Used as an antiseptic for minor cuts and burns, boric acid solution helps prevent infection due to its mild antibacterial and antifungal properties. It is commonly applied in ophthalmic preparations for soothing eye irritations and treating conjunctivitis in dilute form. In industrial settings, it serves as a buffering agent to maintain pH stability in various formulations. It is also utilized in the manufacture of glass and ceramics, where it enhances thermal resistance and durability. Additionally, boric acid solution finds use as a wood preservative, protecting against fungal decay and insect damage, and as a household pest control agent, such as for ants and cockroaches, by disrupting their digestive systems. In nuclear power plants, it acts as a neutron absorber in coolant systems to help control reactor activity.

However, boric acid solution should be used with caution, especially in homes with children or pets, as ingestion can be toxic.
