    • The alpha-lipoic acid-containing ascorbic acid derivative is provided to increase the stability, especially in the aqueous media of ascorbic acid and alpha-lipoic acid, thereby mininizing the denaturation by environments including temperature, light, oxygen and water when it is stored in the aqeous composition for a long time. The alpha-lipoic acid-containing ascorbic acid derivative having improved stability is represented by the chemical formula(1), wherein two of R1 to R4 are hydrogen, one of the remaining radicals is alpha-lipoyl, and the remaining radical is C1-C4 alkyl, CH3CH2O-(CH2CH2O)m-CH2CH2- (M is an integer from 7 to 45), glucosylor C8-C18 acyl.
    • 提供含有α-硫辛酸的抗坏血酸衍生物,以提高稳定性,特别是在抗坏血酸和α-硫辛酸的水性介质中,从而通过温度,光照,氧气和水的环境使其变性在存储时变得容易。 长时间的组成。 具有改善的稳定性的含α-硫辛酸的抗坏血酸衍生物由化学式(1)表示,其中R 1至R 4中的两个为氢,剩余基团之一为α-脂酰基,剩余的基团为C 1 -C 4 烷基,CH 3 CH 2 O-(CH 2 CH 2 O)m -CH 2 CH 2 - (M为7至45的整数),葡糖基-C 8 -C 18酰基。
