Problems solved by technology

However, changing one or more characteristics of an aerosol hairspray product can be challenging as the interrelationships between them affect product performance
For example, the use of different propellants or different spraying devices may result in unacceptably lower packaging operating pressures, resulting in increased moisture in the product at the time of application, or may result in unnecessary clogging

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 sprayingdevice 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.

Description

technical field [0001] Described herein are substantially ethanol-free aerosol hair spray products comprising a dimethyl ether propellant and having an aerosol cock area to dip tube area ratio of from about 0.0005 to about 0.15. Background technique [0002] Hair styling products such as hairsprays are used to achieve different hairstyles and to hold locks of hair in place for a period of time. Typically, hair gels comprise film-forming polymers that form fiber-fiber fusions when applied to keratin-containing fibers such as human hair. These fusions "bond" the fibers together and thereby impart hold to the style. [0003] Aerosol hairspray products typically contain a pressure-resistant container, a nozzle, a propellant, and a hair styling formulation. Hairspray compositions are usually sprayed from such products via aerosol-forming nozzles. Alcohols are commonly used in hair styling formulations, for example to lower surface tension. However, high proportions of alcohol...
