The Fox Labs spray isnt legal in CA because it lacks the proper specifically worded warning on the canister. CA doesnt have restrictions on strength or the type of spray.
It does however have to have a warning which states:
"WARNING: The use of this substance
or device for any purpose other than self-defense is a crime under
the law. The contents are dangerous--use with care."
Below is the exact requirements for defensive sprays in CA.
IMHO, the Sabre Red and the Bodyguard Hi-Power are stronger sprays anyways.

possess, or use tear gas and tear gas weapons for the projection or
release of tear gas if the tear gas and tear gas weapons are used
