Liquid concentrated surfactant compositions
Liquid concentrated surfactant compositions including an anionic surfactant, a non-ionic surfactant, and a cationic surfactant are disclosed. The liquid concentrated surfactant compositions are substantially free of any water or solvent and consist substantially of the surfactants. The liquid concentrated surfactant compositions are effective as cleaning compositions.
1. A liquid composition comprising:
one or more anionic sulfonated surfactants comprising a salt of a linear or branched alkyl benzene sulfonic acid formed with a neutralizing agent comprising monoisopropanolamine;
one or more non-ionic surfactants; and
about one or more hydrophilic cationic surfactants comprising a quaternary ammonium formed from a polyethylene glycol derivative of cocamine; and
wherein about 90%, by weight, or more of the composition comprises the one or more anionic sulfonated surfactants, the one or more non-ionic surfactants, and the one or more hydrophilic cationic surfactants.
2. The liquid composition of claim 1 , comprises about 0.5% to about 5%, by weight, of the one or more hydrophilic cationic surfactants.
3. The liquid composition of claim 1 , wherein the one or more non-ionic surfactants comprise a C 8 -C 16 linear alkyl alcohol ethoxylate, the C 8 -C 16 linear alkyl alcohol ethoxylate having an average of about 3 mol to about 10 mols of ethylene.
4. The liquid composition of claim 1 , comprises:
linear alkyl benzene sulfonate;
cocoalkylmethyl PEG-15 ammonium chloride; and
a C 8 -C 16 linear alkyl alcohol ethoxylate.
5. The liquid composition of claim 1 , comprises:
about 30% to about 45%, by weight, of the one or more anionic sulfonated surfactants;
about 1% to about 5%, by weight, of the one or more hydrophilic cationic surfactants; and
about 35% to about 50%, by weight, of the one or more non-ionic surfactants.
6. The liquid composition of claim 1 , comprises
about 35% to about 45%, by weight, of linear alkyl benzene sulfonate;
about 1% to about 3%, by weight, of propoxylated quaternary ammonium or propoxylated quaternary amine; and
about 40% to about 50%, by weight, of a C 8 -C 16 linear alkyl alcohol ethoxylate.
7. The liquid composition of claim 1 further comprising one or more additives; and
wherein the one or more additives comprising one or more of propylene glycol and an amphoteric surfactant, the amphoteric surfactant comprising sodium lauriminodipropionate.
8. The liquid composition of claim 7 comprising about 3% to about 5%, by weight, of the amphoteric surfactant; and
about 5% to about 35%, by weight, of the propylene glycol.
9. The liquid composition of claim 1 has a dynamic viscosity of about 100 cP to about 2,000 cP.
10. The liquid composition of claim 1 has a pH of about 7 to about 8 when dispersed in deionized water at a concentration of 10%, by weight, of the liquid composition.
11. The liquid composition of claim 1 consists essentially of surfactants.
12. A liquid composition consisting essentially of:

optionally one or more of propylene glycol and an amphoteric surfactant; and
wherein about 90% or more, by weight, of the liquid composition comprises surfactants.
13. A method of forming a liquid composition comprising:
mixing together until substantially clear and homogenous:
one or more anionic sulfonated surfactants, formed by reacting an anionic sulfonic acid with a neutralizing agent comprising monoisopropanolamine;
one or more non-ionic surfactants; and
one or more hydrophilic cationic surfactants comprising a quaternary ammonium formed from a polyethylene glycol derivative of cocamine; and
