CAS No. 220644-17-7

Aminopropyl Ascorbyl Phosphate (AAP) is a water soluble derivative of Vitamin C created by combining l-ascorbic acid with 3-APPA (3-aminopropyl dehydrogen phosphate), a molecule that boosts the stability of the l-ascorbic acid.

Vitamin C is a potent, naturally occurring antioxidant which plays a pivotal role in the prevention of dry skin and wrinkles, collagen synthesis and skin regeneration, as well as skin lightening and brightening, but it is inherently unstable in water.
