Particle size, z potential and PDI of nanoparticles prepared with different polymers proportions (mean ± S.D.)

Proportion	Particle size (nm)	Z potential Z (mV)	PDI
30:70	39.7 ± 5.58 a	22.9 ± 4.2 a	0.306 ± 0.080 a
40:60	40.8 ± 2.07 a	24.3 ± 2.4 a	0.359 ± 0.019 a

Means with different letters within a column are significantly different (P < 0.05)

30:70 = 30% Eudragit RL y 70% de Eudragit RS

40:60 = 40% Eudragit RL y 60% de Eudragit RS
