Sodium Ascorbyl Palmitate
What is Sodium Ascorbyl Palmitate?
Sodium Ascorbyl Palmitate is a synthetic compound formed by esterifying ascorbic acid, the active form of vitamin C, with palmitic acid, a saturated fatty acid from natural sources like palm and coconut oils. As the sodium salt of this ester, it exhibits enhanced oil solubility and stability compared to water-soluble ascorbic acid. In cosmetic products such as creams, lotions, serums, and lip products, it primarily functions as an antioxidant, scavenging free radicals to prevent ingredient degradation from oxygen, light, and heat exposure. It also works as a skin-conditioning emollient, aiding in product texture and spreadability. Its lipophilic properties make it ideal for oil-in-water emulsions and anhydrous formulas, where it integrates seamlessly to maintain formulation integrity without compromising stability over time.
Benefits
Supports formulation stability by acting as an antioxidant against oxidation.
