Hexadecyldimethylbenzylammonium Bromide (1627-Br/HDBAB)

CAS 3529-04-2

Hexadecyldimethylbenzylammonium Bromide (CAS 3529-04-2) is a high-purity quaternary ammonium compound widely used as a cationic surfactant, phase transfer catalyst, and antimicrobial preservative. It typically appears as a white to off-white crystalline powder or colorless to pale yellow liquid, offering excellent solubility in water and alcohols. This versatile chemical exhibits strong bactericidal activity against Gram-positive bacteria, fungi, and certain viruses, making it ideal for healthcare applications including topical antiseptics, oral care products, and medical device disinfection. In cosmetics and personal care, it functions as an effective preservative and antistatic agent in hair conditioners, lotions, and leave-on formulations. Industrial applications include water treatment biocide, textile processing aid, metalworking fluid additive, and corrosion inhibitor. With high active matter content (typically ≥95%) and controlled free amine levels (≤1.5%), it ensures consistent performance across pharmaceutical, cosmetic, and industrial sectors.

>> Main Uses

Hexadecyldimethylbenzylammonium Bromide (1627-Br/HDBAB, CAS 3529-04-2) serves as a versatile cationic surfactant and antimicrobial agent across multiple industries. In healthcare and medical applications, it functions as an effective antiseptic and preservative in topical creams, ophthalmic solutions, mouthwashes, and wound disinfectants due to its strong bactericidal activity against Gram-positive bacteria and fungi. Within cosmetics and personal care products, it acts as both a preservative to prevent microbial contamination and an antistatic agent in hair conditioners, facial cleansers, body lotions, and leave-on formulations, while its emulsifying properties enhance product stability. Industrial applications utilize this compound as a phase transfer catalyst in chemical synthesis, a biocide in water treatment and oilfield operations to control bacterial growth, a corrosion inhibitor in metalworking fluids, and a processing aid in textile manufacturing. Additionally, it finds use in biotechnological research for gene delivery systems, nanoparticle surface modification, and antimicrobial coating development.
