Para-Aminobenzoic Acid (PABA) is an organic compound that belongs to the vitamin B complex group. It is a white, crystalline substance that is soluble in water and alcohol. PABA is naturally found in foods such as whole grains, eggs, and dairy products. It plays a role in the synthesis of folic acid, which is essential for cell growth and metabolism. PABA is also known for its use in sunscreen products due to its ability to absorb ultraviolet (UV) light. While it was once a common ingredient in sunblocks, its popularity has declined due to potential allergic reactions in some individuals. Overall, PABA is important in both nutrition and skincare.
