No, rosin is used in a lot of “waxes” to provide hardness and toughness. For example, the sealing wax used for wax seals was actually mostly rosin and shellac, because actual wax isn’t strong enough. I’m pretty sure rosin also improves the hygroscopic and thermal properties of beeswax.

By pure chance I went to a museum Saturday night about wax dermatological pathology models, and they shared the once-secret recipe, which is a blend of beeswax, calcium carbonate, and dammar gum (which is a resin somewhat similar to rosin). And indeed, that is hard wax, very unlike pure beeswax.
