|The following chart contains the most useful solvents for each active. If you click on the active name, it will redirect you to the optimal pH range for formulating as well as % usage.|
*n.b. Use the least amount of solvent possible to get the active into solution. Account for its weight as part of the oil or water phase respectively and make the appropriate adjustments to your formula/ recipe in the batch size calculator.
1 N NaOH = 0.39 grams NaOH dissolved in 10 grams distilled water. Use the least amount necessary.
1 M Citric Acid = 1.92 grams C3H4OH(COOH)3 dissolved in 10 grams distilled water
H3C6H8O6 + NaOH --> Na3(C6H8O6)+ 3H2O
Citric acid + Sodium Hydroxide----> Sodium citrate salt + water
