What is your preservative? my suspect is conservation problem or perfume or both.

Hi, as the end pH is 3-4, hence, i do not add any preservative into the system..
-
Not really you don’t need preservative.
@PhilGeis what do you think?
-
No pH 3-4 is not low enough.
What is the entire formula?.

Can you make a sample without BHT? Sometimes it reacts with nitrogen compounds, giving a yellow color.

May i know which ingredient contain the nitrogen compound ?
