Black crust at the corner of a cat’s mouth can come from injury, folliculitis, or other skin diseases. For an injury, just disinfect the wound.
If itching appears, take the cat to a vet to find the cause. For folliculitis, clean with saline and apply an antibiotic spray or ointment. Also adjust the diet to avoid greasy food.
