Octadecyl Dimethyl (Ethylbenzyl) Ammonium Chloride (C18-EB)

CAS 29661-60-7

Hexadecyl Dimethyl (Ethylbenzyl) Ammonium Chloride (CAS 29661-60-7) is a high-performance quaternary ammonium compound featuring a long C18 alkyl chain and an ethylbenzyl functional group, which imparts enhanced surface activity, thermal stability, and broad-spectrum antimicrobial efficacy against bacteria, fungi, and algae. This cationic surfactant is readily soluble in water and polar organic solvents and serves as an effective bactericide, algicide, and slime control agent in industrial water treatment and oilfield applications, a softening and antistatic agent in the textile industry, and a key active ingredient in hospital-grade disinfectants and sanitizers, with typical specifications including free amine ≤ 2.0%, pH (1% solution) 6.0–7.5, and color (APHA) ≤ 100 for refined grades.

>> Main Uses

Octadecyl Dimethyl (Ethylbenzyl) Ammonium Chloride (C18-EB, CAS 29661-60-7) is primarily used as a broad-spectrum bactericide, algicide, and slime control agent in industrial water treatment, cooling systems, paper mills, and oilfield injection applications to prevent biofilm formation and microbial corrosion; as a cationic softening and antistatic agent in the textile industry for synthetic fibers such as acrylic and polyester, improving fabric handfeel and reducing static buildup; and as an active antimicrobial ingredient in hospital-grade disinfectants, surface sanitizers, and industrial cleaning formulations due to its effective biocidal activity against bacteria, fungi, and algae.
