Definitions

the present invention relates to a soap composition suitable for being transformed into particles or flakes which are readily soluble even in cold water.
washing agent compositions which contain, as components, soaps in partial or total substitution of synthetic surfactants for the washing of household laundry in washing machines or by hand.
a high density granule soap composition having an excellent solubility comprising a builder and a mixture of a sodium salt and a potassium salt of fatty acids, said fatty acids having a Dalican titre of 35°C or lower, preferably 30 to 20°.
the soap produced it has been found, surprisingly, that it is possible to obtain a considerable improvement in the physical properties of the soap produced, such that it is rendered suitable for transformation into thin flakes and, at the same time, has outstanding properties of solubility in cold water at temperatues between 10°C to 40°C, by using mixtures of fats or oils or fatty acids having a Dalican titre of fatty acids comprised between 10°C and 20°C with the exclusion of 20°C, and saponifying such mixtures with sodium hydroxide.
Example 1 Composition of a sodium soap obtained from a common tallow/coconut oil mixture.
the flakes obtained from the soap according to the invention show outstanding physical properties of cohesion and are not susceptible to phenomena of pulverisation and breaking up or of excessive stickiness during the rolling and finishing stages and in their subsequent use in detergent powders.
compositions indicated above also allow drying of the soap to very low values of moisture content even below 5%, while the workability properties for obtaining flakes remain unchanged and the physical properties thereof are not adversely affected, so that they can also be used in products in which the components easily disintegrate in the presence of moisture.
soap flakes according to the invention particularly suitable for use in detergent compositions of the type described, for example, in EP-A-422449 by the same Applicant.
