Abstract: A cotton swab is described whose stick is formed from an elongate stem with a conical member at each end flared outwardly and having a hollow center. The hollow flared conical members provide expanded swab ends rendering the tips softer and larger yet employing less cotton and paper in its manufacture. A die-cut paper used for forming the swab stick and a manufacturing process are also described.

Abstract: Certain cyclic aliphatic unsaturated compounds which sufficiently inhibit LRAT or ARAT catalyzed esterification of retinol into inactive retinyl esters, have the same effect on keratinocytes as retinoic acid. Thus, effects of the retinol or retinyl esters in combination with these cyclic compounds are analogous to treatment with retinoic acid.

Abstract: A cosmetic composition for forming a peelable skin mask is provided based on a combination of polyvinyl alcohol and a hydrophobically-modified acrylate or methacrylate polymer. Most effective is a combination of two weight grades of polyvinyl alcohol, a low weight grade having a number average molecular weight ranging from about 15,000 to about 27,000 and a high weight grade having a number average molecular weight ranging from about 44,000 to about 65,000. The hydrophobically-modified acrylate or methacrylate polymer preferably is a copolymer formed from a carboxylic monomer and a C.sub.8 -C.sub.30 acrylate ester.

Abstract: Oil-in-water emulsions containing an unstable retinoid (retinol or C.sub.2 -C.sub.3 ester thereof) in an oil phase. The retinoid is stabilized in the inventive emulsions, despite the presence of from about 50% to about 98% of an aqueous phase. The emulsions also preferably include a hydroxy acid.

Abstract: A dual compartment pump dispenser is provided which includes a first and second container with a pair of independent pump mechanisms each for emptying product through a respective dispensing nozzle. The dispensing nozzles have openings oriented in a direction at least 60.degree. apart from one another, preferably 180.degree. apart. Different compositions are intended to be stored in each container for sequential rather than simultaneous use. The containers are joined along a sinusoidal curvilinear surface having complementary mating elongated recesses and ridges. A collar and base cup fasten the containers together.

Abstract: A toothbrush is provided having a brushhead, neck and handle. The handle includes a flex zone flanked on one side by the neck on the other by a tail zone of the handle. The neck and tail zone are rigid in contrast to the bendable flex zone. Spring Rate for the neck and tail zone is each greater than that for the flex zone. A relatively hard, unitarily formed backbone traverses neck and handle. An elastomer forms portions of both the flex and tail zones. Elastomer is anchored through at least one channel traversing a beam of the backbone. Ends of the channel are radiused to eliminate structural weakness.

Abstract: A dispenser is provided that includes a container for storing a dispensable chemical product such as an underarm composition, an elevator mounted for axial movement within the container, a rotatable shaft attached to the elevator, a compartment within the container below the elevator and mechanisms for axially advancing and for reciprocating the elevator within the container. Each mechanism is actuated through a depressible button protruding from the housing. A flexible plastic band serving as a biasing spring is unitarily molded with the button as a plastic insert. The advancement mechanism includes a ratchet wheel with a plurality of teeth circumferentially surrounding the wheel and a pawl, attached to the plastic insert, for moving the teeth of the ratchet wheel. The reciprocating mechanism includes an angled ramp attached to an underside of the button.

Abstract: A hairspray composition is described that includes a nonionic polymer and an anionic polymer. The nonionic polymer is formed from monomers having at least one unneutralized carboxylic acid. The anionic polymer is identical to the nonionic one, except that all of the carboxylic acid groups are in salt form. Advantageously, the composition further includes an acrylic resin, most especially an amphoteric one. Best results are achieved when the acrylic resin is neutralized with a relatively small cation such as potassium and a second cation of a water soluble fatty amine. These compositions employ water as the carrier and dimethyl ether as propellant.
