BND-10 Preservative

BND-10 Preservative is a broad-spectrum, efficient, stable, and low-toxicity preservative commonly used in in vitro diagnostic reagents and similar applications.

This preservative effectively inhibits the growth of microorganisms such as bacteria and fungi over extended periods, with particularly strong efficacy against Gram-negative bacteria and very low risk of resistance. The product is a colorless or pale yellow transparent liquid with a characteristic bromine-like odor. Its main component is a 10% solution of bronopol in propylene glycol, and its dual-mode mechanism of action effectively inhibits microbial growth, leading to cell death.

BND-10 is compatible with antibodies and various enzymes, also functions as a surfactant, is easy to rinse off, and contains no secondary amines. It provides excellent preservative effects even in formulations with low protein content, without affecting the activity of common enzymes or antibody binding reactions. It is suitable for a wide range of biochemical and immunological detection reagents.

This product is highly effective, stable, low in toxicity, and environmentally friendly. It acts rapidly, works over a broad pH range (pH 5–8.5), and has good chemical stability. It mixes easily with water, and at diluted concentrations, it is minimally toxic, non-irritating, and non-corrosive. With strong biodegradability and environmental friendliness, it is an ideal alternative to traditional biological preservatives that are flammable, explosive, or highly toxic.

The product is easy to use—simply add at a volume ratio of 0.1–0.5% and mix well to achieve effective antimicrobial activity.
