Detergency
DABEER OFFERS A WIDE RANGE OF SPECIALIZED SEQUESTERING AGENTS FOR USE IN HOUSEHOLD DETERGENCY AND I&I.
Hard water and the presence of heavy metals cause precipitates, color change and rancidification in detergents, together with loss of bleaching efficiency due to breakdown of bleaching agents caused by reaction with trace metals. The application of DABEERSEN sequestering agents prevents these problems, making the cleaners work at their maximum capacity.
Household detergents: Traditionally, laundry detergents contained high concentrations of polyphosphates. However, due to the negative effect they have on the environment (causing water eutrophication) they have been replaced by various components: zeolites, enzymes, polyacrylates and chelating agents. Chelates help to avoid the precipitation of magnesium and calcium salts and they inhibit the decomposition of bleaching agents (sodium perborates, PBS) which is catalyzed by the presence of trace metals.
Institutional detergency (I&I): Industrial and institutional detergents are usually composed of a great amount of soda as a degreasing substance and a chelating substance, such as DABEERSEN Na4 40% L (tetrasodium EDTA salt) to prevent magnesium salt and calcium precipitation deposits on glass which gives it a whitish and dull appearance.
The application of DABEERSEN 503 delays the hydrolysis of polyphosphates, making them more stable at high temperatures even in the presence of traces of iron.
