Not necessarily. Drinking water is a form of peristalsis, and it is involuntary.
Esophagus is an anatomy organ and hasn't a chemical formula.
The gatekeeper of the esophagus is called the lower esophageal sphincter (LES). It is a muscular ring at the junction of the esophagus and stomach that helps to prevent stomach acid from flowing back into the esophagus.
The passageway for food that is behind the trachea is the esophagus. After swallowing, food travels down the esophagus to reach the stomach for digestion, while air goes down the trachea to enter the lungs for respiration.

The muscles in the esophagus are primarily involuntary. The upper third of the esophagus contains skeletal (voluntary) muscle, allowing for some conscious control during swallowing. However, the middle and lower portions consist of smooth (involuntary) muscle, which operates automatically to facilitate the movement of food. This involuntary action is essential for the continuous process of digestion.
In taking a drink from a glass, you make several voluntary movements, the last being swallowing; which leads to several involuntary movements of esophagus, throat, and stomach.
Well, an example of involuntary is your esophagus or intestines. We were taught that digestion is an involuntary process, so I am sorry but I do not know of any voluntary muscle examples.

From the mouth to the stomach is the esophagus.
The esophagus is primarily composed of two types of muscle fibers: skeletal muscle and smooth muscle. The upper third contains striated (skeletal) muscle, which allows for voluntary control during swallowing. The middle third is a mix of both muscle types, while the lower third is predominantly smooth muscle, facilitating involuntary peristalsis to move food toward the stomach. This arrangement enables efficient transport of food through the esophagus.
