How do you disperse zinc oxide in lotion?
Dispersing in Water: Dispersing in water can be considered for untreated zinc oxide powders. Premixing with a humectant or water-soluble emollient can improve dispersion. Following this step, we suggest mixing in water phase until uniform and conducting proper homogenization of the emulsion.
How do you dissolve zinc oxide?
It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid: ZnO + 2 HCl → ZnCl2 + H2O. Solid zinc oxide will also dissolve in alkalis to give soluble zincates: ZnO + 2 NaOH + H2O → Na2[Zn(OH)4].
How do I make ointment?
Procedure for Preparation: Melt the stearyl alcohol and white petrolatum on a hot plate. Heat this mixture to 70°C. Dissolve remaining ingredients in water and heat the solution to 70° C. Add the oleaginous phase slowly to the aqueous phase, stirring constantly. Remove from heat and stir the mixture until it congeals.
How do you make zinc oxide face cream?
