Usage: Ascorbyl palmitate is an oil-soluble, powdered antioxidant made with RSPO-SG certified palmitic acid. Ascorbyl palmitate is very color stable and compatible with most cosmetic emollients. Ascorbyl palmitate and tocopherol in the ratio of about 2: 1 mixed is a particularly effective antioxidant for unsaturated fatty acids in oils. Ascorbyl palmitate accelerates the collagen synthesis of the skin and is therefore also suitable for anti-aging products.
