Mild detergent compositions which exhibit good cleaning performance comprise detergent surfactants and small amounts of protease. A preferred embodiment additionally contains suds boosters and divalent ions.

Light duty liquid or gel dishwashing detergent compositions containing

Disclosed is a detergent composition comprising at least about 1% by weight, preferably at least about 3%, of a polyhydroxy fatty acid amide surfactant of the formula: ##STR1## wherein R.sup.1 is H, C.sub.1 -C.sub.4 hydrocarbyl, 2-hydroxy ethyl, or 2-hydroxy propyl, R.sup.2 is C.sub.7 -C.sub.31 hydrocarbyl, and Z is polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain, or alkoxylated derivatives thereof; and at least about 1%, by weight, preferably at least about 3%, of an alkyl ester sulfonate surfactant of the formula: ##STR2## wherein R.sup.3 is C.sub.8 -C.sub.20 hydrocarbyl, R.sup.4 is C.sub.1 -C.sub.6 hydrocathyl, and M is a soluble salt-forming cation.

Detergent composition containing polyhydroxy fatty acid amide and alkyl

Polyhydroxy amines reacted with fatty acid esters yield polyhydroxy fatty acid amide surfactants, such as the C.sub.11 -C.sub.17 fatty N-methyl glucamides, which may be contaminated with secondary amines. Such amines are acylated by a reaction with acetic anhydride. The resulting 'clean' polyhydroxy fatty acid amide surfactants are preferred for use in the presence of oxidants, especially in the formulation of modern, colorless liquid detergents.

Process for reducing the levels of unreacted amino polyol contaminants

The synthesis of polyhydroxy fatty acid amide surfactants exemplified by the compound C.sub.11 H.sub.23 C(O)N(CH.sub.3)CH.sub.2 [CHOH].sub.4 CH.sub.2 OH by reacting a fatty acid ester with an N-alkyl sugar amine can result in contamination of the product surfactant by residual sources of fatty acids. These residual fatty acids may be unacceptable in high sudsing detergent compositions, such as dishwashing liquids, especially with Ca or Mg cations. The process of this invention reacts such contaminants with alkyl amines or, especially, ethanolamine, to convert them into fatty alkyl- or alkanolamides, which are quite acceptable in fully-formulated detergent compositions for home or industrial use.

Process for reducing the levels of fatty acid contaminants in

High sudsing liquid detergent compositions contain anionic surfactant, polymeric surfactant which contains either linkages and a betaine surfactant for improved grease handling.

Comprising anionic surfactant polymeric nonionic surfactant and betaine

Disclosed are conditioning agents and compositions containing such conditioning agents wherein the conditioning agents contain an amine-anionic compound ion-pair complex. These conditioning agents can provide excellent fabric care benefits when applied as part of or in the presence of detergent compositions without significantly impairing cleaning performance. The conditioning agents contain particles which consist essentially of the ion-pair complex and which have an average particle diameter of from about 40 to about 300 microns.

Ion-pair complex conditioning agent with benzene sulfonate/alkyl benzene

Disclosed are conditioning agents and compositions containing such conditioning agents wherein the conditioning agents contain an amine-anionic compound ion-pair complex. These conditioning agents can provide excellent fabric care benefits when applied as part of or in the presence of detergent compositions without significantly impairing cleaning performance. The conditioning agents contain particles which consist essentially of the ion-pair complex and which have an average particle diameter of from about 10 to about 300 microns.

Ion-pair complex conditioning agent and compositions containing same

Disclosed are alkyl amine-anionic surfactant ion-pair/wax composites useful as fiber- and fabric-conditioning agents. Also disclosed are compositions containing these conditioning agents such as fabric detergent compositions, shampoos, hair conditioners and dryer- and washer-added fabric conditioners.

An agglomerated light-duty detergent granule composition containing an alkylpolysaccharide surfactant, an alkylbenzene sulfonate cosurfactant, an alkylpolyethoxylate sulfate cosurfactant and a water soluble inorganic salt.

Foaming surfactant compositions

A process for removing colored materials from alkylpolysaccharides by extracting the colored materials with polar solvents under essentially anhydrous conditions.

Polar solvent extraction of colored materials from alkylsaccharides

Long chain fatty alcohols can be removed from alkylpolysaccharide products in thin film evaporators to achieve fatty alcohol levels of less than about 2% without excessive discoloration of the alkylpolysaccharide.
