Widely used in pharmaceuticals as a topical analgesic and anti-inflammatory agent, especially in creams and ointments for muscle and joint pain. Acts as a counterirritant, creating a cooling sensation followed by warmth, which helps relieve discomfort. Commonly found in products for colds and congestion, such as vapor rubs and nasal inhalers, due to its ability to stimulate respiration and clear airways. Used in dermatological preparations for its mild antiseptic and keratolytic properties. Employed in the production of semisynthetic derivatives like camphor sulfonic acid, which serves as a chiral resolving agent in organic synthesis. Also utilized in the fragrance industry for its strong, penetrating odor in perfumes, soaps, and cosmetics. Historically used as a plasticizer in celluloid and nitrocellulose, improving flexibility and stability. Occasionally used in experimental settings as a solvent additive or crystallization aid.
