Claim 3

A detergent composition according to claim 1 wherein the synthetic organic detergent contains a hydrocarbon sulfonate having 8 to 26 carbon atoms and the content of alkaline protease is about one Anson unit thereof for each 200 to 400 grams of detergent composition.

Claim 4

A composition according to claim 2 in which the hydrocarbon sulfonate is sodium linear alkyl benzene sulfonate, having 10 to 16 carbon atoms in the alkyl group thereof and in which there is present a water soluble builder salt, with the proportion thereof being 50 to 1,000 parts by weight per 100 parts by weight of synthetic organic detergent and the content of alkaline protease is about 3/8 Anson unit per 100 grams of detergent composition.

Claim 5

A composition according to claim 3 wherein the synthetic organic detergent is a mixture of about 10 parts of sodium linear tridecylbenzene sulfonate, about 2 parts of the ethoxylation product of 11 mols of ethylene oxide and a primary alkanol of 14 to 15 carbon atoms and about 2 parts of sodium soap of higher fatty acids and the builder salt is pentasodium tripolyphosphate.

Claim 6

A built synthetic organic detergent composition for use in washing fabrics which consists essentially of a mixture of an alkaline builder salt and a minor proportion of a mixture of a surface active synthetic organic detergents selected from the group consisting of anionic, nonionic and amphoteric detergents, and an enzyme powder, which enzyme powder consists essentially of a mixture of bacterial alpha-amylase and alkaline protease with the proportion thereof being about 90,000 Novo alpha-amylase units of bacterial alpha-amylase to about 3/8 Anson unit of alkaline protease, the builder salt being present in an amount corresponding to about 50 to 1,000 parts thereof by weight per 100 parts by weight of said surface active synthetic organic detergent and said alkaline protease being present in an amount to provide one Anson unit thereof for each 100 to 500 grams of detergent composition.

Claim 7

A built synthetic organic detergent composition for use in washing fabrics which consists essentially of a mixture of an alkaline builder salt and a minor proportion of a mixture of a surface active synthetic organic detergents selected from the group consisting of anionic, nonionic and amphoteric detergents, and an enzyme powder, which enzyme powder consists essentially of a mixture of bacterial alpha-amylase and alkaline protease with the proportion thereof being about 90,000 Novo alpha-amylase units of bacterial alpha-amylase to about 3/8 Anson unit of alkaline protease, the builder salt being present in an amount corresponding to about 50 to 1,000 parts thereof by weight per 100 parts by weight of said surface active synthetic organic detergent and said alkaline protease being present in an amount to provide one Anson unit thereof for each 100 to 500 grams of detergent composition.

Claim 8

A composition according to claim 5 which has a pH, measured in 0.15% aqueous solution, of 9 to 10.5.

Claim 9

In the washing of fabrics in wash water containing a surface active synthetic organic detergent selected from the group consisting of anionic, nonionic and amphoteric detergents, and water soluble builder salt, said builder salt being present in an amount of about 50 to 1,000 parts by weight per 100 parts by weight of said synthetic organic detergent, the improvement which comprises including in the wash water a mixture of enzymes, which mixture consists essentially of bacterial alpha-amylase and alkaline protease with the proportion thereof being about 90,000 Novo alpha-amylase units of the bacterial alpha-amylase to about 3/8 Anson unit of alkaline protease and with the amounts of such enzymes being such as to provide one Anson unit of the alkaline protease for each 100 to 500 grams of detergent composition.

Claim 10

In the washing of fabrics in wash water containing a surface active synthetic organic detergent selected from the group consisting of anionic, nonionic and amphoteric detergents, and water soluble builder salt, said builder salt being present in an amount of about 50 to 1,000 parts by weight per 100 parts by weight of said synthetic organic detergent, the improvement which comprises including in the wash water a mixture of enzymes, which mixture consists essentially of bacterial alpha-amylase and alkaline protease with the proportion thereof being about 90,000 Novo alpha-amylase units of the bacterial alpha-amylase to about 3/8 Anson unit of alkaline protease and with the amounts of such enzymes being such as to provide one Anson unit of the alkaline protease for each 100 to 500 grams of detergent composition.
