Many thanks Perry and Billichemist. Since I posted this I managed to pre-dissolve the zinc ricinoleate first separately in the propanediol. 

Great feedback regarding Polyfix XRC 25GP Billichemist. Thanks! I’d love to try it but I am struggling to find a supplier that would sell small quantities here in the UK. Apologies but I don’t quite understand what you mean by the interaction between -N/-S products and the zinc. I’d be grateful if you could expand a bit. 

Thanks again!

Anybody? Apparently there is a product called Polyfix ZRC 25 GP which is a water soluble zinc ricinoleate but I was hoping someone might be able to point me in the right direction.
