What is EGCg?

Epigallocatechin gallate(EGCg) is the most powerful and most abundant of the catechins found in green tea. EGCg is a potent antioxidant and have a beneficial effect on health.

TECHNOLOGY

PATENT

The first in the world！The novel technology that dissolves water-soluble material in oil without any chemical!

TECHNOLOGY

PUREGREEN Co.,Ltd developed two innovative technologies listed below.

• ①The technology that dissolves water-soluble materials into the oil in concentration.
• ②The technology that suspends fine powder which contains water-soluble material in oil stably without any chemical.

Our patent technology made it possible to dissolve water-soluble materials (which are practically oil-insoluble) in oil in concentration by physicochemical technique without using any of surfactant additives.

Our patent technology made it possible to suspend fine powder which contains water-soluble material in oil without using any oil-suspension agent. Very fine particles are suspended in oil uniformly and stably. After long-hour, suspended particles would be precipitated. But by shaking, stable suspension can be restored right away.

EGCg AQUA

EGCg Aqua is the water-base material in which EGCg is disolved into water in high concentration (10000ppm). Although EGCg is an excellent active ingredient for cosmetics, there are problems of discoloration and degradation when EGCg is applied in water-based cosmetics. Especially EGCg’s high antioxidant effect accelerates discoloration/degradation and that is why the problems have not solved. Because of that, the products containing EGCg have not been commercialized for a long time.

BUT！
The newly developed patented material “EGCg Aqua” has succeeded in preventing EGCg from degradation and discoloration of active ingredients such as catechins.
