Are there any?
Not mixer. But few people mention specific CoinJoin implementation with few participant works.
What's the point of a mixer if you don't get a fresh entirely new bitcoin address with no connections to any other bitcoin that could be "tainted"
Break link movement of your coin?
Speaking of tainted bitcoins. Some people said tainted bitcoins aren't a thing. Well tornado cash crackdowns seem to suggest otherwise.
What actually a thing is Bitcoin
is not fungible. Some government/company use that fact to determine whether a coin is "tainted" or not by their own definition/classification.
OP, risking the fact that many forum members will be angry at me for this simple suggestion, but if you're willing to accept the trade off, and merely want a little untraceability/privacy for your transactions, then you can use Wasabi Wallet. Anyone can say, "No, Wasabi Wallet is bad", but it's your decision only IF you accept the trade off.
It's not difficult to detect whether an UTXO comes from Wasabi CoinJoin though, which doesn't meet OP criteria.
