ABSTRACT The invention is concerned with a protective composition for application to a porous substrate, which comprises a protective material for protecting the substrate from deterioration and a carrier therefor, the carrier comprising a hygroscopic liquid. In a preferred embo- diment, the hygroscopic liquid used is ethylene glycol or a hygroscopic derivative thereof. Particularly suitable protective materials are boron-rich compounds which are to be carried into wood as preservatives for suppressing or preventing insect or fungal attack. It has been found that the glycol carrier penetrates the outer portion of the wood more quickly than an aqueous carrier.
