I think Xanthan Gum and Panthenol is less than 1% in first formula so your surfactant should be ≤1% too.
-
You need all of them. Add EDTA, reduce pH to at least 4.7 and increase benzoate to 0.5%.

I would use equal parts of EQ 65 and cetearyl alcohol to make high viscosity LGN without any other emulsifier or co emulsifier.
-
Use SPDMA

@Perry44 this data shows in hard water, more SLS was attached to skin compared to soft water. Does it mean even those soluble molecules from interaction of SLS and calcium can stay on skin or hair and cause problems?
-
Good
Thanks

@yyy thanks
@Graillotion you said dimethicone 6 cst. it is 0.5% dimethicone 5 cst. I am adding it thinking it is not volatile. Are you saying it is volatile?

Thanks

It is a surfactant solution.
What about formalin at that high pH for ~30 minutes?
-
Bothe have same amount of anionic surfactant and polymer
-
Thanks

Thanks. I will not add any preservative.
Just to know, is there any negative effect if i add any preservative in it?
-
Thanks

Do you know what was the article name from Dow?
-
Thanks

Thanks
So why that book says SLS is milder than ALS?
-
Then how sodium reacts with fatty acids?
-
If i add NACL to hard water, then anionic polymer, would chloride interact with calcium and then anionic polymer expand fully or not?
-
Thanks

Long time ago i was using it in shampoo at pH 5-7( don’t remember correctly) at 1% and it had no problem with SLES/CAPB at that ph. It was increasing the viscosity too.
-
Can’t open the article.
Can you send send it to me if you have it!
-
@ketchito thanks
How will calcium effect cationic polymer like cationic guar?
-
So isn’t the calcium in water doing the same thing?
-
Thanks

My pH is <5 and i use 100ppm piroctone olamine, 500ppm CHA, 2000ppm EDTA and 9400ppm phenoxyethanol. How preservative were you using?
@PhilGeis can i ask why 100ppm piroctone olamine would be a waste as preservative?
