Showa Denko (SDK), a leading manufacturer and marketer of chemical
products, has found an ingredient that looks set to boost the cosmetics
industry through improving the visibility and appearance of dark circles
around the eyes.
Sodium d-alpha-tocopheryl phospate (TPNa) is a water-soluble vitamin E derivative that contains a unique chemical structure, developed by SDK. TPNa shows anti-inflamatory and moisture-retention effects when used as an ingredient in cosmetics.
Tipically dark circles can be categorised into three types:
-blue circles caused by low microcirculation.
-brown circles caused by accumulated blood-origin pigments.
-black circles caused by slackening or the depression of skin.
The TPNa Vitamin E derivative improves the circulation of the blood and metabolism. It is a single ingredient that has an increasing effect on enzymes that take part in the breakdown and removal of pigments that cause brown circles.
In a clinical test, TPNa was found to improve L* parameters (numerial
values indicating luminosities of skin colors) of the surfaces of lower
eyelids in 82% of those examined.
