Definitions

  • the present invention relates to a composition for cleaning comestibles, in particular, fruit and vegetables.
  • WO 2018/044840 discloses a method of reducing microbes on a food surface and a hard surface. It discloses antimicrobial composition comprising two cationic surfactant and one of the cationic surfactants is a quaternary ammonium cation. It further discloses that the composition may have a second cationic surfactant, an antibiotic and an amino poly-carboxylic acid.
  • composition comprising 0.1 to 2% wt. non-ionic surfactant, a vicinal diol and a quaternary ammonium salt, for cleaning comestibles wherein the diol has 7 to 14 carbon atoms.
  • compositions Often efficacy of such compositions depends on the amount of actives, i.e., surfactant, antimicrobial agents etc. present in the composition. Low amount of the actives may lead to insufficient cleaning. Whereas excess amount of the actives may leave residue of the actives on the comestibles, which is not preferred by the consumers. Therefore, it is also desired that the cleaning compositions provide enhanced antimicrobial efficacy, yet do not leave residue on the comestibles.
  • actives i.e., surfactant, antimicrobial agents etc.
  • compositions also comprising a diol and a quaternary ammonium salt.
  • the composition comprises 0.1 to 2% wt. non-ionic surfactant.
  • the surfactant is present at from 0.5 to 1.8% wt. , more preferably 0.5 to 1.5% wt. of the composition.
  • Non-ionic surfactants generate less foam than anionic surfactants.
  • Non-ionic surfactants are characterized by the presence of a hydrophobic group and an organic hydrophilic group and are typically produced by condensation of an organic aliphatic or alkyl aromatic hydrophobic compound with ethylene oxide.
  • the non-ionic surfactant comprises alkoxylated alkanols in which the alkanol is of 9 to 20 carbon atoms and wherein the number of molecules of alkylene oxide (of 2 or 3 carbon atoms) is from 5 to 20.

  • non-ionic surfactant is selected from an alkoxylated linear alcohol, more preferably an ethoxylated linear alcohol.
  • Exemplary of such compounds are those in which the alkanol is of 10 to 15 carbon atoms and which contain about 5 to 12 ethylene oxide groups per mole, e.g. NeodolTM family, Tergitol 15-S-7 etc. These are condensation products of a mixture of higher fatty alcohols averaging about 12 to 15 carbon atoms with about 9 moles of ethylene oxide.
  • the higher alcohols are primary alkanols.
  • alkoxylated surfactants which may be used contain a precise alkyl chain length rather than an alkyl chain distribution of the alkoxylated surfactants.
  • these are referred to as narrow range alkoxylates.
  • these include the NeodolTM-1 series of surfactants.
  • Non-ionic surfactants are represented by the commercially well-known class of nonionic surfactants sold under the trademark PlurafacTM from BASF.
  • the PlurafacTM are the reaction products of a higher linear alcohol and a mixture of ethylene and propylene oxides, containing a mixed chain of ethylene oxide and propylene oxide, terminated by a hydroxyl group. Examples include C13 to C15 fatty alcohols condensed with 6 moles ethylene oxide and 3 moles propylene oxide, C13 to C15 fatty alcohol condensed with 7 moles propylene oxide and 4 moles ethylene oxide, C13 to C15 fatty alcohol condensed with 5 moles propylene oxide and 10 moles ethylene oxide or mixtures of any of the above.
  • Another group of non-ionic surfactants are commercially available as DobanolTM which is an ethoxylated C fatty alcohol with an average of 7 moles ethylene oxide per mole of fatty alcohol.
  • the non-ionic surfactant comprises alkyl polyglycosides (APG).
  • Alkyl polyglycosides are compounds having formula: R10(R20)b(Z)a, wherein R1 is a alkyl radical, having from about 1 to about 30 carbon atoms; R2 is an alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; and a is a number having a value from 1 to about 6 (the degree of polymerization).
  • alkyl polyglycosides are generally present as mixtures of alkyl polyglycosides having varying amounts of carbon atoms in the alkyl radical and varying degrees of polymerization.
  • the alkyl radical is generally referred to as having a range of carbon atoms (e.g. C4/22 referring to a range of alkyl radicals having from 4 to 22 carbon atoms) and the degree of polymerization is generally referred to as the average degree of polymerization of the mixture.

  • a log of the “Control” or input level of bacteria was calculated, and similarly a log value of the number of bacteria residuals in the samples containing the formulations under test was calculated.
  • the log reduction value was calculated by subtracting the residual bacteria of each formulation from the input value. The higher the value means more reduction of bacteria
  • composition 1 removes bacteria more efficiently compared to formulation A. From the examples it is evident that contrary to expectations, the use of a lower amount of a nonionic surfactant meant better cleaning of the food products.
