I am sorry about
your husband's problems but want to point out that these compounds are chemically distinct.
Glycerol (3 OH groups) and glycol (a diol; 2 OH groups); both are alcohols
Glycine is an amino acid
Glycyl is glycine connected (through a peptide bond) to another amino acid
In other words, glycine and glycyl compounds are quite different from the alcohols that you think might cause allergic reactions. I do agree that the alcohols are in very many products.
Glycine is in all proteins, including those in your body
