Unable to thicken up
Can anyone help me with my bath gel formulation please? I highly suspect that the surfactants are the culprit to low viscosity issue. Should I change the surfactants combination? I’m trying to use EWG green rated ingredients for my bath gel. Thank you.
Water 72.6%
Disodium EDTA 0.05%
Glycerin 3%
PEG-150 Distearate 0.5%
SCI 3%
Sodium C14-16 Olefin Sulfonate 5%
Lauryl Hydroxysultaine 7%
Sodium Lauroamphoacetate 3.5%
Olive Oil PEG-7 Esters 0.5%
Lavender Oil 0.5%
Decyl Glucoside 3%
Hydroxyacetophenone 0.5%
1,2-Hexanediol 0.5%
Caprylyl Glycol 0.15%
Ethyhexylglycerin 0.2%

Have you tried salt?

Yes I did, but doesnt help much

Remove Glycerin and Decyl glucoside (you could replace the last one by Coco glucoside, if you want).
If the Alpha olefin sulfonate is at 40%, double the amount.
Replace Lauryl Hydroxysultaine by Cocamidopropyl Hydroxysultaine.
That should give you a thicker system, and if you require more, add a bit of salt or Cocamide DEA (or similar).
By the way, your preservative system is not robust, but @PhilGeis would be more suited to comment on that.

Will try your suggestions and see if it helps! Thank you 😁

As my friend ketchito said, that is a weak system. How did you come up with it?
Need a primary - CMIT, PE or the like

I have found adding ingredients before PEG-150 can significantly affect the resulting viscocity. I would add the PEG-150 in first.

I added PEG-150 in the beginning too but still unable to get the desired viscosity

What ketchito said+ Ethyhexylglycerin, 1,2-Hexanediol, caprylyl Glycol & Lavender EO all reduce viscosity
