ABSTRACT:
An improved sunscreen protection and insect repellent combination composition having an SPF factor of about 2 to about 50 and further having an unexpected, unusually long efficacy period when used in rainy conditions or prolonged periods of high humidity, such as in a tropical or sub-tropical rain forests, or the like, and after the wearer has been underwater. The composition forms a stable emulsion lotion that is easy to store. No special precautions are required by the person who applies the lotion. The composition includes a sunscreen agent, an insect repellent, including 3-[N-Butyl-N-acetyl]-aminopropionic acid, ethyl ester ("IR3535.TM."), an emulsifying agent, and a film former, all in an aqueous solvent. The composition forms a thin film on the skin, but it is non-greasy to the touch. The lotion is easily removed by scrubbing with soap and water.
