Two points about your list.
 
One: hydrolyzed vegetable protein.    In the past, processors could use
unspecified hydrolyzed protein as an ingredient.  The protein source could
be casein.  Under the latest FDA rules, a casein-containing ingredient must
be listed as hydrolyzed milk protein or the equivalent.  Hydrolyzed
vegetable protein can no longer  contain casein or whey.   Either way,
however, hydrolyzed, by definition, means broken down into constituent
amino acids.  It is conceivably possible but highly unlikely that they
would cause reactions.  After all, the safest, most non-allergenic infant
formulas are made from hydrolysates.
 
Two: lactates.  Lactates are salts of various minerals.  They are not
proteins.  They contain no milk products at all.
 
Hope this helps,
