Definitions

  • This invention relates to thickened liquid bleach compositions which may be suitable for sale and use as a domestic bleach.
  • Pourable domestic bleach is frequently thickened by including one or more surfactants which, in the presence of electrolyte, act to thicken the solution rendering it more viscous than water. Thickening of a pourable domestic bleach helps the user to control dispensing of the composition and retards drainage from surfaces to which it is applied.
  • This invention relates to such compositions which include surfactant and electrolyte to increase the viscosity.
  • the compositions of the invention may be pourable or may be even more viscous so as not to be poured easily.
  • a domestic bleach needs to be adequately stable so that a substantial proportion of the bleaching agent survives during storage between manufacture and use.
  • Prior to this invention commercial liquid bleach products have frequently utilised hypochlorite as bleaching agent.
  • any attempt to make a surfactant-thickened, alkaline domestic liquid bleach product using hydrogen peroxide as the bleaching agent would encounter the potential problem that the thickening of the solution would require the presence of some electrolyte but that this electrolyte would serve to accelerate decomposition of the peroxide.
  • a liquid bleaching composition comprising an aqueous alkaline solution containing hydrogen peroxide, a stabiliser therefor, electrolyte other than surfactant, and surfactant selected from:
  • a surfactant as specified above is advantageous in achieving thickening with a fairly low electrolyte concentration. This may make it possible for the electrolyte to be provided by ions which are in the composition for other reasons, without deliberate addition of salt for the sole purpose of enhancing ionic strength. Apart from considerations of peroxide stability, a benefit of a low electrolyte concentration is a reduced tendency for the product to leave streaks on a surface which is cleaned with it.
  • the nonionic/amphoteric surfactant is an amine oxide surfactant, preferably a trialkyl amine oxide with one long chain alkyl of 8 to 20 carbon atoms and two alkyl groups of 1 to 4 carbon atoms.
  • the weight ratio of amine oxide:alcohol sulphate is preferably in the range from 82:18 to 65:35; better 80:20 to 65:35, even better 80:20 to 70:30.
  • Alkane sulphonate is preferred over alcohol sulphate because the viscosity is less sensitive to changes in the composition, so making it easier to produce an end product with repeatable viscosity.
  • the weight ratio of amine oxide to alkane sulphonate (when this is used) is preferably in the range from 80:20 to 50:50 or better 65:35, and preferably in the narrower range from 70:30 to 65:35.
  • the total concentration of surfactant may lie in a range from 0.75 to 6% by weight based on the whole composition and may lie in the narrower range from 0.75 to 3%, especially if the composition is pourable. Concentrations above 6% by weight might be used but are less preferred.
  • the electrolyte concentration in a composition of this invention may be such that the total amount of salts other than surfactant is not more than 7% by weight, better not more than 5% or 3%.
  • the electrolyte level may be such as to give a concentration of electrolyte in the range 0.05 to 0.30 molar, preferably 0.1 to 0.2 molar. Once again higher concentrations may be used but are less preferred.
  • a sequestering agent may be used in an amount from 0.01 to 1% by weight. This is approximately 1.5 x 10 ⁇ 4 to 2 x 10 ⁇ 2 molar.
  • a separate stabilising agent to counteract manganese may be a phosphate salt used in an amount from 0.5% up to 4% by weight, preferably 1 to 3% (reckoned as anhydrous salt). Tetrasodium pyrophosphate may be used as such a salt.
  • colloidal hydrous stannic oxide Another possible stabilising agent which we have found to be effective in alkaline solution against decomposition caused by transition metals including both iron and manganese, is colloidal hydrous stannic oxide.
  • This stabilising agent is preferably formed in-­situ in the solution as the product of hydrolysis of a soluble tin compound.
  • Various tin compounds can be added to the solution to undergo hydrolysis to form the stannic oxide, including tin sulphate, sodium stannate, tin dichloride and tin tetrachloride.
  • Suitable concentrations of tin compound in the composition may lie in the range from 10 ⁇ 4 molar to 10 ⁇ 2 molar, preferably 3 x 10 ⁇ 3 to 6 x 10 ⁇ 3 molar.
  • the quantity of tin compound should not be substantially greater than necessary, since excess of it can itself cause peroxide decomposition.
  • An optimum concentration of the tin compound (or any stabiliser) can be determined by making test solutions with various concentrations of the stabiliser and analytically determining the amount of hydrogen peroxide remaining after a period of storage.
  • An appropriate viscosity for a pourable composition having the appearance of a thick liquid is a dynamic viscosity in the range from 40 to 250 centipoise (0.05 to 0.25 Pa.sec), preferably about 100 centipoise (0.1 Pa.sec). More viscous liquids for example with viscosity in the range from 250 to 1000 centipoise or more are also within the scope of the invention.
  • compositions of this invention are generally aqueous, they will usually have specific gravity close to unity. Consequently values of kinematic viscosities (in stokes) will be numerically approximately the same as values of dynamic viscosity (in poise). Dynamic viscosities expressed in Pascal.sec will be approximately 1000 times kinetic viscosities expressed in m2.sec ⁇ 1.
  • the pH of the solution is preferably in the range from 8.0 to 10.5, better 8.5 to 9.8 or 10.0.
  • a phosphonate stabiliser it is further preferred that the pH is in the narrower range from 9.2 to 9.8, while with colloidal stannic oxide as stabiliser it is preferable to use a slightly lower pH in the range from 8.7 to 9.3.
  • a buffer may be included to maintain pH at the desired value, but this may not be necessary.
  • a phosphate, if present, will give a buffering action.
  • Another compound which may be used for this purpose is borax.
  • the concentration of hydrogen peroxide in compositions of this invention desirably lies in the range from 1 to 15% by weight preferably 2 to 10% by weight.
  • Formulations were prepared containing the constituents set out in Table 1 below. The compositions were stored in plastic bottles at 37°C. At intervals aliquots were removed and titrated with potassium permanganate to determine the level of hydrogen peroxide remaining. Results are included in Table 1.
  • Example 1 The procedure of Example 1 was repeated, using formulations with the same amounts of hydrogen peroxide, surfactant, perfume and dye.
  • Various tin compounds were used at a concentration of 6 x 10 ⁇ 3 molar, both with and without 3.0% borax decahydrate. Glass bottles were used, which are somewhat detrimental to stability. In every case pH was 9.6 initially. Proportions of hydrogen peroxide remaining after 28 days were:- SnCl2 with borax 68% Na2SnO3 with borax 47% SnSO4 with borax 45% Na2SnO3 without borax 96% SnCl4 without borax 68%
  • the thickening systems used various constituents and varied both in the properties and total amounts of materials employed.
  • the thickening systems contained tallow dimethylamine oxide (AO) together with sodium lauryl sulphate (SLS), or sodium alkane sulphonate (SAS), which was a secondary alkane sulphonate derived from an n-alkane mixture which is principally C13 to C18.
  • AO tallow dimethylamine oxide
  • SLS sodium lauryl sulphate
  • SAS sodium alkane sulphonate
  • Viscosities of the formulations were measured using a Ubbelohde capillary viscometer. The results obtained are shown in the accompanying Figures.
  • a number of formulations were prepared using as surfactant a linear alkyl ether sulphate of general formula: R(OC2H4) n OSO3 Na where the alkyl group R was C12 and C13 linear alkyl groups, and n had an average value of 3.
  • Some of these formulations included a phosphonate stabiliser according to EP 9838.
  • Others used stannous chloride which hydrolysed in - situ to colloidal hydrous stannic oxide.
  • Peroxide stability was monitored, as in Example 1. Viscosities were determined using a Haake RV2 roto-viscometer at a shear rate of 21sec ⁇ 1 which is appropriate for determining viscosities of pourable domestic bleach products.
  • the formulations were as follows:
  • alkyl ether sulphate and sodium chloride are set out in the following Table.
  • Sodium chloride 4.5% 7% 6.5% 6.5%
  • Phosphonate stabiliser according to EP 9839 0.15% 0.15% 0.15% - Stannous chloride dihydrate - - - - 0.14% H2O2 remaining after 5 weeks at 37°C 75% 72% 71% 79% 80% Viscosity (cP) 15 200 600 100 100 100
  • Alkaline solutions of hydrogen peroxide were prepared containing surfactant, sodium chloride and stannic chloride which hydrolysed to colloidal hydrous stannic oxide.
  • surfactant combinations Two surfactant combinations were used.
  • the quantities of surfactant and sodium chloride were such as to give viscosities well in excess of that preferred for a pourable "thick liquid” type of bleach product. Smaller quantities could be used to give a "thick liquid” type of bleach product.
  • Stannic chloride was used at a concentration of 2.3 x 10 ⁇ 3 molar.
  • One surfactant system consisted of 4.5% by weight of C12-C14 alkyl dimethyl amine oxide and 4.5% by weight sodium lauryl sulphate. This was used with a sodium chloride concentration of 9% by weight.
  • the second surfactant system consisted of 5% by weight of C11-C15 secondary alcohol ethoxylated with average 3 ethylene oxide residues, and 5% by weight of sodium lauryl sulphate. This combination was used with 3.37% by weight sodium chloride.
