Abstract: A method of making a post foaming gel comprising the following steps: A gel base is cycled between first and second cylinders and a heat exchanger. A foaming agent is introduced to the cycled gel base through the heat exchanger while the gel base is being cycled.

Abstract: An apparatus for making post-foaming gels comprising, a piston chamber having an outer case defining a chamber, a piston being slidably received in the case and separating the chamber into a first compartment adjacent one end of the case for retaining a gel base, and a second compartment adjacent the other end of the case for retaining a compressed gas, with said piston having a hollow stem extending out of the other end of the case. The apparatus has a device for circulating the gel base through the stem and first compartment, and a device for introducing a foaming agent to the gel base while it is being circulated through the piston chamber.

Abstract: An apparatus for making a post-forming gel comprising, a first cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive a gel base and a second compartment, and a second cylinder having a chamber and a slidable piston separating the chamber into a first compartment to receive the gel base and a second compartment, with the first compartments of the first and second cylinder facing each other. The apparatus has a shaft connecting the pistons of the first and second cylinders, and a conduit connecting the first compartments of the first and second cylinders. The apparatus has a device for reciprocating the pistons in the first and second cylinders to cycle the gel base through the conduit between the first compartments of the first and second cylinders, and a device for introducing a foaming agent to the gel base while it is being cycled between the cylinders.

Abstract: An aerosol antiperspirant composition in the form of a substantially stable water-in-oil emulsion is disclosed which consists of 25% to 50% by weight of a liquefied, normally gaseous propellant and 50% to 75% of a base consisting essentially of, by weight, 4 to 20% of at least one water-soluble, astringent salt having antiperspirant efficacy; 0.5 to 5% of a water-in-oil emulsifier; 10% to 25% of a propellant-soluble emollient-stabilizer agent consisting of a water-insoluble, organic, liquid emollient and a water-insoluble organic liquid having a boiling point in the range of 35.degree. C. to 155.degree. C., the weight ratio of emollient to organic liquid being in the range of 0.8:1 to 3:1, and 55% to 78% of water. In preferred compositions, C.sub.3 -C.sub.4 hydrocarbon propellants are employed.

Abstract: A dispenser comprising a container having a neck provided with an outlet spout. A dip tube nozzle by use of a finger button is slidably mounted in the container and has a delivery opening alignable with the spout. Serrated teeth are formed on the container and dip tube and a piston is movably mounted on the dip tube for being depressed downwardly to force product up the dip tube. The piston is retained in the lowered position by the serrated teeth engaging a flexible disc while the dip tube is returned to a raised position by a suitable spring.

Abstract: A stable liquid toilet soap which includes a potassium soap which is a mixture of potassium soap of lauric acid and myristic acid and a viscosity controlling composition which is a mixture of coconut diethanolamide and sodium sulfate. The soap compositions have moderate viscosity, good odor, foam performance and feel.

Abstract: A liquid hard surface cleaning composition comprising, by weight, 1% to 20% of water-insoluble, particulate abrasive having a particle size in the range of 1 to 40 microns; 3% to 15% of a synthetic, organic, anionic detergent; 1% to 7.5% of an ethyleneoxylated alkanol nonionic detergent, the weight ratio of anionic detergent to nonionic detergent being from 1.75:1 to 3:1; 1% to 15% of a detergent builder salt, the weight ratio of builder salt to total detergent being in the range of 1:4 to 2:1; and an aqueous medium; the proportions of the components being so adjusted within the specified ranges that some of the detergent is present in liquid crystal form and the abrasive is maintained in stable suspension.

Abstract: A liquid hard surface cleaner is disclosed that is impalpable, self-opacifying, enjoys low temperature stability and has satisfactory viscosity and detergency, these being achieved by a particular combination of ingredients and proportions; namely, the composition comprising, by weight, a water-soluble, synthetic, anionic, sulphated or sulphonated detergent salt containing an alkyl radical of 8 to 22 carbon atoms in the molecule, a water-soluble alkylene oxylated nonionic detergent, a water-soluble detergent builder salt and the balance water, the weight ratio of anionic detergent to nonionic detergent being from 0:5 to 6:1 and the weight ratio of builder salt to total detergent being in the range of 1:5 to 5:1.

Abstract: A non-staining antiperspirant spray powder comprises an antiperspirant powder, such as aluminum chlorohydrate, an encapsulated surface active material, such as a liquid, nonionic surface active agent, with the encapsulating material about it being soluble or disruptable by aqueous media and insoluble in the propellant, and a propellant fluid under pressure. The composition is discharged from a container as a powder spray, preferably onto the axilla, by the opening of a discharge valve. The presence of the surface active agent diminishes staining of clothing contacted by the antiperspirant and its encapsulation in a soluble encapsulant allows the gradual release of surface active agent as the aluminum chlorohydrate is activated by the presence of perspiration, while also maintaining the dry character of the powder spray and preventing or diminishing mucous membrane irritation during spraying.

Abstract: A composition suitable for cleaning glass or glazed ceramic articles is described which comprises, by weight, 0.05% to 0.5% hydrofluroic acid or an acid salt thereof, a second water-soluble acid selected from the group consisting of 0.02% to 4% of acetic acid, hydroxy acetic acid, propionic acid and lactic acid and 0.05% to 0.8% of a non-oxidizing mineral acid other than hydrofluoric acid, 0.01 to 0.5% of a water-soluble anionic or nonionic organic detergent, 0% to 10% of a solvent selected from the group consisting of C.sub.1 -C.sub.4 alkyl ethers of ethylene glycol, C.sub.1 -C.sub.4 alcohols and C.sub.2 -C.sub.4 ketones and the balance water. Such compositions reduce water spots and stains and leave a shiny finish.
