- Outdoor Skin Protectant's ingredient is an extract derived from the englemanii Opuntia, Prickly Pear Cactus. cacti are free range cacti harvested from a select area on the Edwards Plateau in West Texas. CACTUS JUICE TM cacti are not cultivated to insure their natural high content of vitamins and minerals. Natural, high quality cacti contain minerals, vitamin C, the vitamin A precursor, B-carotene in levels comparable to spinach, along with saccharides, carbohydrates, simple sugars and a naturally occurring form of rodine. These and other compounds insure that Prickly Pear Cactus in its natural environment is rarely attacked by insects. What is unique about the Prickly Pear Cactus extract is, while a proven insect repellent, the cacti have been used as a food source for centuries. When the cactus extract is combined with the non-toxic water based carrier, SPF 20 sunscreens, a light citrus scent and inert ingredients, we have finally re-discovered the Prickly Pear Cactus. 8 oz.
