Please try to manage line color in axes instead.
loglog(data_1,data_2,data_3,data_4,data_5,data_6,data_7,data_8,data_9,data_10, 'linewidth', 1.5);
hold on
loglog(data_11,data_22,data_33,data_44,data_55,data_66,data_77,data_88,data_99,data_1010, '*');
grid on
xlabel('Time (sec)');
ylabel('Extensional Viscosity (Pa-sec)');
% get current axes
axes1 = gca;
% now add color code
axes1.ColorOrder = [1 1 1;0 0 1;0 0 1;1 0 0;1 1 0];
