SDK to Launch New Water-Soluble Vitamin E Derivative for Skin Care

Showa Denko K.K. (SDK) will soon start full-scale marketing of new water-soluble vitamin E derivative TPNa (tocopherol phosphate sodium) for use in skin care products.

TPNa was approved by the Ministry of Health, Labor and Welfare as a new ingredient for quasi medicine under the Pharmaceutical Affairs Law in June 2004. Following the completion in February 2007 of the two-year safety test period in accordance with the law, SDK has decided to begin full-scale marketing of the product.

Vitamin E prevents oxidation of lipid in the skin by removing active oxygen caused by ultraviolet rays. However, vitamin E is chemically very unstable and readily loses its effect as a result of oxidation. Furthermore, as vitamin E is an oily matter, it is difficult to blend vitamin E in cosmetics.

SDK’s TPNa has solved such problems as it has the following advantages owing to its special chemical structure:

  • 1.Readily soluble in water; can be easily blended in cosmetics
  • 2.Readily absorbed through the skin and quickly transformed into vitamin E in the skin
  • 3.Chemically very stable

In addition, TPNa has anti-inflammatory and moisture-retention effects. Thus, TPNa is expected to be effective in preventing skin troubles.

SDK has already provided base materials for cosmetics centering on stabilized vitamin C, including ascorbyl phosphate magnesium (APM) and ascorbyl phosphate sodium (APS) for skin brightening as well as sodium ascorbyl 2-phosphate 6-palmitate (trade name: Apprecier) for wrinkle care.

Together with the new water-soluble vitamin E derivative TPNa , SDK is aiming to increase the annual sales of base materials for cosmetics from ¥1 billion at present, to ¥2.5 billion by 2010.

The operation is positioned as one of the “new growth driver” businesses under the ongoing business plan, the Passion Project, that runs from 2006 through 2008.
