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

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

Limited ultimate biodegradability in aerobic tests for ready biodegradability(i. e. below pass level) due to sorption, toxicity or other inherent properties that preclude sufficient biodegradability under standard test conditions, provided that other convincing scientific evidence is available to demonstrate that the substance can be degraded to harmless products in the aquatic environment(70% within 28 days).  2, record 3, English, - ultimate%20biodegradability

In the past, the key aim of EU detergents policy was to safeguard the single market in these products and to ensure a high level of environmental protection. It focused on preventing foam in water systems caused by surfactants, a key substance used in detergents. In its working document, the Enterprise Directorate-General suggests the recasting of the five existing Directives concerning the biodegradability of surfactants. New provisions are included to better protect the aquatic environment by controlling the ultimate biodegradability of detergents;...  3, record 3, English, - ultimate%20biodegradability

[...] il existe une discordance entre ce que prévoit le texte concernant la biodégradabilité et les modalités pour la mesurer qui sont énoncées dans l'annexe technique.

De nouvelles dispositions ont été incluses en vue d'améliorer la protection des systèmes aquatiques : les méthodes d'essais sont désormais plus strictes et portent sur la biodégradabilité finale et non plus initiale. Le champ d'application a également été élargi à tous les types de détergents tensio-actifs, alors que jusque-là ceux contenus dans les assouplissants textiles et les produits pour lave-vaisselle -soit environ 10 % du total- étaient exclus faute de consensus sur la méthode de test.  3, record 3, French, - biod%C3%A9gradabilit%C3%A9%20finale
