taken chemistry since college over 40 years ago, so what am I doing buying chemicals that I don't really understand.

Well you probably understand the principal of phosphates in laundry. .but that doesn't mean any of know by the look, feel and scent if were actually getting what we've ordered. I guess that would depend on how much trust we have in the company were ordering from. Phosphates (STPP) is cheap to manufacture, so I think either some dummy in the warehouse can't read the labels on the drums...or it was processed wrong. Either way this falls on Dafna to fix this issue since it was from them we bought it. Hopefully this can be resolved.

1 TSP in 8 oz. tap hot and it dissolved and water is clear

1 TSP in luke warm and it also dissolved and water is clear.

Thank you Grapeleaves, sounds like your is probably fine.

yes, I think so. I'm glad that I didn't waste the money:)

Ok mamap.... Here you go. It's hard and chunky in the bottom of the jar and this is hot tap water....well for some reason It won't load the photo on my phone will post the pic when I'm back on the computer

Here is the pictures... It looks exactly like recordaras photo above, I could break it up with a spoon but it never dissolved.

I would lile everyone that has STPP only from Dafna that is turning hard and crusty lis an approximate date that you received it..just the month needs to be accurate. THANKS and I'll start. This can be helpful pinpointing about when this started...

October 1st 2015

Should it dissolve immediately without stirring? Mine settles to the bottom too unless I stir it just a couple of times and then it is totally dissolved.

I got mine from Dafna. Order processed on 10-22-15. This is the quote from my confirmation email:

" Sodium Tripolyphosphate sodium-tripolyphosphate-light-density "

I got mine 25th of October. I did stir what you see in the above photo and it was hot tap water. It did not dissolve at all, just settled to the bottom and became hard fairly quick

Ordered September 24th, 20lbs. Dissolved almost instantly in warm tap water.

Dafna Automotive is an industrial producer of auto detailing products. Apparently they also sell off some of there raw materials directly and through the Amazon outlet. Without knowing where those raw materials have been sourced from, the quality, density, and shelf life, you really don,t know what your putting in your washer, sewer lines, and residuals in your clothing. This is a dangerous practice we all engage in looking for the old fashion phosphate based detergents. The other problem is adding phosphates to modern chemically engineered detergents could be counter productive. Detergents of today have been engineered with replacement conditioning agents to replace phosphates. Adding STPP back to the modern formulas doesn't necessarily guarantee they will be chemically compatible. I also think if your purchasing STPP, DO SO FROM A CHEMICAL SUPPLY STORE. You may pay more but at least it offers a degree of comfort your getting the actual product.

I have ordered 2 batches from Dafna, and both did exactly what everyone is showing - didn't dissolve in a glass. Here's my order info:

Ordered 08/06/15, delivered 08/10/15 - 2 lb.

Ordered 10/01/15, delivered 10/05/15 - 5 lb.

Lot of truth in what Sin says....But I've ordered from Dafna for several years and The Chem Store.. I never noticed a difference in the STPP from either place. They both looked, smelled and felt the same..and wet they both looked felt the same...no I think up until my last batch I was getting STPP now I don't know what this is. BUT its for sure NOT my beloved Phosphates. Well I could be I guess the poster above from AW could be correct and a step was missing in formulating it but than it would make this what??

IMO going by what I've learned from Sudsmaster STPP is fine to use with modern day detergent, isn't Sodium Carbonate the main ingredient that took phosphates place...and I know STPP binds that up so to speak and holds it in suspension to prevent residue. ..

I have to get to the bottom ofthis crappy stuff...iI'll call Dafna back today.

Hmmmmm-now you all have me wondering about my STPP! I ordered it from Dafna about mid October or so. It certainly seems to be working just fine--like MAGIC, in fact. I haven't noticed any residue at all.

I'll try the teaspoon in warm water test when I get home--we are in Arizona for Thanksgiving right now.

MamaPinky--I'll be interested to hear what Dafna says when you call them today.

Out of curiosity, I stuck my nose down into the 5-gal bucket of STPP that I got from ChemistryStore.com maybe four years ago. It smelled like nothing, except the airtight plastic bucket it lives in. I can pick up on perfume scents from a few feet away and am particularly sensitive to chemical smells. I hope the Dafna situation gets worked out.

Maybe a bad batch from there supplier or old product that was improperly stored. I've bought from Dafna and haven't had a problem in the past. But then again they could ship me any white powder and I wouldn't be able to tell you what it is.How would actually test STPP to determine its validity?

None of my STPP ever had any scent in the padt.

Sin I haven't a clue how to test it unless you use a water tedt strip and test for hardness and than tedt again after adding the product.. but that probably is a lousy way to DX because lets say it was sodium carbonate. .that in itself would change the test strip somewhat. I recieved a email let me try to post it

THis must have been here a few days I foundit in my spam folder

So now I have to pull my box of TSP out and see if the stuff turns hard and crusty..give me a few

My STPP is Scentless also. The TSP I have does have more of an insoluble grit. If it's exposed to moisture it becomes like a rock. I pretty much relegate it for heavy duty garage shop and concrete cleaning. I also thought STPP not stored properly and exposed to moisture breaks down to TSP. I really don't know. We need a chemist. Lol

My STPP from Chemistry Store always smelled sweet to me. Maybe other people wouldn't detect any scent in the same sample.

Yes I have the stuff in the garage..but I think TSP will disolve instantly..so I doubt our new batches are TSP..I don't think though Dafna has duped us..I have a feeling they got a bad product maybe as someone on AW said..it was processed wrong. Theres quite a few over on AW that order from Dafna and these guys are picky to say the least I think one of them would have advised against this company, I think this is a new issue probably in the past 2 months and I think Dafna will make good on it...after all too many here has this issue so their reputation is on the line. I don't think for one second they are adding fillers. STPP is very cheap so there would be no reason to add fillers....either they got the STPP that was manufactured wrong..or some dumb ass working in their warehouse labeled the large drum wrong...the latter is what concerns me. I know we can't threaten them with news media LMAO some states don't allow phosphates even if your adding them yourself. My mini test is done..1/8'th cup TSP in tepid water, 10 stirs it was very foggy but turned crystal clear in 30 seconds..no hard crusty clumps only a few tiny grains settled on bottom of glass....so TSP also disolves instantly...strange that this stuff would be crystal clear. What I need to do next if find out what chemicals Dafna sells that is white..we can than probably narrow it down to knowing its probably one of these...later...my bird need basting

I just sent Dafna an email with my order number and a request for a refund. If I am out the money, so be it, I wont order from them again. But Mamapinky's email is promising. Thanks for that Mamap.

testing my new toy

ok sorry i bought a new Tablet with keyboard and thought i forgot my password

My STPP was ordered from Amazon on 9-28-15, so I might be on the good/bad threshold. I am traveling and cannot do the smell or hot water test but will on Sunday. I will say this -- when I use it to hand wash, the water feels like liquid silk. Does that tell me anything?

Thanks, mamapinky, for the tip not to mix liquid and powder in a dispenser. Being new to FLs, I was unaware. Do you think the fact my STPP crystallized in the dispenser can be taken to mean it was not STPP? Or can it be attributed to solely to user stupidity?

Lizzie there's no way to know if its real or not until you get home and do the glass test, but liquids and powders mixed together in the dispenser reguardless of what it is will probably do this. I would put the STPP directly in the drum with the clothes to prevent this.

Hey guys, so just an update - when I posted this last week I ordered a couple of bags from ProSupply and wanted to take comparison photos when they got here. Today the package was delivered and...

10 lbs of Tetrasodium Pyrophosphate!

I seriously have a feeling that the universe is telling me to stop experimenting with this stuff, haha. ProSupply were great - I specifically asked for a return label when I reached out because I do not have any room for another 10 lbs of unwanted chemicals! They sent me the label right away and shipped a replacement.

What is that stuff?

It sounds similar to STPP..from what I can google.. it's better for high magnesium in the water, where STPP is more of a balance with Ca and Mg. It's used more in liquid detergents as it appears to be more stable. Good news is that TSPP and STPP work very similarly in yield and flavor enhancement for reduced sodium hot dogs...

I am inclined to believe a lot of these preparations are designed to correct specific water conditions, this one in particular if the supply is high in magnesium. Depending on your water supply there may not be any benefit from using any of it. They are all water conditioning agents, which may explain why there are so many variations when placed in water.

Been reading up on all of this STPP stuff! Sorry everyone has been having problems but also glad Dafna is making it right! (and ProSupply too, recordaras!)

Jean you do disappear frequently lol.glad to see you.

STPP does more than just condition or soften water otherwise I wouldn't bother with the stuff since my water runs at between 0gr/gal to 1gr/gal depending on time of year.
