@Perry thanks a lot. It is dye then.

It is powder and sold locally with SLES. I don’t know if it is dye or pigment.
What is the difference?It is yellow color. I want Shampoo to have orange color

@Pharma
Would water soluble rosemary extract have the same effect as ROE if added to a cream with unrefined hempseed oil which goes rancid very quickly? -
@Pharma thanks
Is rosemary extract oil soluble?
At what percentage should we use these two?
Which type of tocopherol is better?

.It is inexpensive
. It is completely water soluble
. Usage rate is %0.1-0.6
. The mic for Aspergillus niger and Candida albicans is 200ppm or %0.02 -
@Perry that is Hydroxyethylcellulose. I asked about Hydroxypropyl Methylcellulose if it is compatible with %15 APG. I have seen 2 manufacturers one said it is not compatible one said it is compatible. So i thought i may find correct answer here.

@justaerin thanks
. It is glyceryl stearate alone not the se.
. I will replace GMS with cetearyl alcohol and see if it make any difference.
. Yes sodium phytate increase the pH and i reduced it with citric acid to 5-6 before mixing.
. I will use %10 BTMS and see what it does.
. Do we need to add water to oil when the oil phase is very small? -
@Perry is Hydroxypropyl Methylcellulose compatible with %15 APG surfactants?
-
@Gunther yes it is %75 cetearyl alcohol.
@ngarayeva001 your formula has many emulsifiers. BTMS %10 which is the highest %of use, ceteareth-25, Myristyl Myristate,Quaternium 80. They are all emulsifiers and co emulsifiers.
Can BTMS be used as emulsifier without another emulsifier?
-
Of polyquaternium 10 and 7, do both thicken the product?
Which one thickens the most?
If the same INCI PQ 10 vary significantly, is there any other specification that we should check with supplier or just buy from different suppliers and check which one works better?
-
I have used Hydroxyethylecellulose but it does not thicken the product. It doesn’t even thicken the water alone.
Does it have any specific method to thicken like cationic guar that needs the pH to be neutralized?
We purchased from India and sellers there don’t have enough information about how to work with it.

@natzam44 @Perry thanks
Yes we used SLS at %12 and it was ok but now we use nonionic APGs at %15 still it fells the cleaning power is not good enough.How much ASM for APGs or can i find a comparison of cleaning powder for different surfactants?

Thanks a lot -
Thank you all
@Agate yes that is one reason but people here assume anything that ends with sulfate the same. Any other suggestion?
What about coco glucoside instead of decyl glucoside? Does it have the same effect?@Belassi i used CAPB but no benefit, even less foam and cleaning power.
GMS, yes glyceryl mono stearate, i added it assuming it will reduce the dryness but it only reduced the foam.
Benzyl alcohol and dehydro acetic acid(geogard 221) preservative mix.
I only add glycerin to dissolve xanthan gum in it before adding it to water.@ozgirl that would be a good point.
What thickeners do you recommend?
I have tried working with guar gum, cationic guar gum and Hydroxyethylcellulose but they didn’t thicken the water alone, may be they work different than xanthan gum and i don’t know.
I have cetearyl alcohol too but haven’t tried it in shampoo.@Gunther any alternative to silicone?
A book mentioned that cationics reduce the wet combability of hair for APGs as in the photo.
Does sodium phytate have any effect to be reduced?Would adding glyceryl oleate, panthenol or protein reduce dryness?
Do these have any effect on foam? -

@Belassi, @Perry thanks.
Is the surfactant the only problem or there is anything else too?What is the problem with this surfactant? Is it harsh, iterating, not able to clean well or something else?
Will changing the quantity do any benefit?
We have 1 ton of it in stock, we purchased it thinking it is the mildest surfactant according to comparations in Internet and powerfull enough to be used as primary surfactant.

MemberFebruary 11, 2020 at 4:08 am in reply to: Preservative for nonionic surfactant shampooThank you all from your informative comments.
Can i use Piroctone Olamine as only preservative in Shampoo with %15 active surfactant decyl glucoside?
In attached photo you can see it has broad spectrum activity and MIC is %0.05 or less.
At what percentage can i use it as only preservative for Shampoo? -

MemberFebruary 11, 2020 at 3:56 am in reply to: Propanediol vs methyl Propanediol as solventGlyceryl caprylate, Ethylhexylglycerin, Piroctone Olamine, Caprylyl Glycol.
In surfactant system we have %15 active decyl glucoside and in emulsions SSL and GMS emulsifier.
I want to be able to add these in water face pre emulsion. -

I am convinced not to go for hyaluronic acid.
