## Now, 1,3-butelyne glycol has FDA acceptance as a plasticizer in cellophane used for food packaging. 

## So NOW take another look at 1,3-BG’s potential for food, drug, and cosmetic products. 

We think you ought to consider the use of 1,3-butylene glycol where a low-toxicity glycol is desirable. 

As a humectant, for example, 1,3-BG is relatively unaffected by temperature or humidity changes. Our tests show 1,3-BG acquires and maintains atmospheric moisture at nearly constant levels in the 20-50% humidity range. Other polyols tend to show a pronounced slope with moisture retention poor at low humidity, excessive at high humidity. 

Our 1,3-butylene glycol is an extremely pure (99.0%) four-carbon diol, with toxicity, humectant and solvent properties well suited to food, drug, and cosmetic products. 

Celanese is busily adding to an already extensive body of toxicological data on 1,3-BG. It’s all available to you. Write to: Celanese Chemical Company, Dept. 594-L, 522 Fifth Avenue, New York 36, N.Y.

This advertisement is particularly technical, with the specialized functionalities of 1,3-BG clearly outlined. It serves to highlight the advantages of it while establishing it as superior than its competitors.
