BBIT (2-Butyl-1,2-benzisothiazolin-3(2H)-one) is a broad-spectrum industrial biocide and preservative designed to provide long-lasting protection against bacteria, moulds, yeasts and algae. With excellent heat resistance, UV stability, low water solubility and broad pH stability, BBIT is suitable for a wide range of water-based products and polymer materials. This article introduces the key properties, antimicrobial mechanism, applications and recommended use levels of BBIT, as well as important safety and transport considerations.

Dibutyl Fumarate (DBF) is a reactive internal plasticizer and copolymer monomer used in polymer, coating and adhesive industries. Different from ordinary plasticizers, DBF chemically bonds to polymer chains to achieve non-migration, non-precipitation and long-term stability. It is a safe, eco-friendly non-phthalate material for industrial fine chemical applications.

As demand for effective mosquito and insect protection continues to grow, formulators and manufacturers are looking for reliable active ingredients that deliver consistent repellent performance. DEET (N,N-Diethyl-meta-toluamide) is one of the most widely used insect repellent active ingredients, valued for its proven performance and versatility across a wide range of personal and household protection products.

DMDMH 55% (1,3‑Dimethylol‑5,5‑Dimethylhydantoin 55% aqueous solution, CAS 6440‑58‑0) is a ready‑to‑use broad‑-spectrum liquid preservative for various water‑based systems. With 55±2% active content and free formaldehyde ≤1.0%, this cosmetic‑grade hydantoin‑based biocide features water solubility, wide pH‑temperature adaptability and excellent surfactant compatibility. It inhibits bacteria, yeast and mold, effectively preventing spoilage, off‑odor and stratification in end products. Widely applied in cosmetics & personal‑care items, textile auxiliaries, water‑borne coatings, adhesives and household‑industrial detergents, it outperforms solid DMDMH powder and isothiazolinone preservatives in production convenience, spectrum coverage and cost‑efficiency. Dalian Sinobio Chemistry supplies qualified batches with test reports, sample support and custom anti‑corrosion technical solutions for global buyers.

Benzalkonium Chloride (BAC/BK) is a quaternary ammonium cationic surfactant and broad-spectrum biocide effective against bacteria, fungi, algae and enveloped viruses, stable at pH 4–11 with low corrosion. It is widely used in disinfection, personal care, water treatment, medical, textile and industrial chemical fields. Dalian Sinobio Chemistry supplies customized BAC products with adjustable alkyl chain ratios, variable concentrations and solvent systems, along with strict batch inspection, complete COA/MSDS and professional formula technical support for global buyers.

The cancellation of export VAT rebates for phosphorus flame retardants and DBNPA speeds up consolidation in China’s fine chemical industry. Low-cost small manufacturers are under financial strain, while large integrated suppliers gain market advantages via technological innovation. Producers are shifting R&D to high-end flame retardants for EV batteries and eco-friendly DBNPA biocides complying with EU standards. Global buyers will value stable supply and product quality over rock-bottom prices. In the long run, the policy supports ESG development and is expected to stabilize market prices within one year.
