Abstract: The invention provides a shaped solid, three-dimensional skeleton structure comprising: a relatively rigid, interlocking mesh of neutralized crystalline carboxylic acid. In another respect, the present invention provides an improved cleansing bar which is comprised of the rigid, interlocking mesh of neutralized carboxylic acid, preferably sodium soap fibers. Such preferred cleansing bars can be formulated to have essentially no bar smear. Some cleansing bars comprise surprisingly large amounts of water and other liquids while maintaining their rigidity and excellent smear properties; even when allowed to soak overnight in water.

Abstract: The present invention relates to an improved freezer bar soap comprising selected saturated C.sub.14 -C.sub.18 fatty acid soaps and lathering soap selected from lauric, oleic, and other minor selected more soluble soaps. The bars of this invention have improved mildness while maintaining acceptable lathering/sudsing characteristics.

Abstract: The present invention relates to an improved freezer bar soap comprising selected saturated C.sub.14 -C.sub.18 fatty acid soaps and lathering synthetic surfactant. The bars of this invention have reduced bathtub ring, as well as improved mildness while maintaining acceptable lathering/sudsing characteristics.

Abstract: The invention provides a firm, ultra mild, neutral pH cleansing bar comprising: from about 5% to about 50% of monocarboxylic acid; wherein from about 20% to about 65% by weight of said monocarboxylic acid is neutralized; from about 20% to about 65% of an anionic and/or nonionic bar firmness aid, and from about 15% to about 55% water by weight of said bar;wherein said free monocarboxylic acid is from about 35% to about 80% by weight of said mixture of free and neutralized monocarboxylic acid;wherein said neutral pH is from about 6.3 to about 8.0;wherein the said neutralized monocarboxylic acid has a cation selected from the group consisting of sodium, magnesium, calcium, aluminum, and mixtures thereof; andwherein said bar comprises a rigid crystalline phase skeleton structure comprising an interlocking, open three-dimensional mesh of elongated crystals consisting essentially of said monocarboxylic acid.

Abstract: An isotropic liquid cleansing composition which is cosmetically attractive, stable and which also has excellent lather performance properties. The composition contains a water-soluble triethanolamine fatty acid soap, an electrolyte thickener selected from citrates, formates and tetraacetate, a synthetic surfactant, and water as essential components and has a neat viscosity (100%) of about 2,000 to 12,000 cps.

Abstract: The invention provides a firm, low smear, ultra mild, weakly acidic skin pH cleansing bar comprising by weight of said bar: from about 5% to about 50% of essentially free carboxylic acid, preferably myristic acid, behenic acid, or 12-hydroxy stearic acid; from about 15% to about 65% of a water-soluble organic anionic and/or nonionic bar firmness acid, preferably sodium cocoyl isethionate or sodium lauroyl isethionate; and from about 15% to about 55% water. The skin pH bar can contain little or no soap, yet has a shallow penetration value of from zero up to 12 mm. The bar is a framed bar.

Abstract: The invention provides a firm, ultra mild, neutral pH freezer bar comprising: from about 10% to about 50% of monocarboxylic acid; wherein from about 20% to about 65% by weight of said monocarboxylic acid is neutralized; from about 20% to about 65% of an anionic and/or nonionic bar firmness aid, and from about 15% to about 40% water by weight of said bar;wherein said neutral pH is from about 6.3 to about 8.0;wherein the neutral pH freezer bar is made by the following steps:I. mixing a molten (170.degree.-205.degree. F.; 76.degree.-96.degree. C.) mixture comprising said carboxylic acid; water; and bar firmness aid; neutralizing said 20% to about 65% of said carboxylic acid, preferably with sodium hydroxide;II. cooling said mixture to a semi-solid in a scraped wall heat exchanger freezer;III. extruding said semi-solid as a soft plug; and further cooling and crystallizing said soft plug until firm to provide said neutral pH personal cleansing freezer bar.

Abstract: The invention provides a firm, low smear, ultra mild, weakly acidic skin pH (4.8-6.0) personal cleansing freezer bar comprising by weight of said bar: a sum total of from about 10% to about 50% of essentially free carboxylic acid, preferably myristic acid, behenic acid, or 12-hydroxy stearic acid; from about 15% to about 65% of a water-soluble organic anionic and/or nonionic bar firmness aid, preferably sodium cocoyl isethionate or sodium lauroyl isethionate; and from about 15% to about 40% water.The skin pH freezer bar is made by the following process steps:I. mixing a molten (170.degree.-205.degree. F.; 76.degree.-96.degree. C.) mixture comprising said essentially free carboxylic acid; water; and bar firmness aid;II. cooling said mixture to a semi-solid in a scraped wall heat exchanger freezer at a cooled temperature of 110.degree.-195.degree.

Abstract: Aerated soap bar compositions which contain a limited amount of free fatty acid and salt have improved processing and physical characteristics if the fatty acid soap comprises only a limited amount of trans fatty acids. Superior wet crack and bar feel grades are found, as opposed to similar bars having higher trans fatty acid content. Higher amounts of fatty acid require less inorganic salt for proper viscosity of the crutcher mix.

Abstract: Aerated and/or freezer soap bar compositions which contain a substantial amount of sucrose have improved processability, improved physical and/or improved skin mildness characteristics.
