Polymeric builders in the form of anionic polycarboxylates based on acrylic acid account for more than 90% of all polymers used in detergents. A.I.S.E. Interactions of Polycarboxylates with Major Inorganic Soil Components \/ Jean-Marie Sequaris -- 8. Significance of Polycarboxylates in Detergents \/ Dieter Kiessling -- 6. 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.

The wealth of literature deals with mechanistic aspects of the mode of action of polycarbox-ylates in the washing process. Previous Post TR 054 – Assessment of the Biodegradation of Chemicals in the Marine Environment Next Post TR 056 – Aquatic Toxicity Data Evaluation. In March 2008, the Commission mandated SCHER to produce an updated scientific opinion and to comment whether it agreed with the main conclusion of the HERA report on polycarboxylates in detergents[18], i.e. endobj POLYCARBOXYLATES Polycarboxylates, also known as polyacrylates, are polymers having a carbon–carbon backbone with attached carboxyl groups. Polycarboxylates are polymers based on acrylic acid or maleic acid, with both homopolymers and copolymers being required by the LHCP industry. They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid. Zeolites in detergent production. Deposition effects on fabric are compared with threshold inhibition effects and calcium binding capacities of the polymers. Liquid Laundry Detergents over Powdered Detergents 9. Eco friendly soaps and detergents 2. Advantages - Maintain the flowability of concrete for a long time The presence of high levels of surfactants is a major complication, due to the strong tendency of surfactants to form micelles and to interact with the polymers. Les lessives dites écologiques pour le linge envahissent le marché et sous toutes les formes : liquides, en poudre, tablettes, etc. EPA Safer Choice Certified.

The use of polycarboxylates in detergents only began to play a major role in the early 1980s. 2. The polycarboxylates obtained thereby have a more homogeneous distribution of … They have a pronounced dispersing capacity for particulate soil and sparingly soluble salts such as calcium carbonate and thus they are able to counteract incrustation and redeposition of soil onto fabrics. polycarboxylates in detergents, US $ 900 - 1200 / Ton, 5 days.Source from Beijing Dongke United Technologies Co., Ltd. on Alibaba.com. polycarboxylates automatic dishwashing dishwashing detergents automatic dishwasher Prior art date 1995-10-27 Legal status (The legal status is an assumption and is not a legal conclusion. Ever made. These polycarboxylates of the prior art were discloses for use in laundry detergents, and no suggestion exists in either reference that they might provide the required suppression of filming and spotting on glassware when they are used in ADD compositions. In Germany, a total of 14,900 t of polycarboxylates was consumed in 2008 predominantly as co-builders in detergents where they played a key role in the development of phosphate-free detergents. that the use of polycarboxylates in detergents does not pose risks for environmental compartments with the exception of the soil local compartment for P-AA/MA (a … Hydrophobically-modified polycarboxylates and process for their preparation: 1991-11-19: Leighton et al. The packaging of detergents must indicate the content, in accordance with the specifications provided for these substances, and indicate instructions for use and special precautions, if required. 1 0 obj Generally, zeolites possess a number of advantages over other builders during the production of deter- gents. Polycarboxylates are used as builders in detergents. polycarboxylates in detergents, US $ 900 - 1200 / Ton, 5 days.Source from Beijing Dongke United Technologies Co., Ltd. on Alibaba.com. endobj %���� Disadvantage of the method described in this paper compared to the former investigation is the low recovery (<10%) of methylated monomers. Polycarboxylate ethers (PCE) are used as superplasticizers in concrete production. In Germany, a total of 14,900 t of polycarboxylates was consumed in 2008 predominantly as co-builders in detergents where they played a key role in the development of phosphate-free detergents. Recent developments in polymer builders and specialty polymers (i.e., soil shield and soil release agents, dye transfer inhibitors) for detergents are reviewed. The outcome of this present environmental risk assessment provides a sound basis for the conclusion that the use of homopolymers in detergent products does not pose a risk to the environment.” This conclusion is applied to 16 polycarboxylates currently being used in cleaning products that were evaluated by the HERA program (Table 1a).
