Need advice for my formulation
this is my shampoo formulation. Sls/sles/sulphate free anti dandruff shampoo.
Antibacterial agent: 0.5 %Glycerin : 2 %EDTA : 0.5 %Lauryl Glucoside : 10%Decyl Glucoside : 6 %Coco Glucoside & Gliceryl Oleate : 2 %Sodium Benzoate : 0.1 %Sodium CMC : 1 %Lavender essential oil : 1 %Citric Acid : As neededWater : Qs - 100.IS THERE ANYTHING I SHOULD ADD OR REMOVE TO MAKE THIS FORMULATION BETTER. Please guide me. Thank you for your time and consideration.

This there anything i should do? Or this formulation is already good enough.
-
Should i add Cocamidopropyl betaine 10% ?
-
2% btaineadd selicone or poly
-
1% of EO is too high. Keep in mind fragrances reduce viscosity.
0.5% of EDTA? What type are you using? It looks high.
Glucosides make a terrible shampoo. They turn hair into a rat nest, especially withouht cationic compounds.
What is “Antibacterial agent”? Is it part of the preservation system?
And what makes this product anti dandruff? -
Sorry it was suppose to be 0.05 % of EDTA. Will reduce the EO to 0.5 % then. What other main surfactant that is sls free or sulphate free that i can use? That also has lower side effect. Should i add any solubiliser?
-
What do you mean by “side effect”?

What poly or selicone?

I mean low harm. What should i add to make this formulation better?

None of cosmetic ingredients cause harm when used as recommended.
Sulfates do not cause any “harm”. You might not like how hair feel after a generic SLS/SLES shampoo, but it’s a matter of taste not the indication that they cause harm. Also, that glucosides combination you use provides much worse sensorials than the cheapest sulfate based shampoo.I think smok meant polyquaterniums. There are many of them, 7 and 10 are commonly used in shampoos. Regarding silicones, its a bit questionable, because they supress them foam. You can add them but not much. I personally like watersoluble ones.

Will it be better. Whats your opinion. Thank you for helping

Chemophobia aside:
Sodium lauroyl sarcosinate as a main surfactant+CABP as a secondary. Add polyquaternium 7 for conditioning. Crothix liqud as a thickener.
No glucosides.

does this sound better?

Owh okay i just saw this comment.
-
The percentage of sodium lauroyl sarcosinate 10% and CABP 10% will be okay?
-
Active matter of Sarcosinate is something around 30, CAPB is around 35. 10% of each leaves you with 6.5%
Shampoo should have 15% of active matter, so you need to recalculate. -

1. What’s the antibacterial agent? Does that work as a preservative too?
2. EDTA better at 0.1%.
3. Too much glucosides will make it sticky.
4. Na-benzoate too little at 0.1%. Better at 0.5%+acidic pH, but even that’s no substitute for microbial tests.
5. I don’t think Na-CMC will thicken glucosides much, but only experimentation can tell.
6. Citric acid as needed? What’s the target pH? -

Dandruff is caused by either immune system issues or fungus infection, not bacteria. You don’t have a proper preservative system in your formula.

What preservatives should i subtitute with then?
antidandruff agent : 1%
glycerin : 2%
edta : 0.1 %
sodium lauryl sarcosinate : 20%
CABP : 10 %
polyquaternium 7 : 1%
crothix liquid : 1%
sodium benzoate : 0.5 %
essential oil : 0.5 %
citric acid : qs
water : qs -
Sorry
sodium lauryl sarcosinate: 10%
CABP : 20% -
You should understand the science behind calculating surfactants active matter.

Belassi said:940 is useless with anionic surfactants.
which grade of carbopol is better, ultrez-20/21 is not available in our country.
we have polygel-940/941/934.
Does it have any other name (ultrez-21)?
can anyone answer?
