G-Cide Technology

Award winning technology

Gold Medal awarded in Geneva

  G-cide Technology was awarded a gold medal at the

26th Congress of Inventors in Geneva in 1998.

The award was based on three criteria


  • Efficacy of the disinfectant

  • Biodegradability

  • User and environmentally friendliness

 The disinfectant was chosen out of 52 competitors.


Taming the Tiger

Stabilising Glutaraldehyde.

Glutaraldehyde is a widely used, effective disinfectant. Glutaraldehyde’s applications are limited due to is toxic nature, which requires that it needs to be handled and managed carefully, according to occupational health and safety standards. The application of G-cide technology renders glutaraldehyde pH neutral, non-corrosive, biodegradable and user friendly. The development of G-cide technology has been a breakthrough in anti-microbial, anti-viral and anti-fungal disinfection

The application of G-cide technology renders glutaraldehyde pH neutral, non-corrosive, biodegradable and user friendly, which significantly improves the usage possibility of glutaraldehyde. This is done by taking glutaraldehyde and complexing it with a non ionic surfactant resulting in a stabilised product

Allows glutaraldehyde solutions to be safely stored for a period of at least six months without the glutaraldehyde polymerizing or the pH dropping below 5.0, thus improving the shelf life of products, handling and efficacy.

Since 2006 the G-cide product has been improved upon in the following ways:


  • We have enhanced the biocide so it can give a better efficacy at a lower concentration as before.

  • We have increased the non volatility by ten fold by adding a different dilutent.

  • The biocide is registered with the CTFA and is listed in the compendium of cosmetic ingredients as INCI:- Glutaral C11-C15 Pareth 9

  • The Biocide has been further tested to show it is less cytotoxic than Chlorhexidine, Gluconate, Parabens, Glutaraldehyde and Triclosan

  • New products are being manufactured utilising G-cide +polymer 


Uses and issues with unstabilised form.


It's an organic compound widely used as disinfectant and as a preservative. It's toxic, colourless chemical, commonly available in aqueous solutions, which typically contain about 0.5% to 20% active glutaraldehyde. It's primary use is as a disinfectant in the medical sector, where it is commonly used as a cold sterilant to disinfect and clean heat-sensitive medical, surgical and dental equipment.

Glutaraldehyde is affective against a range of microorganisms including spores, fungi and viruses

In products such as Cidex, Aldesen, Hospex, Sporicidin, Omnicide, Matricide, Wavicide and others. The World Health Organisation's List of Essential Medicines includes it as one of the most effective products required in a functional health system. 

Additional uses include industrial water treatment, leather tanning and as a chemical preservative / biocide in home care products.

Unstabilised issues:

  • High toxicity - 1% solution of glutaraldehyde is poisonous for human and animals alike and any product containing more than 0.5% glutaraldehyde solution is consequently labelled as hazardous

  • Causes respiratory issues

  • Acts as a contact allergen, giving rise to contact dermatitis, usually on the hands but occasionally on the face

  • Skin sensitization from contact with glutaraldehyde has been documented in endoscopy nurses, dental assistants, x-ray technicians, hospital maintenance and cleaning staff, and funeral service employees 

  • Environmentally hazardous - in its unstabilised form is corrosive as well as an irritant

  • High levels of precaution therefore need to be undertaken in order to reduce occupational, as well as environmental, exposure to glutaraldehyde, which is a costly for global manufacturers and distributors
