Question
Posted on: March 6 2013Is there a magijet alternative to Andina, which remains stable after preparation?
Answer
I would suggest following CR è me once to test out: Hydrogen peroxide 30% 10g; Tween 80 3.5 G; Phenacetine 20mg; Na2EDTA 500mg; Phosphoszuur 0.3 g; Glycerin 30g; Cetostearyl alcohol 10g; Reage. Paraffin wax 5g; Vaseline 15g and water up to 100g.
of course make the CR è me beforehand and after completely cooling add hydrogen peroxide. Packing in lacquered Al tube. Store in the refrigerator. Shelf Life 1 month (to start). If necessary, the concentration of hydrogen peroxide can be increased.
the stability can be followed very easily by a titration according to the Pharmacopoeia: dilute 10g with water up to 100ml. Add to 10ml 20ml diluted sulphuric acid and tritreer with KMn04 until a pink color appears; 1ml of the tritreerliquid corresponds to the With 1.7 mg H2O2
using a few provisions: 14 days, 30 days, 60 days etc, the expiry date can be determined.
Should this CR è not satisfy me then it may be considered to look for a W/O formulation.
