use of methyl salicylate along with Oleyl amine ethoxylate
Hi all,
I’m in the process of formulating toilet bowl cleaner for my new startup.
I use
HCL
Oleyl amine ethoxylate(Acid thickener/ fatty acids)
as per the formulation need to use methyl salicylate as odorant.
but the problem is when i add methyl salicylate to the hcl + fatty acid solution
it looses the viscosity and there’s a change in the color.
Note. i’m adding < 10ml(methyl salicylate) to 5ltrs of end-product
what am i doing wrong here ? -

@sandyzden Toilet bowl cleaners is usually acid, but I’d like to know what’s the pH of your mixture before adding the Methyl salicylate? Is the final color after adding the methyl salicylate, yellow?
-
before adding methyl salicylate, i’m adding acid stable blue color which is dark blue in color, post addding MS i turns into sky blue
-
@sandyzden Perhaps MS is causing a pH shift (a secondary reaction might be occuring). What’s the pH of the product before and after adding the MS?

We can assume pH is not relevant here - with HCl as de-scaler this is REALLY LOW - like 1.5 right? What is the greater problem Sandy, viscosity loss or color-change? I’ll wager a little of that methyl salicylate is hydrolyzing to salicylic acid and complexing with your dye. As for the viscosity: no comment.
