This food-grade material is used in food, beverages, and cosmetics to keep oils suspended in water,[2] and its name may be abbreviated as Rosin Glycerides in ingredient lists. It is also used as an ingredient in chewing gum and ice cream production.

Glycerides of wood ester of rosin as a substitute for brominated vegetable oils in citrus oil-flavored soft drinks. In some cases, both ingredients are used together.

Although the pine chemical industry has been a continuous producer of chemical products for centuries, the nature of the industry, its products and terminology have changed. In particular, the original practice of recovering pine chemicals by processing pine exudates has been complemented by solvent product extraction in the wood pulp industry. For many years the industry was known as the "Naval Materials Industry", but that term has gradually been replaced by the more descriptive and meaningful term "Pine Chemicals Industry". The term therefore contains some old terms that are now mostly of historical value, as well as terms from the modern pine chemical industry
