A novel detergent composition containing an alkaline pullulanase is disclosed. The alkaline pullulanase has its optimum pH in an alkaline range and not deactivated by surfactants. Further it has strong resistance to almost all detergent components such as chelating agents, protease, etc. The the detergent composition of this invention has excellent detergency especially against starch soils.

Detergent composition containing alkaline pullylanase enzyme

A detergent composition containing an alkaline pullulanase, a surfactant, alkaline agents and/or inorganic electrolytes, divalent metal ion scavengers and bleaching agents is disclosed. The alkaline pullulanase has an optimum pH range of 8.5-10.0 on pullulan, an optimum temperature of about 50.degree. C. and is not deactivated by surfactants. Further, the pullulanase has a strong resistance to almost all detergent components such as chelating agents, proteases, etc. The pullulanase is isolated from Bacillus sp. KSM-AP 1378 deposited as FERM BP-3048. The composition specifically contains 0.1-10 wt. % alkaline pullulanase B, 0.5-60 wt. % surfactant, 0-90 wt. % alkaline agents and/or inorganic electrolytes, 0-50 wt. % divalent metal ion scavengers, and 0-85 wt. % bleaching agents.

Detergent composition containing an alkaline pullulanase from bacillus

A detergent composition comprising the components (a) and (b) specified below in a (b)/(a) weight ratio within the range of 1/300 to 1/2, and a detergent composition comprising the components (a) and (c) specified below in a (c)/(a) weight ratio within the range of 1/300 to 1/2:

Mild non-irritating alkyl glycoside based detergent compositions

A neutral liquid detergent composition is disclosed. The composition comprises: (a) 2-60% by weight of an alkyl glycoside; (b) 0.1-10% by weight of a nonionic surfactant having an HLB of less than 5; (c) 0.1-10% by weight of a nonionic surfactant having an HLB of not less than 5; and (d) 0.001-8% by weight of one or more water-soluble organic or inorganic salts. The composition exhibits reduced irritation and damage to the hair or the skin, and high foaming ability. It imparts a favorable feeling upon use. After washing, the detergent components can easily be rinsed off leaving the least amount of water on the washed tableware.

Neutral liquid detergent composition

A detergent composition comprises (a) an anionic or nonionic surfactant and (b) a dialkylamine oxide having the formula (I), a weight ratio of (a) to (b) ranging from 0.01 to 100, ##STR1## in which R1 and R2 each are an alkyl having 6 to 18 carbon atoms, an alkenyl having 6 to 18 carbon atoms, R3 is ethylene, isopropylene, n-propylene or a mixture thereof, R4 is an alkyl having 1 to 4 carbon atoms, a hydroxy alkyl having 1 to 4 carbon atoms, benzyl or hydrogen and n is a number of 1 to 20.

Detergent composition containing di-long chain alkyl amine oxides

A low irritant, mild detergent composition is disclosed. The detergent composition comprises, as essential components, (a) alkyl glycoside and (b) a specific type of dicarboxylic acid surface active agent at a specific ratio. The detergent composition is low irritant, has excellent foaming power and detergency, and yet is easily rinsed out and at the same time provides a pleasant feeling to the hands during use. It can be used as laundry detergents, dishwashing detergents, as well as detergents for use with household articles, and hair and body.

Mild detergent compositions containing alkylglycoside and dicarboxylic

Detergent compositions containing starch debranching enzymes

A low irritant, mild detergent composition is disclosed. The detergent composition comprises, as essential components, (a) alkyl glycoside, (b) a surface active agent containing sulfate and/or sulfonate group, (c) an amine oxide, and (d) an ethoxylated surface active agent at a specific ratio. The detergent composition is low irritant, has excellent foaming ability and detergency, and yet is easily rinsed out and at the same time provides a pleasant feeling to the hands during use. It can be used as laundry detergents, dishwashing detergents, as well as detergents for use with household products, and hair and body. Further, a detergent composition comprising (e) a terpene type hydrocarbon and (f) 3-isothiazolone or its derivative in addition to the above components (a)-(d) is more valuable in practical use owing to preventing solution color and odor from being deteriorated during storage for a prolonged period of time.

Mild alkyl glycoside-based detergent compositions, further comprising

A concentrated detergent composition comprising the following components (a)-(d) was disclosed,

Containing a succinic acid derivative

A liquid cleanser composition comprises 1 to 20 percent by weight of a surfactant and 3 to 70 percent by weight of a water-insoluble abrasive of the interpenetrated crystalline aluminosilicate zeolite crystals, composed of at least 30 crystals formed into an aggregate.

Liquid cleanser composition containing an abrasive crystalline

Disclosed is a liquid detergent composition which comprises the following three ingredients: (a) an alkanolamine salt of phosphoric ester represented by the formula (I) or (II) ##STR1## (b) an alkanolamine salt of a higher fatty acid, the alkanolamine having an alkyl group whose carbon atoms are 2 or 3 in number, and (c) an alkylamine oxide which has a hydrocarbon group having 10-14 carbon atoms.
