Abstract

A homogeneous laundry detergent composition comprising an organic detergent, a fabric softener and a fabric conditioning agent selected from at least one of an organic silicone or an organic siloxane.

Description

  • The present invention relates to a laundry detergent composition and, particularly but not exclusively, to a laundry detergent composition having detergency properties in combination with fabric-core benefits.
  • In recent years modern washing machines have been manufactured to work on an automatic basis whereby an operator inserts a load of laundry to be washed in the machine and then adds the detergent followed by the selection of a preprogrammed automated wash cycle, said wash cycle selection depending on the material as well as the colour of the laundry. Typically, such washing machines are provided with a main compartment in the form of a drum which holds the laundry together with a separate detergent compartment. Once the operator initiates the automated wash cycle the washing machine pumps water into the detergent compartment which causes the detergent and water to mix and flow into the drum which will eventually rotate under the power of an electric motor in accordance with the particular automated wash cycle selected, thus, forcing the water through the laundry. Thereafter the drum will automatically drain of liquid in a spin cycle. The drum is then filled with clean water and a rinse cycle begins in order to remove any remaining detergent from the laundry, again followed by a spin cycle. Once all of the water has been removed and the laundry has been spun, the laundry may be removed from the drum of the washing machine.
  • Commonly, however, it is desirable to use a fabric softener in combination with a detergent. The fabric softener is typically based on a cationic surfactant, such as an amino compound (i.e. a quaternary ammonium salt), and is applied to the laundry by adding said fabric softener to a separate sub-compartment within the detergent compartment. After the first spin cycle, as mentioned above, water is pumped into the sub-compartment causing the fabric softener and water mixture to flow into the drum for the rinse cycle.
  • As a consequence of certain consumer driven initiatives, particularly the desire of the consumer for a reduction in cost of laundry detergents as well as an increase in convenience, the two-in-one laundry detergent comprising a detergent and fabric softener was created.
  • The two-in-one laundry detergent requires careful blending of the various components thereof, particularly when a liquid detergent is to be produced, in order to preserve the homogeneity of the detergent and, thus, ensuring that each quantity of detergent provides a uniform dosage of detergent and fabric softener.
  • The two-in-one laundry detergent suffers from several drawbacks, however, one being that fabric softeners used in such detergents do not always provide satisfactory fabric softening properties. Secondly, the two-in-one laundry detergent is susceptible to long term stability problems due to the low miscibility of a detergent and fabric softener.
  • The present invention has been made from a consideration of the above-mentioned problems.
  • According to a first aspect of the present invention therefore there is provided a homogeneous laundry detergent composition comprising an organic detergent, a fabric softener and a fabric conditioning agent selected from at least one of an organic silicone or an organic siloxane.
  • This composition is advantageous as said composition provides a three-in-one laundry detergent which has a satisfactory cleaning performance, exhibits excellent through-the-wash softening properties whilst additionally providing fabric conditioning benefits to the fabric being washed, such benefits including ease-of-ironing properties.
  • Furthermore, although the components of the laundry detergent composition are known individually it is surprising that they are capable of being combined such that they can work synergistically as a three-in-one laundry detergent composition along side each other.
  • In a preferred embodiment of the invention the fabric conditioning agent selected from an organic silicone or organic siloxane comprises at least one copolymer of polyalkyl siloxane and an organic quaternary ammonium salt or at least one copolymer or polyalkyl silicone and an organic quaternary ammonium salt. Preferred fabric conditioning agents include a dimethicone copolyol and/or a copolymer of polyalkyl siloxanes and organic quaternary groups, such as silicone Quaternium 8. Ideally, the fabric conditioning agent comprises dimethicone copolyol amido di-linoleyl ammonium chloride or a derivative thereof.
  • The detergent component of the present invention may be selected from any suitable anionic, amphoteric, non-ionic, zwitterionic surfactant or mixtures thereof. Preferred anionic surfactants include alcohol ether sulphates and/or sodium lauryl ethoxy (3EO) sulphate, e.g. Empimim KSN 27 (trade mark of Albright & Wilson). Preferred nonionic surfactants include alcohol ethoxylates, C13-C15 alcohol + 3 moles ethylene oxide, e.g. Synperonic A3 (trade name of I.C.I.), C13-C15 alcohol + 7 moles ethylene oxide, e.g. Synperonic A7 (trade name of I.C.I.). Preferred amphoteric surfactants include coco amido propyl dimethyl betaine (CAB), e.g. Genagen 818X (trade name of Hoechst), oleoamphocarboxyglycinates , e.g. Ampholak X07 (trade name of Akzo Nobel).
  • The fabric softener component of the present invention may be selected from any suitable cationic surfactant(s). Preferably the cationic surfactant comprises either alone or in combination surfactants selected from any suitable quaternary ammonium compound; quaternary pyridine based compound; quaternary dialkylester (such as Rewoquat WE 18); organic compounds having a C12 to C18 hydrocarbon chain of an amine, an ester, an acid or an amine oxide; or a derivative thereof.
  • The laundry detergent composition of the present invention may be provided in a solid particulate form or as a liquid dispersion. The detergent composition is preferably provided in the form of a liquid dispersion.
  • Where the detergent composition of the present invention is provided as a liquid dispersion a carrier fluid is provided which may be a polar solvent, preferably water.
  • Further components which may be utilised in the present invention include detergent builders, sequestrants, chelants, optical brighteners, opacifiers, pH modifiers, enzymes, enzyme stabilisers, antifoams, antiredeposition agents, bleaches, bleach activators, soil release polymers, perfumes, dye transfer protection means, antioxidants, colourants and zeolite dispersants.
  • Preferred sequestrants are phosphonates and/or amino-tri)methylene phosphonic acid), e.g. Dequest 2000 (trade mark of Solutia), preferred optical brighteners include stilbene derivatives, e.g. Leucophor MTD (Clariant Ltd). Preferred opacifiers include aqueous styrene/acrylic polymer dispersions e.g. Opacifiers 621 (trade name of Morton International Ltd).

  • The detergent composition is made, in a first instance, as two separate formulations. Each component of the two formulations is added in sequential number order.
    • First Formulation
  • Component Mass Kg %wt. of Final Composition
    1. Water 1192.0 39.733
    2. DEQUEST 2000 100.0 3.333
    3. Sodium hydroxide (32% Sol.) 100.0 3.333
    4. Sodium tripolyphosphate 100.0 3.333
    5. Empimin KSN 27 270.0 9.000
    6. CAB 40.0 1.333
    7. Perfume 6.0 0.200
    8. SYNPERONIC A7 45.0 1.500
    9. SYNPERONIC A3 15.0 0.500
    10. LEUCHOPOR MTD 6.0 0.200
    11. AMPHOLAC X07 120.0 4.000
    12. OPACIFIER 621 2.0 0.067
    13. Formalin 2.0 0.068
    14. 2.5% WILLIAMS BLUE 2.0 0.067
    Total 2000Kg 66,667%
    • Second Formulation
  • Component Mass Kg %wt. of Final Composition
    1. Water 962.07 32.069
    2. REWOQUAT WE 18 37.82 1.261
    3. SILICONE QUATERNIUM 8 0.11 0.003
    Total 1000.00Kg 33.333%
  • Once both the first formulation and the second formulation have been agitated sufficiently (i.e. - no agglomerates are present), the two formulations are combined under conditions of agitation. The resulting detergent composition is homogeneous, has long term stability properties and has a final weight of 3000Kg.
  • It is to be noted that the stability of the homogeneous detergent composition is directly related to the ratio in which the respective formulations are mixed. Increased levels of formulation 2 result in "splitting" of the final product. "Splitting" is where the two separate formulations are no longer miscible and separation thereof cannot be prevented.
  • It is to be understood that the above described embodiment is by way of example only and that many modifications and variations are possible.
