How the numbers are worked out
  • Percentages are by weight, as formulators write them. q.s. marks the ingredient that fills the rest to 100%, usually water.
  • An ingredient's cost per gram is what you paid divided by the pack's weight. A pack bought by volume is weighed through that ingredient's density.
  • Nothing without a price is counted as free. The cost says which ingredients it leaves out.
  • A bottle's weight comes from the formula's density, worked out from each ingredient's density with their volumes added. Fill by weight (g or oz) and no density is needed.
  • An ingredient with no density of its own counts at a typical one for its type, read from its name, as liquidMath counts it: a silicone at 0.96 g/ml, a powder at 1.489 g/ml, an oil as a typical plant oil at 0.913 g/ml, and anything else as water, at 1 g/ml. Each typical figure is the median of the library's cited densities for its type. A figure that rests on one is marked ≈: the ingredient's own density makes it exact, and weighing 100 ml of the product makes a bottle's weight exact.
  • Alcohol and water shrink when they mix, so a product with more than 10% alcohol should be measured: weigh 100 ml of it.
  • The INCI list puts ingredients above 1% in descending order of weight; those at 1% or less follow.
  • The net contents line follows 21 CFR 701.13: ounces rounded down so it never claims more than the package holds, with the metric figure.
  • Densities come from liquidMath's ingredient library. Each was quoted from a published source and checked against it; any of them can be replaced with your own. See them all in the density chart.
