Abstract. Detergents are used in cleaning household surfaces, dishes and washing laundry. For detergents, synthetic zeolite grades have been developed to fulfil the role of the product “builder”. Defunkify Laundry Detergents are the highest performing and safest detergents. Polycarboxylate additives suitable for use in automatic dishwasher detergent compositions are prepared by polymerizing three or more monomers including monoethylenically unsaturated C 3 to C 6 monocarboxylic acids such as acrylic acid, monoethylenically unsaturated C 4 to C 6 dicarboxylic acids such as maleic acid, and monoethylenically unsaturated esters of acrylic or methacrylic acid. �u��hٹ-���)��EW�� ��0Z���)�ק�}XJ�X��wI8����t�ň�nr1g>��5+͇�}jй��r�������2G7Eޗ{��th��#?�wY�X��P�Se��2J�A�]l�wo�����pc!N֤a(��#y!�[�M/dC�$_��\*/����K�ҕ��\v=���6�8�n� S,��L��,�W�[�@���[!p� ��j��0�:��z _�p c����I�բd%��Z�Bv�m�p�� >�L5�dE�Oe;�~$�ĿjMΦw�>�x�Ӌ��~��B�jK�f1[�ąR�@�e�K�]+V���K"�D[�_����b(�W�jt[�Y�T��A�.8����n Fabricant brésilien de détergent.

As the generic name of the HERA report is “Polycarboxylates used in detergents” the committee suggests, for the purpose of increasing the clarity, to include a short description of the term polycarboxylates and of which chemical families are used in detergent formulations and related products. Some of these can include sodium carbonate, polycarboxylates, and also zeolites. Apart from this, polymers help in part replacement of builders like STPP and also inhibit unwanted hydrolysis which results in loss of active substance. The polycarboxylates also may be used as anti-redeposition agents in detergents. Polycarboxylate ethers (PCE) are used as superplasticizers in concrete production. Polymeric electrolytes, especially polycarboxylates, are also widely recognized as effective detergent builders as indicated in literature,,. endobj Polycarboxylates are used as builders in detergents. The polycarboxylates also may be used as anti-redeposition agents in detergents. In addition to the surfactant modern detergent formulations contain a number of other substances to improve the detergency, to bleach, to lessen redeposition of dirt, to brighten, or simply to reduce the cost of the formulation.
