Abstract: The present invention provides a method for souring, using an scouring agent composition which has low-viscosity although being highly concentrated, which has excellent scouring property under highly alkaline conditions, and which has excellent biodegradability. That is, the present invention provides a method for scouring fiber, which comprises the step of treating the fiber with a scouring agent comprising (A) a nonionic surfactant having the formula (I):R.sub.1 --O--(EO).sub.l (PO).sub.m (EO).sub.n H (I)in which R.sub.1 is an alkyl or an alkenyl, being straight or branched, having 8 to 22 carbon atoms, EO is an oxyethylene unit, PO is an oxypropylene unit, l and n are an average mole number of added oxyethylene units, m is an average mole number of added oxypropylene units, l is a number of 1 to 12, m is a number of 1 to 4 and n is a number of 1 to 12, provided that (EO).sub.l, (PO).sub.m and (EO).sub.n are blocks connected in this order.
Abstract: A process for making a granular suds suppressing component comprises the steps of intimately mixing a liquid or molten suds suppressing component with an emulsifier to form a premix and granulating the premix with a powder. The powder comprises aluminosilicate. The emulsifier is an anionic surfactant. The premix comprises a structuring agent selected from the group consisting of phosphonic and diphosphonic acid, carboxylic and polycarboxylic acid, succinic and disuccinic acid, and salts, and mixtures thereof.

Abstract: Heavy duty liquid or granular detergent compositions containing emulsions of silicone and selected emulsifying surfactants are disclosed. The silicone emulsions preferably have an average particle size of from about 20 to about 300 microns and provide exceptional cleaning and softening benefits.
Abstract: Personal cleansing bar compositions which contain a fragrance-releasing complex and a bar carrier. The fragrance-releasing complex contains a hydrophilic inorganic porous fragrance carrier and a fragrance impregnated within the fragrance carrier. The ratio of the fragrance:fragrance carrier ranges from about 5:1 to about 1:10.
