Definitions

  • the present invention relates to a particulate laundry detergent composition that provides especially good detergency in the hand wash on both oily and particulate soils.
  • Conventional laundry detergent powders intended for the handwash contain a substantial level of anionic surfactant, most usually alkylbenzene sulphonate.
  • Anionic surfactants are ideally suited to the handwash because they combine excellent detergency on a wide range of soils with high foaming. For high levels of oily soil, it is desirable to have a high level of anionic surfactant in the formulation. Nevertheless, there remains a need to boost this oily soil removal performance.
  • alkylbenzene sulphonate surfactants are notoriously calcium-intolerant and the formulations require substantial levels of detergency builder (calcium builder).
  • the builder if water-soluble, also provides the necessary ionic strength and alkaline buffering to a pH at which the anionic surfactant can function most effectively.
  • the most commonly used water-soluble detergency builder is sodium tripolyphosphate.
  • Sodium carbonate is also often present and provides some measure of calcium building as well as alkalinity.
  • the present invention in its broadest content is therefore aimed at optimising oily soil removal using handwash detergent products containing high levels of anionic surfactant.
  • a subset of the invention is also aimed at solving the problem associated with the alkylbenzene sulphonates.
  • GB 1 570 128 discloses detergent compositions comprising from 4 to 40 wt% of a magnesium-insensitive surfactant (for example, alkyl ether sulphate, ethoxylated nonionic surfactant, amine oxide), from 13 to 40 wt% of sodium silicate, and from 5 to 50 wt% of a magnesium-selective detergency builder (for example, zeolite, sodium citrate, nitrilotriacetate, or calcite/carbonate).
  • a magnesium-insensitive surfactant for example, alkyl ether sulphate, ethoxylated nonionic surfactant, amine oxide
  • a magnesium-selective detergency builder for example, zeolite, sodium citrate, nitrilotriacetate, or calcite/carbonate.
  • JP 09 087 690A discloses a high-bulk-density granular detergent composition for machine wash use, containing alpha-olefin sulphonate (5 to 40 wt%), plus ethoxylated nonionic surfactant (1 to 15 wt%), zeolite (10 to 40 wt%), and crystalline and amorphous sodium silicates (0.5 to 10 wt%).
  • WO 96 41857A and WO 96 05283 A disclose laundry detergent compositions having a high surfactant to builder ratio, greater than 0.8:1 and generally greater than 1:1, but these products are preferably of low pH and do not contain especially high total surfactant levels or anionic surfactant levels.
  • the problem of increasing oily soil removal at high levels of anionic is solved by use of a non-calcium-binding or low-calcium-binding (non-calcium-building) buffer salt.
  • the problem associated with the alkylbenzene sulphonates is solved by use of a calcium- tolerant non-soap anionic surfactant in combination with the buffer salt.
  • the present invention provides a particulate laundry detergent composition suitable for the washing of textile fabrics by hand, which comprises: (a) more than 40 wt% of an anionic surfactant system;
  • composition of the invention is based on a calcium-tolerant non-soap anionic surfactant system, present at a very high level, plus a high content of inorganic salts consisting predominantly or wholly of non-builder alkaline buffering agent. Certain optional ingredients may also be present.
  • the composition of the invention contains a very high level - greater than 40 wt% - anionic surfactant. More than one anionic surfactant may be present. These may for example be selected from one or more of alkylbenzene sulphonates, primary and secondary alkyl sulphates, alkyl ether sulphates, alkyl olefin sulphonates, alkyl xylene sulphonates, dialkyl sulphosuccinates, fatty acid ester sulphonates, alkyl amide sulphates, sorpholipids, alkyl glycoside sulphates and alkali metal (e.g. sodium) salts of saturated or unsaturated fatty acids.
  • anionic surfactant may for example be selected from one or more of alkylbenzene sulphonates, primary and secondary alkyl sulphates, alkyl ether sulphates, alkyl olefin sulphonates, alkyl xylene
  • the subset of the present invention which solves the problem associated with the alkylbenzene sulphonates requires at least 40% of calcium-tolerant non-soap anionic surfactant to be present.
  • the total amount of anionic surfactant present is preferably at least 45 wt% and more preferably at least 50 wt%.
  • the preferred non-soap calcium tolerant anionic surfactant for use in the compositions of the present invention is alpha-olefin sulphonate.
  • alkyl ether sulphate (another non-soap calcium tolerant material) may be present as a co-surfactant, in an amount less than that of the alpha-olefin sulphonate.
  • a preferred surfactant system comprises alpha-olefin sulphonate and alkyl ether sulphate in a weight ratio of from 2:1 to 30:1, preferably from 5:1 to 15:1.
  • alkyl ethoxy carboxylate surfactants for example, Neodox (Trade Mark) ex Shell
  • fatty acid ester sulphonates for example, FAES MC-48 and ML-40 ex Stepan.
  • compositions of the invention contain at least 30 wt%, preferably at least 40 wt% of inorganic salts (b). However, they differ from conventional formulations in that at least 20 wt% (based on the whole composition) consists of a non-detergency building (non- calcium-building, i.e. non- or low-calcium-ion-binding) alkaline buffering agent (bl).
  • the preferred alkaline buffering agent (bl) is sodium silicate which also provides magnesium building (effective magnesium ion binding).
  • Sodium silicate is preferably present in an amount of from 20 to 55 wt%, more preferably from 25 to 55 wt%, still more preferably from 30 to 55 wt% and most preferably from 35 to 55 wt%.
  • the inorganic salts (b) may consist wholly of non-building material (bl) such as sodium silicate.
  • Suitable salts include sodium carbonate and sodium tripolyphosphate, each of which may suitably be present in an amount of from 5 to 40 wt%, preferably from 5 to 20 wt%.
  • the alkaline buffering agent (bl) may be non-poisoned sodium carbonate.
  • Sodium carbonate as a component of a calcite/carbonate builder system is a true calcium-binding builder.
  • the carbonate on its own i.e. without the calcite
  • crystal growth inhibitors e.g. low-medium MW polyacrylates
  • Sodium carbonate can also be deliberately poisoned so as to be low or non-calcium binding by inclusion in the formulation of, for example, a low level of sodium tripolyphosphate, so that it will not behave as a builder. The level of sodium tripolyphosphate must then be sufficient to poison the building of the carbonate.
  • sodium silicate may additionally be present as alkaline buffering agent, i.e. the alkaline buffering agent (bl) may comprise a combination of poisoned sodium carbonate and sodium silicate.
  • Sodium tripolyphosphate or other poisoning builder is present as a builder or additional salt (b2).
  • the amount of poisoned sodium carbonate present is preferably from 20 to 55 wt%, more preferably from 25 to 50 wt%, most preferably from 20 to 35 wt%; the amount of sodium silicate is preferably from 0 to 35 wt%, more preferably from 5 to 20 wt%; and from 0.1 to 20 wt% (e.g.
  • 1 to 20 wt%) preferably from 0.5 to 10 wt% ( e.g. 1 to 10 wt%) and more preferably from 0.5 wt% to 5 wt% (e.g. 1 to 5 wt%), of sodium tripolyphosphate is preferably present.
  • nonionic surfactant and/or fatty acid soap may be included in order to control foam.
  • the amount of these materials, in total, should not generally exceed 10 wt% and preferably will not exceed 5 wt%.
  • Preferred nonionic surfactants are the C 10 -C 16 aliphatic alcohols having an average degree of ethoxylation of from 1 to 10, more preferably the C 12 -C 15 alcohols having an average degree of ethoxylation of from 2 to 8.
  • compositions of the invention may also optionally contain up to 10 wt% of other beneficial ingredients.
  • Such ingredients are preferably selected from enzymes, antiredeposition agents, fluorescers, and perfumes, also bleaches, bleach precursors, bleach stabilisers, sequestrants, soil release agents (usually polymers) and other polymers.
  • At least two enzymes selected from proteases, lipases, amylases and cellulases are present.
  • Preferred embodiments of the invention are selected from proteases, lipases, amylases and cellulases.
  • a preferred composition according to the invention comprises:
  • (b2) optionally from 0 to 20 wt% of inorganic detergency builders and/or other inorganic salts;
  • (a2) optionally from 0 to 10 wt%, preferably from 2 to 10 wt% of alkyl ether sulphate;
  • An alternative embodiment of the invention, in which the non-building alkaline buffering agent is poisoned sodium carbonate, may be as follows:
  • (bl2) from 0 to 35 wt%, preferably from 5 to 20 wt%, of sodium alkaline silicate;
  • component (d) from 0 to 10 wt% of other detergent ingredients selected from enzymes, antiredeposition agents, fluorescers, and perfumes.
  • compositions of the invention may be prepared by any suitable process.
  • the choice of processing route may be in part dictated by the stability or heat-sensitivity of the surfactants involved, and the form in which they are available.
  • alpha-olefin sulphonate is robust, and is available in powder, paste and solution form.
  • Alkyl ether sulphate is more sensitive to heat, is susceptible to hydrolysis, and is available as concentrated (e.g. about 70% active matter) aqueous paste, and as more dilute (e.g. 28.5 wt%) solution.
  • ingredients such as enzymes, bleach ingredients, sequesverss, polymers and perfumes which are traditionally added separately (e.g. enzymes postdosed as granules, perfumes sprayed on) may be added after the processing steps outlined below.
  • Suitable processes include:
  • drum drying of principal ingredients optionally followed by granulation or postdosing of additional ingredients;
  • non-tower granulation of all ingredients in a high-speed mixer/granulator for example, a Fukae (Trade Mark) FS series mixer, preferably with at least one surfactant in paste form so that the water in the surfactant paste can act as a binder;
  • sodium alkaline silicate can be admixed in the form of solution, or as powder, or as sodium carbonate/sodium silicate granules, for example, Nabion (Trade Mark) 15 ex Rhodia.
  • the anionic surfactant consists of or comprises an alkylbenzenesulphonate surfactant
  • it is preferably made by a non-tower route (NTR) granulation process (i.e. not by spray-drying), e.g. using a VRV-type mixer and an aluminosilicate layering agent is incorporated together with sodium carbonate, preferably in light powder form.
