Ascorbyl tetraisopalmitate, as a vitamin C derivative, penetrates into the skin and transforms into vitamin C and then plays the role of vitamin C (hence it is also called a vitamin C derivative). It is a colorless to light yellow liquid with good oil solubility and can be widely and quickly dissolved in esters, vegetable oils, ethanol and hydrocarbons (except polyols). At the same time, ascorbyl tetraisopalmitate is mild and non-irritating, so it can be used for sensitive skin.
Ascorbyl tetraisopalmitate esterifies hydroxyl groups based on the molecular structure of vitamin C (as shown in the figure below). It is the most stable of all vitamin C derivatives. It is very stable under air and light, even if heated at high temperatures. Can maintain stability.
Due to its good oil solubility and similar compatibility with skin lipids, ascorbyl tetraisopalmitate has excellent transdermal absorption rate. Its absorption rate in the epidermis can reach more than 20% and 1% in the dermis. The absorption capacity of 2% is 3 times that of L-vitamin C.
