Abstract
The present invention discloses a method for cleaning a substrate comprising contacting the substrate in a cleaning cycle with an aqueous cleaning solution comprising an aqueous diluent and a detergent composition, the detergent composition comprising a glycolic and/or lactic acid oligomer with an average degree of polymerization between 1.8 and 6. The glycolic and/or lactic acid oligomer provides a controlled release of glycolic and/or lactic acid in the cleaning solution generating an acidic pH gradient in the cleaning solution during the cleaning cycle. Preferably, the substrate is contacted in a rinse cycle with an aqueous rinse which is substantially free of an intentionally added rinse agent or fabric softener.
Description
The present invention relates to neutral extremely alkaline cleaning applications, the field of particularly in automatic washing machine, cleaning.
In the clean cycle of automatic washing machine, base material, for example bowl dish or send laundry for washing circulates through the detergent solution that surrounds this base material and cleans.This detergent solution is to obtain through cleaning composition in water, washing composition can comprise various ingredients for example alkaline agent, washing assistant, SYNTHETIC OPTICAL WHITNER, enzyme, be used for froth breaking or clean Surface promoting agent, polymkeric substance, corrosion inhibitor etc.Coml machine cleaning detergent is known to be under alkaline pH, to operate, and makes that the effectiveness of their removal incrustation scales and soap scum silica frost is not high.Between the strong usage period, scale crust can be deposited in the inwall of automatic washing machine.In addition, after the cleaning on some base material visible precipitation of scales.
Representational is the rinse step that in wash dishes, is provided with independent use rinse aid compsn, and it is used to prevent that these hard water throw outs from gathering and/or with its removal.The rinse aid compsn helps the component of moistening base material when further typically being included in rinsing, for example nonionogenic tenside and/or hydrotropic solvent, and other improves the additive of the effectiveness of rinse cycle, for example polymkeric substance, siloxanes etc. sometimes.These rinse aid compsns are not to be designed for the purpose that realizes that main dirt is removed, and can in the machine rinse cycle, add dividually mutually with the detergent composition that in main clean cycle, uses.Strengthen the ability of rinsing and can prevent that particularly the ability that stain and incrustation scale form from being generally measuring of rinse aid performance.
Handle and Dose Problem for the product and the elimination washing composition of providing convenience to the human consumer, the mfr has made and has comprised at least a washing composition and the wash dishes tablet of rinse aid function in a slice.Such tablet is sometimes referred to as 2 and closes 1 tablet or as the tablet of rinse-added auxiliary agent in having.
Some 2 close 1 tablet and have the wax part that comprises rinse aid.There is shortcoming in the tablet of this type owing to only having in being no more than 55 ℃ clean cycle, to use, and will dissolve fully in surpassing 55 ℃ clean cycle because comprise the wax part of rinse aid.This causes whole rinse aids before the rinse cycle of reality, in dish-washing machine, to be exhausted.In addition, such 2 to close 1 tablet manufacturing extremely complicated and expensive.
The known tablet of other type is that pH susceptibility 2 is closed 1 tablet.The tablet of this type has the rinse aid part that is included in the pH sensitive material.This pH susceptibility 2 is closed 1 tablet and can in surpassing 55 ℃ clean cycle, be used.
US2001031714 relates to laundry, dishwashing detergent or the cleaning detergent part with two kinds or more kinds of stain remover components; Wherein at least two kinds of time points in different laundries, dishwashing detergent or cleaning course are released in the washing lotion; Said part comprises at least a release control (physics) chemical switch (switch); It does not receive or not exclusively receives temperature to control, and also includes the material that one or more increase the scope of pH variation.Be released in the such component in the liquid separately in the latter half of this cleaning procedure; In addition pH changes the susceptibility dressing; Compounding goes into to use in the stain remover preparation of pH sensitive adhesive, or compounding goes into to use pH to change in the stain remover preparation of susceptibility substrate material.
Now; Contriver of the present invention has been found that in the clean cycle in automatic washing machine from having mean polymerisation degree 1.8 to 6, and the sustained release of the acid of the oligopolymer of preferred 1.8 to 4 hydroxyethanoic acid and/or lactic acid can advantageously be eliminated the needs that the dosage at the rinse aid that separates of rinse cycle adds.
Therefore; In first aspect; The invention discloses the method that is used for cleaned base material; Be included in base material is contacted with aqueous cleaning solution, said aqueous cleaning solution comprises aqueous diluent and detergent composition, and this detergent composition comprises that to have mean polymerisation degree be 1.8 to 6 hydroxyethanoic acid and/or lactic acid oligomer.
This base material preferably contacts with the water-based purificant in rinse cycle then, and wherein the water-based purificant is substantially devoid of the purificant of having a mind to interpolation.
Hydroxyethanoic acid described herein and/or lactic acid oligomer are water-insoluble and are biodegradable.Oligopolymer is to contact afterreaction with water, and promptly water makes the polyester of ester linkage hydrolyzing.The use that has been found that the oligopolymer of this type polymerization degree that has in this scope can provide water-soluble hydroxyethanoic acid and/or lactic acid in the clean cycle cleaning soln sustained release and be created in the pH gradient in the clean cycle thus.
By this mode; The alkalis component possibly suitably brought into play its cleaning function in the starting stage of clean cycle; Because the use of hydroxyethanoic acid and/or lactic acid oligomer can be guaranteed hydroxyethanoic acid and/or lactic acid and slowly discharge, to such an extent as to mainly bring into play its function at the subsequent stage of this technology.
Hydroxyethanoic acid and/or the lactic acid sustained release in clean cycle has advantageously been got rid of the needs that are metered into rinse aid separately in the rinse cycle after clean cycle, or the needs of the fabric softener that separates.Therefore, the water-based purificant is substantially free of the rinse aid or the fabric softener of having a mind to interpolation.Preferably showing no sign of rinse aid or fabric softener is added in this water-based purificant wittingly.
The sustained release of the acid in clean cycle reduces or prevents that hard water (calcium and magnesium salts) is deposited in the washing machine and/or the formation on the base material that is cleaned, and gets rid of the needs that use washing machine sanitising agent separately thus.The sustained release of acid also impels removing of soap scum silica frost.
In laundry applications, the mineral scale of formation is present on the clothes.This incrustation scale is formed by the non-water-soluble calcium of lipid acid and the silicate and the zeolite of magnesium salts, carbonate and less scope basically.These depositions on clothing generally be the light grey dyeing of visible with or even because the more stain that the viscosity of mineral scale causes, dirt causes outward appearance beastly and is deleterious to " soft feel " of clothing.The sustained release of acid has the bating effect on fabric and is of value to more secular lasting fragrance, is because it is provided at the tackiness of the spices that improves on the clothing.
