What it is
Cupuacu seed butter is a soft, solid fat obtained from the seeds of Theobroma grandiflorum, a relative of the cacao tree. It is valued in cosmetics for its emollient feel and high content of fatty acids and phytosterols, which help soften skin and improve the texture of balms, sticks, and creams. In sun care it contributes a cushioned, conditioning skin feel.
Safety & warnings
Generally well tolerated and suitable for most skin types. Like other rich plant butters it is occlusive and may feel heavy on very oily or acne-prone skin, where it could contribute to congestion in susceptible individuals. It is not a recognized fragrance allergen.
Origin & sourcing
Plant-derived, cold-pressed or expeller-pressed from the seeds of the cupuacu tree native to the Amazon basin in Brazil and surrounding regions.
History
Cupuacu is a long-standing food and traditional ingredient in the Amazon; its seed butter gained popularity as a cosmetic emollient in the 2000s as an alternative to cocoa and shea butters.
