secondary anionic
Hi Guys a question about hair and body washes in general. I use SLES as the main surfactant and as a secondary anionic, which one would you use? For example, I want to have 16% total active surfactants, of which 12% are anionic, 9% Sles and another 3% other secondary anionic. Would you wear it?

SLS or sulfosuccinate but it depends on for what purpose are you using that second anionic surfactant.
-
To not be so aggressive. For example, I would add sodium cocoyl glutamate or sodium lauroyl sarcosinate as a secondary anionic surfactant.

I usually use sodium lauroyl sarcosinate. I love glutamates, but the ones I tried, killed my viscosity (although, if you don’t mind some extra money to bring viscosity back, they are fine). Now, to make your system milder, you better add something like CAPB or an amine oxide.

Does glutamates reduce the overall viscosity or shifts the salt curve to right?
How does viscosity decreasing compare to sulfosuccinate? Is it equal, less or more?
How does foam and cleaning power of glutamate and sarcosinate compare to sulfosuccinate as a secondary anionic surfactant?

Hi. Me in my own typical recipe Shower gels Is
Water
EDTA 0.2%
Sles 33.3 %
Sodium lauroyl sarcosinate 10% cocamidopropyl betaine 6.6%
Disodium cocoamphodiacetate 5%
Olive Oil PEG-7 Esters 1%
Fragrance 0.5%
phenoxyethanol and ethylhexylglycerin 1% pH 5.5

With this recipe and with only 0.5% salt, the viscosity is very good when, instead of sodium lauroyl sarcosinate, I put sodium cocoyl glutamate there, but I did not have a good result in the viscosity with salt. I have in my possession the PEG-200 Hydrogenated Glyceryl Palmate (and) PEG-7 Glyceryl Cocoate there I see some good results and the best results but with ph 6.5 I have the Carbopol® Aqua SF-1 polymer
