Frequently Asked Questions
What is ascorbyl palmitate used for?
Ascorbyl palmitate (CAS 137-66-6) is a fat-soluble ester of L-ascorbic acid used as an antioxidant in oils, fats, and food formulations to inhibit oxidation and rancidity. As a fat-soluble vitamin C derivative it is also formulated into cosmetic skin-care products and used for nutritional fortification. RawSource supplies it in bulk to food, supplement, and personal-care manufacturers.
Is ascorbyl palmitate made from palm oil?
Ascorbyl palmitate is the ester of ascorbic acid (vitamin C) and palmitic acid, the C16 fatty acid. Palmitic acid is commonly sourced from palm or other vegetable oils, so the palmitate portion is typically of vegetable origin. Feedstock sourcing varies by supplier; request a specification and origin statement for a given lot.
What is the difference between ascorbyl palmitate and ascorbic acid?
Ascorbic acid is water-soluble vitamin C; ascorbyl palmitate is its fatty-acid ester, which makes it oil/fat-soluble. This solubility difference is why ascorbyl palmitate is selected as an antioxidant in oil and fat systems where ascorbic acid will not disperse. Both share HS classification 2936.27.
What is the HS code for ascorbyl palmitate?
Ascorbyl palmitate is classified under HS 2936.27, covering vitamin C (ascorbic acid) and its derivatives. CAS is 137-66-6 and the molecular formula is C22H38O7. RawSource provides full identity documentation with each bulk order.
How is bulk ascorbyl palmitate packaged and quoted?
RawSource supplies ascorbyl palmitate in bulk industrial quantities for food, supplement, and cosmetic formulators, typically in fiber drums or sacks. Pricing is quote-based and depends on volume, grade, and delivery terms. Submit a bulk RFQ with your target quantity and required specification for current pricing and lead time.
