About

A sticky pine resin material that helps with film and grip, but it is a well-known contact allergen.

This ingredient is a pine resin used for binding, tack, and film formation. Rosin and related resin acids are classic contact allergens, so this is one of the riskier resin-type cosmetic ingredients for sensitized users.
