Vitamin A Palmitate 500 SD CWS/A
Vitamin A Palmitate 500 SD CWS/A is a spray-dried cold-water-soluble powder delivering 500,000 International Units per gram of retinyl palmitate (CAS 79-81-2). The matrix is built on sodium alginate as the primary carrier rather than sucrose, giving a sugar-free composition.
The SD (spray-dried) designation distinguishes the production process from beadlet manufacture. Spray drying gives a more irregular particle shape, often hollow at the centre, and is generally lower in cost per kilogram than equivalent beadlet grades.
We source bulk Vitamin A Palmitate 500 SD CWS/A 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
The grade runs at one nominal potency, 500,000 IU/g, as a free-flowing yellow to amber powder, typically 50 to 500 microns with a broader size distribution than a beadlet grade.
The sugar-free alginate carrier is paired with modified food starch as a co-wall material and a tocopherol or BHT antioxidant package. The dispersion behaviour in cold water is fast and complete, giving a uniformly cloudy yellow solution within seconds.
Bulk density and flow are tuned to suit dry-blending operations, although the irregular spray-dried shape requires somewhat gentler handling than spherical beadlets to avoid breaking the particles.

How We Help Source Vitamin A Palmitate 500 SD CWS/A
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 SD CWS/A 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 SD CWS/A 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 in the United States under 21 CFR 184.1930 and approved as a fortification source in the European Union under Annex I of Regulation 1925/2006.
21 CFR 184.1724 permits sodium alginate as a food additive in the United States, and the European Union permits it as E401. Modified food starch and the antioxidant package follow their respective additive approvals.
USP and Ph. Eur. monographs apply to the vitamin A active content. The matrix is naturally sugar-free, gluten-free, and suitable for vegetarian declarations.
Halal, Kosher, and non-GMO certifications are routinely available, and vegan-suitable variants exist when the antioxidant carrier oil is plant-derived.
Manufacturing Process
Retinyl palmitate concentrate is pre-blended with the antioxidant package, then emulsified into a hot aqueous solution of sodium alginate and modified starch. The emulsion is fed into a co-current or counter-current spray dryer where hot air evaporates the water.
The droplets dry into the characteristic irregular spray-dried particles, often with a hollow or porous internal structure that reflects how fast the water evaporates. The dried powder is recovered in a cyclone or bag filter, screened, and surface-treated with starch or silicon dioxide.
Spray drying is cheaper and faster than beadlet production but typically gives slightly lower oxidative stability because of the higher internal surface area exposed to air. Producers compensate by raising the antioxidant load and by packaging under nitrogen.
