Paraffin liquid is widely used in the cosmetic and pharmaceutical industries as a moisturizing agent due to its ability to lock in moisture and create a protective barrier on the skin. It is commonly found in lotions, creams, and ointments to treat dry or irritated skin conditions like eczema and psoriasis. In the medical field, it serves as a base for topical medications and is used in laxatives to relieve constipation by softening stools. Additionally, it is employed in the food industry as a coating for fruits and vegetables to extend shelf life by reducing moisture loss. In industrial applications, paraffin liquid acts as a lubricant for machinery and a component in polishes and waxes. Its versatility and stability make it a valuable ingredient across various sectors.
