BIOTREND® MB5 is a highly cost-effective broad-spectrum industrial preservative. The use of these dual actives offers numerous unique benefits to the formulator, with enhanced broad-spectrum synergy compared to BIT-only preservatives, especially against Pseudomonas sp. Due to its cost-effectiveness and ease of use, BIOTREND® MB5 can easily replace formaldehyde-based and formaldehyde-releasing preservatives in a wide range of aqueous industrial products.

Product Features
  • Biotrend® MB5 provides broad antimicrobial efficacy against bacteria, yeasts and fungi often effective where other preservatives fail. As a result of its’ excellent thermal, pH and chemical stability, Biotrend® MB5 provides longer-term protection compared to other chemistries that may deteriorate over time due to pH or temperature shifts during storage.
  • Biotrend® MB5 prevents microbial deterioration of products and resulting consequences such as phase separation, odor build-up, gas buildup and changes in viscosity.
  • Biotrend® MB5 penetrates the cells of microorganisms, reacts with vital parts of the cells and inactivates important substrates and enzymes necessary to normal cell function. These relatively unspecific reactions exhibit a bactericidal effect and minimize adaptation or the development of microbial resistance.
  • Excellent long-term efficacy due to the dual active synergy and complementary activity, especially against pseudomonas sp
  • Used as a preservative of aqueous and water miscible chemicals and technical products
  • Broad antimicrobial efficacy against bacteria, yeasts and fungi
  • Often effective where other preservatives fail, especially at critical temperature and pH-values
  • Free from formaldehyde, formaldehyde releasers, phenolics, heavy metals, halogens
  • Does not settle, dry-out or flake like dispersion products for easier pumping and handling

Formulation Applications

Biotrend® MB5 is highly suitable for the preservation of a wide variety of aqueous-based products due to its broad spectrum of antimicrobial activity and good thermal and chemical stability.
Biotrend® MB5 shows the highest efficacy in a wide pH range of pH 4 - 10 and is chemically stable from pH 2 - 12 and light stable. Experience shows that compatibility with most products and raw materials is excellent, although compatibility testing is recommended for specific formulations.
