Shampoo residue
in Formulating
So i make a basic shampoo that includes
Sles
sodium chloride
edta
acv
Glycerine
water
parabens as a preservative.
I always melt the methyl in the glycerine before i add water and the acv. Phase A has Sles,sodium chloride and the edta.However,the end product always has a white residue at the bottom with a few solid particles that i have to discard.
What am i doing wrong guys? Is it the propyl or the sodium?

Comments
Regarding acv, I always would use bcv instead!
"What am i doing wrong guys?"
The whole process looks wrong.
"Is it the propyl or the sodium?"
I don't know, you haven't mentioned propyl anywhere. Sodium what? Whatever sodium it is, it depends on the quantity you are adding.
I use methyl in the water phase and the propyl in the chemical phase which includes sles, sodium chloride and edta.
I'd suggest your to keep getting more knowledgeable. Parabens are solubile in hot water. If your process is cold than, Parabens will not dissolve.
Your process of production is way off the right way.
Heat water at 80C, add Parabens stir till you have a solution, drop the temperature to 70C and add sles. Keep stirring till you have a clear solution After that decrease the temperature to 40C add edta and stir til it dissolves. After that add the other ingredients at room temperature ending with sodium chloride
I will try your procedure and get back with results.
Since you are still learning, I'd suggest you to post your formula here. I'm not sure if the percentage of each ingredient is correct.
2.5% salt
1.5% cde
0.15 edta
7% glycerine
0.15 methyl
0.15 propyl
Water
If you are working with SLES 70%, I think you should increase a little the surfactant concentration, probably 10-15%
I think your formula will not foam good enough.
How about 5% glycerine? It's for ethnic hair, so I want to make it as gentle as possible.
The fragrance often decreases the viscosity. One more thing to check out is the pH. I'm pretty sure the pH is over 7, probably even over 8. If you use acidic ingredients, like citric acid or lactic acid you can adjust the pH and in the same time increase the viscosity.
Also take in consideration to decrease the quantity of your fragrance.
