USE OF COPAIBA OIL (Copaifera paupera) FOR THE PRESERVATION TREATMENT OF<br />

SPECIES SAMAÚMA (Ceiba pentandra)<br />

ABSTRACT<br />

This study aimed to evaluate the efficiency of copaiba oil (Copaifera paupera) as a <strong>na</strong>tural<br />

wood preservative of the specie Ceiba pentandra. The specimens of C. pentandra had the dimensions<br />

of 2.0 x 10.0 x 40.0 cm, and were submerged for a period of 5 minutes in the solutions of copaiba oil<br />

(T2) and copaiba oil + ethereal solution (T3). After soaking, the specimens were placed on platforms<br />

in an open area for a period of three months. There were conducted two evaluations to verify the<br />

effectiveness of preservative treatment. The first right after the removal of specimens from the area<br />

where they were exposed and the second after a sanding surface. The results showed that the pure<br />

copaiba oil and associated with ethereal solution contributed to the reduction of the mass loss of<br />

specimens of C. pentandra. About the efficiency of the preservative solutions, there was no significant<br />

difference between treatments, indicating that pure copaiba oil and associated with ethereal solution<br />

is not effective in preserving the wood of C. pentandra.<br />
