Abstract: The present invention relates to an aerosol hairspray product. The product comprises: a pressurizable 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 vapor taps. Furthermore the insert orifice is capable of being in liquid communication with the hairstyling formulation in the reservoir.

Abstract: A hairstyling method comprising: providing an aerosol hairspray product comprising: a pressurisable container comprising a reservoir for storing a hairstyling formulation and a liquefied gas propellant, and a spraying device attached to the container; wherein the hairstyling formulation comprises: from about 30% to about 60% water; from about 4.0% to about 15% hairstyling polymer; less than about 2% alcohol; and wherein the hairstyling formulation without propellant has a kinematic viscosity of about 6 cSt or less; and causing the product to spray at a delivery rate, wherein the delivery rate is 0.28 g/sec to about 0.45 g/sec; and wherein an ejected composition is sprayed, wherein the ejected composition comprises particles having an average particle size distribution (Dv50) of from 40 micron to 100 micron.
