Read about salt curve. Plot a curve with minimal salt and inceease in bits. It may be that any of your raw material already has salt (one supplier gave me CAPB that had some salt). Salt curve is to be plotted by you for your formulation.
I have read the discussion and found it a wonderful one !
I too have always wondered how soaps with little contact time claim to deliver benefits. Then recently I have started using shampoos that are sulphate, silicon and paraben free (advisable …
Thanks for responding @Pharma and @ozgirl.
So as long as the two are kept separate they are gonna be effective (after mixing).
I do not have the option of Isotheozolinone (viz. Kathon) as it is available only in huge quantity. Benzoate i…
thanks for responding.
There is no mention of the content other than the small (100ml) bottle as the activator and the larger portion in jerry can as the 'solution '.
Attaching images too.
My intended use is as a preservative for surfac…
Thanks a lot @EVchem.
Yes, I had done a salt curve analysis and was sticking to the amount that served best. I had to re-do it when I changed my CAPB supplier, and realised it already has salt and needed no additional salt.
As regards EDTA, with …
Yes, at pH 8-9 the conversion and dissolution happens.
So, last time I added EDTA (Disodium) in the NaOH solution first at pH8. Then proceeded to other steps.
Got disodium EDTA mistakenly and have to consume it so.
Yes, that was my concern too. I read about deriving tetrasodium EDTA from disodium EDTA by the use of alkaline medium like NaOH.
It says, use the amount disodium EDTA equal to the amount of tetra sodium EDTA needed in the formula a…
Thanks again. The L1 I mentioned above is the liquid I prepared using salt. It was much thick in the stable state than L2 the commercially available dishwash liquid.
I guess I need to increase the active ingredients' concentration.
