Why PEG-12 Dimethicone has better solubility compared to PEG-150 Distearate?????

[Chemist77]

OK now PEG-12 Dimethicone to PEG-150 Distearate????
No you are not wrong, I am just trying to understand the concept here.

[Chemist77]

@nasrins so why PEG 40 Hydrogenated Castor Oil is readily soluble in water compared to PEG-150 Distearate (forget the physical state)

[Chemist77]

As Bobzchemist pointed out in one of his posts you are not getting enough yield value with this polymer or the surfactant combination is negating the yield value of your polymer. Viscosity has nothing to do with suspending ability, your yield value is definitely not enough to overcome the effect of gravitational pull on your beads. Either try a better polymer, (I love Aculyn 22) or go soft on your surfactants. Make sure if any of your surfactants has electrolyte content and how much is going into your formula. Electrolytes interfere with polymers and have a very adverse effect on yield value of certain polymers.

@nasrins how does this ethoxylation effect the hydrophobic/hydrophilic aspect??? Is ethoxylation directly proportional to ease of aqueous solubility or other factors play important part too to determine the tendency of the molecule?????????

[Chemist77]

Did you neutralize the polymer????????

[Chemist77]

I would be shocked even if it stabilizes below that, a simple example being a shampoo with a little coconut or any other oil for softening properties. Its like playing soccer game on the moon n finishing it without losing the ball

[Chemist77]

@gfeldman wonderful input.

[Chemist77]

try it and check, its all about trials and errors.

[Chemist77]

Just a very naive and stupid idea but maybe you have to be close on the densities as well for both the silicon and organic oils or else you would have two phase product on hand

[Chemist77]

HEC, Sodium CMC, xanthan dont have poly as a prefix to their trade names

[Chemist77]

guess nasrins is asking for beads????

[Chemist77]

@Bobzchemist wonderful explanation.

[Chemist77]

@Bobzchemist now thats a wow suggestion. Apologies but taking it further from here, I have formulated something similar with a little gold pearl. If I use Aculyn 22 its holding the pearl but without the presence of polymer gel network its settling down even if i am able to increase the viscosity. Do you think a gel network is must to keep these pearls sudpended??? Its a normal pearl like cloissone or timica gold pearl.
Sorry again for encroaching!!!!!

@Chemicalmatt

LOL. Knock Knock researchers, is someone listening about sugar too??????????

[Chemist77]

Since it seems to be a sulfate free formula I am confused if the electrolyte part of CAPB is really going to aid in thickening, though Zink you can try HPMC which might thicken better than Crothix. No harm in trying and letting us know as well.

Cheers

[Chemist77]

This is specifically meant for such surfactant systems and I am sure it would perform much better than xanthan.

[Chemist77]

Try Crothix liquid from Croda, a very versatile thickener designed especially for such surfactant systems.

[Chemist77]

DC 5225C from Dow Corning, can start with 3% level.

[Chemist77]

Oh my, well I suppose then you should try with your PEG 150 DS, try increasing the quantity of PEG 150 DS if at all you dont have access to any other raw material.

[Chemist77]

Akshay where are you located?????

[Chemist77]

@Martinkul Can you tell us how did you get the idea about the ingredients mentioned above, just a random mixture or you went through the literature of these materials to make your cream. First rule, make basic emulsion cream or lotion and then add your essential oils, fragrance or any other additive.
How did you add your salicylic acid and menthol crystals in this formula?
Get the emulsion right first by selecting the correct ingredients and then think of moving further. Once you have a stable cream or lotion then you add other additives either directly or after solubilizing them in right solvents.

[Chemist77]

@Akshay cetostearyl alcohol, cetyl alcohol, glyceryl stearate se, little LLP or any other light ester oil of your choice, a little of sodium benzoate and around 5-8% of cetrimonium chloride 30%, there u hv a basic working formula. You can add Polyquat 7 and other additives once u get the basic formula right.

[Chemist77]

I think he wont need too much of preservative here as cetrimonium chloride itself is a good antimicrobial but i m not sure if that 2% is active or 2% of 30% which is generally sold in the market.

[Chemist77]

hehehehehe good one
