The present invention relates to a liquid detergent composition including (a) an anionic surfactant containing a hydrocarbon group having 10 to 18 carbon atoms, (b) an amine oxide surfactant containing a hydrocarbon group having 10 to 18 carbon atoms, (c) 2-ethylhexyl monoglyceryl ether, a compound represented by the formula (5) or a compound represented by the formula (6) and (d) water in each specified ratio:R&#x2014;(OR)&#x2014;OH&#x2003;&#x2003;(5)R&#x2014;(OR)G.&#x2003;&#x2003;(6)

Liquid detergent composition comprising an anionic surfactant, amine oxide, and alkyl glyceryl ether

The softener composition of the present invention comprises a compound having one or more Chydrocarbon groups and two or more groups selected from an amino group and a quaternary ammonium group in the molecule (component (a)), an anionic surfactant having a Chydrocarbon group (component (b)) and a nonionic surfactant (component (c)), wherein the molar ratio of the component (a) to the component (b) is from 90/10 to 50/50. This softener composition can endow cotton and cotton clothes in particular with a preferred softness, elasticity (fluffy feeling) and feeling of dryness with small oiliness.

Softener composition

The present invention provides a laundry detergent sheet with significant improvements in solubility. That is, the invention provides a sheet of laundry detergent comprising a layer containing a detergent composition and a water-soluble substrate provided on both sides of the layer, wherein said layer comprises a water-soluble or disintegrating-in-water particle group, having an average particle diameter of 60 to 2000 &mgr;m, consisting of a particle group. The water-soluble or disintegrating-in-water particle group means less than 0.025 g of residue on a screen after 0.5 g of the particle group is introduced into 1 L water at 10&deg; C., stirred at a revolution rate of 800 rpm for 10 minutes, and sifted through a screen of 200 mesh size.

Article for use in washing in sheet form

An economical sheetlike article for laundry whose flexibility is excellent, of which sprinkling and loss of the content are small and wherein a water-soluble substrate having a low basis weight is used. Thus, the present invention provides a sheetlike article for laundry in which a layer containing at least one composition selected from the group consisting of a detergent composition, a fiber softener composition and a bleaching agent composition, is connected with a water-soluble substrate on the both sides of the said layer, and of which the flexibility parameter calculated by a specific method is from 3 to 6.

Sheet-form laundering article

The softener composition of the present invention comprises a compound having one or more C hydrocarbon groups and two or more groups selected from an amino group and a quaternary ammonium group in the molecule (component (a)), an anionic surfactant having a C hydrocarbon group (component (b)) and a nonionic surfactant (component (c)), wherein the molar ratio of the component (a) to the component (b) is from 90/10 to 50/50. This softener composition can endow cotton and cotton clothes in particular with a preferred softness, elasticity (fluffy feeling) and feeling of dryness with small oiliness.

To provide a sheetlike article for laundry which is freed from the scattering or leak of the contents, facilitates arbitrary dispensing and exhibits excellent detergency even when used alone, sheetlike water-soluble substrates are arranged on both surfaces of a thin layer made of a doughy non-phosphate detergent composition which contains nonionic surfactant(s), alkaline agent(s) and sequestering agent(s) and has a penetration hardness at 25&deg; C. of from 0.1 to 10 kg/cm .

Sheetlike article for washing

A high-density powdered detergent composition which has a bulk density of 0.6 to 1.2 g/ml and which comprises 0.5 to 30% by weight of (a) a glycine-N,N-diacetic acid derivative, 5 to 45% by weight of (b) a nonionic surfactant having an HLB value of 10.5 to 15.0, 0.5 to 18% by weight of (c) an anionic surfactant and 1 to 30% by weight of (d) an aluminosilicate, each percentage being based on the total weight of the composition, and the weight ratio of the component (b) to the component (c) lying between 90:1 and 60:40. This composition contains both a glycine-N,N-diacetic acid derivative which is a builder excellent in biodegradability and sequestering power and an inorganic builder such as zeolite or crystalline silicate, and exhibits high detergency.

High-density powdered detergent composition

A high-density powdered detergent composition which has a bulk density of 0.6 to 1.2 g/ml and which comprises 0.5 to 30% by weight of (a) a glycine-N,N-diacetic acid derivative, 20 to 50% by weight of (b) an anionic surfactant, 0.5 to 5% by weight of (c) an ether-type nonionic surfactant having an HLB value of 10.5 to 15.0 and 1 to 30% by weight of (d) an aluminosilcate, each percentage being based on the total weight of the composition, and the component (c) being contained in an amount of 0.5 to 10.0 parts by weight per 100 parts by weight of the component (b). This composition contains both a glycine-N,N-diacetic acid derivative which is a builder excellent in biodegradability and sequestering power and an inorganic builder such as zeolite or crystalline silicate, and exhibits high detergency.

An electrically conductive paste composition comprises an electric conductive powder, an organic binder comprising (A) a polyhydroxystyrene derivative and (B) a thermosetting resin at a weight ratio of (A) to (B) in the range between 5/95 and 95/5 and a solvent. The paste is used for an electric circuit printed on a substrate and improved in view of migration resistance, flexibility and reliability.
