How much oil could I use with SD-3 and cetearyl-7?

When I measure pH of creams, I stick the pH electrode in the cream, even if the cream is thick, and move it gently. Is the pH measured this way reliable? Am I doing it right?
I read somewhere that in thick creams it is difficult for the ions to migrate to the electrodes and therefore the pH reading cannot be reliable. The suggested method was to dilute 10% of cream in distilled water. However, this confuses me because with addition of water, I think the pH will change and be different from the pH we want to measure (that of the cream).

So what is the right way to measure pH in thick creams? Any thought?

Thank you!

I honestly would like if anyone has answers to this. I feel the samevway
