Yes that is for sure, mine luckily is pearlized and opaque so there I am saved. OK here you go then, it might help you possibly.
-
Continuing with @Belassi observation I have observed that my non-ionic creams behave a little less thick with the incorporation of ceteareth-20, you could drop that too if possible and see the effect.
-
Why don’t you try Aqua SF-1, I am using it in my sulfate free system and it thickens pretty good and the back acid thickening too works absolutely wonderful. If you need further info I would send you my formula and you can tweak it as per your need or adopt the same. In fact the yield value too is great as I am adding some pearls too ( that was a weird request from customer so I just toed the line).

@pepe Since salt is generally a part of Betaine I was thinking more on that line that it has been mentioned as a part of betaine. And of course the function which you mentioned and which is inherent to salt for surfactant systems.
-
I agree with @Bill_Toge, I have had the same issues with this thickener. Bought a bag of 25 kg a year back and yet to finish it, even for sulfate systems I never liked the thickening it provided.
I have used Rewoderm LI S80 but not sure if it can help you in sulfate free system. -

I absolutely concur with @Bobzchemist, sorry since we have a chemical CM 1000 as gum dispersion as well from Belsil I got it wrong.
-
@Priya Is that Isopropyl Alcohol which you have mentioned as IPA???? And why the silicone gum??? I suggest you again go back to the supplier for that special grade PJ and try to optimize it the high MP waxes. Btw what is HP wax??? Polyethylene or something else????
-
@Priya maybe you have to ask your PJ supplier to give you a grade which can sustain higher temperatures plus the EOs or you could optimize using some paraffin/ozokerite/microcrystalline/ceresin which all are petroleum derived waxes.
-
How about HPMC for an all COLD process, thickens better and provides a good freeze/thaw stability.
-
@Bobzchemist Absolutely correct about the last para, my company bought a lip/eyeliner pencil molding and extrusion plant with formulations, and rest you know.
-
By the looks of the formula it seems that it is an opaque formulation and the literature for Polyacrylate-33 mentions that it is incorporated for low to medium surfactant systems. Since it is a HASE polymer I am supposing that the alkali has been used to neutralize the polymer and the fatty acids both. Further I think it would keep that very low amount of soap suspended and even if something goes wrong (in case of fatty acids getting separated and settling down) the styrene/acrylates copolymer would cover it up as it is providing an opaque appearance to the formula.
Just a wild guess though. -
Guess @DandyFormulator is talking about separation in the material on storage, happens when the temperature goes down below 25C, this is mentioned in the literature supplied. But they have not mentioned anything about the salvage of the material. I would be interested too if any solution exists for such situation.
-
Thanks a ton for all the great info.
-
Great link.
-
Maybe a 2-in1 shampoo is your solution. Regular formula with a silicone (in an anionic dispersion) and a deposition agent, works pretty fine in terms of cleaning/conditioning both.
But i concur with @ Bobzchemist on that old school thing, let the shampoo do the cleaning, save the rest for conditioners and oils. -
@Bobzchemist I was thinking that but @prachi92 says that it is OK @ 20C but loosens up at 40. Now thats a bit confusing because if this micelle packing is getting disturbed by clay then why at 40 and why not at 20C. Or at higher temperature the absorption is taking place and not at 20C.
-
Prepare the same formula without this clay and check then, if so, try to reduce the quantity in the formula.
-
@IrinaTudor Absolutely brilliant. As for my fragrance supplier, I suppose it is pretty trustworthy though it’s lethargy on my part that I am not asking for composition as it is an accepted fact that Vanilla deceives.
But you have given so many points that if not prevention, guess it can be delayed or minimized.
-
At higher temperatures the particles possess higher speed and if they become faster it will lead to less viscosity and that’s why it will flow easily.
-
Yes I was thinking about PEG-12 Dimethicone but on slip parameter I thought these evaporating ones might work.
-
Bobzchemist is correct, down south in India there is no day without oil in hair (not much but maybe around 99% population), and what more, its kinda unisex. And you don’t see any breakouts and all that. I am guessing its more dependent on skin type and sensitivity.
-
@Belassi well I suppose then he should use a very little quantity of cyclomethicone or C5 (costlier) as he doesn’t mind a little haziness. I think this should improve the feel.
-
@Belassi How about your little pseudo cationic here, do you think it may work out in favor for a better feel????
-
@Ruben nowhere have you mentioned if the gel is transparent or opaque or translucent??????? It will help in narrowing down the choices.
