A cream with aluminium chloride: Aluminium chloride 20g glyceryl monostearate 20g spermaceti 2.5 g liquid paraffin wax 2.5 g aqua Conservans AD 100g

This composition resembles this of an O/W cr è me but without active O/W emulsifier. Nalauryl sulfate is not usable due to an incompatibility with all ions. Although an interaction with PEG emulsifiers is also not excluded, I would still try to use Tween 80. A quantity of 5g should suffice.
