Abstract

An improvement is described in microemulsion compositions which are especially effective in disinfecting the surface being cleaned and in the removal of oily and greasy soil without leaving streaks which contains a mixture of a nonionic surfactant, a cationic surfactant and an amphoteric surfactant, a hydrocarbon ingredient, natural disinfectant ingredients, a water soluble solvent, and water.

Claims

1. A microemulsion composition consisting essentially of approximately by weight:

(a) 0.1% to 20% of at least one disinfecting agent which is selected from the group consisting of a C₈ -C₁₆ alkyl amine, a C₈ -C₁₆ dialkyl dimethyl ammonium chloride, C₈ -C₁₆ alkyl benzyl dimethyl ammonium chlorides, chlorohexidine and mixtures thereof;

(b) 0.1 wt. % to 20 wt. % of at least one surfactant selected from the group consisting of an ethoxylated nonionic surfactant and a compound which is a mixture of;

##STR7## wherein w equals one to four, B is selected from the group consisting of hydrogen and a group represented by;

##STR8## wherein R is selected from the group consisting of alkyl group having 6 to 22 carbon atoms, and alkenyl groups having 6 to 22 carbon atoms, wherein at least one of the B groups is represented by said ##STR9## R'"'"' is selected from the group consisting of hydrogen and methyl groups;

X, Y and Z have a value between 0 and 60, provided that (X+Y+Z) equals 2 to 100, wherein in formula (I) the ratio of monoester/diester/triester is 40 to 90/5 to 35/1 to 20, wherein the ratio of formula (I) to formula (II) is a value between 3 to 0.02;

(c) 0.1% to 20% of an amphoteric surfactant selected from the group consisting of having the general formula;

##STR10## wherein X³¹ is selected from the group consisting of CO₂ -- and SO₃ -- and R₁ is an alkyl group having 10 to about 20 carbon atoms, or an amido radical;

##STR11## wherein R is an alkyl group having about 9 to 19 carbon atoms and a is the integer 1 to 4;

R₂ and R₃ are each alkyl groups having 1 to 3 carbon atoms;

R₄ is an alkylene or hydroxyalkylene group having from 1 to 4 carbon atoms and, alkylamino carboxylates;

(d) 1% to 12% of a water souluble solvent which is selected from the group consisting of mono- and di- C₁ -C₆ alkyl ethers and esters of ethylene glycol and propylene gylcol;

(e) 0.4% to 10% of a water insoluble organic hydrocarbon, essential oil or a perfume; and

(f) the balance being water.

2. The composition according to claim 1, wherein said glycol ether is propylene glycol n-butyl ether.

3. The composition according to claim 1, further including a C₁ -C₃ alcohol.

4. the composition according to claim 1, further including an amine oxide characterized by the formula:
