Anhui Tonghui Perfume Co., Ltd.

Anhui Tonghui Spice has produced cooling agent raw materials since 2005 and describes itself simply as a cooling raw material factory. Its catalogue covers the physiological cooling compounds and the mint chemicals that go with them, including menthone and peppermint oil, and the company supplies application support alongside the material itself.

Annual production capacity is stated at more than 6,000 tonnes. Output is sold under three brands, Qingliangfeng, Polar Seal and Gongming, which between them span the different cooling profiles the company offers, and it works on tailored product blends for individual customers rather than only shipping standard grades.

The factory is in the Southern New District of Bozhou, Anhui, a city better known as a centre of the Chinese medicinal herb trade. The company's public site does not state site area, headcount or certification.
