This is a dark clay ideal for face masks and mud mask applications. Its color ranges from light gray/green to dark gray. Due to its high content of minerals, sea clay draws oils from the skin, and is rich in algaes, macro- and micro-minerals, as well as sodium and sulphur. Sea plants, seawater, sea salt and oceanic clay have long been popular physical-therapy ingredients in Europe. Recommended as medical therapeutic agents as early as 1578, seawater and sea derivatives were administered for rheumatism and general rehabilitation. If you will search online, you will come across a couple of companies which supply spas and salons with expensive body wrap products and you will see that sea clay is an important ingredient in body wraps to lose inches and cellulite. Sea clay is also recommended for use on horses to apply on minor cuts, scabs and so on. For horses it may be used after strenuous workouts (cold to cool and tighten legs and muscles, to pack hooves and cool them after work on hard ground) (warm to reduce stiffness and maintain mobility, to relax and soothe tired muscles). Please consult a veterinarian prior to treating any animals. Sea Clay: Origin - USA; CAS# - 1332-58-7; INCI - Kaolin, Aluminum Silicate; Mesh - 200
