The invention provides bar compositions with high level of sugar or sugars (greater than about 25% by wt.) and which can be extruded.

Extrudable soap bars comprising high levels of sugars

The invention provides process for making bar compositions with high level of sugar or sugars (greater than about 25% by wt.) and which can be extruded.

Soap bars comprising high levels of sugars made by extrusion route

The invention relates to perfume-containing bar compositions in which the effect of said perfume(s) (e.g., longevity) is enhanced relative to comparative bars in that perfume-containing bar of the invention, comprise less than about 35% soluble surfactant. The invention further comprises a process for enhancing deposition/longevity of perfume, for example, by controlling the level of soluble active relative to insoluble active and/or by increasing levels of perfume.

Compositions and process for preparing cleansing bars comprising low levels of soluble surfactant for enhanced fragrance deposition/longevity

The invention relates to soap/free fatty acid bars in which high amounts of free fatty acid (i.e., greater than 35%, preferably greater than 40% and ratio of FFA to soap greater than 1:1) and low levels of synthetic may be used. In the bar, the free fatty acid is believed to form a complex which is believed to act as a structurant, thereby allowing less use of synthetic surfactant. The bar should require less synthetic surfactant. Total amount of unsaturated material in soap and fatty acid should be no higher than 15% In a second embodiment of the invention, the bar may be made by a neutralization process whereby fatty acid is combined with caustic (e.g., lower than 50% caustic) to form soap and free fatty acid in defined amounts or proportions.

Bar with good user properties comprising acid-soap complex as structurant and low levels of synthetic

The invention relates to bar compositions which are structured in such manner (i.e., through specific ternary system) that bars can extrude well and have good properties (e.g., lather), even at low synthetic surfactant level.

Fatty acid soap/fatty acid bars which process and have good lather

The invention relates to compositions comprising soap which, when used with at least 3% monoglyceride and or free fatty acid, allows incorporation of desirable &agr;-hydroxy while retaining good ploddability properties. In another embodiment, the invention relates to process for making such bars.

Processable soap based bars comprising soaps of &agr; hydroxy acid and minimum amount of free fatty acid and/or monoglyceride

The invention discloses bars and process for making bars comprising synthetic anionic, fatty acid soap and hydroxy acid salt wherein bar can be extruded at minimum rates and wherein the bar and process are defined by specified ratio of hydroxy acid salt to calcite filler.

Predominantly synthetic bar comprising hydroxy acid salt and specific types and amounts of filler

The invention discloses bars comprising fatty acid soaps, free fatty acid, polyalkylene glycol and specific salts of protic acid (i.e., having pKa1 less than 6, preferably less than 5.5). Using specific equivalent molar ratios of free fatty acid to protic acid salt and specific wt. ratio of free fatty acid to PAG and salt of protic acid, applicants obtain bars having sensory feel of soap and which improve skin condition is measured in Controlled Application Wash Test.

Bar comprising soap, fatty acid, polyalkylene glycol and protic acid salts in critical ratios and providing enhanced skin care benefits

The invention discloses process for making bars comprising fatty acid soaps, free fatty acid, polyalkylene glycol and specific salts of protic acid (i.e., having pKa1 less than 6, preferably less than 5.5). Using specific equivalent molar ratios of fatty acid to protic acid salt and specific wt. ratio of PAG and salt of protic acid to free fatty acid, applicants obtain bars having sensory feel of soap and which improve skin condition in Controlled Application Wash Tests.

Process of making soap bar with enhanced skin benefits comprising adding salts of specific protic acid

An enzymatic bleach composition is provided comprising an enzymatic hydrogen peroxide-generating system and a bleach catalyst which is a coordination complex comprising manganese (Mn) and/or iron (Fe) ions, and preferably comprising a ligand L which is a macrocyclic organic compound of formula (I): ##STR1## wherein t is an integer form 2 to 3; s is an integer from 3 to 4, u is zero or one; each R.sup.1, R.sup.2 and R.sup.3 are independently selected from H, alkyl, aryl, substituted alkyl, and substituted aryl.

Enzymatic bleach composition

Sunscreen agents

A sunscreen composition for application to human skin comprises an ultraviolet absorber which is introduced as an anion into a layered double hydroxide of the general formula

A process is reported for preparation of quaternary ammonium type carbonate esters which are useful as bleach precursors in detergent compositions. The process involves transesterification of low molecular weight carbonates, e.g. diphenyl carbonate, with amino functionalized alcohols, e.g. dialkylaminoalkanol. Preferably the reaction involves transesterification of diphenylcarbonate with the hydroxyl compound followed by removal of phenol. Subsequent thereto the transesterified ester is quaternized with an alkylating agent. Optionally there may be a sulfonation of phenol ester subsequent to the quaternization reaction.

Transesterification route to quaternary ammonium substituted carbonate

A bleaching composition in concentrated form is provided that includes a peroxygen compound and an organic bleach precursor. The precursor is selected from esters and carbonates having a leaving group whose conjugate acid has a pKa of greater than 13. Particularly preferred are quaternary ammonium functionalized compounds. Absent preconcentration of the components, poor bleaching would result. Concentrated compositions may be achieved through use of encapsulation or by way of a sachet.

Ester perhydrolysis by preconcentration of ingredients

A particulate additive is reported which is an intimately blended mixture of a precursor, a stabilizing agent and a dispersing agent. The precursor is a quaternized ammonium or phosphonium substituted carbonic acid ester. A C.sub.4 or higher organic acid having at least one carboxylic group, such a lauric acid, or a solid inorganic acid, such as potassium bisulfate, is required as the stabilizing agent. Various alkoxylated fatty alcohols, fatty acids or alkylated phenols are utilized as the dispersing agent. These particulate additives are employed as adjuncts in bleaching-detergent compositions.
