Shandong Kairui Chemistry Co., Ltd. offers D1021, a high-performance didecyl dimethyl ammonium chloride (Didecyl Dimethyl Ammonium Chloride) that represents the gold standard in quaternary ammonium compound biocides. With CAS No. 7173-51-5 and a molecular formula of C₂₂H₄₈ClN (molecular weight 362.1), D1021 delivers unparalleled antimicrobial efficacy across healthcare, food processing, and industrial applications.
DDAC is a twin-chained cationic quaternary ammonium compound that functions as a broad-spectrum membrane-active biocide. Its dual decyl chains provide enhanced antimicrobial activity compared to mono-chain quaternary ammonium compounds, with a minimum inhibitory concentration (MIC₅₀) that is 2–3 times lower than benzalkonium chloride against Gram-negative bacteria and fungi. This superior efficacy means lower active-ingredient volumes are required per disinfection event, reducing procurement costs and environmental quaternary ammonium compound loading.
DDAC exhibits broad-spectrum bactericidal and fungicidal activity. It is effective against a wide range of microorganisms, including bacteria, fungi, algae, and enveloped viruses. The compound is stable over a wide pH range and can be formulated into various disinfectant and sanitizer products. Significantly, DDAC has received specific FDA clearance for no-rinse food contact surface sanitization at up to 240 ppm active, eliminating the need for post-application rinses in food processing facilities.
The applications of D1021 are extensive. It is used as a disinfectant and sanitizer in healthcare settings, hospitals, and hotels. In food processing, it serves as a surface sanitizer. Industrial applications include use as an algaecide, bactericide, fungicide, wood preservative, deodorant, water treatment biocide, and preservative.
Shandong Kairui Chemistry Co., Ltd. is your trusted partner for high-quality D1021. Choose DDAC for superior antimicrobial protection across your operations.
