Players ofbowed string instruments(violin,viola,cello,double bass) rub cakes or blocks of rosin on theirbowso it can grip the strings.Balletandflamencodancers sometimes rub their shoes in powdered rosin to reduce slippage before going on stage.Gymnasts,baseballpitchersandten pin bowlersuse rosin to improve grip. Common locations of thiscontact dermatitisarehands,faceandneck.[2]: 1374
It has also occurred as a result ofdehydroabietic acidin an over-the-counter hydrocolloid dressing.[3]
