Cationic surfactants are basically soaps or detergents, in which the hydrophilic, or water-loving, end contains a positively-charged ion, or cation. Typical examples are trimethylalkylammonium chlorides, and the chlorides or bromides of benzalkonium and alkylpyridinium ions. All are examples of quats, so named because they all contain a quaternary ammonium ion. Most cationic surfactants find use as anti-microbials, anti-fungals, etc. (Benzalkonium chloride (BAC), Cetylpyridinium chloride (CPC), Benzethonium chloride (BZT). Cationic surfactants also have applications in fabric conditioners and soil repelling agents.
Caustic usually refers to caustic soda which is Sodium hydroxide a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. Potassium hydroxide is also referred to as caustic. Silicate alkalinty is sometimes referred to as non-caustic alkalinity.
A step at which control can be applied and is essential to prevent or eliminate a food safety hazard or reduce it to an acceptable level.

The CIC document describes a method needed to ensure that the item of equipment or area achieves the standards laid down by the company. It may be prudent for complicated items of equipment and machinery to include photos or diagrams to further explain the strip-down or key inspection points. The document should display all the necessary requirements to complete that particular cleaning task, including information such as: • Cleaning strategy and procedures, • Responsibility for cleaning, inspection and determining if engineering assistance is required, • Cleaning equipment, including chemical dosing and application, • Detergents/disinfectants and their concentrations, • Essential safety information, such as minimum personal protective equipment requirements, • Cleaning frequency, • Cleaning procedure (including an overview of the strip-down of equipment) and • Key inspection points.
The main pump that is used to feed the CIP solutions from the CIP set to the plant being cleaned.
A pump that is used to return the CIP solutions from a vessel back to the CIP set.
The suitability of equipment to be freed from soil easily.
The removal of soil, food residues, dirt, grease or other objectionable matter. (Codex)
Room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room, and in which other relevant parameters e.g. temperature, humidity, and pressure, are controlled as necessary. (EN ISO 14698-1)
European Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures came into force on 20 January 2009 in all EU Member States, including the UK. It is known by its abbreviated form, ‘the CLP Regulation’ or just plain ‘CLP’. The CLP Regulation adopts the United Nations’ Globally Harmonised System on the classification and labelling of chemicals (GHS) across all European Union countries, including the UK.
The result of a process where a different material is deposited to create a new surface.
The cleanability of equipment relative to a reference.
The volume reduction achieved by concentration, i.e. the ratio of initial volume of feed to the final volume of concentrate/retentate. Relevance to membrane filtration.
In relation to equipment and parts or other elements e.g. of building, and not in the context of product and consumer. All normal or reasonably anticipated operating conditions, including those of cleaning. These should set limits for variables such as time, temperature and concentration.
A type of floor which is constructed to form a pathway of moderate electrical conductivity between equipment, people and the floor. This floor is designed to prevent the buildup of hazardous electrostatic charges in areas where flammable gases are used. The resistance of such flooring must be maintained between 25,000-100,000 ohms. Special polish and maintenance products are available for this flooring.
Ability of a solution to conduct electricity. Conductivity is the inverse of resistance.
An instrument that measures the conductivity of a solution. They can have electrodes that measure the resistance across the solution or be contactless and use the inductance of a solution passing inside a coil.
The time that a detergent or a disinfectant remains on the surface being treated.
Any biological or chemical agent, foreign matter or other substance not intentionally added to food, which may compromise food safety or suitability.
The introduction or occurrence of a contaminant in food or food environment.
Any action and activity that can be used to prevent or eliminate a food safety hazard or reduce it to an acceptable level. (Codex)
Manual cleaning of dismantled equipment. The main part of the installation may remain fixed in a position but parts may be removed to another point for cleaning.
Any action to be taken when the results of monitoring at the CCP indicate a loss of control. Action taken to eliminate or reduce the causes of nonconformity, defect or other undesirable situation after a deviation has been detected, in order to minimize or prevent its recurrence. Every control point in a Quality Monitoring system must include the corrective action to be taken in case of deviation.
COSHH stands for 'Control of Substances Hazardous to Health' and under the Control of Substances Hazardous to Health Regulations 2002, employers need to either prevent or reduce their workers' exposure to substances that are hazardous to their health. A safety data sheet does not represent a COSHH assessment
A crack with an opening accessible to contaminants. For example a narrow opening or fissure either in the bulk of a material or between two closely fitting components, such as a flange and its gasket. Typically, a crevice has a depth more than 20 times the width of its opening. Crevices may not only harbour soils and micro-organisms and be inaccessible to cleaning agents, but may also cause accelerated corrosion of the bulk material, rapidly increasing the size of the crevice.
