Abstract

POSTUPAK ZA DOBIJANJE TEČNOG DETERDŽENTA, koji obuhvata reakciju smese površinski aktivnih sredstava, vode i dovoljne količine rastvorenog elektrolita radi obrazovanja fizičke strukture u kojoj je površinski aktivno sredstvo ograničeno prisustvom elektrolita radi obrazovanja sferulata od kojih svaki ima više koncentričnih ljuski od površinski aktivnog sredstva i vode, na značen time, što se vodenom micelarnom rastvoru ili emulziji koji sadrže od 9 do 30 procenata anjonskog, nejonskog ili mešovitih anjonskih i nejonskih površinski aktivnih sredstava dodaju funkcionalni elektroliti kao poboljšivači, u cilju obrazovanja sferularnog sistema, što se zatim vrši centrifugisanje pri 800 G na 25 stepeni celzijusa u toku 17 časova, odnosno pri 20000 G na 25 stepeni celzijusa u toku 5 do 90 minuta pri čemu odnos elektrolita u najmanje jednoj preovladavajuće vodenoj fazi obezbeduje koncentraciju od 1,2 do 4,5 gram jona na decimetar kubni alkalnog metala, zemnoalkalnog metala i/ili amonijum katjona, što odgovara minimalnim i maksimalnim koncentracijama na kojima je deterdžent još stabilan pri stajanju na 40 stepeni celzijusa, što se zatim suspenduju čvrste čestice poboljšivača u odnosu na površinski aktivno sredstvo od 1,2:1 do 4:1, i u količini od 15-20 mas.% po masi aktivnog sastojka ili sastojaka u formulaciji čime se dobijaju sferulati kao flokule za ispunu prostora, pri čemu je granica tečenja deterdženta od 15-30 Nm(na minus drugi stepen), a viskoznost na 136 sm(na minus prvi stepen) smicanja je tipično izmedu 0,1 i 2 Pa.s. Prijava sadrži još 2 zavisna zahteva.PROCESS FOR OBTAINING LIQUID DETERGENT, comprising reacting a mixture of surfactants, water and a sufficient amount of dissolved electrolyte to form a physical structure in which the surfactant is limited by the presence of electrolytes to form spherulates each having more concentric shells than surfactant and water, in that aqueous micellar solution or emulsion containing from 9 to 30 percent of anionic, nonionic or mixed anionic and nonionic surfactants is added functional electrolytes as enhancers, in order to form a spherical system, which is then centrifuged at 800 G at 25 degrees Celsius for 17 hours, or at 20,000 G at 25 degrees Celsius for 5 to 90 minutes, where the electrolyte ratio in at least one predominantly aqueous phase provides a concentration of 1.2 to 4.5 grams of ions per cubic decimeter of alkali metal, alkaline earth metal and / or ammonium cation , which corresponds to the minimum and maximum concentrations at which the detergent is still stable when standing at 40 degrees Celsius, which then suspends the solid particles of the improver in relation to the surfactant from 1.2: 1 to 4: 1, and in an amount of 15-20 wt.% by weight of the active ingredient or ingredients in the formulation to give spherulates as flocs to fill the space, with a detergent flow limit of 15-30 Nm (minus the second degree) and a viscosity of 136 cm (minus the first degree) the shear is typically between 0.1 and 2 Pa.s. The application contains 2 more dependent requests.
