Cetrimide

Cetrimide (CAS 8044-71-1), also marketed as CTAB (cetyltrimethylammonium bromide), is a quaternary ammonium compound used across pharmaceutical, personal care, and agricultural sectors. It functions as a cationic surfactant with broad-spectrum antimicrobial activity.

This versatile chemical functions primarily as a preservative, disinfectant, and emulsifying agent in formulated products. In pharmaceutical manufacturing, it is incorporated into topical antiseptic creams and wound cleansing solutions.

It is also utilized in ophthalmic preparations where microbial control is a regulatory requirement. Personal care formulators use it in anti-dandruff shampoos and conditioning rinses for its specific cationic charge.

This charge enables substantivity to hair and scalp while delivering a reliable preservative effect. In agricultural formulations, it acts as an emulsifier and wetting agent in various pesticide concentrates.

These applications improve active ingredient dispersion and surface coverage during application. Industrial and institutional cleaning products also rely on it for combined degreasing and bactericidal performance on hard surfaces.

The material is supplied as a white to off-white powder or as aqueous solution, typically at concentrations of 40% or 50% w/v. Established grades include BP, Ph. Eur., and USP standards.

These quality certifications are standard requirements for pharmaceutical procurement and high-end manufacturing. Technical grade material is also available for agricultural and industrial cleaning applications.

These industrial options are suitable for use where compendial certification is not required. Our supply chain ensures consistent quality and availability for all global manufacturing and formulation needs.
