Question
Posted on: March 6 2013Problems with following preparation: Aluminium chloride 20 g glyceryl monostearate 20 g Spermaceti 2.5 g liquid paraffin oil 2.5 g Aqua conservans Ad 100 g
After mixing the water and oil phase (70 ° C), a watery mixture was obtained, certainly not available.
Answer
Do not use self-emulsifying GMS (from the PBV) because by reaction with all ions the soap strikes down in the form of Al-stearate,-oleate. In the process Cetomacrogol (non-Ionogen) and cetostearyl alcohol (for the formation of self-emulsifying wax).
use alhydroxychloride instead of alchloride; less irritating
Preparation method:
- measuring cup tare
- oil phase: 16g Cutina MD, 4g cetomacrogol, 2.5 g spermaceti and 2.5 g liquid paraffin together warm up to 70 ° C
- Water phase: Dissolve Aluminium chloride in Aqua Conservans and Warming up to 70 ° C
- water phase at oil phase joints and stirring until cold
- correct for evaporating HVH water
- homogenizing mbv bamixmixer
