The Core Functionality of Alkazyme
Alkazyme is an alkaline proteolytic disinfectant detergent specifically formulated for the pre-disinfection and cleaning of reusable medical, surgical, and dental devices through immersion. Its unique composition includes a detergent system, a proteolytic enzyme, and a quaternary ammonium compound. The product is typically supplied in a stable, concentrated powder or soluble sachet form, which preserves the enzyme's efficacy until it is diluted for use. Once mixed with water, Alkazyme's alkaline pH, which is typically around 10.3, activates the proteolytic enzymes. This high alkalinity is crucial for breaking down complex organic material and enhancing the overall cleaning process.
Comprehensive Cleaning and Biofilm Removal
One of the most significant benefits of Alkazyme is its proven ability to effectively remove stubborn organic soiling and biofilms.
Dissolves Organic Debris
Thanks to its powerful proteolytic enzyme and alkaline formulation, Alkazyme rapidly dissolves proteins like blood, saliva, and other organic matter commonly found on medical instruments after use. This dissolving action is far more efficient than standard cleaning agents and is particularly effective when used in ultrasonic cleaners, where the agitation aids in the removal of contaminants from intricate crevices.
Eliminates Biofilm Contamination
Biofilm is a complex matrix of microorganisms and extracellular substances that can adhere to surfaces, especially on instruments with lumens or hard-to-reach areas. The alkaline pH of Alkazyme is specifically designed to act on the internal structure of these biofilms, breaking them down and preventing their mineralization. This targeted action is a key benefit, as biofilm can significantly impede the sterilization process if not properly removed beforehand.
Powerful Antimicrobial Efficacy
Alkazyme is not just a cleaner; it also acts as a powerful disinfectant, which is a critical advantage during the initial stages of instrument reprocessing. It provides significant antimicrobial activity against a broad spectrum of pathogens.
High Bioburden Reduction
By continuously disinfecting the contaminated wash water, Alkazyme significantly reduces the bioburden on instruments and minimizes the risk of cross-contamination. This contributes to a safer working environment and prepares instruments more effectively for final sterilization.
Broad-Spectrum Action
Independent laboratory tests have shown Alkazyme to be bactericidal, fungicidal, and virucidal, with activity against dangerous viruses such as HIV, Hepatitis B, and Hepatitis C. This broad-spectrum efficacy provides an extra layer of protection during handling and processing.
Water Softening and Instrument Protection
Another notable benefit is Alkazyme's integrated water-softening capability, which enhances cleaning performance and protects valuable instruments.
Softens Hard Water
Alkazyme contains powerful lime sequestering agents that transform hard water into soft water, optimizing the detergent's activity and preventing the formation of limescale deposits. Limescale can accumulate on instruments, causing damage and interfering with proper sterilization. By eliminating this risk, Alkazyme helps to extend the lifespan of medical equipment.
Non-Corrosive Formulation
Despite its powerful alkaline properties, Alkazyme is formulated to be compatible with a wide range of materials, including stainless steel, polycarbonate, and other plastics commonly used in medical devices. It is designed for prolonged immersion (up to 72 hours) without causing corrosion, provided it is used as directed and not with aluminum.
Operational Efficiency and Safety
- Long-Lasting Efficacy: The powder formulation ensures the product's enzymatic activity remains stable for up to eight days once reconstituted, providing a cost-effective and reliable solution for instrument soaking.
- User-Friendly: Clear dilution instructions and stable solution properties make Alkazyme easy to use in various clinical settings.
- Environmentally Friendly: Alkazyme is non-toxic, biodegradable, and free from harsh chemicals like aldehyde, chlorine, or phenols, making it a safer option for both users and the environment.
Alkazyme vs. Neutral Enzymatic Detergents
While both alkaline and neutral enzymatic detergents are used for medical instrument cleaning, they differ in their properties and specific advantages. The choice between them depends on the instrument type and cleaning needs, though Alkazyme's alkaline nature provides distinct benefits for protein-heavy soils and biofilm.
| Feature | Alkazyme (Alkaline Enzymatic) | Neutral Enzymatic Detergents |
|---|---|---|
| pH Level | High (pH ~10.5) | Neutral (pH ~7) |
| Primary Target | Proteins, organic matter, and biofilm | Broad-spectrum organic debris |
| Biofilm Removal | Highly effective; penetrates and dissolves biofilm structure | Less effective against persistent, mineralized biofilms |
| Water Softening | Contains sequestering agents to handle hard water | May be less effective in hard water conditions |
| Material Compatibility | Good, but unsuitable for aluminum | Very good; compatible with most materials |
| Cleaning Power | Superior for stubborn organic soils and protein hydrolysis | Gentle cleaning action |

Conclusion
For medical facilities requiring a powerful, effective, and reliable solution for the pre-disinfection of instruments, the benefits of Alkazyme are clear. Its unique alkaline enzymatic formulation provides superior cleaning by dissolving tenacious organic matter and eradicating stubborn biofilm. Coupled with its antimicrobial properties, water-softening capabilities, and protective, biodegradable nature, Alkazyme ensures that reusable medical devices are not only visibly clean but also safely prepared for the final sterilization process, helping to prevent cross-contamination and prolong instrument life.
