I am not going for the scent... believe it or not... but the properties of the wax itself...
I find the hydrosol and wax component far more therapeutic than the oil for this flower... Personally I don't care for the scent of roses... but my icky skin loves what rose can do for it...
That's very interesting! Makes me curious to try out rose wax as well
I don't have any experience with liquid soap and I only reacted because I made a rose scented soap and thought that was your goal with this soap as well.
On the website of the supplier I normally order my soaping stuff from, it sais that rose wax can be used as a substitute for beeswax in cosmetics or if you want to use it in soap, you need to add 20g for 1kg of soap batter. I think that's about 2/3 of an ounce for 2 pounds of soap or 2%. If I'm not mistaken, liquid soap can be made with up to 3% SF, so I guess you could try adding the rose wax as a 2% SF after saponification? Since it sais 2% of the soap batter and not soaping oils, you might even need less than 2% SF.
Good luck with your experiment! I hope you find a way to get the rose wax incorporated in the soap to get the qualities you're looking for!
