About
An Amazonian resin (Breu branco) from Protium heptaphyllum — traditional use, terpene-rich, sensitization-possible for some users.
Protium heptaphyllum resin (CAS 92704-59-1) is a fragrant natural resin known in Brazil as Breu branco, harvested from trees of the Burseraceae family. It contains triterpenoids, monoterpenes, and sesquiterpenes giving a balsamic aroma. In cosmetics it functions as a fragrance/film-forming/thickening natural. Modern SCCS/CIR data is thin — mostly ethnobotanical documentation. Terpene-rich resins are structurally prone to causing contact sensitization in some users, especially oxidized material. No CMR classifications. Score sits at mid Fine tier reflecting long traditional use combined with thin independent safety/efficacy literature.
