Glycolic acid
Glycolic acid is a well-known organic acid with a range of important applications across various industries. Its discovery and multiple uses make it a key compound in the industrial and cosmetic fields.
乙醇酸 （C₂H₄O₃） 于 1832 年由法国化学家 Henri Braconnot 首次分离出来。他从甘蔗中提取它，后来又从未成熟的葡萄中提取它。该化合物是一种无色无臭的液体，略带酸味。它的发现对 α-羟基酸 （AHA） 的研究至关重要，AHA 在许多化学和生物过程中起着重要作用。
乙醇酸是最小的 α-羟基酸，极易溶于水。它的熔点为 76°C，pKa 为 3.83，与其他 AHA 相比，它是一种相对较强的酸。它的小分子尺寸使其能够有效地渗透皮肤，这对于其在化妆品配方中的使用至关重要。
乙醇酸因其去角质特性而广泛用于化妆品中。它是化学换肤和面部护理的关键成分，有助于去除死皮细胞，改善皮肤质地，减少细纹和皱纹 的出现。它刺激胶原蛋白产生的能力也有助于使皮肤看起来更年轻。
