If your batch is not so big, you can make another batch without fragrance and mix them.
Although i advise to always use 0.2% xanthan gun for viscosity and stability
-
How much fragrance and that preservative is in your formula and what is the pH? That preservative and fragrance both reduce viscosity.
I use 0.005% fragrance in my lotions and it smell very well. You don’t need to add high amount of fragrance in a leave on emulsion.
For this batch you can add 0.2% xanthan gun in 1 or 2% glycerin and mix it with high shear mixer. Also add a preservative for fungi too.

I am not using NACL to increase viscosity In these samples to see separation faster. With higher viscosity precipitation takes afew days.
-
I did use the search bar and did everything advised there. Didn’t solve the problem.
Actually the precipitation was in shampoo with SLES: CAPB 14:2 active surfactant pH 5.
I did try different methods. Non of them worked.
1. Adding cationic guar to 25% water, add citric acid, viscosity and clarity increased, mixed for 20 minutes, added CAPB, EDTA, SLES.
2. Added SLES CAPB EDTA citric acid to water, pH 5, mixed cationic guar with 1% fragrance or 1% glycerin, then added it at the end and high shear mixing. Next day it has precipitated.
It doesn’t have fish eye or anything
????

Could it that 20 minutes mixing is not enough for gum hydration and need more time?
-
-
My 10% SLS power needs 16% of a 50% citric acid solution to reduce the pH to 5.5. how much citric acid did you use?
-
Is it water thin?
-
Add some EDTA
-
0.05% EDTA would increase the viscosity a bit.
Use this preservative at 1% of total formula. Not 1% of water phase.
I would also recommend CMI or dmdm hydantoin
-
pH 7 is good too.
It is active surfactant.
You will use it once a month, not everyday and it is clarifying shampoo, it has to be a bit Strong.
-
I would increase total anionic surfactants
Like
5% AOS
3% sci
6% glutamate
2% amphoteric
pH ~6
pH 8 is not good
-
Just use some SLS, SLES or AOS because you are using it less often or increase sci and glutamate and decrease amphoterics in your current formula

@Perry44 hi
I receive this message to slow down???? when i comment in a discussion i have created recently. What can be the cause?
-
No, i was only mixing for 5 minutes before adding acid. What will 20 minutes mixing at this stage do?
Also i was using high shear only that the end after adding all surfactants.
Do you suggest i use high shear only after adding acid be before it too?
-
@DavidW where can i find this information?
-
By all the water you mean at least how much water?
My SLES is 23.3% active so i use 60% of it, 6.6% CAPB, 7% NACL 20% and only ~24% water is free at first for cationic guar
-
I will try adding EDTA first and see.
I have made different batches with different pH and all precipitated.
1. Reduce the pH to with 0.05% lactic acid 85 solution, that was final pH too
2. Reduces pH to 3.8 with 0.6% citric acid 50%, and at the end adjusted to pH 5 with 0.4% caustic soda 20%.
3. Reduces pH to 3.8 with 0.6% citric acid 50%, and at the end adjusted to pH 5 with 0.3% SLS power dissolved in 3% water.

You forgot to mention @Pharma
-
Surprisingly ???? i use jojoba oil to reduce my skin oiliness. Specially on nose and it reduces oil production very well.
-
Your surfactants also have water
-
Same thing has happened with dimethiconol TEA DDBSA emulsion instead of amodimethicone emulsion.
-
Same formula without amodimethicone and EGDS is stable with this amount of NACL.
-
Of course you can add it. Your formula problem might be something else.

Hi mike
I just shared my experience because i haven’t seen or used any soap in our market that is not drying. Maybe we don’t have good soaps here ☺️
-
No it doesn’t have Cetrimonium chloride. It is clear as it is micro emulsion. The one with Cetrimonium chloride is opaque and it was creaming to the top. This one is going to the bottom.
