@B@Bhartisaroha Indeed, DMDM hydantoin is a better choice, since you have too many ingredients that increase risk of contamination, and Geogard ECT alone wouldn’t be enough. Keep in mind that you also need an antifungal for broad spectrum preservation (you can use Glydant Plus or similar). Also, you have both Glycol stearate and Glycol disterate at very high levels with nothing to tabilize them. Do you want your product to be opaque/pearlized? If not, you can remove them, since they could be impairing stability of your product.

Yes I want my product to be opaque..at what percentage should I use EGMS?
Or should I use EGDS alone?

The biggest problem is this, you are making a shampoo. The purpose of a shampoo is to remove things from the hair. Anything in the formula that is not helping to remove things from the hair is leading to a worse performing shampoo.  So…

Step 1 - Remove everything in your formula that isn’t necessary for CLEANING the hair or stabilizing the formula.  Also, use Deionized water instead of hydrosols.  This would include:

Rosemary hydrosol
Frankincense hydrosol

Glycerin
Sodium PCA
Oil
Hydrolyzed milk protein
Hydrolyzed soya protein
Hydrolyzed rice protein
Glycol stearate
Glycol distearate
PQ-10

Step 2 - Adjust the pH of the formula to the proper level which should be pH=5 (or less)

Geogard ECT is made up of organic acids which do not work as preservatives unless the formula has a pH of around 5.0.  At pH 6.0 your product is not preserved.

Step 3 - Test the formula

If this is stable, then you can add small amounts of the non-functional, claims ingredients like protein & hydrosols.  And you can add in PQ-10 for a little conditioning & Glycol stearate for a pearlizing effect.

You have to decide what you are making.  Do you want to make a product that works, or do you want to have a list of natural ingredients that are blended together but don’t actually clean the hair?

What if I use DMDMH as a preservative.. what should be the pH of shampoo then
Also…this shampoo have ASM Of 19… should I reduced it?
