nope. IP Aliases are depreciated, baby!

If eth0:0 has FIX IP address, you should try SNAT: 

# iptables -A POSTROUTING -t nat -s 192.168.0.0/24 -j SNAT --to IP_of_eth0:0

Ip Aliases practically don't exist anymore, they are just one other ip
address on eth0 marked with a compatibility flag for the old ifconfig.
(Use ip/iproute2 and you see what I mean).

So don't use MASQUERADE and eth0:0, but instead use SNAT and the second ip
of eth0 (aka the one on your eth0:0)
