Diy ejuice problem

Hey guys i made a 30ml bottle 2 days ago the company i used used was from chefs flavours (UK). At first the <a href="”>juice tasted great after a 24hr steep but the following day the <a href="”>juice tastes like perfume. The percentage of flavours are 6% rainbow candy %4 lemon. 2% raspberry and 2% bubblegum. ( Sounds bad but actually tasted really good and fruity) . This is not the first time it has happened just wondering if anyone has any tips or has had this happen to them. Thanks.
