Colophony (Rosin) Allergy: More Than Just Christmas Trees Clinical AND Health Affairs Colophony (rosin) allergy: more than just Christmas trees BY LINDSEY M. VOLLER, BA; REBECCA S. KIMYON, BS; AND ERIN M. WARSHAW, MD Colophony (rosin) is a sticky resin derived from pine trees and a recognized cause of allergic contact dermatitis (ACD), a type IV hypersensitivity reaction.1 It is present in many products (Table 1) and is a common culprit of allergic reactions to adhesive products including adherent bandages and ostomy devices. ACD to colophony in pine wood is less common although has been reported from occupational exposures,2 as well as consumer contact with wooden jewelry, furniture, toilet seats, and sauna furnishings.3 We present a patient with recurrent contact dermatitis following exposure to various wood products over the course of one year.

The method is based on a generic solid-phase extraction procedure, using three sorbent phases in two cartridges that are connected in series, hence covering a wide range of polarities, followed by liquid chromatography coupled to high-resolution mass spectrometry. The acquisition was performed in the full-scan and data-dependent modes while working under positive and negative ionisation conditions. This method was applied in order to assess the natural toxins in the Ter River water reservoirs, which are used to produce drinking water for Barcelona city (Spain). The study was carried out during a period of seven months, covering the expected prior, during, and post-peak blooming periods of the natural toxins. Fifty-three (53) compounds were tentatively identified, and nine of these were confirmed and quantified. Phytotoxins were identified as the most frequent group of natural toxins in the water, particularly the alkaloids group.

  • Other Data Relevant to an Evaluation of Carcinogenicity and Its Mechanisms
    WOOD DUST 173 3.5 Experimental data on wood shavings It has been suggested in several studies that cedar wood shavings, used as bedding for animaIs, are implicated in the prominent differences in the incidences of spontaneous liver and mammar tumours in mice, mainly of the C3H strain, maintained in different laboratories (Sabine et al., 1973; Sabine, 1975). Others (Heston, 1975) have attributed these variations in incidence to different conditions of animal maintenance, such as food consumption, infestation with ectoparasites and general condition of health, rather than to use of cedar shavings as bedding. Additional attempts to demonstrate carcinogenic properties of cedar shavings used as bedding materIal for mice of the C3H (Vlahakis, 1977) and SWJ/Jac (Jacobs & Dieter, 1978) strains were not successful. ln no ne of these studies were there control groups not exposed to cedar shavings. 4. Other Data Relevant to an Evaluation of Carcinogenicity and its Mechanisms 4.1 Deposition and clearance 4.1.1 Humans No studies of the deposition of wood dust in human airways were available to the Working Group. Particle deposition in the airways has been the object of several studies (for reviews, see Brain & Valberg, 1979; Warheit, 1989). Large particles (? 10 ¡.m) are almost entirely deposited in the nose; the deposition of smaUer particles depends on size but also on flow rates and type of breathing (mouth or nose); there is also inter-individual variation (Technical Committee of the Inhalation Specialty Section, Society of T oxicology, 1987). Particles deposited in the nasal airways are removed by mucociliary transport (for reviews, see Proctor, 1982; Warheit, 1989).

  • NATURAL SPIRIT VARNISH RESINS SHELLAC Production
    CHAPTER 5 NATURAL SPIRIT VARNISH RESINS SHELLAC ALTHOUGH shellac is not used in the varnish trade in such large quantities as other natural and synthetic resins it has attracted a considerable amount of interest. Much research and development work has been done. Source.—Lac is the secretion of an insect, Laccifer lacca, which swarms on the twigs of special trees. A comprehensive list of host trees is given by Parry.1 The insects extract sap from the twigs but its constitution and the nature of the process involved for the production of lac are not com- pletely understood. Gibson 2 suggests that if the food for the lac insect could be produced synthetically, the insect could be cultivated under ideal conditions. The greater part of the world's shellac supply comes from India. Assam, Burma, Indo-China and Siam supply smaller quantities. Attempts have been made to produce lac in Abyssinia. Two crops of lac are produced yearly. Climatic influences seem to alter the properties of the lac produced. In the areas west of Calcutta lac has a yellow or orange colour ; in Assam it is pale red, and dark red in Siam.3 Other variations in properties may be due to the type of host tree, the time of the crop and the district, species of lac insect and method of cultivation. Shellac as used by the varnish trade may vary in properties for various reasons, including method of production and time of storage. Production Sticklac.—The incrusted twigs are scraped to remove the lac and this crude product is known as sticklac.

Tall oil (crude tall oil, distilled tall oil, tall oil fatty acids, and rosin acids) is a good source to be turned into polymeric materials. Unlike vegetable oils, tall oil is considered as lignocellulosic plant biomass waste and is considered to be the second-generation raw material, thus it is not competing with the food and feed chain. The main purpose of this review article is to identify in what kind of polymeric materials wood biomass-based fatty acids and rosin acids have been applied and their impact on the properties. Keywords: crude tall oil; tall oil; fatty acids; rosin acids; polymer materials 1. Introduction The success of plastics as a commodity has been significant and polymer materials are a part of everyday life. The advantages of polymers over other materials can be attributed to their adjustable properties, low cost and ease of processing. Worldwide, the manufacturing of polymers grows every year, reaching almost 360 million tonnes in 2018 [1]. In the light of environmental challenges of the 21st century, the development of novel low-cost and scalable monomers from renewable resources is essential.

Based on screening data it is not fulfilling the PBT/vPvB criteria. A test on ready biodegradation is available with tall-oil rosin showing ready biodegradation of the test substance. The P-screening criterion is therefore not fulfilled. Regarding the B-criterion, an experimentally determined log Kow of 3.6 at pH 7 is available. Based on this value a BCF of 56 was calculated with QSAR. The B- screening criterion is therefore not fulfilled. Based on acute aquatic toxicity results with L/EC50 above 100 mg/L the screening T-criterion is not fulfilled. Data on individual constituents are not available. Based on QSAR there is no clear picture regarding persistence, bioaccumulation and toxicity because the constituents have pKa values around environmentally relevant pH values. However, no further testing is considered necessary as tall-oil rosin is readily biodegradable.

  • Rapid Discrimination of Fatty Acid Composition in Fats and Oils by Electrospray Ionization Mass Spectrometry
    ANALYTICAL SCIENCES DECEMBER 2005, VOL. 21 1457 2005 © The Japan Society for Analytical Chemistry Rapid Discrimination of Fatty Acid Composition in Fats and Oils by Electrospray Ionization Mass Spectrometry Shoji KURATA,*† Kazutaka YAMAGUCHI,* and Masatoshi NAGAI** *Criminal Investigation Laboratory, Metropolitan Police Department, 2-1-1, Kasumigaseki, Chiyoda-ku, Tokyo 100–8929, Japan **Graduate School of Bio-Applications and Systems Engineering, Tokyo University of Agriculture and Technology, 2-24-16 Nakamachi, Koganei, Tokyo 184–8588, Japan Fatty acids in 42 types of saponified vegetable and animal oils were analyzed by electrospray ionization mass spectrometry (ESI-MS) for the development of their rapid discrimination. The compositions were compared with those analyzed by gas chromatography–mass spectrometry (GC-MS), a more conventional method used in the discrimination of fats and oils. Fatty acids extracted with 2-propanol were detected as deprotonated molecular ions ([M–H]–) in the ESI-MS spectra of the negative-ion mode. The composition obtained by ESI-MS corresponded to the data of the total ion chromatograms by GC-MS. The ESI-MS analysis discriminated the fats and oils within only one minute after starting the measurement. The detection limit for the analysis was approximately 10–10 g as a sample amount analyzed for one minute. This result showed that the ESI-MS analysis discriminated the fats and oils much more rapidly and sensitively than the GC-MS analysis, which requires several tens of minutes and approximately 10–9 g. Accordingly, the ESI-MS analysis was found to be suitable for a screening procedure for the discrimination of fats and oils.
