TPNa™

Sodium Tocopheryl Phosphate. TPNa™ by Resonac (formerly Showa Denko) is a Resonac's original vitamin E derivative. It is water-soluble powder, which can deeply penetrate the skin. Once absorbed in the skin, it is readily converted to the active tocopherol via hydrolysis by phosphatase and has a variety of effects.

• It can be expected to improve water-holding capacity through promoting ceramide synthesis and to achieve an anti-pollution effect by its high anti-oxidative and anti-inflammatory effect.
• It is an officially approved active ingredient for Japanese quasi drugs due to its effectiveness in preventing rough skin.
• TPNa™ complies with NMPA (CN) regulations.
