What it is
Myristyl 3-Glyceryl Ascorbate is a derivative of ascorbic acid (vitamin C) in which the molecule is modified with glyceryl and myristyl groups to improve stability and oil compatibility relative to pure vitamin C. The fatty myristyl chain gives it lipophilic character, helping it disperse in the oil phase of emulsions. It is used in brightening-oriented day essences and sunscreens as an antioxidant skin-conditioning agent.
Safety & warnings
Stabilized vitamin C derivatives of this type are generally well tolerated and tend to be less irritating than free ascorbic acid because they avoid the high acidity associated with the parent molecule.
Origin & sourcing
Synthetic; a chemically modified derivative of L-ascorbic acid.
Questions everyone asks
Is Myristyl 3-Glyceryl Ascorbate a form of vitamin C?
Yes, it is a stabilized derivative of ascorbic acid modified to be more stable and oil-compatible than pure vitamin C.
Why use a vitamin C derivative instead of pure vitamin C?
Derivatives like this improve formulation stability and oil dispersibility and are often gentler than the highly acidic free acid.
