yes i used heat. Adjusting the PH is necessary to use it in my shampoo formulation . The initial PH was around 10.

Batch: 500 kg

Hi Guys,

Thank you all for your help. The oil content is too high, i believe now. Evchem suggestion to forgo sodium benzoate is a good idea.

I have an ultra mixer and a stirrer as equipments.

I will do some changes based on your input and get back with some feedback

If you are willing to use 1.5%!!! of TEA, then why wouldn’t you add it to the watephase instead of cool down and add 3% of stearic acid to your oil phase? I don’t like TEA-stearate personally but that would be a cheap additional emulsifier that will improve stability. The pH should still be high enough to neutralise carbomer. If you are using TEA for neutralising carbomer it’s too much.

I dont have stearic acid at hand. I have either Ceteareth-20 or polysorbate 80

sorry forgot to mention temperature. Its 70° each phase then B in A cool down to bellow 40 and add phenoxyethanol

I have too many questions but hopefully it will help you find any other issues

In what way is it not stable? Does it form properly and then fail overnight at room temperature, or after some time in an oven? Does it just not come together? 

Which carbomer are you using?  To me 1% is the upper limit, is this much necessary because you have a decent amount of salt (sodium benzoate)?

Most importantly, how are you mixing- can you give a  breakdown of what phases and what order you are adding things in, what temperature you are heating each phase to, etc?

Hi Evchem,

it form properly and then fail overnight at room temperature

Carbomer is 940 type.  i have tested it and working fine

Here are the phases

A. water	65,7
A. Carbomer	1
A. EDTA	0,1
C.Phenoxyethanol	0,7
A. Sodium Benzoate	0,5
A.Propylene glycol	2
A.Glycerin	3
B.Ceteareth-12	1,5
B.Paraffinum liquidum	5
B.Cetyl alcohol	6
B.Vegetable oil	12
B.D-Panthenol	1
C.TEA	1,5

It not about how many emulsifiers but more about which ones. You usually want different types of emulsifiers. Can you source Arlacel 165? It’s quite bulletproof. You can also mix Ceteareth-20 with Glyceryl Stearate SE.

There is also nothing wrong with adding carbomer as it improves stability.

I don’t have those emulsifiers. It will take me some time to source them but definitely will see to it

Thank you

Hi Pharma,

Thanks for your help. 6% cetyl Alcohol is to give it consistency and thickening.

I have made the following changes but still same results.

1- Added 1.5% Ceteareth-20 as co emulsifier

2- Tried without carbomer and 2 emulsifiers Ceteareth-20,12
