@ketchito how does NACL effect cationic guar in a Shampoo with SLES/CAPB?

Does THIS work?

Can’t open it.
Is it a file to download or link to open? 

Some times my phone doesn’t download files properly.

Regarding solubility etc. HERE‘s some nice reading.

Can’t open it.

sodium lauroyl methyl isethionate primary
CAPB secondary

You can heat the product to evaporate the water and see what percentage is total solids. 

If it is leave on hair product in my opinion everything is below 1% or Cyclopentasiloxane is 1-2% and the rest of it is below 1%.

[Abdullah]

40% sodium hydroxide is very strong. I make 10% of it and even that increases pH a lot very fast.

[Abdullah]

Whqt are the ingredients?

What was the pH before & after?

[Abdullah]

Is that actual surfactant or active surfactant percentage? 

How much salt is this come salt? 
You can add less salt.

[Abdullah]

You need sufficient surfactant and softening agent for any type of hair.

[Abdullah]

Use Glycol stearate instead of distearate.

[Abdullah]

If it goes into eye there are more irritating ingredients like preservative, chelating agent and fragrance & other ingredients in your product than pH. 

You should avoid it going to your eyes.

[Abdullah]

I don’t have experience in hair gel but all my products including emulsions are in flip top bottle. 

[Abdullah]

If you are are a startup, bottle is better for you than jar in any way.

- it is less expensive 
- it is easier to preservative the product in it

- high viscosity cream only has more thickener than low viscosity. No other difference. You can reduce the thickeners and save more money.
- easier to make lower viscosity product
- easier to fill lower viscosity product.

@PhilGeis It’s a jar. I know, I know that’s the worst thing to put my product in but at the moment in this stage of development that’s all I can do. I would love for my formula to be in a tube to reduce contamination but it’s just not feasible at the moment. That’s why I’m looking for a robust preservation system. 

@MarkBroussard ok thanks.  I will order 1,3 propanediol. Would it make sense to add Peg 40 hydrogenated castor oil to help with solubility along with 1,3 propanediol or just use the 1,3 propanediol?

Why are you not using a flip top bottle. It is cheaper and better than jar.

[Abdullah]

Is it supposed to be applied around the eyes or inside the eyes? 

If around the eyes then pH ≤4.8 is better.

I don’t know about inside the eyes. 

[Abdullah]

Yes 
Got it
Thanks

No problem @Abdullah if you need help for such category i’am here????. 

Sure i will contact you. 

Currently don’t have any plan for such product.

Hair wax is used to hold hair in whatever style you want it. Correct?

[Abdullah]

Fekher said:

@Abdullah according to your expertise what input will you suggest even more then ingredient or unlisted? 

Sorry i didn’t have experience in this category.

[Abdullah]

I don’t have explanation for it. A chemist here told me to do so, i did and got the results. I don’t remember it correctly but i think it didn’t work in anionic emulsion.

[Abdullah]

@PhilGeisis benzyl alcohol anti bacterial or anti fungal? 

[Abdullah]

Here’s the link - https://www.jidonline.org/article/0022-202X(86)90008-4/pdf
I’d not get carried - no standard deviation in this or Fig 1.

It says This page does not exist.

[Abdullah]

PhilGeis said:

Wouldn’t the Na salt be more cooperative?

Generally it is. 

Only advantage of sa is you can use small amount to reduce pH too.

[Abdullah]

@vitalys thanks 
Is this photo from a book? 

[Abdullah]

Mikrokill COS will be good at pH ≤5. At pH 7 look for PhilGeis suggestion. 

[Abdullah]

It was for viscosity and stability.
