Basically i made a perfume oil using 4 different oils. 20 drops of each. It came to like 2ml then i added an ounce of carrier into it. 28ml. Is that enough or does it need 4 more ounces in there?
So you have diluted your perfume by volume to about 7.0% (2 ml up to 30 ml), is that what you wanted to do, and if so, why? Is your diluted fragrance still too strong, not strong enough or just right? Only you can answer these questions.
