Definitions
- the strongly alkaline material is selected from alkali metal, especially sodium, metasilicate, and mixtures thereof with other alkaline materials such as sodium hydroxide and potassium hydroxide. Normally, they will be incorporated at from 1% to 10%, typically around 5% by weight of the total composition.
- EP 28849-A (Unilever) describes non-aqueous built liquid detergent compositions which contain the combination of a specific copolymer and a strongly alkaline material, among examples of which are sodium carbonate, sodium hydroxide and sodium disilicate. The use of sodium metasilicate is not proposed.
- the liquids may optionally contain bleaches, with or without bleach precursors.
- Specified builders include sodium tripolyphosphate and zeolites. There is however no mention of the problem to which the present invention relates, nor is a solution thereof suggested.
- the aluminosilicate builder may be selected from crystalline or amorphous materials, for example having the general formula: Na Z (AlO2) Z (SiO2) Y x H2O wherein Z and Y are integers of at least 6, the molar ratio of Z to Y is in the range from 1.0 to 0.5, and x is an integer from 6 to 189 such that the moisture content is from about 4% to about 20% by weight (termed herein, 'partially hydrated').
- This water content provides the best rheological properties in the liquid. Above this level (e.g. up to about 28% by weight water content), the water level can lead to network formation. In conventional dispersions, below this level (e.g.
- Nonionic detergent surfactants are well-known in the art. They normally consist of a water-solubilizing polyalkoxylene or a mono- or di-alkanolamide group in chemical combination with an organic hydrophobic group derived, for example, from alkylphenols in which the alkyl group contains from about 6 to about 12 carbon atoms, dialkylphenols in which each alkyl group contains from 6 to 12 carbon atoms, primary, secondary or tertiary aliphatic alcohols (or alkyl-capped derivatives thereof), preferably having from 8 to 20 carbon atoms, monocarboxylic acids having from 10 to about 24 carbon atoms in the alkyl group and polyoxypropylenes.
- alkylphenols in which the alkyl group contains from about 6 to about 12 carbon atoms
- dialkylphenols in which each alkyl group contains from 6 to 12 carbon atoms
- primary, secondary or tertiary aliphatic alcohols or alkyl-capped derivatives thereof
- ethoxylated nonionics which are the condensation products of fatty alcohols with from 9 to 15 carbon atoms condensed with from 3 to 11 moles of ethylene oxide.
- condensation products of C11 ⁇ 13 alcohols with (say) 3 or 7 moles of ethylene oxide may be used as the sole nonionic surfactants or in combination with those of the described in the last-mentioned European specification, especially as all or part of the liquid phase.
- surfactants which may be used include alkali metal soaps of a fatty acid, preferably one containing 12 to 18 carbon atoms.
- Typical such acids are oleic acid, ricinoleic acid and fatty acids derived from caster oil, rapeseed oil, groundnut oil, coconut oil, palmkernal oil or mixtures thereof.
- the sodium or potassium soaps of these acids can be used.
- soaps can act as detergency builders or fabric conditioners, other examples of which will be described in more detail hereinbelow. It can also be remarked that the oils mentioned in this paragraph may themselves constitute all or part of the liquid phase, whilst the corresponding low molecular weight fatty acids (triglycerides) can be dispersed as solids or function as structurants.
- compositions according to the present invention preferably also contain one or more other functional ingredients, for example selected from other detergency builders, bleaches and (for hard surface cleaners) abrasives.
- the class of inorganic builders comprises various phosphate, carbonate, silicate and borate materials, particularly the alkali-metal salt forms. Mixtures of these may also be used.
- Suitable bleaches include the halogen, particularly chlorine bleaches such as are provided in the form of alkalimetal hypohalites, e.g. hypochlorites.
- the oxygen bleaches are preferred, for example in the form of an inorganic persalt, or a peroxy acid compound.
- Suitable persalt bleach, compounds are alkalimetal peroborates, both tetrahydrates and monohydrates, alkali metal percarbonates, persilicates and perphosphates, of which sodium perborate is preferred.
- composition contains abrasives for hard surface cleaning (i.e. is a liquid abrasive cleaner), these will inevitably be incorporated as particulate solids.
- abrasives for hard surface cleaning i.e. is a liquid abrasive cleaner
- these will inevitably be incorporated as particulate solids.
- They may be those of the kind which are water insoluble, for example calcite. Suitable materials of this kind are disclosed in the applicants' patent specifications EP-A-50,887; EP-A-80,221; EP-A-140,452; EP-A-214,540 and EP 9,942, which relate to such abrasives when suspended in aqueous media. Water soluble abrasives may also be used.
- the solids content of the product may be within a very wide range, for example from 1-90%, usually from 10-80% and preferably from 15-70%, especially 15-50% by weight of the final composition.
- the components of the solid phase should be in particulate form and have an average particle size of less than 300 microns, preferably less than 200 microns, more preferably less than 100 microns, especially less than 10 microns.
- the particle size may even be of sub-micron size.
- the proper particle size can be obtained by using materials of the appropriate size or by milling the total product in a suitable milling apparatus.
- compositions are substantially non-aqueous, i.e. they little or no free water, preferably no more than 5%, preferably less than 3%, especially less than 1% by weight of the total composition. It has been found by the applicants that the higher the water content, the more likely it is for the viscosity to be too high, or even for setting to occur. However, this may at least in part be overcome by use of deflocculants, especially in relatively high amounts.
- a colloid mill to achieve a particle size of 0.1 to 100 microns, preferably 0.5 to 50 microns, ideally 1 to 10 microns.
- a preferred combination of such mills is a colloid mill followed by a horizontal ball mill since these can be operated under the conditions required to provide a narrow size distribution in the final product.
- particulate material already having the desired particle size need not be subjected to this procedure and if desired, can be incorporated during a later stage of processing.
- the gas evolution was measured as the cumulative volume released from 100g of product, after 1 day and 3 days.
- Example 1 The procedure of Example 1 was followed except that various alkaline materials were incorporated and the compositions consisted of: Zeolite 24% Sodium perborate monohydrate 15% Plurafax RA30 56% Alkaline material 5%
