Some synthetic musks are crystalline solids and as a result are often sold either pre-diluted or mobilised in something to make them liquid and easier to handle.
There are a huge number of musks on the market but the two you are working with are not the best choices - Musk Ambrette is prohibited by IFRA and Musk Ketone is banned in some countries.
These are some of the musks I use routinely:
Ambrettolide (this synthetic is the same as the musk in Ambrette Seeds - a very good quality diffusive musk, slightly fruity)
Cashmeran (interesting - liquid and easy to handle - but hard to use successfully because it has a musty, almost mushroom tone to it that needs carefull blending. When it works it very warming and velvety)
Celestolide (crystals that are slow to dissolve in ethanol. Adds more brightness than the others.
Ethylene brassylate (also called Musk T, widely available, liquid at room temp and cheap, good fixative properties and easy to use)
Exaltolide (solid at room temp but melts easily, very widely available and used macrocyclic musk)
Galaxolide (very widely available and used, especially in functional products. Often sold as 50% in DEP as its solid otherwise. A polycyclic musk which is
not biodegradable)
Muscone (this is the musk that is in musk deer pods but synthesised. Lovely fine musk that has the edge over the others for its erogenic quality)
l-Muscone is a more expensive and even finer quality - just the L isomer.
Romandolide (not so widely available, similar in scent to Galaxolide but macrocyclic and biodegradable)
Tonalid (crystalline solid again but a bit easier to dissolve than some. Often disparagingly referred to as laundry musk its nevertheless a good fixative and very widely used)
Velvione (another very fine musk of great diffusion, rather like ambrettolide by less fruity and even softer. A great exalting agent)
There are plenty of others. I nearly always use musks in combination rather than using just one in a composition. In particular you can get good effects by using very tiny amounts of ambrettolide or velvione alongside one of the cheaper musks. Both work well with Exaltolide and Romandolide.
Another option is
Auratouch from Givaudan - a blend of several of their musk products which I think also includes a captive.
