Aerosol foam dispenser and methods for delivering a textured foam product

1. A method of dispensing a textured foam from an aerosol container comprising:

a. providing an aerosol foam dispenser comprising:

i. a pressurizable outer container for storing a propellant and a composition under pressure;

ii. an actuator where the actuator is attached to a top of the outer container comprising:

1. a valve being movable to an open position to release a mixture of the aerosol and the composition;

2. a trigger for actuating the valve;

3. a nozzle comprising a nozzle surface comprising one or more shaping orifices;

wherein said orifices are in fluid communication with the valve;

b. actuating the trigger;

c. dispensing a foam composition at a linear velocity;

wherein the foam composition comprises an elastic modulus from about 10 Pa to about 200 Pa;

wherein the method comprises a shape factor from about 0.11 to about 1.

2. The method of claim 1 wherein the shape factor is from about 0.12 to about 0.75.

3. The method of claim 1 wherein the foam comprises an α from about 0.1 to about 0.6.

4. The method of claim 1 wherein the linear velocity is from about 550 m/s to about 1935 m/s.

5. The method of claim 1 wherein the foam comprises an elastic modulus from about 15 to about 175 Pa.

6. The method of claim 1 wherein the foam comprises a stiffness value from about 0.1 to about 0.6.

7. The method of claim 1 wherein the foam comprises an instantaneous foam density from about 0.01 g/mL to about to about 0.4 g/mL.

8. The method of claim 1 wherein the composition comprises a shampoo composition comprising one or more surfactants, an aqueous carrier, and optionally a cationic deposition polymer.

9. The method of claim 1 wherein the composition comprises a conditioner composition comprising a cationic surfactant, a high melting point fatty compound, an aqueous carrier, and optionally a silicone.

10. An aerosol foam dispenser comprising:
