Definitions
- the present invention relates to a "builder" agent in a structured form consisting of a solution of alkali metal silicates rich in silicon atoms in Q 2 and Q 3 form , this solution being in the presence of a mineral product other inert with respect to silicate.
- This builder agent is intended for detergent compositions, in particular for powdered detergents, in particular for washing machines or dishwashers.
- the invention also relates to cogranules of hydrated alkali metal silicates and alkali metal carbonates.
- builder is understood to mean any active adjuvant which improves the performance of the surfactants of a detergent composition.
- the builder must have a so-called "softening" effect on the water used for washing. It must therefore eliminate the calcium and magnesium which are present in the water in the form of soluble salts, and in the stains of the linen in more or less soluble complex forms.
- the elimination of calcium and magnesium can be done either by complexation, in the form of soluble species, or by ion exchange, or by precipitation. If precipitation is involved, it must be checked to avoid encrustations on the laundry or on the elements of washing machines.
- This precipitation control is in particular obtained by water-soluble polymers having an affinity for calcium and magnesium.
- the builder adds to the emulsifying effect of surfactants vis-à-vis fatty stains a dispersing effect vis-à-vis "pigmentary" stains, such as metal oxides, clays, silica, various dusts, humus, limestone, soot.
- This dispersing effect is generally obtained thanks to the presence of polyanions, providing a high density of negative charges at the interfaces.
- the builder provides an ionic strength favorable to the functioning of the surfactants, in particular by increasing the size of the micelles.
- Silicates have long been regarded as good detergency builders, but are currently used less in phosphate-free compositions for washing machines.
- the silicates most used in this application are those having a SiO 2 / Na 2 O molar ratio of between 1.6 and 2.7.
- the concentrated commercial solutions are most often prepared from completely amorphous silicate called “glassy”, also called “water glass”.
- the concentrated silicate solutions are introduced by the detergent formulator into the aqueous suspension (slurry) containing the other constituents of the detergent.
- the slurry is then spray dried.
- this powdered silicate which contains only 19 to 22% by weight of associated water (relative to the finished product), has only weak builder properties.
- this powdered silicate in solution essentially generates monomeric silicic species of formula Si (OX) 4 , where X represents H or Na, having no builder effect.
- monomeric species can only re-associate with each other to form polyanions if the silicate concentration is at least 50 to 500 g / liter and this slowly.
- silicate concentrations as well as the slow polymerization kinetics of the monomeric species are not compatible with the conditions and the durations of washing in a washing machine.
- Patent application EP-A-450 989 describes a process for the preparation of granulates of hydrated alkali metal silicates by spraying water or an aqueous solution of alkali metal silicates on a moving bed of particles of hydrated metal silicates alkaline scrolling in a thin layer in a device of the rotating plate type at room temperature, possible densification and drying. These granules can be used as "builder" agents for detergent compositions.

- US-A-2,909,490 describes dry granular solid compositions combining sodium tripolyphosphate and certain silicate solutions; the amount of sodium tripolyphosphate represents at least 68.5% of the weight of said compositions expressed on a dry basis.
- detergency builders are mixtures of alkaline hydrated silica pigment and alkali metal carbonate and / or bicarbonate (US-A-3,886,079).
- silicon atoms in Q 2 and Q 3 form is a representation of the degree of association of the silicon atoms with each other;
- Q 2 means that each silicon atom participates in two -Si-O-Si- bonds, the two remaining bonds being a termination -Si-OX where X is an alkali metal or H;
- Q 3 means that each silicon atom participates in three -Si-O-Si- bonds, the remaining bond being a -Si-OX termination.

- This agent can be obtained by adsorption and / or absorption of a concentrated aqueous solution of alkali metal silicate with a SiO 2 / Na 2 O ratio of the order of 1.6 to 3.5 rich in species Q 2 and Q 3 on said inorganic support, said support being present in an amount such that the amount of water remaining associated with the silicate corresponds to a weight ratio of water remaining associated with the silicate / silicate expressed in dry matter greater than or equal to 40/100.
- the support generally represents from 55 to 95% of the weight of said agent expressed in dry terms.
