Question
Posted on: March 6 2013W/O cream that breaks prednisolone 300mg erythromycin 1200mg Ichtyol 1800mg Zinc oxide 10g Ava to 60g
Adding 5-10% emulsify is ineffective.
Answer
This problem belongs to the problems of Saponin Coaltar (LCD). Icthyol contains ammonium sulfonic acid salts, which are O/W active. I can make two proposals, which should be tried once.
- Add to the water phase 100 à 200 mg magnesium sulfate;
- Add 5 à 10g starch and rub the Ichtyol with 5 à 10g starch alvortens to mix with the CR è me. This mixture can be added to the mixture of the other powders. And then mixed with AVA.
