5. Quaternary ammonium compound

The present invention also can randomly comprise cats product, particularly quaternary ammonium surfactant.The tensio-active agent of these types typically is used for bathroom detergent because they are considered to " wide spectrum " antimicrobial compounds usually, its not only to Gram-positive (for example, Staphylococcus ( Staphylococcus sp.)) and to Gram-negative (for example, bacillus coli ( Escherischia coli)) microorganism is all powerful.Therefore, for antibacterial/disinfectant purpose is mixed quaternary ammonium surfactant or compound, and these compounds should be effectively to measure this purpose and to exist.

Quaternary ammonium compound is selected from the tetraalkyl ammonium compound of single long-chain, three short chains, the tetraalkyl ammonium compound of two long-chains, two short chains, trialkyl, monobenzyl ammonium compound and their mixture." long-chain " refers to about C _6-30Alkyl." short chain " refers to C _1-5Alkyl, be preferably C _1-3° preferred material comprises Stepan series, as BTC 2125 series; Barquat and Bardac series are as the BardacMB2050 of Lonza chemical company.The preferably about 0-5% of the typical content of quaternary ammonium compound, more preferably about 0.001-2%.

6. Water

Water is main component, and its content should be at least about 70%, more preferably at least about 80% with most preferably at least about 90%.Deionized water is most preferred.Water forms the external phase that accounts for leading role, and other component is dispersed in wherein.

7. Other additive

For the aesthetic property that improves product of the present invention can add amounts of additives.Aesthstic additive comprises essence, as available from Givaudan-Rohre, international fragrance essence (International Flavors and Fragrances), Firmenich, Norda, Bush Broke and Allen, those of Quest and other company also have solubilized or are suspended in dyes and dyestuffs in the preparation.Because microemulsion is transparent colourless liquid, can adds various dyestuffs or tinting material and give a kind of aesthetic or commercial satisfactory appearance.The amount of these aesthetic property additives should be 0-2%, more preferably 0-1%.It is favourable adding other antiseptic-germicide in prescription of the present invention.Thereby the phenols of replacement those as finding in the U.S. Pat 4985945 of Moseman are hereby incorporated by, or para-chlorometaxylenol.Here sequestrant also can be useful, as most preferably, is aminopolyphosphonic acid salt.Sequestrant is selected from a large number to the effective known agent of chelating heavy metal ion.Sequestrant should be able to be resisted the quick oxidation of hydrolysis and oxidized dose.Preferably, it should have the about 1-9 of acid dissociation constant (pKa), shows that it dissociates when hanging down pH, with the binding ability of raising with metallic cation.Most preferred sequestrant is the aminopolyphosphonic acid salt available from Monsanto company commodity Dequest by name.Their example is Dequest2000,2041 and 2060.(also go to the 13rd hurdle the 22nd, be hereby incorporated by) referring to U.S. Pat 4473507, the 12 hurdles the 63rd row of Bossu.Polyphosphonic acid salt such as Dequest2010 also are fit to use.Other sequestrant such as ethylenediamine tetraacetic acid (EDTA) (EDTA) and nitrilotriacetic acid (NTA) also can be suitable for.Also having other preferred sequestrant is new trimethylenedinitrilo-tertraacetic acid salt, as Hampshirel available from W.R.Grace, and 3 PDTA and available from the Chel DTPA100#F of Ciba-Geigy A.G..The mixture of aforementioned substances also can be suitable for.Being used for solid dispersed among the present invention also is useful to the hydrotropic agent (hydrotropes) of liquid phase.These hydrotropic agents are different from tensio-active agent, because they do not form micelle-forming concentration (CMC) in aqueous liquid dispersion.Some suitable hydrotropic agents comprise short-chain alkylarenesulfonate, more particularly C _1-4Alkylaryl sulphonate, as, be not confined to benzene, naphthalene, dimethylbenzene, isopropyl benzene and tosylate.In addition, because tensio-active agent is subjected to the attack of microorganism sometimes in liquid system, it is favourable adding mould inhibitor and fungistat.The example of mould inhibitor (comprising non-isothiazolone compounds) comprises Kathon GC, a kind of 5-chloro-2-methyl-4-isothiazoline-3-ketone, Kathon ICP, a kind of 2-methyl-4-isothiazoline-3-ketone, with its mixture, with Kathon 886, a kind of 5-chloro-2-methyl-4-isothiazoline-3-ketone, all these are all available from Rohm and Haas company; Available from the Bronopol of Boots company limited, a kind of 2-bromo-2-nitropropane 1,3-glycol; Available from the ProxelCRL of ICI PLC, a kind of right-nipasol; Available from the Nipasol M of Nipa Laboratories Ltd., the Na of a kind of neighbour-phenyl-phenol ⁺Salt; Available from the Dowicide A of Dow chemical company, a kind of 1, the 2-benzisothiazole-3-ketone; With Irgasan DP 200 available from Ciba-Geigy A.G., a kind of 2,4,4 '-three chloro-2-dihydroxy diphenyl ethers.Also, be hereby incorporated by referring to people's such as Lewis U.S. Pat 4252694 and US4105431.Preferably avoid those additives that can cause particle suspension in the microemulsion, for example, salt (as NaCl, Na ₂SO ₄), washing assistant, ionogen, enzyme, pigment etc.Use dyestuff in the present invention, tinting material and pigment are in order that give a kind of aesthetic satisfactory color of preparation or tone, and said preparation is preferably transparent.The supplier of such dyes and dyestuffs comprises the Aldrich chemical company.

9. The interpolation order

Be surprisingly found out that also the interpolation of component of the present invention is very crucial in proper order.As if under the guidance of EP150894, in proper order the interpolation of component is left to last interpolation as prerequisite with the less component of solvability.Be surprisingly found out that, in the present invention, must be mixed together together with water and add polymer viscosifier so that the thickening material hydrolysis.Preferably, add alkali or other ealkaline buffer of appropriate amount, help lend some impetus to or quicken hydrolysis.Preferably add oxidation inhibitor/rheology stablizer so that help to disperse oxidation inhibitor with pine tar.Thereby interpolation is generally in proper order: water, thickening material; Ealkaline buffer (optional), pine tar, oxidation inhibitor (preferably adding) with pine tar, tensio-active agent, quaternary ammonium compound (if any) is aesthstic additive such as dyestuff and/or essence then.This process should be carried out under constant temperature (about more than 0 ℃ to 50 ℃, more preferably about 22 ℃) and constant speed stir.

Adopt of the present invention this to add in proper order and can cause best rheology stability.

Experimental section has below proved that detergent formulations of the present invention has wonderful stability.
