Do I need an igredient in a natural cleaning product

[elle110]

I have developed a all natural all purpose cleaning product to go in my line but so far I have made it in very small batches and it has been used up quickly, it ROCKS but do I need a preservative or ROE to preserve or prevent rancidity?

The main ingredient of course is distilled water and other essential oils, I didin't know if EO and water have the same reaction as water and carrier oils as far as mold etc

Also, this might need to be in another area instead of B&B

TIA
