Rosin, a collective name for resin acids, is found naturally in extractives from pine, spruce and larch trees and therefore ends up to a very large extent in the tall oil after cooking. Allergies to rosin are present and we can identify and measure the rosin content in products.
Small quantities can accompany the pulp and end up in different products and usually do not cause any problems. In a Danish study of 2,000 patients with eczema, however, 3.7% had allergies due to skin contact with rosin. The greatest risk of suffering from rosin allergy is with prolonged skin contact with adhesive materials such as plasters, bandages, cosmetics, bandages and more. For those who suffer from contact allergies caused by rosin, there is a risk that it will last for the rest of their lives.
In some markets, there are limit values for the content of rosin and we have therefore recently received a number of assignments and requests for analysis of rosin content in pulp to be used in hygiene products.
Examples of products that can be found in: Cosmetics, plasters, tape, paint, soap, rust protection, cutting fluids etc.
Synonyms: natural resin, tall oil resin, pine resin, resin oil, raisin, rosin oil,
rosin rubber, rosin tall oil (abietic acid, abietin alcohol, abietyl alcohol)
We have methods to analyze rosin content in pulp by analyzing resin acids by gas chromatography. Sometimes three of these resin acids, abietic acid, dehydroabietic acid and 7-oxodehydroabietic acid are used as markers for rosin. To be able to perform the analysis, at least 20 g of pulp is needed.
