Description

PERSONAL SUPERGRASA CLEANING BAR CONTAINING ALKYL POLYGLUCOSIDE BACKGROUND OF THE INVENTION: This invention relates to a process for manufacturing supergrass soap bars. Carra-shaped soaps have been used for a long time for cleaning purposes. Those skilled in the art use the term "soap" to designate the reaction product of a carboxylic acid with a base, commonly a carbonate or metal hydroxide. The resulting salt has a polar hydrophilic and a non-polar lipophilic end that facilitate the removal of oils and other non-polar materials from the skin or other surfaces in the presence of water. The bars of soaps by custom are prepared by molding / casting or by refining / extrusion. Molded or emptied soaps are prepared by reacting an appropriate grease, oil or carboxylic acid with a base in the presence of water to form soap, spilling the melted soap containing approximately 30- of water into a structure or mold, allowing the soap cools and solidifies, and separating soap that has approximately 20 to 25% water by weight in the form of a bar. Experts in the manufacture of soaps know that carboxylic acid, hereinafter referred to as fatty acid is readily available as a commercial item. The fatty acid can also be obtained from a fat, such as oil or tallow, from an oil, such as oil, coconut oil, palm oil, palm kernel oil, or olive oil, or from combinations of fats and oils.Greases and oils are constituted in a substantial part of glycerides of chains of variable lengths, which are glycerol esters (glycerin) and fatty acids.Alternative conditions, and in the presence of heat, glycerides constituents of fats and oils are broken down to form salts of fatty acids, also known as soaps, and glycerin Refined / extruded soap bars are produced by subjecting the neutralized soap to several finishing steps that alter the crystalline soap matrix from the omega phase, as it is formed in soap bars in molding / casting, to the beta phase.Before conversion, the soap first dries from a moisture level of about 30 to a level in the rang or from about 10 'up to about 14. After drying, the soap is generally sent to a mixer of the simple paddle type where a variety of additives are introduced. From this mixer the soap is then sent directly to a refiner or optionally to a three-roll mill and then to the refiner.

Both the refiner and the mill subject the soap to compression and to an intense cutting action that tends to. Orient the soap crystals and convert most of the soap to the beta phase. After refining, the soap is compressed into a coherent, dense form in an extrusion operation that forms solid portions that are suitable for printing on bars. The drying step is necessary to eliminate the "sticky" texture and excessive flexibility of the soapy mass that commonly exists at higher moisture levels. In the production of extruded bars, drying from about 10; up to about 147: moisture is necessary to allow the soap mass to be processed by the finished equipment. Commercial drying is carried out by several different methods. One method employs a water-cooled roller in combination with a second feeder roller to spread the neutralized soap, melted into a thin and uniform layer. The cooled soap is then separated from the roll to form pieces and dried at a specific moisture level in a drying tunnel. The pieces of soap that already have a low humidity level (approximately 10 to 11) are additionally dried by the repeated passage of the pieces through steel rollers cooled by water, closed (ie, three roller mill) in the process known as grinding described above. A relatively modern technique for drying soap is known as secai: p aspersion. This process directs molten soap to the top of a tower by means of spray nozzles. The sprayed soap hardens and then dries in the presence of a hot air stream. It can be applied empty to facilitate the elimination of water. Although the typical moisture level of the extruded soap bars is maintained in the range of about 10 * to about 14, the extruded bar of soap contains more than 14% moisture. A regular soap may have a tendency to degrease the skin due to its slightly alkaline character. This can be a problem, particularly for people with dry skin. The incorporation of a superfatting agent containing a free fatty acid in a bar of soap imparts better tactile properties to the composition by eliminating the effect of free alkali on the skin of the users. The presence of free fatty acid also affects the size of the bubbles in the foam formed by the bar of soap to impart a richer and creamier foam perception. Prior to the present invention, however, the incorporation of free fatty acids as a solid in the bars of soap was not possible. Solid forms of free fatty acids, such as stearic acid, ß when mixed with a soap in solid form, result in ^ a. formation of particulates or grains that can not be completely eliminated during the refining step, which includes the passage of the material through a sequencing and screens of various mesh sizes. The free fatty acids melted, which are solid at room temperature, on the other hand, crystallize when they are added to the solid soap in the mixer also resulting in the formation of grains in a finished bar of soap. The presence of an alkyl polyglucoside in a soap produces a bar that shows increased instant foaming and a richer and creamier foam.

BRIEF COMPENDIUM OF THE INVENTION: The present invention relates to a process for making a superfat personal cleaning rod having improved tactile and foaming properties, which involves the steps of: (a) providing a superfatting agent in solid form consisting of: i) a fatty component selected from the group consisting of free fatty acids of C6-C22 fatty alcohols of C6-C22 / Y mixtures thereof; and (ii) a nonionic sugar surfactant selected from the group consisting of an alkyl polyglucoside of the formula I: R ?O (Z) to I wherein Ri is a monovalent organic radical having from about 6 to about 30 carbon atoms. carbon; Z .- = a saccharide residue having 5 or 6 carbene atoms; and a is a number having a value from 1 nasr ^ approximately 6, a polyhydroxy fatty acid amide c, and mixtures thereof; (b) providing a soapy mixture of coconut / neutralized fatty acid, in solid form; (c) mixing components (a) and (b), followed by refining and extruded to form a bulk of supergrass soap bar; and (d) die-cutting of super-fat soap bar bulk bars. The process according to the invention produces a personal cleansing bar that is not very gentle on the skin, easily foams, prevents the formation of cream, is biodegradable and shows increased rapid foam formation, and a richer and creamier foam.
