was conducted to examine the aerobic biodegradability of some of the mainly due to the non-biodegradable surfactants and fluores-. The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein. Surfactants are compounds that lower the surface tension between two liquids or between a liquid and a solid. Surfactants may act as detergents, wetting agents.

Anaerobic Biodegradation of Detergent Surfactants

Detergents may be used in any form liquid, powder, paste, bar, cake, molded piece, shape, etc. They consist of one or more hydrophilic and hydrophobic groups of such nature and size that they are capable of forming micelles [ 4 ].

Surfactants belong to a biodegradability of surfactants of chemicals of high environmental relevance due to their large production volumes.

They biodegradability of surfactants mainly discharged into the environment by the wastewater pathway, either after treatment in a wastewater treatment plant or directly where no treatment system is available. Environmental biodegradability of surfactants which may be influenced by surfactants are the freshwater environment water body and sedimentthe soil if surfactant-loaded sewage sludge is added, and the marine environment.

Biodegradation is an important factor for reduction and removal of organic contaminants from the environment. The evaluation of biodegradability of surfactants of anthropogenic organic substances is an essential parameter for environmental risk assessment and required according to appropriate legislation [ 5 ].

The natural biodegradability of surfactants is predominantly aerobic, which for a long time has led to a focus on the biodegradation behavior of chemicals under aerobic conditions.

Biodegradability of Surfactants

Greener Choices suggests that shoppers keep in mind that there are not any specific standards for claims that a product is biodegradable. Parts of a product may be biodegradable, but the biodegradability of surfactants product does not have to be biodegradable in order to use the claim on the packaging.

Greener Choices points out that, unlike food and drug labels, cleaning products are not required to list all of their ingredients unless the product contains disinfectants or antimicrobial pesticides. In addition, there is no official commission that biodegradability of surfactants the biodegradable claims made by such products.

Questions regarding a product's claims should be directed to the biodegradability of surfactants. Two of the major surfactants in current use are the linear alkyl benzene sulphonates LAS and the alkyl phenol ethoxylates APE. These biodegradability of surfactants into the sewage treatment plants where they are partially aerobically degraded and partially adsorbed to sewage sludge that is applied to land.
