@nmalti You need a good viscosity to suspend your pearlizer, else, it’ll end up in the bottom. Alternatively, you could consider adding some suspending agent (like a carbomer).

Or xanthan gum

[Abdullah]

Make a conditioner from this 6% btms. Use it after washing the hair and thank us later.

[Abdullah]

Yes writing your formula will help.

Also can you share a photo that how it has separated? 

And what is the pH and viscosity?

[Abdullah]

Are those dots mold?

@Abdullah more cleaning and less drying (I guess butyl glycol can do both) 

Glycerin does nether of this. 

[Abdullah]

If you want to increase ph above 4.5, i would suggest add another anti fungal too or change preservative again. 

[Abdullah]

Some where someone said that the phytic acid she purchased was already contaminated. So sodium phytate is better option, costs less in transportation because it is 100% active and do the same thing.

Fekher said:

@Abdullah actually when the formulation contains pq10 without glycerin it was drying however adding glycerin decrease a lot that effect. 

It is interesting. 

I think with or without glycerin, only pq10 will sty on hair. Glycerin and all water soluble things will be rinsed by water.

Why @Abdullah? 

What quality you want to improve?

Fekher said:

Update using : water, CAPB, cocoglucoside, CDEA, PQ 10 I could reach acceptable viscosity but still lower then ordinary shampoo. Just for drying purpose I added 5 % (glycerin/MPG) then it gives better conditioning effect for hair and no drying effect however the bad surprise in such level foam decrease a lot.

So i’am thinking to make tests with different level of (glycerin/MPG) to decrease drying effect and preserve acceptable foam
 Any interpretations, comments, suggestions ? 

@ketchito @Paprik @Abdullah @Perry @ngarayeva001 

I don’t think glycerin will remove the type of drying that CAPB and APG is causing. 
Maybe that effect is from pq10

[Abdullah]

Not recommended

[Abdullah]

DMDM hydantoin or CMI MI+ sodium benzoate. 

[Abdullah]

Sodium benzoate is not enough as preservative

[Abdullah]

Polyglyceryl 4 laurate or polyglyceryl 10 oleate.

Phenoxyethanol is volatile and some of will evaporate in high temperature, if added too early at product specially in large batches. 

Where did you read this?

I don’t remember that. 

Also, adding phenoxyethanol before emulsion is made can make the emulsion less stable. 

I am currently using phenoxyethanol in leave on emulsion and other products.

ProfessorHerb said:

Thank you all so much, I don’t know how to reply to everyone but I’ll try to remember using PE9010 during the hot water phase.

Phenoxyethanol solubility in water is more than 2%. So 1% can dissolve in water easily at any stage. 
I would prefer adding it at cool down phase because it is volatile and some of will evaporate in high temperature, if added too early at product specially in large batches.

Microformulation said:

It comes in the form of Hydrogenated Vegetable Oil from the supplier. They are not converting it to a saponified soap.

The product brings a “soft” feel, emolliency, and lubricity to the syndet bar.

We used this in a reformulation of a major brand syndet as it was in the legacy formulation.

Thanks 

Does it matter what Hydrogenated Vegetable Oil we use or anyone will have the same effect?

Is soft feel & lubricity the only effect of Hydrogenated Vegetable Oil or it has any effect on foam, viscosity and detergency too?

[Abdullah]

Syl said:

It does not make sense, maybe it is soap ( hydrogenated fat with NAOH),  usually a syndet bar contains around 15% soap like a Dove bar.

In ingredients list it doesn’t have NAOH. 

pH is also 5-6.5

Doea 15% soap at pH ≤7 make any sense?

Corn strach @Abdullah

Thanks

[Abdullah]

Any examples? 
Like what powder? 

[Abdullah]

They are for shampoo. 

[Abdullah]

Isn’t there any better option for reducing cost?

[Abdullah]

Use cold processable pearl.

[Abdullah]

Yes

[Abdullah]

Yes
