Will Bora-Care penetrate unfaced foam insulation board?

I've read that Bora-care will penetrate wood up to 4 inches thick, so I'm wondering if Bora-care technical department has determined whether BC will penetrate 2 inches of unfaced ridged foam board insulation. I installed 2" foam board against my crawl space block wall foundation a few years ago and am considering spraying the foam if BC will penetrate it and reach the face of the masonry block. Thanks


 Per the product label, "Bora-Care solutions may be used on all non-food contact surface cellulosic materials including wood, plywood, particleboard, paper, oriented strand board (OSB), cardboard (non-food packaging material), wood composite structural components, concrete, block, brick, metals, PVC plumbing pipes and other non-cellulosic materials found in structures. Apply Bora-Care solutions only to bare wood, plywood, particleboard and other cellulosic materials where an intact water-repellent barrier, such as paint, stain or sealer, is not present."
