  • compositions of the invention are single phase isotropic liquids which exhibit improved stability in that they return, or substantially return, to a single isotropic phase after freezing and thawing.
  • compositions of the invention also avoid yellowing of fabrics which are regularly softened with conventional cationic fabric softeners.
  • liquid detergent compositions herein comprise five essential ingredients:
  • compositions containing more than 40% by weight of such components tend to separate into a surfactant-rich soap phase and a salt-rich lye phase after freezing and thawing.
  • Preferred compositions herein contain less than 34%, and most preferably less than 28%, by weight of such components, and exhibit even greater stability in that they return to single phase isotropic liquids after being slowly frozen (e.g., over a period of days) and thawed.
  • the compositions, particularly those with higher surfactant and builder levels within the above limits also preferably contain the optional hydrotropes herein which help to solubilize the surfactants and salts in the water phase under a wide variety of conditions.

Whether the alcohol is derived from natural fats or produced by one of several petrochemical processes, a mixture of a carbon chain lengths is typical. The stated degree of ethoxylation is an average, the distribution being dependent on process conditions.
  • Ethoxylated alcohols are preferred because of their superior biodegradability relative to ethoxylated alkyl phenols. Particularly preferred are ethoxylated alcohols having an average of from 10 to 15 carbon atoms in the alcohol and an average degree of ethoxylation of from 3 to 8 moles of ethylene oxide per mole of alcohol.
  • the cloud point of a 1% aqueous solution of the ethoxylated nonionic surfactant is preferably below 75°C. and most preferably below 55°C.

  • the HLB value of surfactants and emulsifiers can be determined experimentally in a well-known fashion.
  • the HLB value of compounds or mixtures of compounds in which the hydrophilic portion of the molecule is principally ethylene oxide can be estimated by the weight ratio of ethylene oxide portion to the lipophilic portion (e.g., the hydrocarbyl radical).

  • the alcohol polyethoxylate sulfate surfactant is essential to the overall performance and stability of the present compositions. It has been found that if only the nonionic and amine oxide surfactants are present, fabrics which are regularly softened with conventional cationic fabric softening ingredients such as di-tallowdimethylammonium chloride will gradually become objectionably yellow. The reason for this effect is unclear, but in any event it can be controlled by the addition of an anionic surfactant to the compositions. Surprisingly, of the anionic surfactants tested, only the alcohol polyethoxylate sulfates can be added to the compositions in sufficient quantity to provide the desired effect without forming a separating phase or requiring the use of uneconomical amounts of compatibilizing materials.

  • Coconut and unsaturated C, 6 - 18 soaps such as oleyl are preferred for solubility reasons.
  • compositions herein also contain from 5% to 25%, preferably from 10% to 20%, by weight of a water-soluble nitrilotriacetate or citrate detergency builder capable of sequestering calcium or magnesium ions in water solution.
  • the essential detergency builders of the present invention have the ability to sequester calcium or magnesium ions in water solution, and also maintain or assist in maintaining an alkaline pH in a washing solution.

  • the cations are the same as or compatible with the anionic surfactants.
  • Phosphate esters particularly those with a predominance of single alkyl groups and designated primary esters, can have the hydropholic characteristics necessary to assist in the formation of an isotropic liquid detergent composition.
  • Emphos@ PS-413 and PS-236 (Witco Chemical Company) and Gafac@ PE-510 (GAF Corporation) are commercially available phosphate materials suitable as the hydrotrope in the practice of the invention.

  • Ethoxylated nonionic surfactants with a relatively high degree of ethoxylation and a corresponding high HLB value can find use in the compositions of the present invention.
  • hydrotropes especially mixtures of lower alkylbenzene sulfonates, such as toluene sulfonate, and phosphate esters, can be used, but preferably no phosphorus is present.
