What Is Quassia Amara Wood?
Quassia Amara Wood comes from the small tropical tree commonly called bitterwood, native to Central and South America. The heartwood is rich in quassinoids such as quassin and neoquassin, natural substances that give the tree its strong bitter taste and are prized for their skin-friendly qualities. Indigenous communities have long used shavings of the wood in tonics and rinses. Modern formulators took note of its soothing properties in the mid-20th century and began including carefully prepared extracts in personal care products.
To obtain the ingredient, sustainably harvested logs are air-dried then milled into chips. These chips are steeped in water or a gentle food-grade solvent to pull out the active compounds. The liquid is filtered, concentrated and either spray-dried into a fine powder or kept as a fluid extract, depending on how the cosmetic chemist plans to use it.
You will most often find Quassia Amara Wood extract in lightweight moisturizers, clarifying masks, after-shave balms and anti-aging serums where a non-oily plant conditioner is desired. It blends easily with water-based gels and lotions, making it a versatile choice for both leave-on and rinse-off formulas.
