Can salicylic acid be processed 5% together with Eumovate cream?
Answer
Eumovate Cream: contains glycerol monostearate, cetostearyl alcohol, self emulsifying glycerol monostearate (Arlacel 165), synthetic white wax (Beeswax substitute 6621), Dimeticon 20, glycerol, chlorine cresol, sodium citrate, citric acid monohydrate, purified water.
Arlacel™ 165 is described as: Versatile nonionic O/W emulsifier ( Glyceryl Stearate (and) PEG 100 Stearate) mainly used in non-polar oil phases. Tolerates the addition of mildly acidic actives and salts. Recommended topical usage levels of 1-15%.
All this merged I expect an incompatibility with 5% salicylic acid. The cream may be related to hydrophilic anionic cream of the TMF or image base in which the amount of cetyl or cetostearyl alcohol may be increased.
