Definitions

  • the present invention relates to light duty cleaning compositions. Such compositions find particular utility in hand dishwashing processes.
  • EP 0181212 discloses a liquid detergent composition which comprises 4-20% of alkyl sulphate, 5-24% alkyl ether sulphate and 5-20% alkyl benzene sulphonate as the anionic surfactants, magnesium ions, 1-10% of an ethoxylated alcohol nonionic surfactant and 0.25-10%wt of a betaine.
  • Alkyl sulphate will be present in alkyl ether sulphate as obtained from commercial sources. Typical levels of alkyl sulphate in alkyl ether sulphate (3EO) are generally 15- 20%, whereas higher ethoxylates contain less alkyl sulphate. Commercially available alkyl ether sulphate (1EO) comprises some 38-44% alkyl sulphate.
  • the anionic surfactant can be viewed as a mixture of the alkyl benzene sulphonate and an alkyl ether sulphate prepared with low levels of ethoxylation in a typical ratio of at least 1:5.
  • acceptable light duty cleanin formulations particularly suitable for hand-dishwashing, can prepared without or with low levels of alkyl benzene sulphonate and with low levels of alcohol.
  • an aqueous, light duty cleaning composition comprising:
  • the level of alkyl benzene sulphonate in the composition is such that the weight ratio of the total of alkyl ether sulphate and alkyl sulphate (a) to alkyl benzene sulphonate is greater than 4:1.
  • the total of alkyl sulphate and alkyl ether sulphate (a) has an average ethoxylation value of less than 2.
  • Suitable average alkyl chain lengths are C 8 -C 16 , with lauryl being particularly preferred.
  • the alcohol ethoxylate (b) has a calculated H B of 10-20.
  • Suitable alkyl chain lengths range from C 8 - C 16 with C 10 -C n being particularly preferred.
  • the preferred degree of ethoxylation is such that the EO value is above 5, more preferably 7-15, most preferably 10.
  • amphoteric (c) is selected from the group comprising amine oxide, betaines and mixtures thereof.
  • a ido propyl betaines are particularly preferred. Typical levels of betaine range from l-5%wt. It is preferred that the overall level of amphoteric is above 1.5%wt.
  • Typical magnesium sources include sulphates at levels of 0.5-3%.
  • Typical ethanol levels are such that the composition comprises not more than 2%wt ethanol.
  • the compositions particularly those having less than 20% total anionic surfactant present, are essentially free of ethanol.
  • ethanol levels of around l%wt are preferred.
  • compositions according to the present invention conveniently comprise 0.5-3%wt of an C 8 -C 14 alkyl monoethanola ide, more preferably 0.9-2.0%wt of lauryl monoethanolamide.
  • compositions comprise 0.05-0.5% citric aci monohydrate as a buffer, 0.1-l%wt perfume and/or further minors selected from preservatives, lemon-juice and dyestuffs.
  • compositions comprise 10-14%wt or 20-27%wt in total of alkyl ether sulphate or alkyl sulphate: the lower levels being used for dilute compositions and the higher levels being used for concentrates.
  • the ratio of the total of the alkyl ether sulphate and alkyl sulphate to the betaine is 6-8:1,and the ratio of the alkyl ether sulphate and alkyl sulphate to the total ethoxylated nonionic surfactants present is also 6-8:1.
  • the ratio of the total of the alkyl ether sulphate and alkyl sulphate to the betai is 3-5:1 and the ratio of the total of the alkyl ether sulphate and alkyl sulphate to the total ethoxylated nonionic surfactants present is 2-4:1.
  • the ratios of the total anionic actives to the betaine and the ethoxylated nonionics i.e. the anionics comprise alkyl ether sulpha and alkyl sulphate substantially free of other anionic surfactant species.
  • compositions were prepared with formulations as shown in table 1 below.
  • AES lauryl ether sulphate with an average degree of ethoxylation of 1
  • Betaine is lauryl amido propyl betaine
  • LMEA lauryl monoethanolamide
  • Nonionic is C u/12/13 alcohol ethoxylate 10EO.
  • the minors were preservative, dyestuffs and lemon juice.
