The predecessor of Wenzhou Qingming Chemical Co., Ltd. was the former state-owned Wenzhou Qingming Chemical Factory. Wenzhou Qingming Chemical Factory was founded in 1942 and is one of the earliest fine chemical factories in China. In July 2002, the company successfully restructured into a limited liability company based on inheriting its existing advanced technology, equipment, and talent resources. The following year, it passed ISO9001 international certification. In 2005, the company relocated to a new location and settled in Wenzhou Industrial Park, taking its production and business scale to a new level. Now, the company has developed into a professional production base for food additives and epoxy resin curing agents with significant influence in the country.

The company currently mainly produces food additives mainly consisting of sorbitol anhydride fatty acid ester series (Sipan series) and polyoxyethylene (20) sorbitol anhydride fatty acid ester series (Tween series); Epoxy resin active toughening agent and curing agent series products mainly including CMP410, methyl tetrahydrophthalic anhydride and polydecanoic anhydride, and industrial surfactant series products mainly including PEG264 oleate, castor oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether, etc. After years of efforts to improve technological content, cooperating with universities and research institutions, continuously adjusting product structure, and developing marketable new products, we have now become a distinctive professional production enterprise for fine chemical additives, and our products are renowned in both domestic and international markets.

As a director of the China Food Additives and Ingredients Association, vice chairman unit of the Thickening Emulsifying Quality Improver Professional Committee of the China Food Additives and Ingredients Association, and vice chairman unit of the Zhejiang Food Additives and Ingredients Industry Association, our company produces Span and Tween series of food additives, which have won the Feitian Award at the first National Food Additives Exhibition; In 1992, he won the Excellent Award at the National Light Industry Expo.
