Description

Improvement about laundry cleaning compositions

Technical field

The present invention relates to comprise the laundry cleaning compositions (laundry cleaning compositions) of cationic surfactant.

Background technology

The laundry detergent product is characterised in that and has washing assistant, enzyme, fluorescent agent (fluorescer) perfume compound (perfume), antiredeposition polymkeric substance, soil release polymer, source of alkalinity (source ofalkalinity), is not used in the sequestrant (chelating agents other than forhardness ions) of hardness ions and in SYNTHETIC OPTICAL WHITNER or its precursor one or more.

These composition also comprises surfactants.The general exemplary surfactants of using comprises aniorfic surfactant and nonionic surface active agent.Aniorfic surfactant generally is through oversulfated or Sulfonated material.For example, linear alkylbenzene sulfonate (LAS) is the aniorfic surfactant type that is widely used.Nonionic surface active agent generally is the material through ethoxylation.Less use other surfactant types.The effect of these tensio-active agents is to help to remove spot and keep spot to be in suspended state from textile article, thereby can spot be separated with goods by flushing.

Main human consumer misgivings relevant with the laundry product prescription are stench (malodour).Malodorous a kind of possible source is bacterial activity (although having some kinds of other sources).It is believed that, towards lower wash temperature, the increase, lower water loss of use of washing composition (for example protecting toner end or liquid washing agent) that do not contain SYNTHETIC OPTICAL WHITNER and the trend of shorter washing time, cause the more substantial bacterium that withstands laundry processes with comparing under previous general " boil and wash (boil-wash) " condition.

Cationic surfactant is the tensio-active agent of wide region, and it is used as textile softener, hair conditioner, biocide, static inhibitor, corrosion inhibitor and emulsifying agent.The recommended detergent composition that is used for of cationic biocide material is as reducing malodorous means.These materials have the quaternary ammonium compound of blended long-chain and short-chain alkyl chain typically, and can comprise aryl or alkyl-aromatic yl group.The well known examples of this class material is benzalkonium chloride (benzalkonium chloride) (alkyl dimethyl benzyl ammonium chloride).Benzalkonium chloride is the mixture with alkyl benzyl dimethyl ammonium chloride of different alkyl chain length.Maximum antimicrobial acivity is considered to relevant with the C12-C14 alkyl derivative.For a long time, think that the biocidal activity of cationic surfactant takes place by the complex mechanism that may further comprise the steps: (i) be adsorbed onto on the bacterial cell surface; (ii) diffuse through cell walls; (iii) combine with cytoplasmic membrane, (iv) cytoplasmic membrane breaks; (v) tenuigenin composition seepage; (vi) cytolysis causes necrocytosis.

The also recommended washing (-)off properties that is used to improve the laundry detergent product of cationic surfactant material.The recommended typical cationic surfactant that is used for this purposes is fatty dimethyl hydroxyl ethyl or fatty leptodactyline.EP0008829 discloses the cationic surfactant that uses wide region, comprises C12-14 alkyl methyl dihydroxy ethyl ammonium chloride and tallow alkyl trimethyl ammonium chloride.US2004/058835 discloses wherein, and aliphatic chain is methyl/dihydroxy ethyl, dimethyl/hydroxyethyl or the trimethyl quaternary ammonium salt of C8-18 alkyl.The suitable example of these materials is Praepagen Hy ^TM(fatty alkyl dimethyl hydroxyl-ethyl ammonium chloride, ex Clariant) and Servamine KAC ^TM(Dodecyl trimethyl ammonium chloride, ex Condea).Many not too significant biocidal properties that have are arranged in these materials.

WO 00/34423 (Unilever, 2000 open) discloses incorporating into of cationic material and how to have brought a difficult problem owing to form mixture between anionic detergent and cationic material.Recommended cationic material comprises didecyl methyl-benzyl ammonium chloride in WO 00/34423, Timbercote 2000, other this compounds of didecyl methyl-propyl ammonium chloride and " many ".WO 00/34423 points out that this thing cationic compound of killing livestock can use separately or combination with one another is used.

The present invention relates in the laundry detergent product, incorporate biocidal cationic material into and do not lose overall washing (-)off properties.

Summary of the invention

The inventor has determined, when with aniorfic surfactant/when the nonionic surface active agent system is used the specific mixture of the cationic surfactant with different structure, can obtain effective biocidal activity, keep acceptable washing (-)off properties simultaneously at the microorganism relevant with producing stench.

Therefore, the invention provides laundry cleaning compositions, it comprises:

A) at least a in washing assistant, enzyme, fluorescent agent, perfume compound, antiredeposition polymkeric substance, soil release polymer, source of alkalinity, the sequestrant that is not used in hardness ions, SYNTHETIC OPTICAL WHITNER or its precursor and,

B) surfactant system, it comprises:

I) based on one or more aniorfic surfactant of total surfactant at least 1 weight %,

Ii) optional based on total surfactant at least 1 weight % one or more nonionic surface active agent and,

Iii) based on the blended cationic surfactant system of total surfactant 0.5-30 weight %, it is by with 9: 1-1: second cationic surfactant shown in first cationic surfactant shown in one or more general types (I) that 9 weight ratio exists and one or more general types (II) is formed, wherein:

The cationic surfactant of type i is the quaternary ammonium compound shown in the following general formula:

R ⁵Be R ²Or H,

Condition is that then the cationic surfactant of the type II should only be considered to the cationic surfactant of type i if the structure of the cationic surfactant of Type II makes it fall in the range of definition of cationic surfactant of type i.

Usually, think that the cationic surfactant of type i is than the more effective biocide of the cationic surfactant of Type II.Think that the cationic surfactant of Type II more tolerates the precipitation that is caused by aniorfic surfactant such as LAS than the cationic surfactant of type i.Notice that the tensio-active agent of Type II comprises alkoxyl group or hydroxyl-alkyl.These oxygenated species (species) are perhaps partly replaced or the prolongation low-grade alkyl substituent between the alkyl of quaternary nitrogen atom and relative long-chain.As mentioned above, the composition of the present invention cationic surfactant (it is believed to be helpful in clean) of the cationic surfactant of containing type I (it is considered to more effective biocidal) and Type II all the time.If there is the cationic surfactant of the interior Type II of the description scope of the cationic surfactant that also falls into type i, must there be the cationic surfactant of other Type II so, makes to have some Type II all the time but not the cationic surfactant of type i.

Type i: the preferred weight ratio of Type II tensio-active agent is preferably 1: 1 to 5: 1, and more preferably 2: 1 to 4: 1, special preferred weight ratio was about 3: 1.Believe that most preferred combination shows that not only washing (-)off properties do not have obvious reduction, and be presented at the synergistic benefits of microorganism killing aspect.

Any suitable counter ion all can be used in the cationic surfactant.The preferred counter ion that are used for cationic surfactant comprise halogen ion (particularly chlorion), methyl-sulfuric acid root (methosulphate), etherosulfuric acid root (ethosulphate), tosylate, phosphate radical and nitrate radical.Chlorion preferably.Preferably except the described blended cationic surfactant of the highest 30% formation system, there is not other cationic surfactant.
