Uses
Fat-soluble antioxidant: L-ascorbyl palmitate is a fat-soluble antioxidant that can clear lipid peroxides in the body, preventing oxidative damage to cell membranes, fats, and cholesterol by free radicals. Therefore, it can be used to prevent and slow down aging and the development of diseases.
Health supplement material: L-ascorbyl palmitate is widely used as a material for health supplements because it can improve immunity, improve skin quality, and reduce blood lipids and blood sugar.
Cosmetic material: L-ascorbyl palmitate is widely used in cosmetics, especially in anti-aging and whitening products, due to its antioxidant and whitening effects.
Pharmaceutical adjuvant: Studies have shown that L-ascorbyl palmitate can be used as an adjuvant drug to kill Helicobacter pylori. H. pylori is a pathogenic bacterium that causes gastric ulcers and gastric cancer. L-ascorbyl palmitate can prevent the growth and reproduction of H. pylori by lowering the pH value of gastric juice.
