ROSIN

ROSIN or Colophony is a yellow, sticky sap tapped from pine & spruce tree trunks. The living trees are 'tapped' and the rosin gum is distilled, producing turpentine oil and colophony. It is the complex natural residue left after distilling off the volatile oils.

Rosin sensitivity can cause contact dermatitis (immediate and delayed) as well as breathing problems, eye and nose irritation and is difficult to avoid, as it’s found in so many everyday things – so awareness is key.
