Diospyros Kaki Fruit Extract

Diospyros Kaki (persimmon) fruit extract is used mainly as an antioxidant/astringent botanical in low percentages, but plant extracts contain multiple bioactive compounds (including tannins and polyphenols) that can sting or provoke irritation on compromised barriers. Clinical patch-test data for this specific extract is limited compared with well-characterized actives, so for eczema-prone and highly reactive patients I treat it as a mild irritant with occasional sensitivity potential, especially when combined with other actives or in leave-on formulas. Safety Notes: In mass-market leave-on skincare (toners, lotions, creams) Diospyros Kaki Fruit Extract is typically used at very low label-support levels (~0.001–0.1%) as part of a broader botanical blend, and in rinse-off cleansers it is often similarly low due to cost and wash-off exposure. Higher-strength consumer products marketed for deodorizing/anti-odor or antioxidant benefits (e.g., specialty serums, concentrates, and some mask/essence formats, often using standardized or glycerin/propylene glycol extracts) can reach ~1–5%, with >5% being uncommon in OTC products due to odor/color impact and formula stability/compatibility constraints.
