Paraffin liquid is widely used in the pharmaceutical and cosmetic industries as a moisturizing agent due to its ability to lock in moisture and create a protective barrier on the skin. It is a common ingredient in lotions, creams, and ointments, particularly for treating dry or irritated skin conditions like eczema and psoriasis. In the medical field, it serves as a base for certain topical medications and is also used as a lubricant for medical equipment. Additionally, it finds applications in the food industry as a coating for fruits and vegetables to extend shelf life by reducing moisture loss. In industrial settings, paraffin liquid is utilized as a lubricant for machinery and as a component in the production of candles and polishes. Its versatility and non-reactive nature make it a valuable substance across various sectors.
