ABSTRACT
Mousses use a propellant (pressurized gas) and a surfactant in addition to water-soluble styling polymers to help create a smooth, creamy foam. When the consumer shakes the can, liquid propellant is mixed with the water-based liquid concentrate. Then, when the can is inverted and product is dispensed, the pressure of the vapor propellant pushes the mixture of liquid propellant and liquid concentrate out of the can. The liquid propellant then quickly evaporates, creating foam. The mousse foam makes it easy to apply the styling polymers to your hair because in the foaming state it can be spread very thinly. This makes mousse great for long hair that would be weighed down by large clumps of polymer. Another benefit of mousse is that it its foamy state it is not runny and thus will stay where you put it-making it another good alternative for adding root lift to a straight style.
