Cetrimide holds proven efficacy against a broad spectrum of microorganisms


What is Cetrimide?

FeF Cetrimide Ph.Eur. is a surfactant or surface-active antiseptic agent. It has a various number of antibacterial, antifungal, and antiviral (against enveloped viruses) properties and can be applied to the skin or mucous membranes to avoid or minimize the risk of infection.

Cetrimide uses

As a pharmaceutical ingredient, Cetrimide is used as an active in various products mainly for topical use in sprays, gels, and creams for a range of purposes, where it helps cleaning burns and wounds, disinfecting skin before injections or surgery, and treating fungal infections or nappy rash.

It also acts as an antimicrobial preservative, keeping pharmaceutical formulations free from microbial contamination, ensuring patient safety.

Cetrimide applications

Antiseptic agent and disinfectant

A various number of hospital antiseptic solutions are used for both hand disinfection and instrument disinfection. Effective concentrations of Quats in these products are usually ranging between 0,5% and 3%. Concentrated solutions for further dilution can contain between 5% and 15% Quats. Novo Nordisk Pharmatech’s Cetrimide (Strong Cetrimide) and Benzalkonium Chloride are widely used in these formulations, where Cetrimide is often combined with chlorhexidine.

Diagnostic test and analysis

Diagnostic reagent applications necessitate products with very exact specifications. In a number of diagnostic reagents, the level of impurity in the raw material may lead to intolerable variations in the performance of the reagent.

Novo Nordisk Pharmatech’s Quats are proven to be notably superior in diagnostic reagents compared to other less pure compounds. Cetrimide and CTAB are for instance utilized in the purification process of heparin.  Additionally, Cetrimide is employed in special reagents, for example for the counting of blood cells (Bakers reagents).

Topical formulations

It is crucial to use the purest and safest ingredients for formulations that are making contact with healthy or damaged epithelial tissue.

Our Cetrimide is frequently found in antiseptic creams used in the treatment of nappy rash, eczema, psoriasis, acne, and other dermatoses at concentrations varying from 0.1 to 1%.

Dental treatment

Cetrimide also provides a positive reaction within the area of oral and dental treatment. A conducted study reported that after 14 days of 1% Cetrimide application, the viability of Enterococcus faecalis in an infected human dentine model was significantly reduced in comparison with 2% CHX gel and calcium hydroxide paste.

What is the difference between Cetrimide and CTAB (Cetrimonium Bromide)

From a chemical point of view, Cetrimide and CTAB have very similar characteristics. However, the one difference is that we manufacture Cetrimide using an amine with 14 carbons (C14) and CTAB is made using an amine with 16 carbons (C16). Both quats have the same properties, but CTAB is less adsorbent and a bit less soluble than Cetrimide.

Cetrimide is commonly used in Europe, Australia, the Middle East, and Africa whereas CTAB is more common in North America. Cetrimide is described in monographs in BP and PhEur, but not in USP/NF. On the contrary, CTAB is only described in the USP/NF.
