A detergent granule and tablets which comprises an anionic surfactant system which comprises an anionic sulphate surfactant and/or an anionic sulphonate surfactant and other detergent active ingredients, the granule comprising at least a first and a second particulate component and optionally a binding agent, characterised in that the ratio of anionic sulphate surfactant to anionic sulphonate surfactant in the particulate components and in the optional binding agent is less than 1:4 or more than 4:1, preferably even less than 1:5 or more than 5:1. The invention also relates to specific granules comprising restricted degree of mixing of anionic sulphonate surfactant and zeolite, anionic sulphate surfactant and carbonate salts and/or restricted degree of mixing of polymeric builder and anionic surfactant, in particular sulphate surfactants.

Detergent granules

The present invention relates to detergent compositions comprising anionic mid-branched surfactant compounds and additional anionic sulfate and sulfonate surfactants. The compositions are particularly useful as solid laundry detergent compositions.

Detergent composition comprising mid-chain branched surfactants

A detergent composition, having a selected surfactant system for improved performance, especially under high water hardness and low temperature wash water conditions is disclosed. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant in combination with a linear alkylbenzene sulfonate surfactant, and linear alkyl sulfate surfactant at optimally selected relative proportions. Additionally, the detergent composition contains up to about 5% of an alkyl ethoxylated sulfate surfactant and up to about 5% of a nonionic surfactant while unexpectedly having improved performance with such relatively low levels of a nonionic surfactant.

Detergent composition with a selected surfactant system containing a mid-chain branched surfactant

Granular detergent compositions are prepared by an agglomeration process and impregnated with a water-insoluble disintegrant to improve water solubility. Laundry detergent compositions are described.

Disintegrant-impregnated detergent agglomerates with improved solubility

Mid-chain branched surfactants derived from mid-chain branched primary alkyl hydrophobic groups and hydrophilic groups. The present invention also relates to mixtures of mid-chain branched surfactants useful in laundry and cleaning compositions, especially granular and liquid detergent compositions.

Mid-chain branched surfactants with cellulose derivatives

A detergent composition containing a mixture of linear alkybenzene sulfonate surfactant and mid-chain branched surfactant and an electrolyte is disclosed. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant and an electrolyte capable of increasing the ionic strength of the compositions resulting in improved performance, especially under low water temperature wash conditions. Typical electrolytes include sodium chloride, magnesium sulfate, calcium carbonate and the like.

Detergent composition containing mid-chain branched surfactants and an electrolyte for improved performance

Alkoxylated cationic surfactants, and mixtures thereof, are used in detergent compositions.
