Questions about Castor oil, Ph.Eur. native, extra pure, 1 l, glass
What is this article?
Castor oil, Ph.Eur. native, extra pure, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Essential oils & fragrances, inside Natural products & essential oils, in Produits chimiques de laboratoire et industriels.
An essential oil is the volatile fraction distilled or pressed from a named plant part. The species, the chemotype and a stated component, when the seller gives one, are the specification. A fragrance compound is a formulated mixture. The two should not be treated as the same bottle.
A natural product is a molecule extracted from a plant, an animal or a microorganism, or a mixture of those molecules. An essential oil is the volatile fraction. The useful specification is the source species, the plant part and, where it exists, the stated content of a marker compound. Two oils with the same common name are not the same article. Marker compounds are identified on PubChem and named by IUPAC.
