Showa Denko America, Inc. has introduced TPNa (sodium tocopheryl phosphate), a water-soluble vitamin E ingredient for skin care. Available in powder form, TPNa is enzymatically catalyzed and converted to vitamin E immediately in the skin, so all the benefits—preventing inflammation, protecting the skin from harmful UV rays, and scavenging free radicals—can start working faster. TPNa is an active ingredient in a designated quasi-drug in Japan.
