Primary degradation occurs when the molecule has been oxidized, or otherwise altered by bacterial action to such an extent that its characteristic properties are no longer evident or when it no longer responds to analytical procedures more or less specific for detecting the original surfactant. 3, record 1, English, - primary%20biodegradation
Record number: 1, Textual support number: 2 CONT
In relation to surfactant biodegradability, it is important to distinguish between primary and ultimate biodegradation. For example, the loss of the ester sulphate groups from surfactants such as sodium dodecyl sulphate or sodium dodecyltriethoxy sulphate would be a primary biodegradation step that would lead to an immediate loss of susfactant properties. ... For the most part, industry and water and sewage authorities have been content to ensure that new surfactant products do undergo reasonably rapid primary and ultimate biodegradation and a variety of laboratory tests have been developed specifically since the advent of synthetic surfactants. 4, record 1, English, - primary%20biodegradation

La biodégradation primaire est [...] dite « primaire » parce qu'il s'agit de la première phase du processus de biodégradation [des] composants [des détergents]. Cette première phase correspond à la disparition des propriétés tensioactives, ce qui élimine simultanément la toxicité du composant. 1, record 1, French, - biod%C3%A9gradation%20primaire
