1. Differences In Molecular Structure:
VC ethyl ether: VC ethyl ether is a fat-soluble derivative of vitamin C. Its molecular structure has been modified to make it more stable. This improved structure helps improve the stability of VC ethyl ether in cosmetics, making it easier to be absorbed by the skin.
L-Ascorbic Acid: L-ascorbic acid is a natural form of vitamin C, but it is highly unstable and is easily affected by light, air and temperature and loses activity. This requires more complex formulations and storage conditions when used in cosmetics.
2. Stability And Storage Performance:
VC ethyl ether: VC ethyl ether is more stable than L-ascorbic acid due to its fat-soluble properties. This means that VC ethyl ether has a longer shelf life in cosmetics and is less susceptible to the impact of the external environment.
L-Ascorbic Acid: The instability of L-ascorbic acid causes it to be easily oxidized, and once oxidized, it will lose its activity. Therefore, skin care products containing L-ascorbic acid may require higher storage requirements and shorter use cycles.
3. Absorption Performance:
L-Ascorbic Acid: L-ascorbic acid is relatively water-soluble and has poor absorption properties. In some cases, high concentrations of L-ascorbic acid may be required to achieve certain effects, but high concentrations also bring discomfort during use.
4. Applicable Skin Types And Problems:
VC Ethyl Ether: Due to its relatively mild nature, VC Ethyl Ether is suitable for all skin types, including sensitive skin. It has good performance in whitening, antioxidant and anti-aging.
L-Ascorbic Acid: L-ascorbic acid may be irritating to sensitive skin, especially in high concentrations. It is more commonly used to combat skin aging, pigmentation, and other issues.
5. Usage Environment And Conditions:
L-Ascorbic Acid: L-ascorbic acid requires more stringent storage conditions in some cases to maintain its activity. Light, air and high temperatures may affect its stability.
6. Cost factors:
VC ethyl ether: Due to its relatively stable nature and longer shelf life, VC ethyl ether is relatively low-cost to produce and use.
L-Ascorbic Acid: The instability of L-ascorbic acid may lead to more frequent product updates and higher production costs.
