Citrus Unshiu Peel Extract
Citrus Unshiu Peel Extract is derived from the peel of Citrus unshiu (Satsuma mandarin/tangerine), a seedless variety originating from the Japanese town of Satsuma. It is primarily produced from the "press-cake" by-product of the juice industry. Its CAS number is 98106-71-9 and EC number is 308-594-6. The official CosIng function listed is masking.
The extract is primarily used as a skin-brightening or whitening agent, with in-vitro and animal studies showing promising results for inhibiting tyrosinase, the enzyme that regulates melanin production. It also contains antioxidant components — including carotenoids, coumarins, limonoids, and flavonoids — that may help protect the skin from UV-induced damage.
Citrus peel extracts typically contain some amount of essential oil components, which may be a concern for individuals with very sensitive skin or known sensitivities to citrus-derived ingredients.
