Vitamin A Palmitate 500 DC
Vitamin A Palmitate 500 DC is a high-potency direct-compression grade delivering 500,000 International Units per gram of retinyl palmitate (CAS 79-81-2). The DC designation indicates that the powder is granulated to flow through high-speed tablet presses without prior wet granulation.
The grade exists to solve a practical manufacturing problem: vitamin A oil cannot be pressed into tablets directly, and standard CWS beadlets do not always survive the compression forces of a rotary tablet press. The DC format is engineered to compact cleanly while protecting the active.
We source bulk Vitamin A Palmitate 500 DC from top China manufacturers for our partners. The manufacturer is in Zhejiang. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
One potency only, 500,000 IU/g nominal, in a free-flowing granulate typically 100 to 600 microns with a tight particle size distribution.
The carrier is built around microcrystalline cellulose, pre-gelatinised starch, or gum acacia, chosen for their compressibility and ability to deform plastically rather than fracture under tabletting pressure. Modified food starch wraps the vitamin A oil core, and a tocopherol or BHT antioxidant package protects against oxidation.
Bulk density is tuned to match standard tablet-press hopper behaviour, and the granulate is dusted with a flow aid to maintain uniform die filling at high press speeds.

China Manufacturers of Vitamin A Palmitate 500 DC
Top Vitamin A Palmitate 500 DC manufacturers in China.

How We Help Source Vitamin A Palmitate 500 DC
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Vitamin A Palmitate 500 DC out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Vitamin A Palmitate 500 DC together with other ingredients such as Vitamin C, Vitamin D3 and Vitamin E into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
The vitamin A active is retinyl palmitate, GRAS under 21 CFR 184.1930 in the United States and listed as a fortification source under Annex I of EU Regulation 1925/2006.
Microcrystalline cellulose, pre-gelatinised starch, gum acacia, and modified starch are all conventional food-grade excipients with global pharmacopoeial monographs in USP-NF and Ph. Eur. Silicon dioxide and talc as flow aids are approved under their respective additive regulations.
The tocopherol or BHT antioxidant package follows the same approvals as in beadlet grades. The vitamin A active content is assayed against USP and Ph. Eur. monographs by HPLC.
Tablet-grade purity, microbiological limits, and heavy-metal specifications meet USP <2232> and Ph. Eur. 5.1.4 expectations. Halal and Kosher certifications exist from most producers.
Manufacturing Process
Production begins with vitamin A palmitate concentrate emulsified into a hot aqueous binder solution containing modified starch and the chosen antioxidant package. The emulsion is sprayed onto a fluidised bed of carrier particles such as microcrystalline cellulose or pre-gelatinised starch.
The wet granulate is dried in the same fluid-bed unit, screened to remove fines and oversize, and surface-treated with a flow aid such as silicon dioxide or talc. Particle shape and bulk density are tuned during granulation to match high-speed rotary press requirements.
Compression studies confirm that the granulate survives typical tableting forces (10 to 30 kN main compression) without significant vitamin A loss. Tablets produced from the DC grade routinely retain 90 percent or more of label potency through a 24 month shelf life when packed in HDPE bottles with desiccant.
