L Serine Powder Specification

Third-Party Test Report

Every batch of our L-serine is tested by SGS and Eurofins, among other approved third-party laboratories, as well as internally. Coverage for testing:

L-form stereochemical integrity and ≥99% purity are confirmed by the HPLC assay.

Lead, arsenic, cadmium, and mercury screens are part of ICP-MS heavy metal testing.

Microbiological testing: yeast, mould, and total plate count

Screening for pesticide residues

The polarimeter measures the specific optical rotation, which ranges from +14.0° to +15.6°.

Ash content and drying loss

Each shipment comes with batch-specific COAs and test results. At any point during the sourcing process, you can ask for test documentation.

COA (Certificate of Analysis)

Our COA for each batch includes the following verified data points:

COA documents are batch-traceable and available upon request before and after order placement.

L-Serine Powder Bulk Advantages

What distinguishes our L Serine Powder Bulk from other products on the market?

high purity of stereoisomers.Our fermentation method yields L-form serine with little D-isomer contamination, which is essential for the synthesis of APIs and the production of peptide drugs.

low moisture content (less than 0.2%).This prolongs shelf stability even in humidity-sensitive manufacturing settings and avoids clumping during high-speed industrial blending.

outstanding flowability.Smooth, automated encapsulation without equipment obstruction or weight variation problems is supported by a uniform particle size distribution.

origin that is vegan and non-animal.produced by microbial fermentation with non-GMO glucose substrates; appropriate for final goods certified as VEGAN, KOSHER, and HALAL.

complete regulatory records.Every order includes copies of the COA, MSDS, test results, and certificates to assist your regulatory submissions in the US, EU, and other markets.

L-Serine Powder Bulk Application

L-serine is used in a variety of sectors and product categories.

pharmaceutical intermediates.It serves as the precursor to L-serine methyl ester hydrochloride and cycloserine production. High purity increases yield in the synthesis of peptide drugs and avoids adverse reactions in the manufacturing of third-generation cephalosporins.

vitamins for brain health.Phosphatidylserine (PS), a phospholipid frequently utilised in formulations for cortisol management and cognitive support, is made from L-serine, an enzyme substrate. In enzymatic bioreactors, uniform particle size guaranties ideal dissolving rates.

formulas for skincare and cosmetics.High-end lotions and serums contain L-serine, which is a part of the skin's Natural Moisturising Factor (NMF). It supports stratum corneum moisture retention without having a sticky texture and preserves emulsion stability across a wide pH range.

mixes of amino acids and sports nutrition.It is simple to add to functional drinks and ready-to-mix powders because to its water solubility (~250 g/L at 20°C).

Production Process

Shaanxi Hongda uses a regulated microbial fermentation technique to create L-serine:

1. Selection of raw materials: non-GMO glucose substrates, confirmed for quality and origin

2. Fermentation: Optimising L-isomer production using regulated bioreactor conditions

3. Extraction and purification: Purification in multiple stages to achieve an assay of at least 99%

4. Drying: Use a low temperature to maintain moisture levels below 0.2%.

5. Milling and sieving: regulated particle size for solubility and flowability

6. Quality control: Complete HPLC, microbiological, and heavy metal testing

7. Packaging: 12 kg per barrel of fibre drums with double-lined PE inner bags

Production is carried out under cGMP conditions in 100,000-class cleanroom workshops with complete batch traceability from raw material to final product.

FAQ

Q1: How pure is your L-serine powder?

A: According to USP, AJI, FCC, and EP standards, our L-serine assay is ≥99% by HPLC. Every batch comes with a complete COA.

Q2: Can vegan and halal-certified products use your L-serine?

A: Indeed. It is made by microbial fermentation with non-GMO glucose and no inputs obtained from animals. It is certified KOSHER and HALAL, and it can be used in recipes with the VEGAN label.

Q3: What is the best way to store bulk L-serine powder?

A: Store below 25°C and 60% relative humidity in a cool, dry place. Because L-serine is naturally hygroscopic, double-lined PE bags prevent moisture absorption.

Q4: Are third-party test reports available for every batch?

A: Indeed. We collaborate with SGS and Eurofins to independently verify pesticide residues, heavy metals, and nutritional labelling, and each shipment contains batch-specific COA data.

Q5: What is the lead time and minimum order quantity?

A: Stocked items typically arrive within 3–7 working days. For a formal quote, get in touch with us. MOQ and pricing are dependent on quantity.

Q6: Does manufacturing performance depend on particle size?

A: It does. Although finer mesh sizes increase blending uniformity and solubility, handling must be done under humidity control to avoid caking. Depending on your processing equipment and application requirements, we can modify the mesh size.
