I recommend that hands be washed thoroughly and rinsed even more
thoroughly with NO hand lotion before entering the assembly area. Here
is a typical formulation of a hand lotion
Aqua (water)
Paraffinum liquidum (mineral oil)
Propylene glycol (hygroscopic surfactant)
Propylene glycol stearate (hygroscopic and ionic ester)
Cetearyl alcohol
Stearic acid (ionic carboxylic acid)
Parfum (fragrance)
Triethanolamine (ionic saponifier)
PEG30 (polyethylene glycol, hygroscopic)
Lanolin (animal fat)
Methylparaben (goodness knows!)
Propylparaben (ditto)
Sodium lauryl sulfate (ionic surfactant- hygroscopic)
PEG75/lanolin blend (see PEG30 and lanolin)
P-chloro-M-cresol-BHT (whatever that may be)
Colours
This is taken off the bottle of a well known make.

Which of these products would you like to see on your assemblies?

It is dangerous to allow a specific "safe" make: operators will still
prefer their own and there is no way you can prevent them from using it.
As for so-called anti-static ones: this is a sales gimmick that means
that they have an extra dose of hygroscopic surfactants which is one of
the last things you wish on an assembly. So, if you wish to respect the
electrical integrity of your assemblies: NO HAND CREAMS.
