COSROMA makes their documentation available in the regions indicated below:

3-O-Ethyl Ascorbic Acid is commonly known as Ethyl Ascorbic Acid. 3-O-Ethyl Ascorbic Acid offered by COSROMA is called Cosroma® EAA. Cosroma® EAA is 99.5% 3-O-Ethyl Ascorbic Acid. 3-O-Ethyl Ascorbic Acid is a stable Vitamin C derivative with excellent skin brightening activity. 3-O-Ethyl Ascorbic Acid’s chemical structure is unique in that the ethyl group forms an ether with the 3-hydroxy group of the ascorbic acid, which results in much higher stability. Other commercialized ascorbic acid derivatives are ethers at the 2-hydroxy position. 3-O-Ethyl Ascorbic Acid is a powerful inhibitor of melanogenesis. In contrast to ascorbyl glucoside or magnesium ascorbyl phosphate, which must undergo cleavage by hydrolytic enzymes for activity, 3-O-Ethyl Ascorbic Acid acts directly. Therefore, 3-O-Ethyl Ascorbic Acid is faster-acting than these materials and also shows a longer-term inhibitory effect.
