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.

The abolition of China’s 13% export VAT rebate for phosphorus flame retardants and DBNPA pushes up procurement costs for global buyers. Combined with volatile upstream phosphorus raw material prices, suppliers keep adjusting quotations. Widely adopted in plastics, new energy, water treatment and coatings, these chemicals squeeze overseas end-users’ profits. While large manufacturers ease pressure through internal optimization, traders transfer cost increases downstream. Experts suggest long-term contracts to hedge spot price volatility.

Issued via China’s Announcement No.2 of 2026, a new policy cancels the original 13% export VAT rebate for phosphorus flame retardants and industrial biocide DBNPA starting April 1, 2026, judged by customs declaration date. Covering TCPP, ammonium polyphosphate and other mainstream chemicals, the policy aims to upgrade resource-intensive chemical industries. It brings immediate cost hikes for global importers, triggering frequent quotation adjustments and expected long-term price fluctuations across the phosphorus chemical supply chain.

DMDS (CAS 624-92-0) with 99.5% high purity is a top-tier presulfiding agent for petrochemical hydrogenation catalysts. It owns high sulfur content of over 68.1%, decomposes stably at moderate temperatures to activate catalysts and avoid coking, outperforming DMS in efficiency and cost control. Widely applied in refineries, ethylene plants and fine chemical synthesis. As a large Chinese manufacturer with 20,000-ton annual capacity, we supply certified products, customized technical schemes and stable global logistics for worldwide industrial clients.

AEO2 (CAS 68439-50-9) is a lipophilic eco-friendly non-ionic surfactant synthesized from C12-14 fatty alcohol. It features stable acid-alkali resistance, low foam and full biodegradability compliant with REACH. With strong emulsification, penetration and degreasing capacity, it mixes well with all surfactant types. Widely used in industrial cleaning, textile, daily chemicals and pesticide emulsifiers. As a professional manufacturer, we offer strict quality testing, spot stock, custom packaging and global logistics support for worldwide buyers.

DEHA 85% is a widely used water-soluble amine derivative.
