thicken agents for low ph product
so i have limits with carbomer and hydroxyethyl cellulose . obviously carbomer not usable at low poh .
trying to make a product similar to Neutrogena Tsal %3 sal ( ph is 3.5 ) and Is like honey
Neutrogena used hexylene glycol as only thickener I see but cant find it anyplace. my ph is 3 as im at %4 SAL . and cant get it thick enough
The inactive ingredients are water, sodium C-14-16 olefin sulfonate, cocamidopropyl betaine, linoleamidopropyl PG-dimonium chloride phospatem, hexylene glycol, polyquaternum-22, sodium lauroyl sarcosinate, and sodium citrate.

carbopol ultrez 30 works from pH 4 according to Lubrizol.
Why is hexylene glycol hard to find for you? It is a very common chemical, you can even find it on Amazon. -
Well, I just this minute prepared a new formula with pH at 3 to 3.5 and thickened it without problems using Glucamate LT.
-
only place I seen it is sigma Aldrich 500g 50 .00 Glucamate LT 32.00 a pound and is easier to find so I will try that first thanks
-
HEC works even with strong peels.
-
hexylene glycol will thin formulas rather than thicken them - and as there’s no obvious thickener in there, I believe that ingredients list is incomplete
agree with @Zink‘s suggestion of HEC, and I’d add one for xanthan gum too - I’ve seen that used to thicken hydrochloric acid toilet cleaners with a pH of 0 - 1, so it shouldn’t have a problem here
-
The blend of Sodium C-14-16 Olefin Sulfonate and Cocamidopropyl Betaine can be thickened with salt. No additional thickening agent is really required.

Try Amaze XT with Xanthan gum

well bill you are correct after I purchased said product listed as thickener I read I t was a thinner , sure nuff just .5oz of hexylene glycol turned a half gal of semi thick shampoo into water , will try the xanthan gum , believe I tried it in past and I t made product hazy but ill take thick over appearance . already had used what perry suggested but when I get to 4ph it thins out . im shooting for 3 to 3.5 as the Salicylic acid goes from %90+ at 3ph to less than %10 availability at 4 .
anyone know if “carbopol ” is same thing as carbomer 940 ? makers of carbopol claim works to ph 4 but ive tried the carbomer and same issue at ph 4
thanks for all input let ya know what works best
-
oh BTW HEC gives me separation issues trying to get it thinned out prior to mixing as it separates to surface any suggestions
-
Carbopol 940 is a carbomer and will not work at those pH values.

DING DING DING it looks like neutragena TSal inactive ingredient list is incomplete as bill said . I just received a bottle of the Glucamate LT per belassi suggestion and guess what ? same color, consistency ans SMELL as the TSAL product looks like the main ingredient by volume is Glucamate LT .
thanks again all

(Laughing). Glucamate has really nice sensorials. If you want even thicker or to use less, Glucamate VLT will do that.
-
Purpose of using Hexylene glycol in Neutragena is to solubilize Salicylic acid. It act as a solvent here. I do agree with Belassi, Glutamate VLT and DOE thickeners from Lubrozol are good options for this. I worked with Glutamate range, got good results. But, if product is over thicken, it would form lumpy gel. Its needed to keep flow able viscosity in case of Glutamate.

I had problems thickening a cleanser with low pH (salicylic acid) . I think we ended up using Aqua SF-1.
-
Yes, Ashish. It’s not a linear relationship, I noticed that I have to carefully adjust each batch by hand, a little too much takes it to something more like plastic flow.
-
Aqua SF 1 will form turbid gel below 6.
-
@ashish in our case it was not a clear product. It is a cleanser with EGDS for pearl.
