Gardeners' World suggests using a 1:4 ratio of perlite to compost or loam.

If you mix it with vermiculite, it helps the vermiculite hold water.

Perlite. Perlite is an amorphous (with no defined crystalline form) volcanic glass (silica or SiO 2) that has relatively high water content, typically formed by the hydration of obsidian. Perlite has the unusual characteristic of expanding and becoming porous when it is heated. It can expand to as much as twenty times its original volume.
