Definitions

  • the present invention relates to improved detergent compositions, suitable for use as cleaning compositions in laundry and in the washing of housewares such as including tableware, kitchenware, floors, and other hard surfaces, said detergent compositions demonstrating reduced aquatic toxicity characteristics.
  • the present invention further relates to a method of manufacturing said detergent compositions and the use thereof in cleaning operations.
  • Detergent compositions are ubiquitous and widely applied in domestic, institutional and industrial settings, especially with reference to their use as laundry detergent compositions, (manual) dishwashing detergent compositions, hard surface detergent compositions, and cleaning compositions in general for all sorts of applications wherein materials are contaminated with soils such as carbohydrate soils, protein soils, blood and water hardness soils in terms of high amounts of dissolved calcium and magnesium in water and soap scum, food oils soils, fat soils, and greasy soils thereby including sebum, cosmetics (e.g. lipstick), and dirty motor oil.
  • detergents are complex chemical compositions composed of surfactants and various additives, such as chelating agents, anti-redeposition agents, and fragrances.
  • Surfactants being large volume chemicals, constitute the predominant component in detergent or cleaning compositions, whether it be for household or professional use.
  • the incorporation of one or more surfactants in detergent compositions serves the purpose of reducing the interfacial tension between oil and water by adsorbing at the liquid-liquid and/or liquid-solid interface.
  • surfactants provide detergent compositions with the ability to remove soil from surfaces and further dispersion of said soil in the washing liquor.
  • each surfactant molecule is characterized by a hydrophilic head part, said hydrophilic head part being attracted to surrounding water molecules, and a hydrophobic tail part, said hydrophobic tail part repelling surrounding water molecules and simultaneously attaching itself to oil and grease in soil.
  • surfactants disperse soil that normally does not dissolve in water by itself. Therefore, surfactants constitute the key component in detergent or cleaning compositions by detaching stains and further keeping the soil in the surrounding aqueous environment thereby preventing re-deposition of the soil onto the surface from which it has been removed.
  • surfactants are generally of four types namely anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants.
  • Amphoteric surfactants have polar functional groups whose charge depends on the pH of the aqueous solution in which they are contained, and they exhibit cationic behavior at acidic pH, anionic behavior at alkaline pH, and are zwitterionic around their isoelectric point.
  • US 5,698,505 discloses liquid or gel dishwashing detergent compositions which exhibit good grease emulsification performance.
  • the described detergents compositions comprise anionic surfactants including C8-22 alkyl ether sulfates, nonionic surfactants including polyhydroxy fatty acid amides, and high amounts of C12 to C16 amine oxides for spontaneously emulsifying greasy/oily soils.
  • US 4,133,779 describes detergent compositions useful in the removal of greasy soils, said detergent compositions containing a water-soluble amine oxide as a semi-polar nonionic detergent as combined with an alkaline earth metal salt of an anionic detergent such as including linear alkyl benzene sulfonates, alkyl sulfates, alkyl ether sulfates, and alkyl glyceryl ether sulfonates.
  • GB 1458798 discloses liquid, concentrated, homogenous, aqueous detergent compositions, designed in particular for hand- washing tableware.
  • the liquid detergent compositions of GB 1458798 preferably contain: (A) a water soluble aliphatic sulphonate of formula (I); (B) a water soluble polyethylene glycol ether sulphate of formula (II); (C) a nonionic tertiary amine oxide of formula (III); (D) a water soluble aliphatic sulphate of formula (IV); and, optionally, (E) a reaction product of ethylene oxide and an organic hydrocarbon having a reactive hydrogen atom and from 8 to 20 carbon atoms, said liquid detergent compositions further being characterized by specific (A) / (B); and (C) / [(A) + (B)] weight ratios and a maximum amount of (D) + (E).
  • the disclosure of GB 1458783 relates to a liquid concentrated, homogeneous, aqueous detergent composition, designed in particular for hand-washing tableware.
  • a liquid concentrated, homogeneous, aqueous detergent composition designed in particular for hand-washing tableware.
  • balanced ratios of selected anionic and nonionic surface-active agents are described.
  • the liquid detergent compositions of GB 1458783 preferably contain: (A) a water soluble aliphatic sulphonate of formula (I); (B) a water soluble aliphatic sulphate of formula (II); (C) a water soluble polyethylene glycol ether sulphate of formula (III); (D) a tertiary amine oxide of formula (IV); and (E) a reaction product of ethylene oxide and an organic, hydrophobic compound having 8 to 20 carbon atoms and at least one reactive hydrogen atom, said liquid detergent compositions further being characterized by specific (A) / (B); (A) / (C); (D) / (A); and (B) / (E) weight ratios and a maximum amount of (B) + (E).
  • detergent compositions may pollute water and may, when present in sufficiently high concentrations, constitute toxicity problems to aquatic organisms, especially in untreated effluents for example when spilled into rivers or lakes without purification.
  • Numerous scientific studies reported that detergent compositions, thereby also including biodegradable detergent compositions, may have poisonous effects in one or more types of aquatic life if these compositions are present in sufficient quantities. Indeed, concern over the potential environmental impact of detergents and some of the components contained therein has led to extensive study of their environmental effects. For example, Warne, M. St. J. et al.
  • These treatment strategies may include physicochemical and biological methods of surfactant detoxification. Examples of these treatment strategies may further include effective remediation methods such as oxidation-based ozonation (O3), photocatalytic degradation via exposure to UV radiation, catalyst-coupled auto-oxidation, electrochemical degradation, and microbial biodegradation.
  • O3 oxidation-based ozonation
  • Another suitable strategy to reduce surfactant toxicity is to immediately act on the chemical and molecular architecture of the specific surfactant itself, i.e. prior to any usage and discharge thereof.
