I guess it is Glyoxylic acid which comes as 50% solution and is being used as an alternative to formaldehyde based straighteners. 

[Chemist77]

Check PMX 1505 which is based on isd only, has great compatibility with most so of the commonly used cost effective emollients including paraffin oil. 

[Chemist77]

Aculyn 88 from Dow should do that and the surfactant compatibility is excellent. Dosage will be based on type of beads you are trying to suspend.

I have seen a beautiful peal effect but in SLES/CABP/APG system. I used at 1.5% along with CMEA in same ratio, works out fine every time. pH is around 5.4, ASM is around 15%.

Happy birthday Perry (belated).
Thanks for creating a legacy that many benefit from. 

[Chemist77]

Aqucar GA 50 could be the alternative then, still not sure about USA though.

[Chemist77]

As @Abdullah pointed out, way too much LABSA and SLES. Cut down to half and then do what has been suggested. Mg Sulfate might help in clarity but this happens where certain polymers are used to build viscosity. I don’t use polymers or Mg sulfate. For preservative, I stick with Aqucar IG 50. 

[Chemist77]

@chemicalmatt absolutely bang-on on clarity and marketing peeps. I have had a chance formula where I combined Carbomer 940 with a Dow polymer called Aculyn 88. I used 3% of PVPK 90, the gel is amost like a glue in hold but clarity is a big turn off for prospective customers. Do you think this will be inherent as we combine 2 different polymer chemistries or PVP K90 could be causing the issue. Though I have done without fragrance and PVP too, not much success on clarity. 

Any thoughts??

[Chemist77]

You need an alkali like a sodium hydroxide to neutralize the acid to form a soap. Adjust the pH around 7 & and above, should be fine. 

[Chemist77]

@chemicalmatt I do prefer AMP-95 to TEA although price difference is huge. Do you think neutralization of Carbomer 940 with AMP-95 compared with TEA or any other alkali will produce a better gel in terms of a typical gel property. I mean hold, clarity, etc.

[Chemist77]

Acusol 882 (Dow) is one of the best known for such formulations, stabilizes as well. 

[Chemist77]

Try a sample without fragrance too, who knows???

[Chemist77]

In food what I generally see is a combination of KSorb/NaBenzoate along with other factors like low water activity, low pH (in ketch and sauses), high sugar content, etc. Again I believe the PET should be done no matter what the area of use is, more so in this case as it is an intimate care product. 

[Chemist77]

Gunther they all the same issues more or less. Viscosity on lower side and sticky after feel in certain Aculyns. 

[Chemist77]

Any idea where this product is going to be used, I mean area of use on the body.

[Chemist77]

This was a great article @chemicalmatt for many of my customers who kept on falling for wrong calculations. 
Fantastic stuff. 

[Chemist77]

Actually you could use those ones that you have in stock as the ultrez solution I believe will be non-neutralized and hence pretty acidic. But again once you neutralize the solution to make the sanitizer, the viscosity won’t be as much as it should be as those preservative salts would be detrimental to the viscosity neutralized gel. So in this scenario, I would stick to what Perry and Dr. Bob have mentioned. 

[Chemist77]

Yeah Gunther it will, I ran a trial with IPA as well and it came out pretty good and clear. Viscosity is on the lower side compared to carbopols. 

[Chemist77]

We have done such formulations but that is a very high ethanol content. It will not allow any surfactant to foam, I have seen around 5% IPA in such formulations but not that high. Also HPMC will work better for a clear formulation, check Methocel 40-202. And don’t expect this to foam like a normal high foaming soap. 
Plus stick to what Gunther has suggested as these formulations are used in the hospitals extensively. 

[Chemist77]

Sanitizer all good, leave aloe out honestly. 

[Chemist77]

Junaid follow what Bill has recommended, you cannot make peroxide containing carbomer gel. Remove it and try Ultrez grades which are generally used for sanitizers. Though no restriction if you can manage with 940 grade and for neutralisation TEA 99%, AMP-95, etc. can be used. Search this forum and you will find many discussions and finished formulations. 

[Chemist77]

Generally I have seen around 1-2% in such sanitizers and could be contributing to the stickiness. 

[Chemist77]

That’s the recommended ratio as posted by many here, check the Lubrizol sheet on neutralisation ratios. 

[Chemist77]

I have found UCON fluid 75-H-450 to be helpful in reducing the stickiness of such formulations, say @0.5-1%. Also that’s an extremely high dosage of PG, you could reduce it to 1-2% or another option would be PEG-400 as I have seen people using this to reduce the stickiness. 

[Chemist77]

And remove the IPM too, it will keep floating for nothing.
