reagent preservatives

1.BND has the function of both surfactant and antiseptic antibacterial agent, easy to degrade, easy to cleanand does not contain secondary amines 2.BPRG-9 Antibacterial agent for in vitro diagnostic reagent has a wide range of microbial growth inhibition effect, good compatibility and stability, low toxicity and biodegradable, so that the diagnostic reagent has a longer validity and open bottle validity.

1. This product is a new generation of synergistic fungicides without CMIT, AOX (adsorbable organic halides) and VOC (organic volatiles). 2. BRPG 7 is suitable for a wide range of pH, and can be used in the range of 2.0-10.0. 3. MB5 is free of organic solvents, halogenated organic compounds, formaldehyde releasers or divalent metal ions

1.Broad-spectrum and long-term killing of a variety of bacteria, fungi and yeast, the use of a concentration of 0.1%-0.4% (w/w) can achieve good bacteriostatic effect. 2.It has good compatibility with various emulsifiers, surfactants and other components, and is compatible with alcohol and water in any proportion. 3. The applicable pH range is wider than that of similar products, and pH 2-14 can be used.

1. Phenoxyethanol is free of heavy metals, and has clear index control for dioxane, diethylene glycol monophenyl ether and phenol, so it has higher purity and lower odor. It is currently one of the few preservatives generally recognized internationally. 2. Phenoxyethanol has excellent compatibility, and has very good compatibility with various surfactants. 3. Phenoxyethanol will not change the smell and color of cosmetics, external medicines and toys.

1. Ready-to-use aqueous solution, which can be mixed with water in any ratio. 2. In TRIS, TES and HEPES buffer solutions, it is still very stable at pH 7. 3. The content of active components can be detected by HPLC.
