Minoxidil Cat Contact Urgent

About 45 minutes ago I interacted with my cat (F, 5, Spayed, Domestic shorthair, 9lb) and kissed her head. I applied minoxidil to my mustache line about 2.5 hours prior to this. I know it is toxic to pets when ingested and you’re supposed to wait until the product is dry to interact (and it was dry) but do I need to be worried?? She isn’t currently showing any symptoms and I immediately washed her head with soap and warm water.
