This company is advertising its citric acid by emphasizing a few of its properties and also mentions the other acids the company produces.

Why Pfizer citric acid is known as “Nature’s Acidulant.” Nothing else adds such natural zest. That’s why Citric acid is the most used acidulant. And why Pfizer takes such care in its production. Pfizer citric enhances natural flavor– never intrudes any adverse flavor notes of its own. Because of its unusually clean taste, Pfizer citric is compatible with more food products than any other acidulant. It is extremely soluble so it can be added dry or as a concentrated stock solution. Available over a wider range of particle sizes than any other food acids. Andit has useful chelating properties. Of course, citric acid is just one of the Pfizer acidulants. Others are Tartaric and Fumaric acids. Parts of the comprehensive line of Pfizer food ingredients. For more information about Pfizer acidulants just mail the coupon. 

I find it interesting how it mentions “nature’s acidulant” in the title but then the only thing about nature mentioned is that it adds a natural zest. This ad markets Pfizer citric acid as a natural flavor enhancer that doesn't add any unwanted aftertastes. It emphasizes the product's versatility and easy solubility, positioning it as a reliable tool for a wide range of food and drink formulas. Georgia Salcau
