Scented chalk
Liquid chalk with fragrance added. The scent does not improve friction.
Mint, citrus, and "clean" smells are marketing. SportmediQ's listing includes fragrance in the ingredient line. Smell does not absorb sweat. It can bother people in a small gym and it is one more thing to react to.
Prefer unscented if you share a room or you have sensitive skin. Confirm "unscented" on the label, not in a review.
