    Dear Friends,

    I am looking for the electric overhead mixer. The propellers and the rod are made from Zinc-plated steel. Is it good for mixing facial cream?

    Thanks

    No. Cr in stainless (esp. 316) imparts resistance to the entire material whereas Zn plating is only a surface treatment. Tho Zn plated is cheaper, constant exposure to moisture - formulas, cleaning/sanitization , high and low pH, oxidizers like hypochlorite - and physical wear will exhaust/scratch the Zn layer generally and in detail reducing the impeller life.
