Abstract

A non-phosphate detergent for fabrics is prepared from ordinary surfactant, fibre penetrant, biologic enzyme chosen from proteinase, lipase, amylase and cellulase, low-temp bleaching agent and assistant. It is characterized by its 4 soil-removing steps at different time intervals by different components, resulting in higher detergency and less water consumption.

Description

A kind of without phosphorus fabric detergent with sequential quadruple detersive power

The present invention relates to a kind of without phosphorus fabric detergent of sequential quadruple detersive power, belong to daily chemical product.

Along with progress, the development of science and technology of society, people more and more notice clean to health () importance as its name suggests: escort defendance life.Here be stressed that especially that " cleaning " is not equal to health.The implication of health is that cleaning helps health, the clean disease that reduces, that is to say to help cleaning healthy, that do not cause disease, is only health.The development history of synthetic detergent, people are to the history of health with the distillation of clean relation understanding just.Nineteen forty-six is that the tensio-active agent of representative is the washing powder of major ingredient with the tetrapropylene alkyl benzene sulphonate (ABS), replaces soap market at one stroke, and this is a first-generation synthetic detergent powder.Arrived the fifties, it is found that the foam in the washes of first-generation washing powder is difficult for degraded, polluted rivers and lakes, caused that water body COD and BOD continue to descend, developed country such as dolantin has just forbidden the production and selling of first-generation washing powder with the state's laws form soon.What replace is to be the phosphorous washing powder of main auxiliary agent (active ingredient) with (gathering) phosphoric acid salt.To the sixties it is found that " phosphorus " in the phosphorous washing powder, be very effectively " phosphate fertilizer ", can make the water quality eutrophication, impel lower plant overgrowing such as algae, water volume flow rate slows down, and COD and BOD descend, marine animal death such as water quality fouling fishes and shrimps, this is that so-called red (red) tide takes place frequently, and has caused serious disturbed ecological balance, after water system degenerates, water resources is by havoc, to cause people and animals' drinking-water to seriously influence, therefore, s-generation washing powder also is antihygienic.From the sixties, developed countries is just forbidden the production and selling of phosphorous washing powder with the state's laws form.Except drugs, also have what industrial goods to be forbidden production and selling with the state's laws form? it is exactly phosphorus-containing detergent.Non-phosphide detergent has been a third generation washing powder, people are when research third generation non-phosphide detergent, attention is all concentrated in the detersive power raising of no phosphorus powder, the consumption and the kind of tensio-active agent have been strengthened, seek New-type adjuvant, and ignored " white mass " health hazard residual when washing the black dirt off.There is the eighties people to invent APG (APG) and is the skin mild tensio-active agent of representative, see patent such as JP9627481, WO9601306 for details.There are many experts to think LD ₅₀Do not investigate the washing composition residue to human body skin toxicity, when this just proves absolutely the washing composition development course, be also noted that the development of synthetic detergent technology.Current, long-acting biological zymotechnic and low-temperature safety bleaching technology are two big focuses of synthetic detergent technology.The raising of former detersive power mainly develops at different dirt compositions and adopts different Substrates respectively by wetting, emulsification, dissolving and in the effect of the mechanical force scrubbing of going down, especially biological enzyme is the major contribution of biotechnology to the conventional washing industry to the washing technology of dirts such as albumen, grease, fiber.The bleaching technology of low-temperature safety was that the pigment washing technology that is based upon on the energy-saving and water-saving safety and Health basis is the another focus of synthesis of detergent technical development afterwards.We in synthetic study in synthetic detergent development course and new and high technology the pushing factor to the synthetic detergent development; invented the without phosphorus fabric detergent of washing that has environmental protection, protects the sequential quadruple scrubbing of skin energy-saving and water-saving according to green parallel type research of modern times thinking; can make powder to it, also can make tablet.The latter is developing direction especially, and the without phosphorus fabric detergent of washing is made tablet and reduced volume, has made things convenient for the storage transportation, has improved the accuracy of consumption.This tablet is different from soap, because its entry is instant, has the easy-to-use advantage of washing powder equally.On the basis of above research thinking, we have carried out a large amount of experiments with the slow controlled release production technology in orthogonal test and the pharmaceutical technology, have finished the present invention.
