Light Organic Solvent Preservatives (LOSPs) are preservatives that contain insecticides for internal use, and combinations of fungicides and insecticides for external use, and sometimes water repellents. LOSPs may also contain mouldicides. All of these preservative components are incorporated in a solvent carrier such as white spirit.
LOSPs are used to protect timber against insects, including termites, and decay, though they are not intended for use in ground-contact situations.
