     Editor’s note: Cleaner Times wishes to thank DECO Products Inc. and Vector Laboratories for their help in updating this Chemical Glossary in 2022, which previously was published in the August and October 2012 issue of Cleaner Times. 

     In 2012 the assistance of Cardinal Chemical; Dominion Restoration; Etowah Chemical Sales and Service; ITD Inc.; KO Manufacturing Inc.; Prosoc, Inc.; Royal Custom Products Inc.; and Xterior Sales and Service was greatly appreciated. Additional sources included the University of Montana MSDS Dictionary and The Soap and Detergent Association. 


  

     An asterisk signifies an ASTM definition. Many of the definitions are more focused on the cleaning setting than on chemical rigor.

     Effective pressure washing is a process that consists of five primary elements—pressure, flow, temperature, time, and chemicals. Because each individual cleaning application is a bit unique, the primary elements of pressure washing vary with each application. While the first four elements (pressure, flow, temperature, and time) can usually be determined on the spot, the fifth element—chemicals—requires some particular insights.

     Determining which chemical product to use in a particular cleaning application requires an understanding of the chemicals, and that begins with a basic understanding of chemical terms. The following listings are offered as a help.

– A –

ACC—American Chemistry Council, formerly the Chemical Manufacturer’s Association (CMA)

ACGIH—American Conference of Governmental Industrial Hygienists

ANSI—American National Standards Institute—ANSI’s mission is to enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems and safeguarding their integrity.

ASTM International—ASTM International, formerly American Society for Testing and Materials, is a developer of international voluntary consensus standards. ASTM standards are developed by committees of relevant industry professionals who meet regularly in an open and
transparent process to deliver standards, test methods, specifications, guides, and practices.

AOAC—Association of Official Analytical Chemists

Acid—A chemical substance whose properties include the ability to react with bases or alkalis in water solutions to form salts. Always has a pH less than 7. Turns blue litmus paper red. A pH of 1 would indicate a strong acid.

Acid inhibitors—Chemicals that greatly reduce the attack of acids on metal surfaces. Inhibitors can prevent up to 99 percent of the damage caused by acids.

Acridity—The choking effect resulting from an alkaline-based product. There is no smell coupled with acridity. Bitter taste is associated with alkalinity. 

Active solvent—A solvent that can dissolve a resin by itself.

Acute effects—Short-range or immediate effects of chemicals on humans.

Additive—Any substance incorporated into a base material, usually in low concentrations, to perform a specific function. E.g., antioxidants, stabilizers, colorants, inhibitors, preservatives, thickeners, etc.

Alcohol—A broad class of hydroxyl-containing organic compounds occurring naturally in plants and made synthetically from petroleum derivatives such as ethylene. Alcohols perform several functions in cleaners: control viscosity, solubilize ingredients, and provide low temperature stability.

Alkali—A chemical substance (such as potassium hydroxide or sodium carbonate) that reacts with and neutralizes an acid. Has a pH above 7. In concentrated forms, may attack paint and some metals. Turns red litmus paper blue. 

Amphoteric surfactant—Contains both positively charged and negatively charged groups in the same molecule. Their cationic nature dominates under acidic conditions while they display the characteristics of an anionic surfactant under basic or alkaline conditions. Suitable for use in shampoos and personal care products.

Anhydrous—Refers to a substance that contains no water. For example, caustic soda beads are anhydrous.

Anionic surfactant—A surfactant derived from an aliphatic or araliphatic hydrocarbon and found most commonly in the form of a sodium salt, in which the detergency and other properties depend in part on the negatively charged anion of the molecule; hence the name “anionic.”

Anodized aluminum (anodic coating)—An AlO2 coating chemically bonded to an aluminum surface. The objective is to prevent oxidation of normal aluminum. Anodized aluminum usually looks as if it has a satin or colored finish.

Auxiliaries—See Additive.

BOD—Biological Oxygen Demand

Bifluoride salts—Salts containing fluoride that, when dissolved in water, release fluoride ions for the purpose of cleaning masonry surfaces. Typically used in restoration cleaning.

Bimetallic (galvanic) corrosion—Corrosion resulting from interaction between dissimilar metals. Can be accelerated by cleaning processes; for example, if a joint between aluminum and another metal is hit with acid, the acid forms an electrolyte that fosters corrosion that often results in a black streak.

Biodegradability—The capability of organic matter to be decomposed by biological processes. Specifically, the rate at which detergents, pesticides, and other compounds may be chemically broken down by bacteria and/or natural environmental factors.

Bleach—A product that will clean, whiten, brighten, and remove stains on hard surfaces. Chemically, an oxidizer; often contains hypochlorite salts.

Boiling point—The temperature at which a liquid boils at a specified pressure.

Booster—A laundry aid available in granular or liquid form that is formulated to reinforce specific performance characteristics desirable in laundering.

Buffer*—A compound or mixture that, when contained in a solution, causes the solution to resist change in pH. Each buffer has a characteristic limited range of pH over which it is effective.

Builder—A material that enhances or maintains the cleaning efficiency of the surfactant in a detergent formulation. The part of a formulation that imparts alkalinity, buffering, corrosion resistance, etc.; generally the non-surfactant portion of a cleaner. Builders eliminate precipitation of minerals in hard water by chelating salts while keeping them suspended, or by ion exchange.

CHEMTREC—Chemical Transportation Emergency Center; a national center established by the Chemical Manufacturers Association (CMA) [currently the American Chemistry Council] to relay pertinent emergency information concerning specific chemicals on requests from individuals. CHEMTREC has a 24-hour toll-free telephone number, (800) 424-9300, to help respond to chemical transportation emergencies.

CO—Carbon monoxide; a colorless, odorless, flammable, and very toxic gas produced by the incomplete combustion of carbon. It is also a byproduct of many chemical processes.

CO2Carbon dioxide; a heavy, colorless gas which is produced by the combustion and decomposition of organic substances and as a byproduct of many chemical processes.

Detergent—Any cleaning agent. In popular usage, washing and cleaning agents with a composition other than soap that clean by much the same mechanisms as does soap. The term detergent is used to describe both the basic surface-active agents and finished products. Based on a surface-active agent that finished products are synthesized from chemically, a variety of raw materials derived from petroleum, fatty acids, and other sources. They may also contain ingredients such as builders, anti-redeposition agents (CMC), corrosion inhibitors (EDTA), suds control agents (defoamers), fluorescent whitening agents (optical brighteners), sodium sulfate (processing aids), water, alcohols, hydrotropes, colorants, fragrances, and pacifiers.
