My be it is because of your preservative system. 
This preservative doesn’t look enough for me

[Abdullah]

What is the pH of your Shampoo? 
These ingredients at these percentages are not drying

[Abdullah]

Thank you all 
Very informative

[Abdullah]

@chemistry8303 hello 
I currently use pq10 too but want to use Amodimethicone too. I want to know if it is a good idea to use it alone or with PQ10.

Some say pq10 helps silicone deposition. Some say it compets with Amodimethicone for negative charge. I am confused

[Abdullah]

@Andraous is 2-amino-2-methyl-1-propanol just for adjusting pH or it has other function too?

Which carbomer do you prefer? 

[Abdullah]

@Andraous thanks 
I want to add sodium lactate and sodium salicylate in this formula. 
Would carbomer be stable in it? 

[Abdullah]

@chemicallydivinelab thanks 
I did make a sample with cationic guar too. It was not stable.

Bill_Toge said:

the fundamental problem is that you’ve got nothing in the water phase to physically prevent the oil phase from coalescing and separating; what you need is something that will make the product effectively non-fluid at rest (so the emulsion droplets can’t physically move)

there are several possible ways this can be done - how viscous do you want your finished product to be?

Is it the viscosity of thickner in water phase that prevent the oil phase from coalescing and separating, or the yield value?

@Cst4Ms4Tmps4 

I Will answer all your questions that has confused you about me. 

1. A lot of things we know may not be correct. Only by asking and confirmation from someone who knows more than us we can confirm our information is correct.

2. Some questions are not answered or answered but I can’t understand it correctly or i can not do what they have said to do so i try to ask it again and differently.

3. When i do add an ingredient but can’t feel any difference i ask the experts here to make sure if it really have any effect or i am just wasting it hoping it will have an effect. For example evey one says CAPB increase the foam and mildness of SLES but i can’t feel the extra foam or mildness so i ask here to make sure it really has an effect although I can’t feel it. Or SAPDMA i added it in Shampoo at different quantities but couldn’t see any difference or benefit in foam or conditioning so i asked here to make sure if it really has any benefit or the supplier claim are false.

3. I try what ever i ask here. Some before and some after asking. 

Some questions are to know what should i do. Some questions are to confirm what i am doing is correct and not dangerous. For example about making sodium salicylate from salicylic acid. I did make lotion with %1 salicylic acid as mark said. I then did add sodium hydroxide to salicylic acid to make sodium salicylate. About 10g salicylic acid, 3g sodium hydroxide and 10g water. The salicylic acid was completely solubilized in water. I make lotion with it at %2 and the felling was better and less stinging than %1 salicylic acid. I then asked you to make sure what i did was correct and to make sure if neutralization of 1g salicylic acid gives 1g sodium salicylate. But you didn’t say anything about that. So i may need to ask a question about that to confirm what is in my mind is correct. 

And by the way my English is not very good, most of words are outo corrected by mobile keyboard here. So that my also have caused to don’t get the correct idea from what someone has said and i asked it again ????

Hope your misunderstandings about me is solved ????

[Abdullah]

@MarkBroussard thanks a lot

[Abdullah]

@Cst4Ms4Tmps4 hahaha. 
I said that because it is easier to teach something to an intelligent guy ????.
If you teach me one good thing then you are my teacher. I have learned many things from you so i respect you as my teacher. 

[Abdullah]

@Cst4Ms4Tmps4 
I did a post about non-ionic stabilizer and thickner for water phase but no one has said anything. Do you have any suggestions? 

[Abdullah]

@Cst4Ms4Tmps4 hahaha 

I was the most intelligent student in school and university. I am a Bachelor in Business Administration. I had allergy with Shampoo and i didn’t know why. I was washing my hair with a type of clay people used locally. Then after some searching on internet i thought it is sulfate surfactants that i am allergic to. I used APGs, the allergy was gone but it was not good. After valuable advises from Perry and other wise people here i made Shampoo with SLES and it was so good (better than all other Shampoos in our market) that our relatives also started using my Shampoo. Then i thought about selling it and starting a business of it. 

Now i am looking to make other skincare products too. Currently working on lotion. 

[Abdullah]

@Cst4Ms4Tmps4 thanks. Very helpful.

If i want to neutralize salicylic acid with sodium hydroxide to make sodium salicylate, should i just add and mix sodium hydroxide%30 to salicylic acid until the pH is around 6.5 or it has a specific way? 

Will neutralization of 10g salicylic acid give 10g sodium salicylate or a different quantity? 

[Abdullah]

Water phase stabilizer not oil phase

[Abdullah]

@ngarayeva001 it is water phase stabilizer. 
My mistake. 

[Abdullah]

@Cst4Ms4Tmps4 thanks 

I am using olive oil, petrolatum and non-ionic surfactant Polyglyceryl-4 Laurate. I don’t have those non-ionic surfactants you said available. Is it enough?

How to make Salicylic Acid crystals extremely small? By homogenizer or there is another way? 

Can i neutralize salicylic acid with sodium hydroxide to make sodium salicylate? 

Does sodium salicylate have the same anti acne and exfoliating effects as salicylic acid? If yes can i use sodium salicylate instead of salicylic acid for these purposes?

[Abdullah]

@MarkBroussard thanks 

I did add %1 salicylic acid to oil phase and added oil phase to water. Then adjusted the pH with sodium hydroxide%30. It is stable until now. 

Questions:
1. Can i adjust the pH of salicylic acid in oil phase or befor adding it to oil phase before making the emulsion? 

2. In how many days usually crystalization of salicylic happes as my lotion is stable until now?

3. If crystalization happens, does it destabilize the emulsion?

[Abdullah]

@ketchito what is the difference between polymeric and non polymeric emulsifier? 
Can you suggest some polymeric emulsifiers? 

[Abdullah]

@Bill_Toge 
I use Ethyl Lauroyl Arginate HCl which is cationic and gellan gum is anionic. They would not be compatible as Ethyl Lauroyl Arginate HCl is not compatible with xanthan gum too which is anionic.
Is there any non-ionic or cationic oil stabilizer option?

[Abdullah]

@ngarayeva001 what does salt and mg stearate do that it is a must? 

[Abdullah]

@Bill_Toge i think that was the problem. I made another samples with %0.1 and %0.2 xanthan gum after i saw your comment. The one with %0.2 xanthan gum is stable yet.

As xanthan gum is anionic, here is another problem. I want to add Ethyl Lauroyl Arginate HCl which is cationic surfactant and incompatible with anionic xanthan gum. So what non-ionic stabilizer should i use? 
Both natural and synthetic options. Good skin feel is preferred.

I want to make two versions. One low viscosity less than 3000 cps and one lotion. More than 20000 cps. 

[Abdullah]

@ketchito i am locking for a cold processable emulsifier.

[Abdullah]

@singhc10 it is low viscosity lotion pump

[Abdullah]

@ketchito the Hlb of oil mix is 6.97 
If i increase the amount of high HLB emulsifier it would be more than 6.97. 
Is that ok?
