Framed Neutral pH Cleansing Bar

Patent Number: 5262079

Type: Grant

Filed: March 20, 1992

Date of Patent: November 16, 1993

Assignee: The Procter & Gamble Company

Inventors: Mark L. Kacher, James E. Taneri, Daniel J. Quiram, Diane G. Schmidt, Marcus W. Evans

Abstract: This invention is made up of a firm, ultra mild, neutral pH cleansing bar. It is comprised of about 5 to 50% of monocarboxylic acid, wherein 20 to 65% of that weight is a neutralized form of monocarboxylic acid. With 20 to 65% of the bar being anionic and/or nonionic bar firmness aid, and about 15 to 55% is made up water. Wherein the free monocarboxylic acid is from about 35 to 80% by weight of a mixture of free and neutralized monocarboxylic acid. Neutral pH is from 6.3 to 8.0, wherein the said neutralized monocarboxylic acid has a cation selected from a group that is made up of sodium, magnesium, calcium, aluminum, and other mixtures. The bar is also comprised of a rigid crystalline phase skeleton structure comprising of an open yet interlocking, three-dimensional mesh of elongated crystals that are made from monocarboxylic acid.

 

Framed Skin pH Cleansing Bar

Patent Number: 5227086

Type: Grant

Filed: March 20, 1992

Date of Patent: July 13, 1993

Assignee: The Procter & Gamble Company

Inventors: Mark L. Kacher, James E. Taneri, Diane G. Schmidt, Teresa K. Wong

Abstract: This invention provides a firm, low smear, ultra mild, weakly acidic skin pH cleansing bar. The weight of the bar is made up of the following: 5 to 50% of essentially free carboxylic acid, myristic acid, behenic acid, and 12-hydroxy stearic acid. 15 to 65% of water-soluble organic anionic and/or nonionic bar firmness acid, that is made of either sodium cocoyl isethionate or sodium lauroyl isethionate, as well as 15 to 55% water. The pH of the skin bar may contain little to no soap, but still, has a penetration value of zero to 12mm. This cleansing bar is a framed bar.

 

Neutral pH Freezer Bar and Process

Patent Number: 5225098

Type: Grant

Filed: March 20, 1992

Date of Patent: July 6, 1993

Assignee: The Procter & Gamble Company

Inventors: Mark L. Kacher, James E. Taneri, Diane G. Schmidt, Marcus W. Evans, Constance S. Koczwara, Steven K. Hedges, Thomas F. Leslie

Abstract: The invention is a firm, ultra mild, neutral pH freezer bar. This bar is made up of 10 to 50% of monocarboxylic acid, 20 to 65% of this acid is neutralized. With 20 to 65% of anionic and/or nonionic firmness bar aid, and around 15 to 40% of the bar is made up of water. The neutral pH of the bar ranges between 6.3 to 8.0. The freezer bar is made by mixing a molten mixture made up of carboxylic acid, water, and bar firmness aid. While 20 to 65% of the carboxylic acid is neutralized using sodium hydroxide. Next, the mixture is left to cool down, in an exchanger freezer, to a semi-solid form. Once it is cooled down the soft mixture will continue to cool down forming into the neutral pH personal cleansing freezer bar.

 

Skin pH Freezer Bar and Process

Patent Number: 5225097

Type: Grant

Filed: March 20, 1992

Date of Patent: July 6, 1993

Assignee: The Procter & Gamble Company

Inventors: Mark L. Kacher, James E. Taneri, Diane G. Schmidt, Teresa K. Wong

Abstract: This invention creates a firm, low smeat, ultra mild, weakly acidic skin pH personal cleansing freezer bar. The bar is made up of 10 to 50% of essentially free carboxylic acid, which is mostly myristic acid, behenic acid or 12-hydroxy acid. With 15 to 65% of a water-soluble organic anionic and/or nonionic bar firmness aid that is usually sodium cocoyl isethionate or sodium lauroyl isethionate. The bar is also made of 15 to 40% water. The way that the bar is made is in the following process. First, a molten mixture is made up of essentially free carboxylic acid, water, and firmness aid. Once mixed it is set to cool down to a semi-solid mass before it is formed into a bar.

 

Detergent Composition Containing Coated Perfume Particles

Patent Number: 5188753

Type: Grant

Filed: June 21, 1991

Date of Patent: February 23, 1993

Assignee: The Procter & Gamble Company, Minnesota Mining & Manufacturing Company

Inventors: Diane G. Schmidt, Howard J. Buttery, Robert J. Norbury

Abstract: The perfume particles are made up of perfume dispersed within specific water-soluble polymeric carrier materials that are encapsulated within a protective shell, which is coated with a friable material. Once coated the particles allow for preservation as well as protection of perfumes. These are susceptible to lose while in storage or in harsh cleaning conditions. While in use, the surface coating is fractured and the perfume particles are effectively delivered to fabrics and other surfaces.

 

Coated Perfume Particles in Fabric Softener or Antistatic Agents

Patent Number: 5137646

Type: Grant

Filed: February 1, 1991

Date of Patent: August 11, 1992

Assignee: The Procter & Gamble Company, Minnesota Mining & Manufacturing Company

Inventors: Diane G. Schmidt, Howard J. Buttery, Robert J. Norbury

Abstract: Perfume particles are made up of perfume that is dispersed with specific water-insoluble polymeric carrier materials. It is then encapsulated in a protective shell that is coated with a friable material. Once coated, the particles allow for the preservation and protection of perfumes what could liable to a loss while in storage or in harsh cleaning conditions. When in use the surface coating pops and the perfume particles are dispersed into fabrics or other surfaces.
