A polymeric aerosol dispenser that is recyclable. The recyclable polymeric aerosol dispenser including all polymeric components. These components being selectively either fixedly joined or separably joined based on the material composition of the component. Further, components may be selected for their density and, thus, their ability to float or sink during the recycling process. The recyclable polymeric aerosol dispenser is designed to minimize its impact on the PET recycling stream and to align with industry recyclability guidelines.

The invention relates to a method for reducing water content of an epoxy or/and polyurethane paint dispersion to be prepared in a sealed and pressurized aerosol can which paint dispersion comprises, —free water of an amount W1, —organic solvent(s) of an amount W2,5-epoxy or/and polyurethane resin of an amount W3, —liquefied propellant of an amount W5, —ketone of an amount W6, —blocked hardener (hardener precursor) of the epoxy or/and polyurethane resin of an amount W4, wherein said blocked hardener compounds of said epoxy or/and 10 polyurethane resin is selected from the group comprising of an aldimine, an enamine, an imine, a Mannich base, a Schiff's base, an oxazolidine or a bisoxazol-idine, and mixtures thereof, —adjuvants, —water scavenger(s), —catalytic amount of a weak acid to shift equilibrium of reversible reaction (I) between the free water present in said dispersion and blocked hardener compounds of the epoxy or/and polyurethane resin back to formation of said initial epoxy or polyure-thane blocked hardener compounds and to prevent formation of the epoxy or/and polyurethane hardener amines: expoxy and/or polyurethane hardener+ketones catalyst expoxy and/or polyurethane+free water (amine) hardener precursor (1). The method comprises a step in which before providing organic solvent into the aerosol can its water content is reduced by admixing reactant with sulfonyl isocya-nate functionality as a water scavenger into said organic solvent.

The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

A hand held spray device is disclosed. The spray device includes a body with a reservoir, an actuator with an actuator exit orifice, a valve in fluid communication with the actuator exit orifice and the reservoir and a propellant and antiperspirant composition stored in the reservoir. The propellant has a concentration from about 30% to about 70% by weight of the total fill of materials stored within the reservoir and a boiling point at 1 atmosphere from about −10° C. to about 10° C. The antiperspirant composition includes a liquid carrier and an antiperspirant active.

The application describes a cosmetic agent for temporary deformation of keratinic fibers. The cosmetic agent includes, in a cosmetically acceptable carrier, a) at least one copolymer A formed from at least one monomer A1 selected from acrylic acid and/or methacrylic acid and at least one monomer A2 selected from acrylic acid esters and/or methacrylic acid esters, b) at least one cationic polymer B different from copolymer A selected from cationic guar derivatives, c) at least one polymer C different from copolymer A and polymer B, selected from cationic cellulose derivatives, and d) at least one propellant.

The present invention relates to an aerosol device comprising: —a container containing a cosmetic composition which comprises one or more powders in a content of less than 7% by weight relative to the total weight of the composition, and—a dispensing head comprising a body and an end part comprising at least two outlet orifices configured to allow spraying of the composition about a longitudinal axis of the end part in at least two different directions, the dispensing head comprising at least first and second chambers, through which the composition stream successively passes before it exits via the outlet orifices.

A pressurized container assembly includes a pressurized container, a valve, and a shearing chamber. A flowable product and propellant are also provided within the container. The propellant is substantially non-soluble in the flowable product. Methods of producing a foamed flowable product using shearing chambers are also disclosed.

The present invention relates to an aerosol product having reduced volatile organic compound (VOC) content. Environmental sustainability has become a matter of growing interest in aerosol applications. There remains a need for an aerosol product with reduced volatile organic compound while retaining the spray characteristics such as spray consistency throughout the use of the product. It is therefore an object of the present invention to provide an aerosol product with reduced volatile organic compound while retaining the spray consistency throughout the use of the product. It has been found that spray consistency can be achieved by mixing 5 to 15% of one or more liquefied gasses by weight of the base formulation with an insoluble compressed gas, in combination with a specific inert gas fill pressure in the container.

The present disclosure relates to, inter alia, a formulation in a package. The formulation comprises one or more active agents and is co-mingled with a whipping agent prior to being filled under pressure into the package. The whipping agent is added in sufficient amounts to be dispersed in the formulation. The pressurized package is under sufficient pressure suitable to maintain the whipping agent dispersed in the formulation; and the pressurized package is under sufficient pressure to expel the formulation as a whipped formulation upon application of external force on the formulation in the package.

A method of warming food dispensable from an aerosol dispenser. The aerosol dispenser is made from materials which can go into a single recycling stream having a single class of materials, as defined by the Society of the Plastics Industry, and particularly may exclusively comprise Class 1 materials suitable for eating in a microwave oven. Consumer products, such as food, contained in the aerosol dispenser may be heated in a microwave oven prior to dispensing. Upon dispensing, food retains residual heat, and is suitable for eating or further cooking. Other heated products in the aerosol dispenser may be comfortably applied to the skin, used as air freshener, used for cleaning, etc. The aerosol dispenser may have indicia indicating the aerosol dispenser is suitable for microwave heating. The aerosol dispenser can have indicia indicating the aerosol dispenser is suitable for heating in a microwave oven. The indicia may be thermochromic, indicating when a desired temperature has been reached. The aerosol dispenser can have a safety valve, to safely relieve product and/or propellant pressure upon overpressurization in a microwave oven. The safety valve may be single use or reusable.
