Formula
C1 × V1 = C2 × V2= 10
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.

What do terms like eau de parfum and eau de toilette actually mean concentration-wise?+
These terms refer to the percentage of aromatic compound (perfume oil) dissolved in the alcohol/water base: parfum is roughly 20-30%, eau de parfum around 15-20%, eau de toilette around 5-15%, and eau de cologne around 2-4%, with lower concentrations generally meaning lighter scent and shorter longevity.
How does the calculator determine dilution from a target concentration?+
Given a target percentage and a total batch volume, it calculates how much aromatic oil versus how much diluent (typically perfumer's alcohol) is needed: oil volume = target percentage x total volume, with the remainder made up by the diluent.
Why does the same oil smell different at different dilution strengths?+
Different fragrance notes evaporate at different rates and become more or less perceptible depending on concentration: top notes tend to dominate more strongly at lower concentrations while base notes become more prominent as concentration increases, so a dilution is not simply a volume-scaled version of the same scent experience.
Can I convert a home-made blend's concentration into an equivalent commercial category?+
Roughly yes: if you calculate the oil-to-total-volume percentage of your blend, you can compare it against the typical ranges for eau de toilette, eau de parfum, etc., though commercial naming also depends on the specific formulation and brand convention, not concentration alone.
Why might a higher-concentration perfume not necessarily be 'stronger' smelling?+
Perceived strength depends on the specific aromatic compounds used and their individual scent thresholds, not just total concentration, so a lower-concentration blend using strong, potent ingredients can smell more intense than a higher-concentration blend of milder ones.
