制备方法与用途

熊果苷:美白化妆品的理想增白剂 什么是熊果苷

熊果苷是一种天然绿色植物提取的成分,又称熊果甙熊果素、熊果叶甙或杨梅甙。它具有“绿色”、“安全”和“高效”的特点,是理想的皮肤美白活性物质。熊果苷有两种旋光异构体——α型及β型,其中β型具有生物活力。

熊果苷的特性
  • 室温下为白色略带淡黄色粉末,易溶于甲醇乙醇丙二醇等。
  • 在许多美白保养品中都有添加。
  • 由于从杜鹃花科熊果属植物熊果叶中被发现而得名。此外,它还在杜鹃花科越桔属植物越桔、蔷薇科梨属植物沙梨树(包括西洋梨和小山梨)、虎耳草科虎耳草属植物虎耳草等的叶子中被发现。
  • 它具有镇静、抗炎、抗菌等多种生物学效应,近年来还发现它有抗癌作用。
熊果苷在化妆品中的应用

熊果苷是目前国外流行的最安全有效的美白原料之一。其作用原理类似于美白药物对苯二酚,但刺激性较低,可以自由添加到保养品中,浓度上限高达7%。它能高效美白祛斑,淡化雀斑、黄褐斑、黑色素沉着等。

α-熊果苷

α-熊果苷具有修复肌肤因紫外线引起的损伤的作用,并且不易被皮肤表面的β-葡萄糖苷酶分解,效果约为β-熊果苷的10倍。它能在皮肤表层形成双重效果,抑制黑色素生成。

熊果苷的安全性与适用时间

熊果苷的活性分子能够穿透基底层进行深度淡斑,适用于黄褐斑、黑斑和日晒斑等。5%浓度是最安全和最高效的淡斑浓度。虽然熊果苷被皮肤吸收后会还原成对苯二酚,但添加在保养品中的熊果苷浓度低于7%,不会产生光敏性。

化学性质与用途

总之,选择可靠的保养品并在白天做好防晒是关键。
