Average chemical retention, weight loss and ratings for wafers treated in the termite test

Sample	Chemical retention, kg/m3	Weight loss, %	Rating
MeOH	-	29.7 ± 3.6	3.8 ± 0.5
Catechin	26.0 ± 5.2	16.1 ± 2.1	7.1 ± 0.2
MeOH extract	26.7 ± 4.5	22.6 ± 5.1	7.0 ± 0.0
CPCs	27.1 ± 3.6	20.1 ± 3.3	6.9 ± 0.2
PPCs	26.1 ± 4.3	18.0 ± 1.5	7.0 ± 0.0
LMWPCs	25.4 ± 3.8	13.8 ± 1.6	6.8 ± 0.3

Ratings are based on AWPA standard E1, where a 10 is no attack, 9 is a trace to 3% damage, down to 0 which is failure. Chemical treatment: 6% (w/w).
