Abietic acid has anti-inflammatory effects by inhibiting expression of genes involved in inflammation such as those for tumor necrosis factor-a and cyclooxygenase.
Where is abietic acid found? abietic acid is an irritant in resin and pine wood. How can you avoid contact with abietic acid? avoid products that list any of the following names in the ingredients: • 13-isopropylpodocarpa-7,13-dien-15-oic acid • 7,13-abietadien-18-oic acid • ai3-17273.
Rosin is largely comprised of resin acids, namely abietic acid, dehydroabietic acid, neoabietic acid, dihydroabietic acid, palustric acid, levopimaric acid and pimaric acid. 11,20 the specific balance of this mixture is dependent on the species of the tree, climate, method of extraction and how it is stored.
All but 1 of 5 patients exposed to pine or spruce dusts reacted to the sawdusts, all 5 to colophonium, 3 to abietic acid, 2 to tall oil resin, 3 to wood tar mix and 4 to other wood gum resins. Of the 2 cu patients, 1 was prick and rast positive to obeche, 1 reacted with urticarial dermatitis to punah wood dust on chamber exposure.

Abietic acid dermatitis is a contact dermatitis often seen in association with musical instruments. The main cause is a type-i hypersensitivity reaction to products containing abietic acid, such as the rosin/colophony, which is commonly used as a friction-increasing agent.
Of the resin acids, about 90% are isomeric with abietic acid; the other 10% are mixtures of dihydroabietic acid and dehydroabietic acid.
Dehydroabietic acid (dha or daa), a diterpene, is obtained from commiphora oppbalsamum. Dha has potential as treatment for obesity and metabolic syndrome, obese diabetic kk-ay mice treated with dha showed decreased plasma glucose, insulin, and triglyceride levels.
During the past year (1940-1941) we have observed a number of patients at bellevue hospital suffering from severe acute dermatitis venenata due to wearing underwear shorts processed with a new resin fabric finish containing oleoresin, in which the actual irritant is abietic acid according to schwartz and others.
Abietic acid dermatitis diaper rash airbag dermatitis baboon syndrome contact stomatitis protein contact dermatitis.
Colophony dust may cause dermatitis of the fingers and hands, as well as of the face and neck. In 1930 ramirez and eller [13] first described a chronic fissured hand dermatitis of a violinist who applied colo-phony to the bow of his instrument. Wahlberg [14] found that 6 of 15 musicians allergic to colophony were also allergic to abietic acid.
Contact allergy to abietic acid and more dehydroabietic acid than gum rosin does. The content of abietic acid in adhesive bandages was analysed using reversed-phase hplc,.
Eyelid dermatitis is commonly related to atopic dermatitis or allergic contact dermatitis. 78 volatile substances, tosylamide, epoxy hardeners, insect sprays, and lemon peel oil may be implicated, with many cases of eyelid contact dermatitis being caused by substances transferred by the hands to the eyelids.
Isobornyl acrylate (iboa; cas 5888-33-5), or the isobornyl ester of acrylic acid, can be obtained by a chemical reaction between acrylic acid and camphene, a bicyclic monoterpene. The raw material of iboa, besides containing several, unidentified impurities, might also contain acrylic acid and/or camphene residues (1%).
60 /eq), commonly found in pine resin, has been known to cause contact dermatitis amongst string players and baseball pitchers.
Methyl ester, vinyl and glyceryl esters for use in laquers and varnishes. Manufacture of metal resinates, soaps, plastics, and paper sizes. Component in tall oil used as deodorizing agent in cooling fluids.
Allergenic potential of abietic acid, colophony and pine resin-ha.
The main cause is a type-i hypersensitivity reaction to products containing abietic acid, such as the rosin/colophony, which is commonly used as a friction-increasing agent. Players of bowed string instruments ( violin viola cello double bass ) rub cakes or blocks of rosin on their bow so it can grip the strings.
Abietic acid is an organic compound that occurs widely in trees. It is the primary component of resin acid, is the primary irritant in pine wood and resin, isolated from rosin and is the most abundant of several closely related organic acids that constitute most of rosin, the solid portion of the oleoresin of coniferous trees.
Abietic acid dermatitis is similar to these medical conditions: african blackwood dermatitis, allergic contact dermatitis, irritant contact dermatitis and more.
Pubmed:analysis of abietic acid and dehydroabietic acid in food samples by in-tube solid-phase microextraction coupled with liquid chromatography-mass spectrometry. Pubmed: evaluation of the treatment efficiencies of paper mill whitewaters in terms of organic composition and toxicity.
Resin acids are considered to be the main allergens in colophony (rosin). Tall oils also contain resin acids and may then be potential sensitizers. A resin acid concentrate (pine resin‐ha) together with chinese colophony were included in our standard series and applied on 563 patients with contact dermatitis.
The appendix of contactants in contact dermatitis was instituted with the first edition as the yellow pages. It began with abietic acid and ended with zirnox and it still does. It now has gray edges and, unfortunately, it has not been meticulously edited for consistency or currency.
Objectives: the aim of this study was to evaluate dermal exposure to the resin acids abietic acid, dehydroabietic acid and 7-oxodehydroabietic acid during collecting in sawmills and during sawing in carpentry workshops, respectively.
003% unmodified rosin in the product, assuming that the resin acid content in rosin is 90%, of which 30-50% is abietic acid.

It is clearly a common cause of contact dermatitis, and also can cause occupational asthma as it is a known allergen.
The role of abietic acid--a sensitizer in rosin (colophony)--as the causative agent. Cutis, 27(5):466, 468, 473, 01 may 1981 cited by 2 articles pmid: 7016461.

Once dermatitis appears on the skin, treatment is as for any acute dermatitis/ eczema, with topical corticosteroids, emollients, and treatment of any secondary bacterial infection (staphylococcus aureus).
Grissea, possesses antiproliferative, antibacterial, and anti-obesity properties. Abietic acid inhibits lipoxygenase activity for allergy treatment.
Abietic acid (aa) and dehydroabietic acid (dhaa) are major components of rosin, and both of them are well-recognized causes of skin allergy. Rosin was once widely used for removal of duck feathers in china. In the present study, an analytical method was developed for simultaneous determination of aa and dhaa in duck meats.
It results from either exposure to allergens (allergic contact dermatitis) or irritants (irritant contact dermatitis). Nickel allergy or nickel allergic contact dermatitis (ni-acd), is a form of allergic contact dermatitis (acd) caused by exposure to the chemical element nickel. Urushiol is an oily mixture of organic compounds with allergenic properties found in plants of the family.

Colophony (abietic acid), derived from pine trees, is a complex mixture of over 100 compounds. Colophony is one of the top 10 causes of contact dermatitis and one of the most common causes of occupational asthma. Other allergens associated with pine trees include woodcutter's eczema caused by lichens and liverworts (frullania) living on the bark.
