Abstract:
The present invention relates to an aerosol hairspray product. The product comprises: a pressurisable container comprising a container wall which encloses a reservoir for storing a hairstyling formulation and a liquefied gas propellant; and a spraying device attached to the container for dispensing the hairstyling formulation from the reservoir of the container. The spraying device comprises a valve and a nozzle and the valve comprises a valve body, a stem and a spring means. The valve body houses an insert and the insert comprises an insert orifice and at least two channels. The channels are tangentially disposed about the insert orifice. Also the valve body comprises at least two vapour taps. Furthermore the insert orifice is capable of being in liquid communication with the hairstyling formulation in the reservoir.

Claim (Index 1):
A method of styling hair comprising:\n a. providing an aerosol hairspray product comprising a pressurisable container comprising:\n i. a container wall which encloses a reservoir for storing a liquefied gas propellant and a hairstyling formulation; \n ii. a spraying device attached to the container for dispensing the hairstyling formulation from the reservoir of the container, wherein the spraying device comprises a valve and a nozzle;\n wherein the liquefied gas propellant wherein the propellant comprises from about 35% to about 50% dimethylether, by total weight of the hairstyling formulation and propellant; \n wherein the hairstyling formulation comprises:\n from about 41% to about 60% water, by total weight of the hairstyling formulation and propellant; \n from about 5.0% to about 15% hairstyling polymer by total weight of the hairstyling formulation and propellant, wherein the hairstyling polymer is water-soluble; \n wherein the hairstyling formulation is free of ethanol, isopropanol, and propanol; \n wherein the hairstyling formulation without propellant has a viscosity of from about 0.5 cSt to about 6 cSt, wherein the viscosity is measured at 20\u00b0 C.+/\u22120.1\u00b0 C.; \n \n \n b. causing the product to spray at a delivery rate, wherein the delivery rate is from about 0.25 g/sec to about 0.45 g/sec;\n wherein an ejected composition is sprayed and comprises particles having an average particle size distribution (Dv50) from about 40 microns to about 100 microns.
