I'd like to know if these ingredients are vegan. C10-18 TRIGLYCERIDES, CAPRYLIC/CAPRIC?

Caprylic acid is the common name for the eight-carbon saturated fatty acid known by the systematic name octanoic acid. Its compounds are found naturally in the milk of various mammals, and as a minor constituent of coconut oil and palm kernel oil.
It doesn't sound vegan if it's a component of mammalian milk.
