Definitions

  • ABSTRACT A liquid detergent composition containing more than 25% (by weight; the same shall apply hereinafter) of a surfactant and a nitrilotriacetic acid salt.
  • the surfactant comprises a mixture of 30 to 55% of a straight chain alkylbenzene sulfonate, 30 to 60% of an a-olefin sulfonate and 5 to 20% of polyoxyethylene alkylor alkylphenyl ether.
  • the weight ratio of the nitril0triacetic acid salt to the surfactant is in the range of from about 0.1 to 3:1v
  • This invention relates to a liquid detergent composition. More particularly, this invention relates to a concentrated liquid detergent composition having excel lent solution stability and containing a special proportion of a surfactant mixture and a water-soluble salt of nitrilotriacetic acid.
  • This invention provides a liquid detergent composition containing more than 25 (all percentages herein are by weight, unless otherwise noted) of a mixture of (A) surfactant and (B) water-soluble salt of nitrilotriacetic acid.
  • the surfactant (A) comprises a mixture of 30 55% of straight chain alkylbenzene sulfonate, 30 60% of oz-olefin sulfonate and 20% of polyoxyethylene alkylor alkylphenyl ether.
  • the surfactant (A) contained in the liquid detergent composition of the present invention is a mixture of anionic surfactant and nonionic surfactant.
  • the anionic surfactant is a mixture of (1) straight chain alkylbenzene sulfonate in which the alkyl has an average number of carbon atoms in the range of to l4 and (2) a-olefin sulfonate having an average number of carbon atoms in the range of 14 to IS.
  • the anionic surfactant is an alkali metal salt such as sodium or potassium, ammonium salt or an alkanolamine salt such as mono-, dior triethanolamine.
  • the nonionic surfactant is a poly oxyethylene alkyl ether containing an alkyl group hav ing from 8 to l8 carbon atoms and 4 to 14 oxyethylene units, or a polyoxyethylene alkylphenyl ether containing an alkyl group having from 8 to 12 carbon atoms and 6 to 12 oxyethylene units.
  • the liquid detergent composition consists essentially of an aqueous solution of a mixture of A. one part by weight off surfactant consisting essentially of 30 55% of straight chain alkylbenzene sulfonate, 30 of a-olefin sulfonate and 5 20% of polyoxyethylene alkyl-or alkylphenyl ether and B. about 0.1 3 parts by weight, preferably 0.2 1 part by weight, per one part of (A), of a salt of nitrilotriacetic acid, such as an alkali metal salt such as sodium or potassium, ammonium salt or an alkanol amine salt such as mono-, dior triethanolamine, salt of nitrilotriacetic acid.
  • A one part by weight off surfactant consisting essentially of 30 55% of straight chain alkylbenzene sulfonate, 30 of a-olefin sulfonate and 5 20% of polyoxyethylene alkyl-or alkylphenyl ether and
  • the liquid detergent composition contains at least 25% of the sum of components (A) plus (B), mixed in the weight ratio specified above.
  • the upper limit of the amount of components (A) plus (B) in the liquid detergent composition is the amount at which all ingredients remain dissolved in the aqueous solution. This will vary depending on the particular components used but, in general, the maximum amount of components (A) plus (B) is from 40 to 50 percent.
  • the liquid detergent composition has an excellent solution stability at a high concentration above 25% at both low and high temperatures (i.e., it is transparent at -5C) and it demonstrates a great detergency performance.
  • the liquid detergent composition may be either a light duty detergent or a heavy duty detergent.
  • the latter may contain one or more inorganic builders such as sodium orthophosphate, sodium pyrophosphate, so dium silicate, sodium carbonate, sodium metaborate or borax in an amount which does not damage the solution stability of the composition.
  • the amount of inorganic builder in the heavy duty liquid detergent composition can be from 2 to 25%.
  • ingredients in both light duty and heavy duty detergents there can be used small amounts of an alkali metal, ammonium or amine salt of citric acid, gluconic acid, tartaric acid or malic acid and potassium pyrophosphate.
  • a solubilizer or a solvent such as an alkali metal salt, ammonium salt or an amine salt of ptoluene sulfonic acid, xylene sulfonic acid, ethylbenzene sulfonic acid or cumene sulfonic acid; or methanol, ethanol, propyl alcohol, propylene glycol, glycerol, methylcellosolve, ethylcellosolve, butyl-cellosolve, phenylcellosolve or ethylcarbitol.
  • a solubilizer or a solvent such as an alkali metal salt, ammonium salt or an amine salt of ptoluene sulfonic acid, xylene sulfonic acid, ethylbenzene sulfonic acid or cumene sulfonic acid
  • anticorrosive agent dye, perfume, fluorescent dye, enzyme, defoaming agent, foam inhibitor and germicide can optionally be incorporated in the composition.
  • EXAMPLE I The solubilities of sodium straight chain alkylbenzene sulfonate (an average of 12 carbon atoms in the alkyl group; hereinafter referred to as LAS), sodium a-olefin sulfonate (having an average of l6 carbon atoms; hereinafter referred to as A08) and polyoxyethylene(8)lauryl ether (hereinafter referred to an EMG) in water and also the solubility of sodium nitrilo- 3 tri-acetate (hereinatter rcterred to as NTA) in these aqueous solutions were examined.
  • LAS sodium straight chain alkylbenzene sulfonate
  • A08 sodium a-olefin sulfonate
  • NTA polyoxyethylene(8)lauryl ether
  • Cloths were washed in a Tcrg-O-Tomcter and the reflectivilics were measured. from which the dctcrgcncies were calculated.
  • Liquid detergent compositions I through IV of the present invention demonstrated detergent performances superior to those of known liquid detergent compositions (A) and (B) in both light and heavy duty detergents.
  • a transparent, stable, liquid detergent composition comprising an aqueous solution of A. as essentially the only organic surfactant components in the detergent composition, a three component surfactant consisting essentially of 1. from about 30 to about 55 percent by weight of straight chain alkylbenzene sulfonate 2. from about 30 to about percent by weight of a-olefin sulfonate, and
  • composition containing at least 25 percent by weight of the sum of constituents A and B.
  • a liquid detergent composition according to claim 1, in which the weight ratio of nitrilotriacetic acid salt (B) to constituent (A) is in the range of B/A (0.2- l.())/ l.
