Simply, to start from my information space, does pH have anything to do with the effectiveness of hair straightening in the product

If you’re looking for a final review before embarking, here is my suggestion.

Get rid of most of your ingredients. Start simple and then add ingredients as necessary.  Make this formula…

AQUA

Mono Propylene Glycol

QUATERNIUM-80 or AMODIMETHICONE (you don’t need both)

DISODIUM EDTA

DMDM HYDANTOIN

Methylparaben

Test it.  Then add ingredients to this formula as needed.

Panthenol is a claims ingredient. It does nothing noticeable if there are other ingredients like silicones present.  Salicylic acid does not protect hair from sunlight in any noticeable way. 

I do not believe Glycolic Acid will do much for straightening hair either. However, the suppliers make some claims about it so it might be worth testing a formula with and without Glycolic Acid to see if it actually does anything. 

But overall, when you are starting a formulation project use FEWER ingredients for your first formula. Don’t start with a dozen ingredients because you will have no idea what ingredients are actually having an impact. Add ingredients to solve demonstrated problems. Don’t add them because you’ve been told they will have some effect.

That’s what I hope for, thanks for the advice

I will start preparing accordingly, and I will keep you posted on the results

What is the pH?

You need an antifungal preservative too. 

DMDM HYDANTOIN
Preservative and antimicrobial

That is weak for fungi.

Do you have a better alternative?

What question do you have about the formula?

Obtaining final review and approval before
starting implementation, based on the purpose of product formulation

Have you made the formula? What were the results?

I will start preparing after the discussion
here, and I prefer that

What do you want improved?  Was the formula stable?

The main objective of the product:

-Straightening the hair easily and without
damage to the scalp and exposure to heat for a long time

-Use the product before ironing or blow-drying,
to avoid damage

-Directing the product to the customer directly
without relying on the salon, or maintaining the hair after the session at home
for a longer life

Just at a glance, I think Panthenol at .75% is useless and unneeded. 
I don’t see any benefit to including both Salicylic acid and Glyoxylic acid. One acid is fine. 

PANTHENOL

Do I understand from your observation to
increase the percentage or dispense with it?

 SALICYLIC ACID

Its purpose is to protect hair from sunlight

 Glyoxylic acid

Its purpose is to re-straighten the hair

But really…what specifically are you asking about?

Check the final formula before implementation
to achieve the desired goals of the product

Hello, my question includes getting a hair straightening protein spray, the goal is to straighten the hair by 75% for curly hair, moisturize the hair and repair it.
