Thin films of leading commercial high-sun-protection-factor sun products with UVA (ultraviolet 340- to 380-nm radiation) claims were compared to a new, high-efficiency sunscreen product that was designed to resist breakdown from exposure to UV radiation. The relationship between the thickness of the topical application of sunscreen films and the durability and efficacy of the product has significant clinical implications for physicians.

Abstract-Acute and chronic exposure to nonphysiological doses of ultraviolet radiation leads to variety of changes of skin ranging from sun-burn, erythema to skin cancer. For skin protection from deleterious effects of sunlight, sunscreen products are used in various forms having chemical and physical filters. However, synthetic sunscreen formulations are reported to cause adverse effects. Thus the present study was planned to evaluate the sun protection factor (SPF) of leaves extract of Murraya koenigii for their application as herbal sunscreens. The results suggested that the occurrence of active compounds responsible for ultraviolet absorption can be extracted for use in sunscreens preparations as better, cheaper and safe alternative to harmful chemical sunscreens. Keywords: UV radiations, SPF, Murraya koenigii
