Abstract: A process for preparing homogeneous and stable heavy-duty liquid detergent compositions which comprises forming a blend of a solution of a builder salt and an emulsifying agent at an elevated temperature above about 60.degree. C. and cooling said blend to a lower temperature below about 45.degree. C., the amount of said builder salt dissolved in said solution at the elevated temperature being greater than the solubility of said salt in water at the lower temperature, the nature and amount of the emulsifying agent being such as to maintain the builder salt in stable dispersion in said blend at the lower temperature. The finished composition contains a water-soluble detergent surface active agent.

Abstract: Novel pyridazine-2-oxide derivatives inclusive of 3-mercaptopyridazine-2-oxides, disulfides thereof, metal salts thereof, and 3-(2-oxopyridazinyl)isothiouronium compounds having particular utility as antimicrobial agents per se and in skin cleansing detergent compositions, shampoos, hair dressing and the like.

Abstract: An improved article for conditioning fabrics includes at least one fabric conditioning compound, such as a softening agent, and a reinforcing, strengthening or extending material. The fabric conditioning compound and the article comprising it are usually of a waxy nature and are abradable or otherwise transferable to damp, warm fabrics by repeated contacts therewith experienced during tumbling effected in a drying zone, as of an automatic laundry dryer, through which hot drying air normally circulates. When such a softening article is rubbed against fabrics with which it comes in contact in the heat of the drying zone, softener is rubbed off onto the fabrics to be conditioned, after which the fabrics and laundry containing them are dried. The reinforcing or strengthening material is also dried at that time and is either removed from the fabrics by exiting drying air or is desirably held onto the fabrics that were treated, in conjunction with the softening agent.

Abstract: Detergent compositions using only alkali metal citrate and carbonate builder salts are disclosed. The detergent compositions disclosed have a lower alkalinity than phosphate-free detergents employing high concentrations of silicates.

Abstract: A non-staining aerosol antiperspirant comprising a suspension of an aluminum antiperspirant powder in an anhydrous system containing as the stain preventative, an effective amount of an electrolyte selected from the class consisting of alkali metal borates, polyphosphates, metaphosphates, citrates, silicates and tri-sodium nitrilotriacetate.

Abstract: An improved aerosol spray starch formulation is prepared by combining a starch component, a polyhydric material, a nonionic surfactant and a mixture of boric acid and borax in an aqueous medium together with a normally gaseous liquefied propellant. The starch formulation provides after pressing an excellent starching effect, that is, stiffness without roughness, without flaking or aerosol clogging.

Abstract: An article for conditioning fibrous materials includes a dispensing container of liquid fabric conditioning composition which has an opening in the wall thereof through which the conditioning composition is gradually dispensed into contact with fibrous materials to be conditioned. The conditioning composition is usually an aqueous solution of a surface active synthetic organic anionic, nonionic or cationic fabric conditioning agent, which is a softening agent that usually also makes the treated fabrics non-static. The container of conditioning composition usually includes a plurality of small dispensing openings therein and the viscosity of the solution of conditioning agent may be such that dispensing is preventable until the container comes into contact with materials to be treated or is subjected to shocks, as in tumbling of the container in contact with laundry being dried in an automatic laundry dryer.

Abstract: Wax polishing compositions in the form of a double emulsion wherein the continuous phase comprises organic solvent, organopolysiloxane and water-in-oil emulsifier and the discontinuous phase comprises aqueous particles having dispersed particles of wax therein. Compositions are prepared by adding at room temperature an aqueous media containing emulsified wax to a solvent solution containing organopolysiloxane and water-in-oil emulsifier, also at room temperature.
