Other anion component comprises carboxylate, and its non-limiting example comprises the lauroyl carboxylic acid sodium, cocoyl carboxylic acid sodium, and lauroyl carboxylic acid ammonium.Anionic fluorosurfactants also is suitable for.

Counter cation M is applicable in the anion surfactant.Preferred counter cation is selected from sodium, potassium, ammonium, monoethanolamine, diethanolamine and triethanolamine.More preferably counter cation is an ammonium.

When being used for the surfactant of antimicrobial cleansing compositions of the present invention, selection should consider 3 factors: the activity of (1) surfactant molecule in bacterial cell membrane; (2) dissolubility of Xuan Ding active component in surfactant; And the mildness of (3) surfactant, it can influence the mildness index (seeing below) of bactericidal composition.The mildness of biological activity/surfactant

In general, the biological activity of surfactant is high more, and the time-delay activity of compositions that contains this surfactant is big more.But in general, the biological activity of surfactant and its mildness are inversely proportional to; The biological activity of surfactant is high more, and its zest is high more, and the biological activity of surfactant is low more, and it is soft more.No matter be biologically active but the surfactant that stimulates, the still active but surfactant of gentleness of inanimate object all depends on certainly or influences other components selection.

Can directly measure the biological activity/mildness of the pure surfactant that characterizes by the microcytotoxicity index by microcytotoxicity reaction test (analytical method that sees below part).Wherein " pure surfactant " is meant the chemical composition that is made of a kind of surfactant entity substantially, and wherein this entity has only a chain length, end group and salify counter ion basically.For the viewpoint of high bioactivity, the microcytotoxicity index of Response that is preferred for the anion surfactant of antimicrobial cleansing compositions of the present invention is lower than 150, more preferably less than 100, most preferably is lower than 50.For the viewpoint of mildness, the microcytotoxicity index of Response of anion surfactant that is preferred for antimicrobial cleansing compositions of the present invention is greater than 25, more preferably greater than 50, most preferably greater than 100.The microcytotoxicity index of Response is that the surfactant of 25-150 generally has medium biological activity and medium mildness.

Surface activator composition generally is a surfactant mixture, rather than pure surfactant (comprises " technical grade " surfactant, wherein generally comprise the mixture of the entity of different chain length, wherein also may contain high-load impurity), be difficult for measuring biological activity or mildness by the microcytotoxicity index of Response of each surface active agent composition.When said composition is mixture, can measure the microcytotoxicity index of each independent component, if all components in the compositions all is known, then its weighted mean can be used as index.If each component is not known in the compositions, the then main chain end group of surfactant and the more suitable index of chain length as biological activity/mildness.

For the viewpoint of high bioactivity, the chain length of anion surfactant or surfactant mixture is 8-24 carbon atom substantially, is preferably 10-18 carbon atom, most preferably is 12-16 carbon atom.Here used term " substantially " refers to be at least 50%.For the viewpoint of mildness, preferably reduce to C ₁₂

For bioactive viewpoint, the end group of preferred anionic surfactant is lower than 15 dusts, preferably is lower than 10 dusts, more preferably less than 7 dusts." end group " is meant hydrophilic (nonhydrocarbon) part of anion surfactant, counts molecular chain-end from first polarity atom.The size of end group will be predicted according to the van der Waals radius of atom and the configuration of surfactant molecule.The end group that size is lower than 7 dusts comprises sulfate radical, sulfonate radical and phosphate radical.For the viewpoint of mildness, preferred end group is preferably greater than 10 dusts greater than 7 dusts.End group greater than 10 dusts comprises ethoxylation sulfate radical, glyceryl ether sulfonic acid root and isethionic acid root.Size that it is generally acknowledged end group is big more, prevents in the cell wall that the destructive stearic class blockage of surfactant is many more, and biological activity will reduce, and mildness increases.

The mildness of surfactant or surfactant mixture also can be measured through many conventional methods that become known for measuring the surfactant mildness.For example " Dermatology research impurity " (J.Invest.Dermatol., 1975,64,190-195 page or leaf) and the sealing coat failure test that proposes in US4673525 (people such as Small, 1987.6.16 authorizes), described content all is combined in herein as a reference.In general, surfactant is gentle more, and the destructiveness of skin sealing coat is low more in the sealing coat failure test.Enter in the detected solution of the diffuser casing that contains physiologic buffer through the respective amount of radiolabeled water by measuring, measure the destruction of skin sealing coat by epidermis.Skin sealing coat osmotic value has suitable mildness near the surfactant of 0-75 relatively.Relative skin sealing coat osmotic value has zest greater than 75 surfactant.The dissolubility slope of antimicrobial acivity composition in the anion surfactant

Being chosen in of preferred anionic surfactants surfactant also depended on the antimicrobial acivity composition to a certain extent from surfactant sedimentary ability on skin.Be applicable to that surfactant of the present invention should have enough dissolubilities to active component, but dissolubility again can not be too high, active component is retained in the solution and can not deposits on the skin in preventing to use.We find can measure optimum balance by antimicrobial acivity composition dissolubility with respect to the slope of curve of surfactant concentration in water.The mensuration of this slope (being called the dissolubility slope) K is seen the analytical method part.

The dissolubility slope K of preferred anionic surfactants surfactant of the present invention is lower than 0.60, preferably is lower than 0.40, more preferably less than 0.25, most preferably is lower than 0.10.

The preferably deposition 0.01 μ g/cm on skin of type antimicrobial cleansing compositions that floats of the present invention ²-100 μ g/cm ²Anti-microbial active, more preferably 0.1 μ g/cm ²-50 μ g/cm ², 1 μ g/cm most preferably ²-20 μ g/cm ²

For making this personal cleaning compositions effective, must take into account the dissolubility of used given activity composition in the biological activity of surfactant and the surfactant simultaneously.

For example, ammonium lauryl sulfate (ALS) has high biological activity (microcytotoxicity index=1.0), but dissolubility slope higher (K=0.3).Because the activity of ALS, though with the antibacterial activity composition of low content and shared to proton reagent, the compositions that contains ALS still has the antimicrobial acivity of extremely effectively delaying time.But for to make active component be deposited on (to satisfy above-mentioned requirement to effect) on the skin, the high-dissolvability slope will require high-load active matter.In addition, contain in the compositions of ALS and also need add cosurfactant or polymer (seeing non-essential component portion) to reach the most preferred mildness of the present invention.

Select for use lauryl ether-3 ammonium sulfate (microcytotoxicity index=120, and K=0.5) can make compositions as mild as a dove, but, need to adopt high-load proton reagent and the antimicrobial acivity composition given for reaching the present invention's effect of delaying time as surfactant.

The alkane sulfonate that has little end group, average chain length and be 15.5 (K=0.1) is active higher surface activity agent, and the deposition degree of active component is very high, and it is purchased grade product is the Hastapur SAS  by name that is produced by Hoechst Celanese.The active component and the sour compositions that contain low content can be shared with high-load alkane sulfonate, and wherein surfactant plays most of effect to the time-delay effect of compositions.Also can the alkane sulfonate and the high-load active component of low content is shared in the compositions, to obtain gentleness and effective composition.Can the active component and the alkane sulfonate of moderate content is shared, because its dissolubility index shows that the deposition degree of active component in the said composition is very high.

The non-limiting example that is applicable to preferred anionic surfactants surfactant of the present invention comprises that chain length is mainly the alkylsurfuric acid ammonium and the alkyl sodium sulfate of 12-14 carbon atom, and alkyl ether ammonium sulfate and sodium alkylether sulphate, chain length is mainly the olefin sulphates of 14-16 carbon atom, and chain length is the alkane sulfonate of 13-17 carbon atom and their mixture.What especially preferably be applicable to this is ammonium lauryl sulfate and sodium lauryl sulfate; Myristyl ammonium sulfate and Semen Myristicae sodium sulfate; The ammonium sulfate and the sodium salt of lauryl ether-1, lauryl ether-2, lauryl ether-3 and lauryl ether-4; C _14-16Alkene sulfonic acid ammonium and sodium salt, C _13-17Alkane sulfonate and their mixture.

Have found that, with high-load non-anion surfactant and the shared effect that in fact can reduce delay feature of high-load anion surfactant that constitutes by non-ionic surface active agent, cationic surfactant, amphoteric surfactant and their mixture.This is the most obvious for cationic surfactant and amphoteric surfactant, it is generally acknowledged that these surfactants can hinder the destruction of lipid in (interaction between electric charge) anion surfactant cell membrane.The amount ratio of these other surfactants and anion surfactant should be lower than 1: 1, preferably is lower than 1: 2, more preferably less than 1: 4.
