What do the terms "synthetic" and "natural" really mean? Consumers and end users should be wary of the term "natural" when used to describe cleaning products. All of the chemicals used to make the ingredients that go into cleaning products are found in nature. Very few chemicals extracted from plants or the earth are used without further processing to obtain ingredients that perform a cleaning function. Thus, the term "natural" to describe a final product can be misleading. For example, claims for "natural" cleaners usually refer to the surfactant, the product's primary cleaning ingredient. Almost all the products used for personal cleansing, laundering, dishwashing and household cleaning are surfactant-based. Surfactants are chemicals that reduce the surface tension of water, so the water can quickly wet a surface and soil can be loosened and removed. Surfactants are made from petrochemicals (derived from crude oil or natural gas) or oleochemicals (derived from fats and oils). Some types of surfactants can be made from either raw material source. Petrochemicals are often termed "synthetic" materials, while oleochemicals are sometimes called "natural." Both have "natural" sources, since crude oil is extracted from the earth and oleochemicals come from plants or animals. Whatever their source, surfactant raw materials have to be chemically converted, or synthesized, before they can become useful ingredients in cleaning products. In its final form, a surfactant based on oleochemicals is similar to the same surfactant based on petrochemicals. This similarity enables manufacturers to use either or both types of surfactants in their cleaning products. Availability, cost, ease of formulation, and desired product form and characteristics are the deciding factors. Source: The Soap and Detergent Association. www.cleaning101.com
