Formula
drops = carrier mL × dilution% × drops per mL= 0.6
Note
This is a simplified model: it applies the mixing ratio, dilution, application rate, growth rate or price you enter to plain arithmetic. Mixing figures use the ratio on your own product's label, because developer, powder and colour ratios differ from brand to brand. Dilutions use C1 x V1 = C2 x V2 and the standard conversion of 20 drops per millilitre; real droppers vary with the oil's viscosity and the dropper itself. Sunscreen amounts use the Du Bois body surface area formula with the application rate you enter, and the SPF figure uses the textbook approximation protection time = SPF x unprotected burn time, which is a simplification: sweat, water, towelling, UV index, altitude, reflection and your own skin all shorten it in practice. Hair, nail and hair-removal timings assume a constant linear growth rate, which varies by person, body area, age, season and health. Costs ignore taxes, sales and waste. Always patch test a new product on a small area first and follow the product label and any professional instructions. This is not dermatological, cosmetic or medical advice; see a dermatologist or a qualified professional for anything affecting your skin, scalp or health.

How does the calculator convert a target percentage into a number of drops?+
It uses the standard approximation that one milliliter of essential oil equals about 20 drops, so drops needed = target dilution percentage x total carrier volume (mL) x 20; you enter your desired percentage and total blend volume, and it returns the drop count.
What dilution percentage is generally recommended for topical use?+
A commonly cited general guideline is 1-2% for everyday adult body use (roughly 6-12 drops per 30 mL of carrier oil), with lower percentages such as 0.5-1% recommended for facial use or sensitive skin, and children typically requiring even lower concentrations.
Why does drop size vary between different essential oils?+
Viscosity and the dropper or orifice reducer design both affect actual drop volume, so the 20-drops-per-mL approximation is a general average rather than an exact figure for every oil; thicker oils like patchouli or vetiver may produce noticeably larger, and therefore fewer, drops per milliliter.
Does using more drops than calculated improve the blend's effectiveness?+
No, exceeding the recommended dilution increases the risk of skin irritation or sensitization without a proportional benefit, since essential oils are potent concentrates; sticking to established dilution ranges is a safety guideline, not just a cost-saving one.
How do I adjust the calculation for a blend of multiple essential oils?+
The total combined percentage of all oils together should stay within the target dilution range, so if you are using three oils in a 2% blend, their drop counts should sum to the total drops that a single-oil 2% dilution would require, distributed among the oils in whatever ratio you choose.
