Definitions
- the invention relates to a builder system suitable for use in a cleansing agent, to a process for the manufacture thereof, and to a cleansing agent containing such a builder.
- Cleansing agents and more particularly (main wash) detergents contain a number of groups of raw materials. The most important among them are the surface-active substances or surfactants, which serve to reduce the surface tension of the water, and the builders, which serve to neutralize the hardness of the water. Often, such cleansing agents further contain bleaching agents for removing colored soil components through oxidation, and additives such as perfume, optical bleaches, corrosion inhibitors and the like.
- phosphates In the past, for reducing the hardness of the washing water, use was mainly made of phosphates. Although these phosphates exhibit optimum effectiveness in terms of detergency, the use thereof is less desirable with regard to eutrophication and excessive algal growth. Accordingly, alternatives to the use of phosphates have been searched for.
- Known alternative builders are nitrilotriacetate, ethylene tetraacetate, citrate and zeolites. Soda has also been used in detergents on account of its calcium-binding activity. The presence of soda in detergents leads to the formation of insoluble calcium carbonate, often designated as calcite.
- the mains water that is used in the washing process must first be softened on account of the negative influence of hard water on the cleaning power of the suds system.
- the hardness of the suds system is reduced by the activity of the builders. This improves the detergency.
- the fact is there appears to be a virtually linear relation between the logarithm of the residual hardness and the cleaning power. In the times when mainly phosphates were used, the residual hardness was approximately 0.01 o dH. At that value the negative influence of the calcium hardness is minimal.
- Soda could be an attractive alternative as a builder, since it is capable of reducing the residual hardness to the same level as was formerly achieved by the phosphates and other builders which are no longer desired for environmental reasons. Soda moreover does not have any disadvantages from an environmental point of view.
- the object of the invention is to provide a builder system that is based on soda, does not possess the disadvantages of the known agents and yet does give rise to a very effective seed formation.
- the invention accordingly relates to a builder system which is suitable for use in a cleansing agent, and in particular in a main wash detergent, comprising porous beads of soda, preferably at least partially hydrated soda, into the pores of which beads an aqueous solution of a soluble metal salt, in particular a calcium salt, has been incorporated with the aid of an additive.
- a builder system which is suitable for use in a cleansing agent, and in particular in a main wash detergent, comprising porous beads of soda, preferably at least partially hydrated soda, into the pores of which beads an aqueous solution of a soluble metal salt, in particular a calcium salt, has been incorporated with the aid of an additive.
- non-ionic surface-active substance non-ionic
- porous soda beads which preferably have an average particle size of between 0.2 and 1.0 mm.
- the porosity of the soda determined with mercury porosimetry, is such that 50 to 85 vol.% of the pores have a diameter of from 0.1 to 0.7 ⁇ m, while the rest of the pores substantially have a smaller diameter.
- the average pore size of the beads is preferably between 0.05 and 3 ⁇ m, more particularly between 0.1 and 0.7 ⁇ m.
- the impregnation of the soda beads with the, preferably saturated, salt solution in combination with an additive preferably takes place in such a manner that the metal ion content, drawn to the weight of the beads, is between 0.5 and 10 wt.% and more preferentially between 0.5 and 5 wt.%.
- This impregnation preferably takes place in such a manner that the volume of the liquid employed for impregnation is not more than the total pore volume of the soda beads. This provides the advantage that eventually a dry product is obtained which can be further processed in a main wash detergent in the conventional manner.
- a particularly effective method for impregnating soda beads with the aqueous salt solution consists in the use of an emulsion of the calcium-salt solution in a non-ionic surface-active substance, such as an alkyl ethoxylate (3 to 20 EO) or an alkyl(poly) glucoside (1 or more glucoside), as additive.
- a non-ionic surface-active substance such as an alkyl ethoxylate (3 to 20 EO) or an alkyl(poly) glucoside (1 or more glucoside
- an oil or another compound through the effect of which the aqueous solution of the metal salt is incorporated into the soda and which gives rise to rapid formation of small seeds in the washing water.
- the invention also relates to a method for manufacturing such builder particles, comprising impregnating porous beads of soda with an emulsion of a saturated solution of a calcium salt in a non-ionic surface-active substance, the amount of the emulsion being not greater than the pore volume of the soda beads.
- the invention also relates to a detergent comprising, in addition to the customary components, at least one builder system as described hereinabove.
- the main wash detergent comprises conventional components for powdered detergents, such as surfactants, optionally one or more other builders or additives such as bleaches, perfume, corrosion-inhibitors, anti-redeposition agents and the like.
- a powdered detergent comprises the builder system as described within the concept of the invention, optionally in combination with other conventional builder components, such as untreated soda, bicarbonate, NAS, zeolite, co(polymer) and the like, at least one surface-active substance (non-ionic and/or anionic), optionally bleachers, such as perborate, additives, such as magnesium stearate and sodium sulfate, as well as the so-called “minors”, optical white, perfume, anti-redeposition agents and corrosion-inhibitors.
- other conventional builder components such as untreated soda, bicarbonate, NAS, zeolite, co(polymer) and the like, at least one surface-active substance (non-ionic and/or anionic), optionally bleachers, such as perborate, additives, such as magnesium stearate and sodium sulfate, as well as the so-called “minors”, optical white, perfume, anti-redeposition agents and corrosion-inhibitors.
- a powdered detergent according to the invention comprises, on a weight basis, 10 to 50% surface-active substance, 25 to 90% builder system, at least partially consisting of the porous soda impregnated with the metal salt, 0 to 25% bleaching agent and further additives and minors in an amount which is dependent on the nature of the additives and minors, but which will generally not exceed 60%.
- the amount of the builder system according to the invention that can be utilized in the detergents varies from 2.5 to 50 wt.%, more particularly between 5 and 25 wt.%. The amount depends at least partly on the amount of metal ion present in the builder system.
