Description

Isotropic liquid detergent comprising soil release polymer

Technical field

The present invention relates to isotropic liquid detergent composition, its comprising water, hydrotropic agent, anionic sulphonate or Sulfate surfactant and polyester base soil release polymer.

Background technology

WO09153184 propose it is a kind of can be by using the mixture replacing selected from polymer and the more effective composition of enzyme Surfactant and the laundry detergent liquid concentrate designed.A kind of preferred composition uses the polyethyleneimine of ethoxylation The combination of amine (EPEI) and polyester soil release polymers (SRP), with the significantly lower washing of delivering more usual than high-performance liquid The excellent greasy dirt of surfactant level acquisition and particulate stain removal.Exemplary composition includes anion surfactant simultaneously And further comprise that, by the soaps in sodium hydroxide with aliphatic acid formation, the anion surfactant includes and uses hydroxide The linear alkylbenzene sulfonate (LAS) that sodium is neutralized.Said composition is alkaline.It has been found that the SRP for embodiment have passed through alkaline water Solution, and the basic hydrolysis using triethanolamine (TEA) by being catalyzed in the composition.

A kind of obvious solution of SRP hydrolytically unstable sex chromosome mosaicism is to separate said composition, and by its It is stored in single room, so that SRP is not contacted with TEA or alkaline matter.It is this to be probably based on sour certain formulations Based on the teaching in EP294893, US2010229313 and US3893929.However, using separated composition be it is undesirable, Because it can increase cost and complexity.Consumer wishes to deliver all cleaning substances from single main cleaning solution.

Main cleaning solution is configured to acidity and there is sizable technology prejudice.Generally believe that they can produce acidic cleaning bar Part, it is reduced due to the performance of surfactant system and some possible enzymes, and cleaning will be caused insufficient.US5290475 (Colgate) it is a document, it in order to improve SRP stability to preparing show technology prejudice in acid condition. Liquid softens and antistatic nonionic detergent composition includes nonionic detergent, the anionic detergent as main component Agent, cationic fabric softener-antistatic additive and polyethylene terephthalate-polyoxyethylene terephthalate type Water-soluble portion decontamination promote polymer.In order to help detergent and Optical Bleaching Agent that may be present in liquid detergent Dissolving, generally include the alkaline matter of small scale or the mixture of such material.Suitable alkaline matter include it is single-, Two-and three-alkanolamine, alkylamine, ammonium hydroxide and alkali metal hydroxide.Wherein, material preferably is alkanolamine, preferably Three alkanolamines, wherein particularly preferred triethanolamine.During the pH of final liquid detergent comprising this alkaline matter generally will be Property or it is slightly alkaline.Satisfactorily pH scopes are 7 to 10, preferably from about 7.5 to 9.5.

The pH that WO9742286 (P＆G) teaches laundry detergent in page 3 and generally had is more than 7.5.Contained according to page 9 There is SRP composition, it discloses when being measured as 10% aqueous solution, the pH with about 7.2 to about 8.9.

US4785060 (Colgate) discloses the PET POET of the HMW prepared using hybrid catalyst system SRP.It is said that these SRP are in the suds in the presence of builder keeps their performance at a high ph.Wrapped according to them are instructed It is contained in both solid and liquid detergent composition.The disclosure of which, which is taught, minimizes included alkanolamine such as TEA With ionizable salt such as Na.It teaches in the row of the 10th column the 13rd to 15, it is preferable that be generally used for improving liquid detergent mixing Nertralizer used in thing pH is sodium hydroxide.In the 17th to 18 row, its continue to instruct " should generally avoid triethanolamine salt and Free triethanolamine ".PH scopes will be 6 to 10, preferably 6.1 to 8.9, generally more preferably 6.5 to 7.5.

US4759876 (Colgate) discloses the decontamination comprising SRP and promotes liquid detergent composition.The composition Further comprise the enzyme stabilizers for stablizing ratio, it also functions as the buffer of liquid detergent composition pH is maintained at into a certain Neutrality or slightly acid range, to stablize SRP and fluorescent whitening agent.It is said that said composition " is kept substantially " its dirt in storage Hydrolyze fluorescent brightening and decontamination promotes characteristic, brighten and handle so that the clothing washed with it is cleaned effectively.However, coming from The US5110506 of same assignee shows that performance is good not as ' 876 are proposed.It is also clear that according to ' 876 disclosure, In storage, pH turns to acid.We determined that this may should be attributed to SRP decomposition because its in storage more than just hydrolyzing January. Do not include any soaps.It is said that enzyme stabilizers/the buffer can keep pH 6.2 or higher.The pH provided after storage Scope is 6.2 to 6.5.However, it is 5.8 to 7 to also give the pH scopes that will not further make the polymer unstable.

In US5110506 (Colgate), except disclosing the detergency ability difference that ' 876 liquid is obtained after storage Outside, it is specific very expensive it also teaches minimize 2EO and 3EO contents by the way that the nonionic is changed over Material can obtain the small improvement of the detergency ability after storage.The liquid with pH in the range of 7.3 to 8.1 is taught to wash Wash agent.This shows that pH still can change due to hydrolysis.It is probably due to being converted to more effective type that the cleaning claimed, which improves, Nonionic surfactant.

GB1466639 (P＆G) discloses the surfactant neutralized with monoethanolamine and SRP detergent liquid.Including Some free TEA are so that washings keep alkalescence.Disclose two distinct types of liquid.In the first type, selection Specific nonionic surfactant assigns composition enough physical stabilities.In second of type, aliphatic acid (soap is included Class) to provide extended storage stability.The embodiment of seemingly second of the type of composition of embodiment 1.It includes 1.5% oil Sour TEA salt and 5% SRP (coming from table 1).It was found that it is alkaline compositions.

US4411831 (Purex) discloses a kind of aqueous detergent composition of stabilization, and it has enhanced decontamination property And be substantially made up of SRP (there is LAS) and nonionic and buffer, the buffer keeps the waterborne compositions enough PH in 5.0 to 9.0, preferably 6.5 to 7.5.Embodiment is being adjusted to 7 main washing group comprising LAS and nonionic and pH Zelcon4780SRP has been used in compound.Hydrotropic agent is used as using SXS.TEA or soap are not used in this embodiment Class.The disclosure of which teaches the comparative example liquid without buffer and produces acid pH in storage.It is said that acid pH is to brightening Agent is harmful to.We have appreciated that acid pH, which is due to SRP, decomposes what is produced.Add buffer to stablize pH to the solution used.Due to PH is more alkaline, and this will cause SRP to decompose increase.Brightening agent can be protected, the true purpose of this seemingly invention.Institute The suitable buffer of teaching includes bicarbonate, orthophosphates, borate and alkanolamine hydrochlorate.

US4713194 (P＆G) discusses the readily degradable of the SRP in alkaline environment, and if proposed in particulate composition Middle use then is protected by coating (enrobing) to SRP, or by product if being used in fluid composition PH is adjusted to 7.0 to 8.5.Embodiment includes the fatty acid distribution of coconut oil of high content.

US6262007 (P＆G) describes acid detergent liquid, and it includes SRP to reduce with viscosity during temperature drop Increase.Some embodiments include TEA, but not including that hydrotropic agent or aliphatic acid.

The concentrated liquid detergent composition for including SRP is needed, it even all provides excellent clear after extension storage Clean property.
