应用
Kojic acid may be used on cut fruits to prevent oxidative browning, in seafood to preserve pink and red colors and in cosmetics to lighten skin. It is used to treat skin diseases like melasma as it has antibacterial and antifungal properties. It is used as a chelation agent that inhibits melanin production and also as a tyrosine kinase inhibitor. 备注
Should be stored at room temperature. Stable under recommended storage conditions. Incompatible with oxidizing agents and bases. 基本信息 MDL

产品说明 应用 曲酸已被用于：
- 作为豚鼠色素性远视 (PH) 中酪氨酸酶的抑制剂
- 作为引用抑制剂标准用于筛选酪氨酸酶抑制
- 作为 B16F10 黑色素瘤细胞中酪氨酸酶抑制的阳性对照
包装 5, 10, 25 g in poly bottle 生化/生理作用 曲酸来源于曲霉菌属、醋酸杆菌属和青霉属等真菌。它通过抑制酪氨酸酶而使黑色素合成停止。用于皮肤美白化妆品的制备。然而，曲酸在化妆品中的使用很少，因为其在长期储存期间的不稳定性和细胞毒性导致皮肤刺激。它是一种抗氧化剂，对锰和锌的螯合起辐射保护作用。

产品说明 一般描述 曲酸是一种酪氨酸酶抑制剂，由多种真菌(包括米曲霉)产生。由于它能够与黑色素形成过程中的含铜酪氨酸酶螯合，因此具有亮肤特性。曲酸也常用作普通化妆品、漂白化妆品等中的增白剂。它是一种治疗剂，有助于防止色素沉着。 应用 有关合适仪器技术的更多信息，请参考产品分析证书。如需进一步支持，请联系技术服务部门。
曲酸可用作分析参考标准品，用于通过高效液相色谱紫外检测(HPLC-UV)测定皮肤增白化妆品和漂泊化妆品中的分析物。 生化/生理作用 酪氨酸酶抑制剂。 基本信息 | 经验(实验)分子式 | C6H6O4 | | 分子量 | 142.11 | | Beilstein | 120895 | | EC 号 | 207-922-4 | | MDL编号 | MFCD00006580 | | PubChem化学物质编号 | 329770427 | | NACRES | NA.24 |
