Occupational asthma due to
colophony in a violin player.
It is also referred to as Greek pitch or
colophony. Gum Rosin is a semi-transparent material and is available in different types and different colours.
10,166,178 B2 (Raul Vidal Esmoris, Gema Garcia De Miguel); Grupo DRV Phytolab, S.L., a Spanish firm, has patented a depilatory composition consisting of synthetic resins selected from the group consisting of petroleum resin and
colophony resin; a carrier of a hydrophilic cosmetic active agent.
The most common allergens giving positive patch test were PPD in 54 (68.4%), fragrance mix in 8 (10.1%),
colophony, parabens mix and thiomersal in 3 each (3.8%) and formaldehyde in 2 (2.5%) patients (Table 6).
The resin is composed of a solid fraction, called a pitch or gum
colophony, and a volatile part, known as turpentine.
The reference compounds belong to the classes of polysaccharide (cellulose 63600; Arabic gum 63300), lipid (carnauba wax 62300; beeswax 62200; shellac wax 60550), proteinaceous (hide glue 63020; bone glue 63000; casein 63200) and natural resinous (sandarac 60100; manila copal 60150;
colophony 60310; Venetian turpentine 62010; dammar 60001; mastic 60050; shellac 60480; dragon's blood 37000) materials.
Milk or casein, animal glue, egg, drying oils (walnut, linseed, and poppy seed oils), plant resins (e.g., sandarac, mastic, and
colophony), animal resins, and waxes are the most common organic materials historically used in the Mediterranean area and in Europe.
In electronic industry the workers are exposed to solder fumes containing
colophony cause severe asthma problems [1] and it also cause lungs cancer and occupational asthma [2].
Exclusion criteria for FV application include children with a history of an allergy to
colophony and children diagnosed with asthma who do not have their rescue medication, for example, a short-acting bronchodilator, at time of application.
