Balsam Peru Resin

What is Balsam Peru Resin?

Balsam Peru resin, derived from incisions in the bark of the Myroxylon balsamum tree native to Central America, is a sticky, aromatic oleoresin with a rich, sweet, vanilla-like and balsamic scent profile. Chemically, it contains compounds like cinnamic acid, benzoic acid, and vanillin derivatives. In cosmetics, it appears mainly in fragrances, hair care, and personal care products. It functions by imparting lasting scent notes, stabilizing volatile aromas as a fixative, covering undesirable base odors, enhancing hair smoothness through conditioning effects, and creating a subtle protective film on hair shafts or skin for improved product adherence and sensory feel.
