Benzethonium Chloride CAS 121-54-0

What Benzethonium Chloride Is

Benzethonium chloride is a quaternary ammonium salt built from a benzyl dimethyl ammonium head, two ethoxy groups and a branched octyl phenol tail. It arrives as a white to off-white crystalline powder that dissolves freely in water and ethanol and produces stable foam, the classic profile of a cationic surfactant. The positive charge drives the molecule onto negatively charged microbial and fabric surfaces, which gives the material its antimicrobial, conditioning and antistatic behavior. It is known in the trade as Hyamine 1622 and is listed in USP, BP and Ph Eur. UATChem supplies industrial, cosmetic and pharmacopoeia grades, with active content and loss on drying reported on the COA for each lot.

Disinfection, Personal Care and Other Uses

• Disinfectants and sanitizers. A quaternary ammonium active in hard surface, skin and mucous membrane sanitizers for hospital, food, catering and veterinary hygiene.
• Personal care and wipes. The antimicrobial and preservative ingredient in wet wipes, hand washes, mouthwashes, deodorants and cosmetic formulations.
• Detergents and softeners. A cationic surfactant for fabric softening, antistatic, emulsifying and conditioning products.
• Analytical reagent. Hyamine 1622 is used in two phase titration of anionic surfactants and in protein precipitation work.

Typical Specifications

Industrial, cosmetic and pharmacopoeia grades differ in active content, loss on drying and residue limits; values are reported on the COA for each lot, and the physical constants below identify the material.

Packaging, Documents and Ordering

• Packed in 25 kg kraft paper bags or fiber and blue drums with liner, palletized for export; packs stay sealed, dry and cool and protected from moisture.
• Concentrated powder and strong solutions irritate or may burn skin and eyes, are harmful if swallowed and are very toxic to aquatic life, so gloves, goggles and ventilation are used and release to waterways is avoided, with transport classification on the SDS. Every lot carries a COA with active content, loss on drying and melting point, plus TDS and SDS; USP, BP or Ph Eur documents and samples are supported.
• For a quote, UATChem needs the grade (industrial, cosmetic or pharmacopoeia), quantity, packing and destination port.
