Neomycin Sulfate Powder

Neomycin Sulfate Powder | Broad-Spectrum Antibiotic API for Veterinary & Pharma Use

Neomycin Sulfate Powder from Shaanxi Hongda Phytochemistry Co., Ltd. is pharmaceutical-grade and comes from fermenting Streptomyces fradiae. It is 99% pure and has a potency of 600 µg/mg (anhydrous basis). Each batch meets USP/CVP standards and has certificates from cGMP, FDA, ISO9001, Halal, Kosher, and BRC. It is made in a 100,000-level processing workshop spread out over 20,000 m² of modern facilities. Hongda is a reliable source of APIs for formulators of animal medicines, pharmaceuticals, and topical products in Europe, North America, and Asia. They can produce up to 3,000 tonnes of APIs each year and send them in 3–7 business days.

Product Introduction

Neomycin Sulfate Powder is an aminoglycoside antibiotic that is used mostly in animal medicine and making medicines for people. It kills bacteria by attaching itself permanently to the 30S ribosomal subunit of bacteria. This causes the genetic code to be misread and stops protein synthesis.

The chemical mostly works on aerobic Gram-negative bacteria like E. coli, Salmonella, and Klebsiella. It can also kill Gram-positive strains like Staphylococcus aureus. It gathers in the gut because it is not well absorbed from the digestive system. This makes it the best choice for sterilising the intestines and treating enteric infections.

Workshop Production Line

Third-Party Test Report

Before it is shipped, every production batch goes through several stages of quality checks. Our SGS-standard laboratory tests our products for heavy metals, moisture, microbial load, and effectiveness (using Staphylococcus epidermidis for a microbiological study). It also does HPLC-based impurity monitoring (Neamine, Neomycin A, and Neomycin C ratio).

We also work with outside companies like SGS and Eurofins to do testing for pesticide residue, measuring optical rotation, and nutritional labelling. The amount of Neomycin C is carefully kept within the EP/USP range of 3% to 15%; any change above or below this range means the fermentation quality is bad and the drug's effectiveness is lower.

All test documents can be sent upon request before the sale is confirmed.

Certificate of Analysis (COA)

For each batch, a full COA is given out, which includes:

·Smell, look, particle size, and mass density

Test for potency (µg/mg, anhydrous basis)

Value for optical rotation

Information on pH and solubility

Heavy metals (Pb, As, Cd, Hg)

Lost when it dries out and sulfated ash forms

Counts of microbes and lack of pathogens

Checking for sulphate content

By batch number, COA documents can be tracked. Before you place a large order, you can ask for a sample COA.

Neomycin Sulfate Powder Advantages

Stable Across pH and Temperature

It works against microbes best at pH 7.0–8.0 and stays active between 2.0 and 9.0. It doesn't break down in alkaline conditions like tetracyclines do, which makes it more reliable in systems that provide medicated drinking water.

High Solubility in Water

With a water solubility of about 6.3 mg/mL, it dissolves easily and can be used to make soluble powders or to give animals drinking water.

Hard to break down by enzymes

Many bacterial enzymes can't break down its chemical structure, so it stays active in the complex gut microbial environment. This is especially important for uses related to the health of chickens and pigs' guts.

Neomycin C Ratio Is Controlled

Hongda keeps a close eye on the fermentation process to make sure that Neomycin C stays between 3% and 15%. This keeps the drug's strength stable and lowers the risk of toxicity from inactive isomers.

Neomycin Sulfate Powder Application

1. Veterinary Soluble Powders

Often used to treat bacterial enteritis in pigs and chickens that are raised in large farms. It works well in hard water and can be used with treatments that recover lost fluids. Usually made as a premix or a liquid powder that can be used to treat the whole herd.

2. Topical Formulations for People

Provided as a base for creams, ointments, and eye drops, most of the time with Polymyxin B and Bacitracin. Because it doesn't absorb well through healthy skin, it can be used safely on small wounds and burns.

3. Speciality drugs for pre-surgery and liver use

Oral versions are used in clinical settings to get rid of bacteria in the gut that make ammonia in people with hepatic encephalopathy and to clean the intestines before colon surgery.

Production Process

Hongda's production uses an extraction method based on fermentation:

The steps are: fermentation; extraction and filtration; purification (ion exchange); crystallisation; drying; milling; quality control testing; and Packaging.

The 100,000-level cleaning workshop keeps particles from getting into the process as it's going on. During drying, moisture is carefully controlled to keep LOD ≤8.0%. This stops the hygroscopic caking that usually happens with this type of powder. From the raw fermentation culture to the final drum packaging, each batch can be tracked.

OEM / ODM Support

Hongda offers customised production to meet your recipe needs:

Choose your own particle size and mesh fineness

Premix mixing with API combinations that work well together (for example, Oxytetracycline and Polymyxin B)

On private label packaging, you can put your name, image, and legal text.

Small test batches are available for research and development (R&D) or testing before going on the market.

Types of formulations: liquid powder, premix, capsule fill, pill blend

Your product specifications are handled in a clean, germ-free space, and all of your paperwork is taken care of, including the COA, MSDS, specification sheet, and regulatory dossier.

FAQ

Q1: What is the usual level of strength for USP-grade material?

A: The potency must be at least 600 µg/mg when the substance is not mixed with water. A microbiological test showed that Hongda's standard batch results usually go above this level.

Q2: How should the product be kept so that it doesn't break down?

A: Keep it in plastic or glass containers with tight lids that don't contain sodium at temperatures below 30°C. If you don't seal the powder, it will take moisture from the air, which will cause it to clump and lose its effectiveness.

Q3: Can it be mixed with other medicines to make a premix?

A: Yes, it works better when combined with Oxytetracycline and Polymyxin B. But don't mix it with anionic substances like some vitamins or detergents, because precipitation could happen.

Q4: Does the pH of the water in the lines change how well it kills bacteria?

A: Yes, Neomycin works best in places with a pH of 7.0 to 8.0. If you are acidifying your water lines for sanitation reasons, stop the acidification while you are on medication to get the full antibacterial effect.

Q5: What are the exit times for producing meat from animals?

A: Standard removal times for edible tissue (mostly kidney and liver) are between 5 and 14 days, but this depends on the dose and local rules like FDA or EMA standards. Always check with the local government.

Q6: Can this grade be used to make liquid products?

A: Standard oral and dermal grades are not germ-free. To make injectables, you need a special kind of sterile material that meets tighter rules for endotoxin and particulate matter. Get in touch with us to talk about sterile-grade availability.
