Great that you are doing this with ethanol rather than propylene glycol. The commercial products in the UK all seem to use glycol but the FAO guide indicates that a drawback of that is the higher temperature needed to make the extraction which degrades some of the compounds in the extract. Could be a good selling point ... although it is also said that some water-based lotions make it harder to disperse the propolis extract if you are mixing them. The glycol products declare themselves 'alcohol free!!' so the equivalent on the ethanol products should be 'propylene glycol free!!' which seems a better selling point to me

Do you ever get feedback on how yours performs compared to the usual commercial products? Does its ethanol base ever give problems with it drying up?
