@ariepfadli
Thanks for sharing your experience. Really appreciate it.

@ketchito, thanks for your help. I am definitely going to try this method. Hopefully it will fix the issue. We are using Dowsil 2- 8566.

@Abdullah, sorry for the late response. Sure I can.

Hi Ketchito,

Thanks for your help. We also tried the same method. Added right after oil phase once emulsion was formed. The batch was looking quite good (Smooth cream) throughout the process. however, when we changed the pH with citric acid at the end, it reacted the same way.

@waterphase
yep i’ve used Polyfix XRC 25GP and it is incredibly easy to use. the only thing you have to keep in mind when using this product is with any compounds that have -N or -S in them as that is how Zinc Ricinoleate works. This includes your fragrance.

your ingredients list looks fine

[billichemist]

@dilfre yes thank you! however i meant its a soap free cleaning bar/paste. sorry that was my mistake!

[billichemist]

@Chemist77 
 i will try it just to see what effect it has but i cant be in the final formula because its mean to be certified organic. 

do i put it in the hot phase or can i post add/ add in the cold phase?

@johnb yeh water, preservative and some extracts and i have a littl ebitof xanthan gum in it,

@ozgirl os it says less fatty alcohols!! i am so confused

[billichemist]

@chemicalmatt 
Thank you for that! it currently already has 1.5% cetyl alcohol in it!!!

here is the emulsion system..

olivem1000-1%
Cetyl alcohol - 1.5%
Stearic Acid -0.8%
Glyceryl Monostearate -0.8%
coconut oil - 0.5%
macadamia oil - 3.5%

% of emulsifiers to oil is 28%. should i increase the cetyl alcohoL?

[billichemist]

i also have 0.2% xanthan gum in the emulsion. will that affect it?

@thebrain 
 this is what my supplier gave me as instructions

1.      
Use 2%

2.      
Add 2% to 20% water at 40C

3.      
Star stirring, it won’t dissolve until you adjust the pH

4.      
Adjust the pH to 7-7.25. You’ll notice that it dissolves and you get a
clear solution

5.      
Add to the bulk of your formulation (you don’t want to add the 2% to
your bulk because then you have to heat the whole bulk up to 40C and that’s a
massive time/energy waster)

6.      
Adjust the pH of the bulk to 4.75 – 5.25

 

IF
you have problems with the pH drifting over a long period of time, I would
suggested you add 3% sodium citrate to step 2 (in addition to the 2% Geo Ultra
and 20% water).

maybe this will help? 

[billichemist]

what is the difference in hold if you use ceteareath 20 to 30 as compared to cetearth 25?

[billichemist]

What if you preserve the water that the dry clay would be mixed in. would that be sufficient?

[billichemist]

THanks guys!! im doing a pilot batch and fill stability just to make sure!

i have trouble with bentonite gels and surfactant type formulas.

with the bentonite gels, i am using 0.2% panisic acid and 1% phenoxy and it is failing my microbial tests. i tried it in a face cream and that combination was fine but it didn;t give me the same result in the bentonite gels

with my surfactant formulas, they are crashing out the viscosity and makes it go really thin after 2 -3 weeks! it is a simple ALS body wash formula. Using just phenoxy is fine for viscosity but i was just trying to boost the  preservative system…. 

[billichemist]

oh good cause thats how i formulated it.

what about preservation problems?

[billichemist]

if a wax forms a gel at a lower temp will that mean it will be less likely to grain up because it would become a gel at a larger range of temps?

[billichemist]

@Margreat how did you go incorporating your Benzoin oil? I tried to put it into my cream but it sort of solidified and became a resin again! like little hard rocks in my  cream! 

i used a resinoid so i thught i could jsut add it in?

@georgetedder what is DPG?

[billichemist]

i have the same problem!!!

[billichemist]

@chemicalmatt what will the hectorrite clays do?

[billichemist]

@Vin  How exactly does one use a buffer to stabilize it? do we just add an equal amount of sodium citrat + citric acid buffer as ascorbic acid to the final forumlation? or pre dissolve the ascorbic acid into the buffer? sorry this is such a basic question! i feel like i should know this but i dont!

[billichemist]

@MichelleReece  unfortunately, client wants nothing to do with silicon/dimethicone/polymers

@Microformulation  yeh i know about sepigel and have used it. its amazing! but again, clients arent into ‘chemical-y’ sounding INCI names

good article though!

[billichemist]

@ozgirl mine does exactly the same! problem is, it gets so thick (before i add the acids) that the tank stirrer struggles! its an incredbily drastic change in viscosity

[billichemist]

Ah hah! of course! thank you!!!!

[billichemist]

ressurrecting this thread…. i still havent found the reason! 

[billichemist]

I use Bamboo exfoliant particles from lessonia! theyre white as snow!
