Greeting

Responding to challenges with " ideas that transcend preconceived notion. "

More than 20 years ago, we succeeded in making catechin, a water-soluble component of tea that was considered difficult by existing concepts, to be physically oil-solubilized, and acquired an international patent.

Since then, we have expanded the range of applications for oil-solubilized catechins to cosmetics and foods, and have continued to provide safe and secure ingredients and products that do not use chemical ingredients and have high antioxidant power, contributing to society.

At first, we had repeated trial and error to stabilize catechins, but with the cooperation of universities and other institutions, we were the first in the world to make catechins, the water-soluble active ingredient contained in green tea, oil-soluble and stabilized.

We succeeded and obtained an international patent (W001/95865A1).

Currently, we supply new raw materials to many cosmetics and food manufacturers, promote the development of safe and secure products that specialize in plant-based products, and manufacture OEM brand products for domestic and foreign manufacturers and retailers.

On the other hand, we succeeded in stabilizing catechins by making them oil-soluble, but we have long been trying to find a way to preserve catechins in water-soluble liquids that are soluble in water-soluble solvents and have excellent long-term stability.

We have been working on research and development at HPG Co., Ltd. to make it possible.

Polyphenols, which originally contain catechins, are very unstable because they are easily oxidized by oxygen dissolved in water, oxygen in the air, and light.

Furthermore, when it is dissolved in an aqueous solvent, its useful action such as the expected active oxygen scavenging action is reduced, and there are problems with its storage stability, such as discoloration due to oxidation.

In this way, there were preconceived notions such as catechin, which is a water-soluble active ingredient, does not dissolve in oil and even if catechin is dissolved in water, it is very unstable and oxidizes quickly.

However, we have succeeded in developing an aqueous solution composition containing catechins with excellent storage stability with an idea that transcends established concepts (patent application started in August 2021, international patent published in March 2023),

We believe that HPG Co., Ltd. can respond to various issues with high performance in all possible applications.

HPG Co., Ltd. focuses on "people, the earth, and the environment", challenges without being bound by common sense, and always delivers products and services of stable quality with new technology to everyone with "safety, security and joy".
