NaDCC effervescent disinfectant tablets for hard surface and body fluid spill decontamination
Description
Presept Disinfectant Tablets - 2.5g x 100 are effervescent sodium dichloroisocyanurate (NaDCC) chlorine-releasing tablets supplied for hospital, laboratory and general healthcare hard-surface disinfection. Each 2.5 g tablet provides a controlled dose of available chlorine when dissolved in water, giving a broad biocidal spectrum against bacteria (including MRSA), viruses (including HIV and Hepatitis B), fungi and spores. Presept tablets maintain good activity even in the presence of blood and other organic matter, making them suitable for body fluid spillages as well as routine surface decontamination. The tablets are compact and stable in storage, with full biocidal activity maintained up to the moment of use, and allow safe, simple and accurate preparation of working solutions in a range of concentrations.
Bnefits
Broad biocidal spectrum, effective against a wide range of bacteria, viruses, fungi and spores when used at recommended concentrations.
Better activity in the presence of organic matter (e.g. blood and body fluids) than traditional hypochlorite solutions, allowing reliable disinfection of spillages.
Active ingredient NaDCC (troclosene sodium) provides controlled, sustained release of free available chlorine for consistent performance.
Effervescent tablet format is compact in storage and easy to handle, with long-term stability prior to use.
Accurate dosing: each tablet delivers a known quantity of available chlorine, simplifying preparation of standardised working solutions.
Rapid dissolution in water with clear dilution instructions for different applications (general surface cleaning, high-risk spillages, instrument decontamination where appropriate).
Compatible with certain detergents, supporting combined cleaning and disinfection regimes where recommended.
Reduced odour and improved handling characteristics compared to some traditional hypochlorites.
Economical for routine infection-control use across multiple departments.
Practical and convenient approach to hard-surface and spill disinfection in hospitals, clinics, laboratories and other healthcare environments.
Indications
General hard-surface disinfection in hospitals, clinics, dental surgeries, laboratories and other healthcare facilities.
Decontamination of environmental surfaces such as floors, worktops, trolleys, beds and sanitary fittings where chlorine-based disinfectants are appropriate.
Disinfection of body fluid spillages including blood, vomit, urine and faeces, using higher-strength solutions as per local protocols.
Preparation of chlorine solutions for cleaning and disinfecting non-invasive medical equipment and accessories compatible with chlorine.
Use in infection-control protocols during outbreaks of gastrointestinal and respiratory pathogens where chlorine disinfection is recommended.
Use in central sterile supply, endoscopy or decontamination units when NaDCC tablet-based chlorine solutions are specified in local procedures (not as a high-level disinfectant or sterilant unless explicitly validated and indicated).
Composition
Active ingredient: sodium dichloroisocyanurate (NaDCC, troclosene sodium) – 2.5 g per effervescent tablet (equivalent to approximately 1.4 g available chlorine when dissolved).
Effervescent tablet base containing inorganic salts and organic acids to aid dissolution and solution clarity.
Tabletting excipients (e.g. binders and fillers) appropriate for chlorine-releasing disinfectant tablets.
Formulation
Solid, white effervescent NaDCC disinfectant tablets, each weighing 2.5 g.
Chlorine-releasing formulation that generates aqueous solutions containing free available chlorine at defined ppm levels when dissolved in water.
Stable, compact formulation designed to maintain potency over shelf life when stored in the closed original container.
Typically, one 2.5 g tablet dissolved in 10 litres of water yields approximately 140 ppm available chlorine for general environmental disinfection, with higher concentrations prepared by using more tablets and/or smaller volumes of water according to the manufacturer’s dilution chart.
Packaging
Supplied in a resealable, tamper-evident plastic tub or drum containing 100 x 2.5 g effervescent tablets.
Pack labelling includes product name, batch number, expiry date, storage conditions, hazard and precautionary statements and dilution instructions.
COSHH / safety data sheet and technical data sheet available from the manufacturer or distributor.
Outer transit packaging (cartons) used for bulk supply to hospitals and distributors.
Usage
For professional use in healthcare, laboratory and institutional settings; always follow local infection-control policies and the manufacturer’s instructions for dilution and contact time.
Determine the required available chlorine concentration for the intended application (e.g. general surface disinfection vs body fluid spillage) and refer to the dilution table provided in the pack literature.
Add the required number of tablets to a known volume of clean, cold water in a suitable plastic container and allow them to dissolve completely before use.
Typical general-purpose environmental disinfection may use lower-concentration solutions (e.g. one tablet in 10 litres of water), while body fluid spillages and high-risk contamination usually require stronger solutions (e.g. several tablets per litre) as specified in local protocols.
Apply the prepared solution to pre-cleaned surfaces using cloths, mops or appropriate cleaning equipment, ensuring thorough wetting.
Allow the solution to remain in contact with the surface for the recommended contact time (often 10–30 minutes, depending on the target organisms and local guidelines) before rinsing if necessary or allowing to air-dry.
Prepare solutions fresh as directed (commonly daily or more frequently) and discard any unused solution after the maximum recommended in-use period, typically within 24 hours.
Do not mix Presept solutions with acids or ammonia-based cleaners; contact with acids releases toxic chlorine gas.
Use appropriate personal protective equipment (PPE) such as gloves and eye protection when handling tablets and solutions, especially at higher concentrations.
Do not ingest, do not use for hand or skin disinfection, and do not use on fabrics or materials that are incompatible with chlorine (e.g. some metals, rubber or coloured textiles) without confirming compatibility.
Contraindications
Not for ingestion, injection or any internal use.
Not for use as a hand or skin disinfectant or on mucous membranes.
Do not use on surfaces or equipment known to be incompatible with chlorine-based disinfectants (e.g. some metals, natural rubber, certain textiles, or electronics) without confirming compatibility.
Do not mix with acids, ammonia or other cleaning agents that can react with chlorine; dangerous gases may be released.
Use with caution in poorly ventilated areas due to potential release of chlorine-containing vapours.
Individuals with known hypersensitivity to chlorine-releasing agents or strong oxidising chemicals should avoid direct contact.
Not suitable as a terminal sterilant or high-level disinfectant for invasive medical devices unless specifically validated and indicated in the manufacturer’s instructions.
Adverse Effects
Contact with eyes can cause serious irritation and redness; splashes should be rinsed immediately with plenty of water and medical advice sought if irritation persists.
Prolonged or repeated skin contact, especially with concentrated solutions or undissolved tablets, may cause irritation or dermatitis.
Inhalation of dust from tablets or vapours from concentrated solutions may cause respiratory irritation, coughing or shortness of breath.
Ingestion may cause irritation or corrosion of the mouth, throat and gastrointestinal tract and requires urgent medical attention.
Very toxic to aquatic life with long-lasting effects; inappropriate disposal may harm the environment.
Contact with acids may liberate toxic chlorine gas, which can cause severe respiratory irritation or distress if inhaled.
Storage Conditions
Store in the original, tightly closed container in a cool, dry, well-ventilated place.
Keep away from moisture, direct sunlight, heat sources and naked flames.
Store away from acids, ammonia, organic materials, reducing agents and combustible substances.
Protect from physical damage and do not allow tablets to become damp, as this may lead to decomposition and loss of activity.
Keep out of reach of children and unauthorised personnel.
Observe any additional storage temperature and stability information stated on the product label or safety data sheet.
Duration
For environmental and spill disinfection, typical contact times for NaDCC solutions are in the range of approximately 10\u201330 minutes depending on concentration, level of contamination and local infection-control protocols. Solutions should be prepared fresh as recommended (usually daily) and discarded after the maximum in-use period, generally within 24 hours.
Onset
Biocidal activity begins as soon as the tablet has fully dissolved and free available chlorine is present in solution; effective microbial kill is achieved when the prepared solution is applied at the correct concentration and maintained for the recommended contact time.
