Abstract
Built laundry bars containing fatty acid ester sulphonates are manufactured by a process which includes admixing with the other bar components a chlorine bleach (preferably hypochlorite) in an amount effective to bleach the fatty acidester sulphonate.
Description
SPECIFICATION
Bleaching detergent materials Fieldofinvention This invention relates to the bleaching of fatty acid ester sulphonates for inclusion as a detergent material in built laundry bars. Built laundry bars, which are usableforfabricwashing and cleaning surfaces, are a widely used product in a number of countries.
The provision of fatty acid estersulphonates (FAES) with a good colour is a necessary requirement in the manufacture of a commercial product. This invention is directed to improving the colour of FAES containing built laundry bars to insure such products have a good final colour.
Commercial built detergent bars contain detergent active and detergent builder materials together with optional components, for example abrasives, fillers, perfumes, alkaline salts, for example silicates, and bleaching agents.
General description ofinvention The invention provides a process forthe manufacture of built laundry bars containing from about 5% to about 45% by weight of non soap detergent active material and from about 5% to 60% by weight of detergent builder. The laundry bars will contain at least about 5% by weight of fatty acid (C8 to C22) ester (C1 to C4) sulphonate as all or part of the detergentactive material. In this manufacturing procedure the fatty acid ester sulphonic acid is neutralised and then mixed with the other components,the characterising feature ofthe invention being the addition of an effective bleaching amount of a chlorine bleach with the other components.
The chlorine bleach is preferably an alkali metal or alkaline earth metal hypochlorite, especially sodium hypochlorite butalsothe lithium, calcium or magnesium salt; an N-chloroamine such astrichlorocyanuric acid (TCCA) or sodium dichloroisocyanurate dihydrate (Na DCCA 2H2O); or gaseous chlorine passed into the alkaline mass of mixed components. Two or more different chlorine bleaches may if desired be employed in the process ofthe invention.
As already indicated, hypochloride bleaches are especially preferred. In general a concentrated solution of sodium hypochlorite is preferably used because the amount of water introduced into the product istherebykepttoaminimum. For example, sodium hypochlorite solution is available commercially in some countries at 14% and 10% w/wconcentrations: the former, which has an available chlorine content of 14.5%, is preferred for use in the present invention.
The use of a solid hypochlorite, for example, calcium hypochlorite (bleaching powder), is also feasible to obtainbieaching. However,theuseofthismaterial or the analogous magnesium salt introduces hardness ions into the composition with consequent reduction in the effectiveness of the builder component in the composition.
Fatty acid ester sulphonates have the general formula R1CH(SOM)COOR2 where R1 is a branched, for example, derived from petroleum, or straight chain alkyl group containing from 8 to 22 carbon atoms and R7 is an alkyl group containing 1 to 4 carbon atoms. M isacation providingwatersolublepropertiesforthe detergent active and will usually be selected from ammonium, potassium and sodium. Preferably the level offatty acid estersulphonate in the product bar is above about 10% byweightand more preferably above about 20% by weight.
The process ofthe invention may be utilisedto manufacture bars ofwhich fatty acid ester sulphonate forms eitherthe whole or only part ofthe detergentactive system. Other detergent-active materials that may advantageously be present in bars manufactured in accordance with the invention are listed below under "Components".
The quantity of chlorine bleach utilised is designed to provide optimum bleaching of the ester sulphonate detergent active without providing a residual quantity in the product: the presence of bleach-sensitive adjuncts, for example, fluorescers, requires that there be no free bleach species remaining in the product.
The quantity of bleaching agent required will of course depend on the bleaching agent selected. For sodium hypochlorite (14.5% available chlorine), the preferred amount is from 2 to 46% by weight based on the fatty acid ester sulphonate, for example about 24% by weight. For solid calcium hypochlorite (55% available chlorine), the preferred amount is from 0.4 to 15% by weight, for example, from 9 to 12.5% by weight. For trichlorocyanuric acid (90% available chlorine), the preferred amount is from 0.3 to 8% by weight, for example, from 3.5% to 5.5% by weight If more dilute solutions or impure samples having lower available chlorine contents are used, correspondingly larger amounts will be required.
The product prepared bythis process required less pigment because of its lighter colour and bar odour is reduced; the feel characteristics of the product in use are satisfactory.
Prior literature
The bleaching of fatty acid ester sulphonate materials for use in detergent formulations is the subject of a number of literature disclosures. These disclosures are, however, directed to the bleaching of the sulpho- nic acid or sulphonate as a separate component for a detergent composition before the detergent material is mixed with othercomponents. Documentswhich disclose the bleaching of neutralised fatty acid ester sulphonate with hypochlorites are GB 2141 706, GB 2 089793B,US3354187,GB1050534,US3485856,GB 1 063 431, DE 1 234709 and US 3142691 (Henkel).
Components
Detergent-active and builder components are well charncterised in detergent bartechnology. These components are described in "Surface Active Agents" by Schwartz and Perry (lnterscience 1949) and Volume
II by Schwartz, Perry and Berch (Interscience 1958).
The detergent-active materials usable in the present invention in admixture with fatty acid ester sulphon- ates may be found in the general classes of anionic, nonionic, amphoteric, betaine and zwitterionic actives. Specific examples of detergent-active materials arelinearalkyl benzenesulphonates,alkanesulphonates, secondary alcohol sulphates, branched alkyl benzene sulphonates, alkyl sulphates, olefin sulphonates, monocarboxylic acid salts, ethoxylated alcohols and above all, primary alcohol sulphates.
Especially preferred for use in bars prepared according to the invention are C8-C22 primary alcohol sulphates and linear or branched C8-C15 akylbenzene sulphonates.
Examples of builder components are: water soluble phosphate salts, for example, sodium tripolyphosphate, pyrophosphate and orthophosphate; water soluble carbonates, for example, sodium carbonate, organic builders, for example, sodium nitrilotriacetate, sodium tartrate,trisodium carboxymethyl oxysuccinate, sodium oxydisuccinate, sodium sulphonated long-chain monocarboxylic acids; and ion exchange materials, for example, aluminosilicates.
Other ingredients, for example, silicates such as sodium alkaline silicate, starch, sodium carboxymethyl cellulose, colouring materials, fluorescers, opacifiers, germicides, enzymes, perfumes, bleaching agents and fillers, for example, sodium sulphate, talc, calcite and bentonite, may optionally be present.
