As a blogger, I recently came across an interesting topic about how benzalkonium chloride and zinc oxide are used in eye care products. These two ingredients are commonly found in over-the-counter eye drops and ointments, mainly due to their antibacterial and astringent properties. Benzalkonium chloride acts as a preservative and disinfectant, while zinc oxide is often used to soothe and protect the eye. These ingredients work together to keep our eyes healthy and clean, while also providing relief from various eye irritations. It's fascinating to learn how everyday products contain such essential components for our eye care.
