Description

FOAM FORMATION COMPONENT TECHNICAL FIELD This invention relates to a foaming composition useful in any application where foam is required, such as cleaning compositions, pharmaceutical compositions, food and beverages.

BACKGROUND OF THE INVENTION Foaming is useful in several applications for different reasons. In detergents, it is known that specific surfactants provide foaming in the washing water. It is desirable that the formation of foam occurs easily and that the foaming has the desired duration. For example, it is desirable that the effervescence or foam occurs immediately after contact with water, and that it be stable or continuous during use. In addition, to maximize the foaming, foaming or effervescence of these techniques during use in contact with water, such contact with water or moisture should be avoided during manufacture or storage.

Components that react with each other upon contact with water to produce effervescence are known detergent ingredients. For example, WO 92/18596 discloses detergents comprising citric acid and sodium carbonate salt mixed as an auxiliary to improve the solubility of the detergent. Effervescence systems are well known in pharmaceutical or agricultural applications, for example as described in GB-A-2, 184,946. The inventors have discovered that an effervescence component capable of providing a gas can be used to produce foaming, when used in a specific combination with a surfactant component capable of reducing surface tension, so that controlled, rapid foaming is achieved. and improved. After contact with water, the components comprising the specific effervescence component and the specific surfactant component chemically form microbubbles, preferably with an average diameter of 200 microns or less. The inventors have found that the formation of this microbubbles allows improved control of foaming, foaming or effervescence, and that it results in improved foaming stability. For example, foam that forms quickly and stable or long lasting can be obtained. It has also been found that the components of the invention provide improved effervescence and supply and dissolution of the component or product comprising the component.

In addition, it has been found that these components are very stable after storage.

FORM OF COMPOSITIONS The cleaning compositions, which contain the component, can be made by a variety of methods, including dry blending, extrusion, compression and agglomeration of the various components contained in the detergent composition. The foaming component of the invention can be presented in the compositions for cleaning as a separate component of the composition, or it can be part or added to other components or compounds of the compositions. Cleaning compositions can have a variety of physical forms, including granules, extrusion tablets or bars. Cleaning compositions are particularly so-called granular concentrated detergent compositions adapted to be added to a washing machine by means of a supply device placed inside the drum of the washing machine with laundry load. The average particle size of the base composition of the granulated compositions according to the invention can be 0. 1 mm to 5.0 mm, but preferably no more than 5% of the particles should have a diameter greater than 2.5 mm, or even 1.7 mm and no more than 5% of the particles should have a diameter less than 0.15 mm. The term average particle size, as defined in the present invention, is calculated by screening a sample of the composition in a number of fractions (typically 5 fractions) in a series of Tyler sieves. The heavy fractions obtained from the described process are graphed against the opening size of the sieves. The average particle size is taken to have an aperture size through which 50% by weight of the sample passes. The bulk density of the granular detergent compositions containing the particulate composition according to the present invention is typically at least 500 g / liter, or even 650 g / liter at 1200 g / liter, most preferably 850 g / liter . The volumetric density is measured by means of a simple funnel-cup device consisting of a conical funnel rigidly molded on a base and provided with a butterfly valve at its lower end to allow the contents of the funnel to be emptied into a cylindrical cup aligned axially below the funnel. The funnel is 130 mm high and has internal diameters of 130 mm and 40 mm in its respective upper and lower extremities. It is mounted in such a way that the lower extremity is 140 mm above the upper surface of the base. The cup has a total height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml. To carry out a measurement, the funnel is filled with dust by manual emptying, the butterfly valve is opened and the powder is allowed to overfill the cup. The full cup is removed from the frame and excess powder is removed from the cup by passing a straight edge instrument, eg, a knife, along the top edge. The filled cup is then weighed and the value obtained for the weight of the powder is doubled to provide a global density in g / liter. Equal measurements are made as required. The composition is preferably soluble in cold water, ie the composition is easily dissolved / dispersed in water at a temperature between 0 ° C and 32.2 ° C, preferably between 1.6 ° C and 10 ° C.
