Bacitracin zinc is an effective narrow-spectrum antibiotic peptide with a similar antibacterial spectrum to penicillin, mainly for Gram-positive cocci and bacilli.

It is a white or off-white powder with a characteristic odor and bitter taste, a mixture of related cyclic peptides produced by organisms of the licheniformis group of Bacillus subtilis var Tracy.

These peptides disrupt Gram-positive bacteria by interfering with the cell wall and peptidoglycan synthesis.

Zinc bacitracin is one of our USFDA-Approved pharmaceutical ingredients along with Bacitracin Powder and polymyxin b sulfate Powder.

Those 3 ingredients are often mixed to be produced into ointments, sprays, etc, to avoid infections of the small cuts.

Bacitracin zinc also exerts a certain inhibitory effect on several Gram-negative bacteria, spirochetes, and actinomycetes with high efficiency, low toxicity, and low residue.

First thing first, we must mention upfront, there are two types of powders:

1. high-potency type Pharm-Grade (Potency No Less Than 65IU/MG);

2. Feed-Grade or Industrial-Grade (Potency Less than 40IU/MG, often made into premixes).

Here we only supply pharmaceutical-grade types which are used to manufacture medicines for humans.
