Definitions

  • This invention relates to liquid detergents, and more particularly to a liquid light duty detergent composition complete with all the ingredients, including the minor components, having a high concentration of active materials, in the form of a viscous liquid, quickly dilutable in water, adapted for preparing liquid detergents ready to be used.
  • Detergents and more particularly liquid detergents, are substantially formed by surfactants, either of anionic, non-ionic or amphoteric type, defined as active agents, and by various materials added to obtain particular effects, such as for example bleaching agents or builders in case of laundering products, or abrasive powders in case of bathroom or kitchen-cleaning products, and/or minor agents such as electrolytes, perfumes, anti-fermentation agents, dyes, and the like.
  • surfactants either of anionic, non-ionic or amphoteric type, defined as active agents, and by various materials added to obtain particular effects, such as for example bleaching agents or builders in case of laundering products, or abrasive powders in case of bathroom or kitchen-cleaning products, and/or minor agents such as electrolytes, perfumes, anti-fermentation agents, dyes, and the like.
  • anionic surfactants the most widely used in the straight chain alkylaryl sulfonate, in the form of its sodium, potassium, ammonium and alkanol ammonium salts (LAS Na, LAS K, LAS Tea), or combination of the above.
  • alkylaryl sulfonates also sodium alkane-sulfonates (SAS Na), sulfonated -olefines, and sodium alkylethoxy sulfates (AES Na) of low ethoxylation type are frequently used.
  • SAS Na sodium alkane-sulfonates
  • AES Na sodium alkylethoxy sulfates
  • non-ionic surfactants the most widely used are the ethylene oxide condensates of alkanolamides of fatty acids, fatty alcohols, or alkylphenols.
  • amphoteric surfactants the betaine derivatives, imidazole derivatives, and amine oxides are widely used.
  • Concentrated detergent compositions comprising a mixture of anionic, non-ionic and amphoteric surfactants, are known.
  • composition of the above mentioned prior art patent so as to obtain: a) a concentrate containing about the 70% of active matter; b) by reducing the non-ionic surfactants content in the composition and c) by eliminating the free alkali in the composition so as to obtain a neutral pH value, as highly desirable especially for a light duty and dishwashing detergent, a dissolving time of more than 60 minutes was obtained.
  • the main obstacle in the formulation of such a product is the low water solubilization speed of almost all the most-commonly used surfactants when they are in a highly concentrated form, which is, obviously, the only possible form for the product according to this invention.
  • the desired result is obtained of a quick and easy solubilization in water, lower than 3 minutes in many cases, by simple dilution with minimum stirring.
  • the object of this invention is to provide a complete detergent, represented by the composition of claim 1, characterized at the same time by the following features:
  • anionic surfactants have proved to be suitable, namely the straight-chain alkylarylsulfonates, particularly the salts of potassium and triethanolamine, the sodium alkansulfonates and the sodium alkylethoxy sulfates containing 2 to 3 moles of ethylene oxide.
  • alkane-sulfonates having an alkylic chain length in the range C 10 - 20 are used.
  • the said alkane-sulfonates may be used alone or in mixtures with alkylethoxy sulfates in a ratio 100:0 to 40:60.
  • the alkylethoxy sulfates comprise sodium salts of alkylsulfates with a chain length in the range Cg- 18 , particularly C 9 - 15 or C 12 - 18 , condensed with 3 moles of ethylene oxide.
  • solvents light alcohols with 1 to 3 carbon atoms, low molecular weight ketones such as acetone and methylethylketone, and some glycol ethers such as the monomethyl- and monoethyl-ether of ethylene glycol may be used.
  • the total active agents are formed, in addition to the anionic surfactant main constituents, also by non-ionic surfactants in smaller percentages, mainly as foam stabilizers and, due to their dispersing and fluidizing characteristics, in order to permit the admixture of minor additives, such as perfumes, into the composition without impairing the peculiar characteristics, particularly the high solubilization property of the composition.
  • the invention advantageously uses alkylphenols condensed with 4 to 9 moles of ethylene oxide, C 9 -C 15 straight chain alcohols condensed with 7 to 15 moles of ethylene oxide, and alkanolamides of fatty acids, e.g. of the coconut type, condensed with 1 to 5 moles of ethylene oxide.
  • the concentrated composition may incorporate therein water-soluble polymeric materials of the oxyethylene homopolymer type, e.g. those having a molecular weight in the range 400,000 to 5,000,000 and marketed under the Trademark "Polyox" registered by Union Carbide, preferably in concentrations of 0.005 to 3% more preferably of 0.05 to 2%.
  • the same objective of obtaining a diluted detergent composition with increased viscosity can be achieved by adding, separately, to the said concentrated composition during the dilution step, one or more viscosity-enhancing materials selected from the following groups:
  • acids are neutralized, in the mixing and diluting step, by basic materials, such as alkaline hydrates, ammonium hydroxide, alkanolamines, admixtured into the concentrated composition for this purpose;
  • basic materials such as alkaline hydrates, ammonium hydroxide, alkanolamines, admixtured into the concentrated composition for this purpose;
  • the main surfactants used in these examples are usually marketed and available materials, indicated by the symbols generally used to designate them in the technical literature (for example, LAS, SAS, AES), followed by the respective concentration of active agent.
  • Each formulation comprises the indication of the percentage composition, the contents of total active agent (anionic+non-ionic surfactants) and the solution time required to achieve the solubilization in water, at the ambient temperature, by simple manual shaking, to obtain diluted final solutions with 12% concentration of total active agent.
  • a combination is reported here of a concentrated composition into which, in the dilution step, viscosity-enhancing materials are added.
  • composition A a viscosity-enhancing material in the form of a polyacrylic acid in water emulsion and sodium chloride in the following ratios will be added to the composition A:
