Epoxy resin
Epoxy resin is the diglycidylether of bisphenol-A and is found in strong, two-part plastic adhesives. Only the resin - the uncured epoxy - is sensitizing, and the 340 monomer the essential sensitizer.Quinoline mix
Quinoline mix contains clioquinol and chloroquinadol, two antimicrobials used in medicated creams and ointments for wound infections and infected eczemas. Quinolines are not uncommon sensitizers in countries where they are used.Balsam of Pew
Balsam of Peru is a wood extract from the South American tree Myroxylon pedere. In the past, it was commonly incorporated as fragrance in cosmetics, medical creams and ointments and used as flavouring in teas, tobaccos, cough syrups, colas, ice creams, baked goods and many other foods. It is decreasingly used, but gives a good indication of fragrance sensitivity, as it includes several different fragrances that sensitize, such as benzyl cinnamate, benzylbenzoate, cinnamic aldehyde and isoeugenol.Ethylenediamine dihydrochloride
Ethylenediarnine is an emulsifier and stabilizer found in both medicated and non-medicated topical preparations such as creams and nose drops. It is used industrially as a solvent, curing and anticorrosive agent.Cobalt chloride
Metallic cobalt and cobalt salts are strong sensitizers, and are found in many metal plated objects including buckles, buttons and zips, but also in artists' paints, wet cement and hard metal. Cobalt is often found together with nickel, and allergy occurs to both these metals in 25% of nickel sensitivity. This is not regarded as true cross sensitivity.p-tert-butylphenol formaldehyde resin
p-tert-butylphenol formaldehyde resin is a condensation product of formaldehyde and p-tert-butylphenol. It is a source material for many waterproof glues and finishes, and is frequently used in the construction and shoe industries. It is found in leather goods, furniture, rockwool, hard board, high quality paper and glossy fabrics. Phenolformaldehyde resins are a group of more or less condensed substances. Many of them sensitize. P-tert-butylphenol formaldehyde resin indicates most of this sensitivity.Paraben mix
The mixture contains five different parabens; methyl-, ethyl-, propyl-, butyl- and benzyl-parahydroxybenzoate. Parabens are the most used topical preservatives worldwide. Parabens are found in several medical creams, lotions, pastes, and in several cosmetics and skin care products. Parabens are used as food preservatives and industrially in oils, fats and glues. Sensitivity to parabens is not uncommon although rare in relation to their widespread usage. Parabens are lipophilic and have low irritant and sensitizing potential.(published with permission in writing from:http://www.lactose.co.uk)
