Determination of the color stability of an environmentally friendly wood stain derived from laurel (Laurus nobilis L.) leaf extracts under UV exposure

Abstract

This study was designed to develop an environmentally friendly wood stain derived from laurel (Laurus nobilis L.) and determine the color stability of this stain when exposed to UV light irradiation. Wood stains derived from L. nobilis were prepared from aqueous solution with alum and iron mordant mixtures. Scots pine (Pinus sylvestris L.) and Turkish oriental beech (Fagus orientalis Lipsky) wood specimens were used as staining substrates. After treatment with the stain, the wood panels were exposed to UV light irradiation for periods of 100, 200, and 300 hours. Results showed that wood stain derived from laurel (bay) extract provided some color stability after UV irradiation.
