Comment (by tscrim):

 Replying to [comment:24 tscrim]:
 > I am guessing it would be too much to ask for a Garside-type structure
 coming from the projection onto S,,n,,, where every element can be written
 as `xy^k` where `x` is the natural section of S,,n,, and `y` is some
 special element in J,,n,, (similar to a normal form for the braid group
 elements, where `y` corresponds to the section of the long element).

 A Garside-type structure would not work here because that is used for
 passing from the braid monoid to the braid group. So I really don't think
 this will work for the cactus group.
