Description
DETERGENT COMPOSITION
This invention relates to a detergent composition and in particular to a detergent composition in paste form.
Detergent compositions in paste form are known for use in hand washing, personal washing and laundry washing applications. Detergent products in the form of powders and bars are well known for use in the washing of fabrics and generally are employed far more widely than detergent pastes for this particular application. However detergent pastes provide a suitable form of detergent product especially for washing applications in which the product is applied directly to the fabric to be washed. Furthermore detergent pastes may also be employed in which the detergent is dosed into a liquor to provide a solution wash as is the norm with detergent powders. Pastes therefore provide the consumer with a flexibility as regards the type of washing operation which may be employed.
It is desirable to ensure that the viscosity of the paste is such that the paste is not so pourable that significant wastage is encountered in a. direct application washing process and also that the paste is not so viscous that dispersibility and dissolution in a solution washing process become unacceptable if this flexibility of use is to be retained. Control of the viscosity of the paste to provide an optimum combination of characteristics is desirable.
WO 95/09224 discloses a fabric washing detergent composition in paste form containing a mixture of nonionic and anionic surfactant of the sulphate and sulphonate type. The problem addressed in this disclosure is to minimise changes in viscosity due to an increasing or variable salt content from the surfactant raw materials. WO 95/09224 also discloses that a relatively modest level of salt, 0.5% in the case of a paste composition containing long chain alkyl sulphate as the only anionic surfactant, may lead to an unacceptable decrease in the viscosity of the composition; thus the level of salt may affect the viscosity of the paste composition.This document discloses that 0.05 to Swt% of alkali metal and/or ammonium sulphate and/or chloride may be present in the composition together with the nonionic surfactant and alkyl benzene sulphonate and ether sulphate and/or alkyl sulphate surfactant.
Although control of viscosity is important, using a variety of surfactants or higher levels thereof may be undesirable on cost grounds particularly in markets where the detergent paste product sells primarily on the basis of its price.
We have surprisingly found that detergent pastes having acceptable viscosity characteristics may be obtained by including in the paste composition a hydratable builder salt at a level of more than 5% by weight of the composition without the need to necessarily employ a variety of surfactants in order to control the viscosity.
Accordingly a first aspect of the invention provides a detergent composition in paste form comprising an anionic surfactant in an amount of 5 to 40% by weight of the composition and a hydratable builder salt in an amount of more than 5% by weight of the composition wherein the level of the builder salt exceeds that of the anionic surfactant and the paste has a viscosity of 7 to 700Pa.s at a shear rate of ls-l.
Suitably any hydratable salt may be employed although it is preferred if the hydratable builder salt is selected from builders such as polyphosphates orthophosphates, tripolyphosphates, phosphates, tetraphosphates, pyrophosphates, carbonates and bicarbonates and the alkaline metal and ammonium salts of any of the foregoing.
Preferably the hydratable salt is present at a level of at least 10% and desirably at least 15% by weight of the composition. Suitably the level of the hydratable salt does not exceed 50% and preferably does not exceed 40% by weight of the composition and a level of not more than 30% is especially preferred.
In a particularly preferred embodiment, the hydratable salt comprises sodium tripolyphosphate and optionally sodium carbonate. Sodium tripolyphosphate is preferably present in an amount of 15 to 35% and preferably less than 30% by weight of the composition and, if present, the carbonate is suitably at a level of 1 to 12% especially 1 to 10% by weight of the composition.
As regards the anionic surfactant, any conventional anionic surfactant may be employed including linear or branched alkyl benzene sulphonate, alkyl sulphate, alkyl ether sulphate, alkane sulphonate, oleo in sulphonate, fatty acid monoglyceride sulphate, alkyl glycerol ether sulphate, acyl sarcosinates, salts of C6 to C20 fatty acids and rosin acids.
Suitably the anionic surfactant is present as an alkaline metal, alkaline earth metal or an ammonium or substituted ammonium salt.
Preferably the anionic surfactant comprises linear alkyl benzene sulphonate and optionally an alkyl ether sulphate.
These surfactants suitably have a C9 to Clsalkyl chain and in the case of the ether sulphate, from 1 to 10 and preferably 1 to 5 alkylene oxide and suitably ethylene oxide, residues.
The anionic surfactant may be incorporated as a preneutralised material or the acid form of the surfactant may be incorporated with a suitable quantity of alkaline material in order to effect the neutralisation of the acid.
Preferably the anionic surfactant is present at a level of 5 to 35%, more preferably 5 to 20% especially 10 to 20% by weight of the composition. Where the composition comprises an alkyl benzene sulphonate and an alkyl ether sulphate, the sulphonate is suitably present at a level of 8 to 20% and preferably 10 to 18% by weight of the composition and the sulphate is suitably present at a level of 1 to 6%, preferably 1 to 4% by weight of the composition. These levels represent a highly preferred embodiment of the present invention.
The combination of linear alkyl benzene sulphonate and alkyl ether sulphate is especially preferred as the tolerance of the detergent composition to calcium in the wash water may be improved and also suitable mildness characteristics may be obtained.
The level of surfactant in the composition is selected according to the performance criteria required and having regard to cost.
Suitably the level of builder salt exceeds the level of surfactant in the composition but is preferably less than 5:1, more preferably 1.1 to 2.5:1 builder salt to surfactant on a weight basis.
Other surfactants may be included in the composition as desired. Suitable other surfactants include nonionic, amphoteric and cat ironic surfactants which may be included in order to provide improved cleaning performance or other desirable properties.
If other surfactants are present, the detergent composition preferably contains nonionic surfactant, especially alcohol alkoxylates which desirably have a linear or branched alkyl chain having 9 to 15 carbon atoms and which have an average degree of ethoxylation of 1 to 15, preferably 1 to 10 for example 3 and 7. Nonionic surfactants may be employed in the composition in order to provide improved skin mildness characteristics.
The viscosity of the paste may be tailored according to local market requirements. Less viscous pastes may be provided by including water in the composition at a relatively high level such as at least 45% and, according to the viscosity required up to 75% by weight of the composition. The precise level may be selected according to the other components in the composition to provide a paste which has a viscosity of not less than 7Pa.s and suitably 7 to 100Pa.s.
Detergent pastes according to the invention having a higher viscosity may be produced by incorporating a solid material for example a filler. Suitable fillers include conventional inorganic fillers such as kaolin, silica, starch, bentonite, talc, clay, silicate and especially calcite. The amount of inorganic material included as a filler will vary according to the desired viscosity but generally will not exceed 15%, and or preferably not exceed 12% by weight of the composition. High viscosity compositions according to the invention suitably have a viscosity of more than 100 and up to 700Pa.s.
Preferably the detergent paste is formulated so that in use as a paste in a direct washing application, it has a pH of 8 to 11.5, preferably 9 to 11.
Compositions according to the invention may be prepared by incorporating the components of the composition into a batch mixer with agitation in order to provide a substantially homogeneous composition. For high viscosity pastes, a
Winkworth Z-blade mixer may suitably be employed and for lower viscosity compositions, for example below about 100Pa.s, a conventional batch mixer equipped with paddles may be employed.
Compositions according to the invention may comprise other ingredients conventionally found in detergent compositions, including fluorescors lather control agents or lather boosters as appropriate, dyes, perfumes and the like. This list is not intended to be exhaustive. All viscosities referred to herein are measured at a shear rate of ls- and all amounts and proportions and by weight unless otherwise specified.
The invention is illustrated by the following non-limiting
Examples.
Examples 1 to 6
Compositions as detailed in Table 1 below were produced by dosing the components into the batch mixer in the order listed in the Table with each component being incorporated into the mixture before the addition of the next component.
The process was conducted at about 400C and for Examples 1 to 5 was carried out in a three blade paddle mixer and for
Examples 6 and 7 was carried out in a Winkworth Z-blade mixer.
