Definitions

  • THE PRESENT INVENTION relates to bleaching and cleaning compositions containing hypochlorite and in particular to thickened bleach compositions, that is compositions having an increased viscosity as compared with straight aqueous solutions of alkali metal hypochlorite.
  • Thickened bleach compositions have a number of advantages over unthickened bleach compositions in that the more viscous compositions adhere more readily and for a longer time to vertical and inclined surfaces than do the unthickened compositions.
  • the performance of thickened bleach compostions is therefore superior to that of unthickened bleach compositions for vertical and inclined surfaces such as are found in lavatory pans, urinals, drains, waste pipes and the like.
  • thickened bleach compositions for example compositions having viscosities at 25°C of greater than 10 dm2/s, by the addition of suitable thickening agents. Viscosity can be further enhanced by the inclusion in such compositions of other components, for example caustic alkali, alkali metal salts.
  • British Patent Specification No 1,329,086 describes thickened aqueous alkali metal hypochlorite compositions which contain in addition to the hypochlorite, an alkali metal salt of a C8 to C18 fully saturated fatty acid and a hypochlorite-soluble surface active agent, the latter being exemplified by an amine oxide containing a C8 to C18 alkyl group.
  • the amine oxides described in the specification are those commercially available which are derived from naturally occuring C8 to C18 fatty acids, for example coconut acids, lauric acid and myristic acid.
  • British Patent Specification No 2,051,162A describes thickened aqueous alkali metal hypochlorite compositions which contain, in addition to the hypochlorite, an amine oxide and an alkali metal alkyl sulphate.
  • British Patent Specification No 2,003,522A describes thickened aqueous alkali metal hypochlorite compositions which contain a C8 to C20 branched chain amine oxide or a mixture of such amine oxides with or without the presence of an alkali metal salt of a fatty acid.
  • the amine oxide used to produce the data given in Table C consisted of a mixture of amine oxides with the following structural formulae:
  • the C13 amine oxide used in the formulations shown in Table C consisted of 50% amine oxides with structure (a), 40% with structure (b), and 10% with structure (c).
  • a thickened bleach composition of enhanced viscosity comprises water, an alkali metal hypochlorite and a thickening agent comprising a mixture of straight chain C14 amine oxide with a mixture comprising branched chain and straight chain C15 amine oxides.
  • R2 and R3 are preferably selected from lower ie C1 to C4 alkyl radicals, more preferably each of R2 and R3 being methyl.
  • the thickening agent comprises 10 to 60% w/w, more preferably 20 to 40% w/w of straight chain C14 amine oxide.
  • the C15 amine oxide component of the thickening agent preferably comprises at least 25 % w/w of branched chain material, more preferably at least 40% w/w, most preferably 45 to 55 % w/w.
  • compositions of the invention Over a range of concentrations the compositions of the invention have unexpectedly enhanced viscosities compared with the following prior art systems: (a) C15 amine oxide alone, (b) a mixture of straight chain C15 amine oxide and straight chain C14 amine oxide, and (c) a mixture of straight chain C14 amine oxide with a mixture of C13 branched and straight chain amine oxides.
  • This is graphically illustrated by the non-linear appearance of Figure 1 accompanying this specification when compared with Figures A, B and C.
  • the enhanced viscosity provided by the compositions of this invention has the considerable advantage that appreciably less thickening agent is required to achieve a commercially acceptable viscosity than is the case with prior art compositions.
  • compositions of this invention may also contain an alkali metal salt of a fatty acid, for example sodium laurate, as an additional component to aid thickening.
  • an alkali metal salt of a fatty acid for example sodium laurate
  • thickened bleaches according to this invention can contain additional components frequently incorporated in such compositions including caustic alkali, alkali metal salts, perfume and colourants.
  • the bleach compositions of this invention preferably contain an amount of available chlorine in the range 1 to 15%, preferably 5 to 10% by weight.
  • compositions of this invention preferably have a viscosity of at least 10 ⁇ 5m2s ⁇ 1 at 25°C, measured with a Brookfield RT viscometer using a No 3 spindle at 100 rpmin, and a cloud point in excess of 40°C.
  • the C15 amine oxides had the following structural formulae:
  • the mixture of C15 amine oxides used in the compositions of Table 1 comprised 50% amine oxide with structure (a), 40% amine oxide with structure (b), and 10% structure (c).
  • compositions 1 to 3 are according to this invention and compositions D and E are comparative compositions according to the prior art.
  • compositions F and G were prepared identical to those shown in Table 1 except that each additionally contained 0.05 wt% sodium laurate.
  • the compositions and their viscosities and cloud points are shown in Table 2, compositions F and G again being comparative compositions not according to the invention.
  • Figure 2 is a plot of the viscosities of these five compositions against their C15 amine oxide content, again illustrating the enhanced viscosity effect.
