Does this need a preservative?
I am currently working on a few gym bag sprays/deodorizing room sprays and am unsure if I need a preservative.
Water - qs
Alcohol - 40% (Another type would have 10%)
Botanical extract blend - 0.01
Fragrance - qs
Does alcohol negate the need for a preservative? At what concentration of alcohol can I skip the preservative? Please let me know what you think!
