So in the patents of K&B solution, the solutions of 5% and 2% are:
Kraemer & Bohn’s 5% RU58841 solution (KB5)
- 27% Demineralized water
- 63% Ethanol (96%)
- 2.5% BASF Cremophor RH 410
- 2.5% BASF Luviquat FC 550
- 5% RU58841
- 27% Demineralized water
- 63% Ethanol (96%)
- 2.5% BASF Cremophor RH 410
- 2.5% BASF Luviquat FC 550
- 5% RU58841
Kraemer & Bohn’s 2% RU58841 solution (KB2)
- 54% Demineralized water
- 40% Ethanol (96%)
- 2% BASF Cremophor RH 410
- 2% BASF Luviquat FC 550
- 2% RU58841
- 54% Demineralized water
- 40% Ethanol (96%)
- 2% BASF Cremophor RH 410
- 2% BASF Luviquat FC 550
- 2% RU58841
The ratios change mainly in these two.
60ml 5% solution contain 27% water (something like 16.20 ml) and 63% ethanol (something like 37.80 ml)
You have to start with yours 60ml, let's assume you'll make the double of this - 120 ml - wich will get you a little more than 2% of RU concentration, and we can try to base our math in the Kraemer & Bohn’s 2% RU58841 solution.
120ml 2% solution contain 54% water (something like 64.80 ml) and 40% ethanol (something like 48.00 ml)
Based on the diferential of water between 5% (60ml) and 2% (120ml) (16.20ml / 64.80ml) I guess you can try to add something like 48ml of distilled water.
Based on the diferential of ethanol between 5% (60ml) and 2% (120ml) (37.80ml / 48.00ml) I guess you can try to add something like 12ml of ethanol (96%).
I don't know if this will work...I would appreciate also someone's thoughts on this...
Resuming: Add 48ml of distilled water and 12ml ethanol (96%), you will get 120ml with a much more diluted solution.
