Terpene Resins as food additive  is a safely compound with two benefits.

First, this additive is a polymer of beta-Pinene obtained by polymerizing terpene hydrocarbons derived from wood. It has a softening point of 112 ~118 °C, as determined by ASTM method E28–67 (Reapproved 1982).

Second, Terpene Resins were used or intended for a moisture barrier on soft gelatin capsules in an amount not to exceed 0.07% of the weight of the capsule. Also as a moisture barrier on powders of ascorbic acid or its salts in an amount not to exceed 7% of the weight of the powder.
