Increasing batch size and reducing mixing speed will help create less bubble

I prefer DMDM over DU+EDTA+Chlorphenesin or IPBC
-
What is the pH and what is the problem you want to solve?
I suggest you change the preservative.

In my experience cleaning a used bottle or pump of lotion is almost impossible.

Currently i am not able to edit my comments from mobile phone directory.
I use chrome Android.

What is your formula?
PE 9010 and EDTA may be enough.
No need for IPBC.
If you wanted to add another anti fungal, add sodium benzoate.

I think this mechanism only works against gram negative bacteria. And yes GLDA does this too.
-
Agreed with @fareloz
In one line of my products which are claimed fragrance free i add 0.005% fragrance enough to mask the unpleasant smell of product.

This is about efficiency of ECT.<div>

Interesting thing is that even unpreserved products pass the test in several of them. I don’t know why.

Looks like your problem is wiith fungi.
Maybe some IPBC will help.
@PhilGeis what is your opinion about this?
-
So we should use 0.15% tetrasodium EDTA to get 0.1% in acid form?

In desktop mode it has this edit option. Although the time shows different.

I just added this comment and as you can see it doesn’t have edit option.
Another problem.
It is June 15 6:47 AM now that i commented the comment time shows June 14, 2023 at 9:16 pm.

No.
I am not able to edit a comment in this new update for long time.
Most of the time it was not a problem but when you need it, it is a bit difficult to go to desktop mode, edit it and go back to mobile mode.
Some new users may think it is not possible.
-
That is a good point.
Thanks

?

Is slime & biofilm the same thing
-
Yes

Isn’t the free formaldehyde from releasers as much reactive as from formalin in the same product, package and condition?
If not why not? Both are free formaldehyde.
Those parts that are not free will not be reactive but they don’t do any preservation too.
-
Got it
As i am using formalin which is 37% formaldehyde, i wanted to know how it compares to these releasers.
For example instead of 500ppm DU i want to use 100ppm formalin to get about the same amount of free formaldehyde for gram+ bacteria. Is this a good idea?
-
Got it
Thanks
-
Thanks
To make sure i have understood it correctly, does the chart mean that with 0.49%, 0.3%, 0.46% DU, 0.02%, 0.02% & 0.06% formaldehyde was released?

@PhilGeis in this paper Table V and Table VI, diazolidinyl urea 0.25%+ CMI MI 3ppm failed for Candida albicans but diazolidinyl urea 0.125%+CMI MI 3ppm passed with A criteria in the same cream product. <div>
Any comments on why this happened?

Remove it

What is in the product?
Never mix with Tween 80.
Heating the product a bit or high shear mixer will accelerate dissolving.
You need something for gram+/y/m too.
