Preservatives - inactivation by cellulose derivatives
Dear clever heads,
if preservatives inactivated by cellulose derivatives
is there any chance to preserve HEC hydroxyethyl cellulose?
Which preservative can be safely used with HEC?
Many thanks.

speaking from experience, they are not ‘inactivated’ by cellulose derivatives; rather, their efficacy is reduced
i.e. the preservatives in question will still work, but you’ll need to use them at a higher level
