🩹 Did you know Elastoplast can cause an allergic reaction?
If you develop a rash, itching or irritation after using certain plasters, colophony (also called rosin) could be the culprit.
Colophony is a natural substance derived from conifer trees and is commonly found in the adhesive used on fabric sticking plasters. It’s one of the most common ways people become sensitised to colophony.
But it can also be found in many everyday products, including:
- Plasters & adhesive tapes
- Cosmetics & nail varnish
- Creams, ointments & some shampoos
- Dental materials
- Paper, magazines & printing inks
- Pine trees, sawdust & pine oil cleaners
- Rosin used for stringed instruments
- Lipsticks, mascara & eyeshadow
- Glues used on stamps & labels
