Castanea Sativa (Chestnut) Seed Extract
What is Castanea Sativa (Chestnut) Seed Extract?
Castanea Sativa (Chestnut) Seed Extract comes from the seeds of the sweet chestnut tree, a species native to temperate regions of the Northern Hemisphere. This plant-derived ingredient is produced via water or solvent extraction to isolate key compounds such as tannins, flavonoids, and phenolic acids. In cosmetic formulations, it serves as a conditioning agent in skincare and haircare products like creams, lotions, shampoos, and serums. Its primary functions include delivering astringent properties that firm the skin's surface, antioxidant activity to shield against oxidative stress, and emollient effects that soften and protect hair shafts and cuticles. These actions stem from its rich polyphenolic profile, making it suitable for rinse-off and leave-on applications where gentle botanical support is desired.
