Latest patents enhance manufacturing process for acesulfame potassium high intensity sweetener products

DALLAS & AMSTERDAM--(BUSINESS WIRE)-- Celanese Corporation (NYSE:CE), a global specialty materials company, today announced it has been granted four new patents by the United States Patent and Trademark Office (USPTO) covering manufacturing process improvements to produce acesulfame potassium (Ace-K).

The patents granted by the USPTO (US 10,023,546; US 10,029,998; US 10,029,999; and US 10,030,000) all provide substantial technology advantages to Celanese and its customers for the production and quality of Sunett® Ace-K sweetener. With the issuance of such patents, these technology advantages are recognized as exclusive to Celanese, thereby increasing the benefit to customers by ensuring the highest quality and reliability standards of its Sunett® portfolio.

“As the inventor and only Western producer of Sunett® Ace-K, Celanese has developed a series of best practices to deliver one of the industry’s highest quality artificial sweeteners, ensuring product purity, supply reliability and accountability,” said Scott Sutton, Chief Operating Officer. “Celanese continuously invests in manufacturing and quality improvements and is dedicated to robust research, development and customer support for the sweetener products manufactured by our patented process. We are pleased that the USPTO has granted Celanese these patents, which will continue to place Celanese as a leading, global high intensity sweetener manufacturer. We intend to vigorously defend our patented technology against unlawful importation and uses in the United States.”

Two hundred times sweeter than sugar, Sunett® Ace-K is a zero-calorie, dental-friendly, high-intensity sweetener manufactured in a single-purpose plant with unique and patented processing steps. It provides optimized applicability and consistent sweetness profiles for better taste and excellent blending characteristics. Demand for high quality Ace-K continues to grow as consumers look for alternatives to full-sugar products.
