I bought some Jasmine Sambac from Adam at feel oud years ago. Such a pure strong jasmine scent and oil.
I would never macerate musk in it myself. Jasmine would be too over powering.
I would add a few drops into maybe a maceration of musk with sandalwood or moringa oil. Same as I would do rose.
Maybe get some mysore sandalwood, pour the jasmine musk oil into another bottle and then add mysore sandalwood into the bottle with musk grains. The musk grains will still be quite potent to release scent and colour into mysore sandalwood with some jasmine already in there sunk into the musk grains.
It will be really hard to detect musk in the jasmine as you have done it is at the moment and if you do it will be very small amount after a very long time.
@Himanshu Sharma advice is good adding drop by drop daily until your satisfied with the scent.
