Aerosol hairspray product comprising a spraying device
First Claim
1. An aerosol hairspray product comprising:
- i. a container (100) comprising a container wall (110) which encloses a reservoir (120), wherein the reservoir (120) comprises from about 40% to about 70% of a hairstyling formulation and from about 30% to about 60% of a dimethyl ether propellant, by total weight of the hairstyling formulation and the dimethyl ether propellant;
ii. wherein the hairstyling formulation comprises;
(a) from about 30% to about 60% water, by total weight of the hairstyling formulation and the dimethyl ether propellant;
(b) from about 5% to about 15% of one or more hairstyling polymers by total weight of the hairstyling formulation and the dimethyl ether propellant, wherein the hairstyling polymer is water-soluble and has a molecular weight of less than 200,000 g/mol;
(c) is substantially free of ethanol;
wherein the hairstyling formulation has a viscosity of from about 2.5 cSt to about 5.5 cSt;
iii. a spraying device (200) attached to the container (100) for dispensing the hairstyling formulation (180) from the reservoir (120) of the container (100);
wherein the spraying device (200) is fluidly connected to the reservoir (120);
wherein the spraying device (200) comprises a spray actuator (150) and a valve (130);
wherein the valve (130) comprises a valve housing (140);
wherein the valve housing (140) comprises a vapor tap (160);
wherein the vapor tap (160) comprises a vapor tap area;
wherein a dip tube (170) is fluidly connected to the valve (130);
wherein the dip tube (170) comprises a dip tube orifice (175);
wherein the dip tube orifice (175) comprises a dip tube orifice area;
wherein the ratio of the vapor tap area to the dip tube orifice area is from about 0.063 to about 0.15;
wherein the vapor tap area to dip tube orifice area ratio results in no clogs according to the Aerosol Spray Clog Measurement Method.

Abstract
Described herein is an aerosol hairspray product including a container including a container wall which encloses a reservoir. The reservoir includes from about 40% to about 70% of a hairstyling formulation and from about 30% to about 60% of a dimethyl ether propellant. The hairstyling formulation includes water, one or more hairstyling polymers, and from about 0.05% to about 2% alcohol. A spraying device is attached to the container. The spraying devices includes a valve including a valve housing including a vapor tap including a vapor tap area. A dip tube is connected to the valve. The dip tube includes a dip tube orifice including a dip tube orifice area. The ratio of the vapor tap area to the dip tube orifice area is from about 0.005 to about 0.15.
